Please bear with us as we change the format of this thread to include power supplies for ALL platforms and motherboard brands.

This guide was originally built for DFI-Street and most for DFI Lanparty NF4 customers. Since we have expanded our format, all of the information is still very much valid, but we have to keep this as a work-in-progress to help it move away from DFI-specific into a more general guide.

Thanks!

UPDATE: October 20th, 2006:davidhammock200, Happy_Games, ExRoadie

This list of recommended power supplies only applies to hardware available in North America and tested by DFI-Street.

Enermax Liberty 620w PSU is no longer on our recommended list. Way too many issues with this power supply. DO NOT BUY TO USE ON DFI SYSTEMS!

Also note we've added the Corsair HX-620 (620w) psu and I can honestly say it is EXTREMELY recommended as a top psu, and we've added 3 Antec units, and a Hiper unit!


All of the above are EXCELLENT PSU's & are THE MOST HIGHLY RECOMMENDED!

My personal choice for the most demanding systems is the Corsair HX 620W from only $150!

If you are NOT running UBER SLI/CF, then the Corsair HX 520W is my #1 choice from only $105!

If you have the bucks ($549!), the new PC P&C 1KW-SR (Single Rail: +12V@72A) is one of "THE BEST PSU's MADE".

My personal choice for "BEST BANG for the BUCK" is the OCZ GXS 600W for about $85!

One special note, if you require extreme quiet the the new Seasonic M-12 600W/700W should be available soon!.





REMEMBER NATIVE 24-PIN ATX CONNECTOR & 480W's OR MORE!

Found this interestingPSU Recommendations for High End Gaming PC's

it will definitely be a nice change to not have to constantly recommend $100+ psu's for DFI systems.

I still will refuse to recommend anything like ULtra or Aspire unless they make something quality, but now we'll be able to test the $35-$75 range since we will get to try them on a good number of setups for all range of users.

Sounds like a plan:cool: . Guru runs some interesting reviews.

Well I don't know how much stock to put into this guide line but here is a power usage estimator link if you'll think it's worth having http://extreme.outervision.com/psucalculator.jsp As well as a basic power supply tutorial. long winded one at that http://www.hardwaresecrets.com/printpage/181/1

I got to admit I just don't put any thought into these 'psu calculators'.

I tend to live along the lines of "I will buy something that I know is good, which means a $30 psu is not going to power my SLI or Core2".

ie based on the cpu and gpu I am running is how i choose a psu. There's no real rhyme or reason, its just experience.

I've seen some kick-ass $50 psu's. I've seen some mega-horrible $120 psu's.

brand/quality is more important than the sticker on the psu giving out it's specs.

This is why we trust OCZ, Corsair, PCP&C, Fortron, etc, and we don't trust Aspire, Ultra, Rosewill, etc.

got me new ocz gamestream 850 watt psu:)

I bought the Seasonic S12 600W, based on reviews from the likes of TomsHardware, Viperlair, bytesizedreviews, Hexus, silentpcreview, custompc and PCSTATS to name a few.......

In all these tests its been able to show just how good it is........ However, in the DFI street recommendations its NOT recommended for Dual Core +SLI setups.......... Im not running SLI (Yet) but i am having issues with PRIME95 STABILITY !! Could the PSU be my problem ?

Basicly if it is not DFI accepted it is crap.

By the way those Ultra PSU's -ARE- crap and I had two 600's die on me in 24 hours and sent the whole shipment back.
You can't pay me (well perhaps if you offered enough) to even accept a shipment of them for any company I might work for....but I would end up still sending them all back!

I don't think I would go as far as to say that. Lower end pc's do not have the same power requirements as a DFI.

But that does not make the PSU any better does it?

By the way....what is a "lower end" PC today?

I used to mostly only use ASUS and Antec to build high end computers yet today I would never use either of them.

I would call Antec a 3'rd tier PSU today.
ASUS would be a non use item for me period.

my Antec is rock solid and has been for a while. Yes they did have problems before with SOME of their psu's but that does not mean they can't make good stuff today.

Lower end would be a non overclocked single core and a single mid range vid card. For this kind of system a subpar psu that is not recommended for a DFI would be just fine. And i'm not talking about some 2 dollar psu but like an ultra, cooler master, thermaltake...etc

the S12-600 was a pretty good and very silent psu, but it never was able to handle the hardcore DFI + SLI setups

I retired mine to my server, a 3.4Ghz P4 Northwood w/2GB RAM and about 1TB of drives lol


as for the statement of "Basicly if it is not DFI accepted it is crap" is not anything I'd go running around shouting (because it just isn't true).

I'm more of the mind that the DFI boards required such high power requirements because they weren't really as well made as other boards that didn't require such high-end units to really accomplish the same end result...

Do a search for my posts in the PSU section.

I always used to use Antec....but not now.
The point of failure for them is the same as for ASUS MB's.....the caps.

Well the point here might be if it is not "accepted" it might not be 100% crap but it sure as hell is not the best choice.

I really doubt you would recall all the PM's I sent to you befor I got down to building my first DFI setup....but I went against the OCZ and even did not opt for a Silverstone like Falcon uses.

The heart and soul of every system is the PSU and after much research I went with what is in my sig...but really those Ultra PSU's are nothing but crap!

As they say "your mileage may differ".

You can't fairly judge every psu without testing each and every single one yourself...which I'm guessing you haven't right? The ultra x infinitys are decent psu's. You can't just judge a brand for making one shitty psu. Sometimes companies learn from their mistakes.

ULtra-X and Aspire psu's aren't worth $2 on any rig honestly

putting them in your rig, regardless of what rig you run, is like playing russian roulette except instead of only a single bullet, you only get a single empty chamber (ie 5 bullets instead of one lol)

There's no way I would ever even consider an Ultra psu for the weakest cheese system that was going to be given to my worst enemy.

I just got my new SLI-DR MB and now i have to buy new PSU also bc of the ATX 2, i'm thinking about to buy Tagan easycon XL V2 600W ATX 2.2.
What you guy's think about this one, is there anything i should know about?
THX in advance
DEDE

For the system I have, my PSU provides way too many cables for my needs. Hell when I had a friend help me out make this computer, I didn't know if it was going to be enough power or too much. Hasn't messed up on me and I've had it for 3 years now so I can't really complain about it but the amount of cables. Anyone that buys this PSU, have a big roomy case for it.

Hi there i have a DFI LanParty UT RDX200 CF-DR Motherboard

I am posting as i have for ever experienced a problem of when i shut down my computer and the whole computer powers off the computer after a couple of seconds reboots.

I have tried changing my Power supply unit from a ColorSit psu running at 550w to a brand new Hipper Type R series 530W which didnt effect weather it decides to reboot or not.

The computer reboots around about 9 out of 10 times the other 1/10 times it turns off correctly. I have been on the DFI forums and they told me to change a pin and disconnect a Ethernet cable which i did then after i replied saying it didnt cure the problem they told me that the psu i had before the ColorSit wasnt a supported PSU....

is my new one also not supported?
or
is there any thing i can do which will cure the problem other than buying a new motherboard and PSU?

Thanks For you help
Karl

AFAIK (which isn't far) your new one should be alright. The ColorsIT is on the brands to avoid list linked at the top of this thread. Guess maybe one of the Wake On x options in BIOS?

on t (and unrelated, himmerz, just a btw) - the 'multi-rail supplies' thread is very interesting, and clears up a couple other points, like load balancing. Linkage/Sticky/similar? :tooth:

hi I am about to check the wake on options in the wake options in the bios, and i don't think its multi rail i don't really knew what that is, is it to do with how its mounted in the case? I will probs check that thread out latter when i have the time cos im about to go out.

Thanks for your reply :-)

Karl

i couldn't seem to find that option in the bios after searching all areas of the bios, the DFI team said it should be the psu leaking voltages with the colorsit one, but i really doubt hipper would be like that cos there like expensive and a really good make.

Reply from there first reply doing instructions they told me:
I Have moved the JP5 to 2-3 and removed my lan cables however when i shut down about 1/3 times the problem is resolved but the other times it does still decide to restart just as you think its turned off.)

DFI Teams reply back (about the colorsit one)
That PSU could definately be part of the problem. It is not one that DFI recommends. The thing is that motherboards with an ATI chipset have low trigger values and if coupled with a power supply that could be leaking voltage this can cause the system to suddenly spring on. I would advise trying a recommended PSU from this list http://www.diy-street.com/forum/showthread.php?t=73137

I do like the dfi boards but they seem to be off putting if this is there reason and if there limiting to psu's surly they shouldn't release it like that, thats like releasing a operating system that can shut down properly, Are all there lanparty board like this?

Any more help i would greatly luv cos i hh8 having to turn my pc off at the wall or the power button i don't wanna damage any parts.

Thanks Karl

Please post a proper sig, so we have some idea as to what we are dealing with! :cool:

kk soz my bad, hav done so now

I've not had any issues with my Enermax Liberty 620W :sweat: and hopefully will never have unlike my old Colors(h)it 550W :sad:

i will probs go core duo and avoid dfi when getting my next mobo then cos i luv my hiper psu it connects like a knife in hot butter to power connectors

For DFI mobos, consult the Official DFI-Street PSU Guide:
http://www.diy-street.com/forum/showpost.p...853&postcount=2

What do You guy's think about the coolermaster PSU's.

I'm Now using a Coolermaster Realpower 550 Watt SLi. But i'm having some stability issues dont know if its the cpu. So i'm gonna install a corsair today to test is. But i'm looking for a new PSU with the new 8P PCI-E Connectors.

I love the coolermaster PSU's in power usage. They consume's less power then other psu's. It seems they have a high efficiency. But the website tells me the PSU ( Coolermaster Realpower Pro 850/1000 ) Have 6 12v Rails. And from the post above its seems to be a bad thing.

http://www.coolermaster-europe.com/index.p...l%20Power%20Pro

Would you guy's reccomand This PSU ? I want a PSU that can power 2xR600 cards and the new AM2+ mobo's with quadcore barcelona. ( My up-comming setup )

I do not recommend any Coolermaster PSU's & efficiency ratings are published.

I'm sorry to say that at this time we do not really know how much power a pair of R600's are going to pull,
therefore our only safe corse of action is to recommend the PC P&C 1KW-SR, as PC P&C guarantees its performance.

Good Luck,
Dave

Double posted Sorry.

Well i have tested The Corsair 620 Watt VS my Realpower. And The System is rock sollid now. Coolermaster had some cold boot problems.

But the Power usage from the System with the coolermaster PSU was 185 Watt and with the Corsair is used 210 Watt. Quite a difference.

I saw my Coolermaster Had a Peak of 18-20-10-A on the 12v rails. But it can only do 12-12-6 all the time.

For the corsair its 18-18-18 Peak so i guess it also had a Max of 12. So i guess i should be looking for a PSU with one Big rail and the 8P PCI-E connectors. I know the new Enermax Galaxy and Liberty's already have that new Connector. But they also have split 12V rails :'(

Can Anyone Tell me What the next image means:



620 VS 520 Watt both have 3x 12v @ 18a Max. But what is the continues output of theses 12v rails ? Corsair is talking about a combined power of 50A thats still 600 Watt.

And what are the bad things about the Coolermaster Realpower Pro PSU's of 850 and 1000 watt ? To weak 12v lines ? They are rated @ 6x18A Max output. The Corsair i have now had 3x18A Max. But the 850 watt coolermaster only has 230 watt more and 3 more 12v lines. + 12vx18A=216 Watt per line 216x6= 1296 Max for the 12v only. So the values they give are not to be trusted.

Same With the P&C 750 Watt. It has 60a 12v raild thats 60x12= 720 Watt for the 12v rail only. I think thats a peak value. But i dont think that coolermaster 850 can peak 1300 watt on the 12v only.

And then the next thing:



Is this even possible ? And if it is it seems logical other PSU's like the Galaxy and Realpower Pro would also have something like that.

And What do you guy's think about this new PSU: Galaxy DXX 1000 CrossFire

http://www.enermax.com.tw/english/product_...ay1.asp?PrID=70

It already has 2x8p PCI-E connector + 18P cpu connector and 4x6P PCI-E. The R600 will need 1x6P and 1x8P PCI-E. ( That was the latest info. Or ATi has changed the PCB and Power requirements to it can run on 2x6P )

But This PSU has 5x12V rails of 24A Rail 1 and 2 are combined to 408W (34A) And Rail 3-4-and 5 are combined to 492W(41A).

The Corsair 620W has "up to" +12V@50A.

The PC P&C 750W Quad has "up to" +12V@60A.

The Silverstone OP 1000W has "up to" +12V@80A.

Yje Corsair is powering your PC, the Coolermaster is not, the Corsair is 80%+ efficient.

True. My Coolermaster can power it but not @ cold Boot after 10 min it runs good. But yes i think the corsair is more stable. Could explane the power usage.

But What about those 3 rails of the Corsair. Is it possbile they are linked ? So can i see it as a Big 12v rail ?

Because in a other post you had a Quote from P&C that said that a singel 12v Rail in better then 4 weaker 12v lines.

And What are your thoughts about That Enermax Gallaxy DDX Crossfire PSU ?

Sorry For all the question. But i'm trying to figure out how i can identify a good PSU by myself and what is better to buy. Because P&C says more 12v Lines are Bad. Corsair says that they ave separate lines that can be linked if more power is needed. So i dont know what's good or bad. And whats true.

And i see ppl replacing Seasonic PSU's for OCZ and solving there problems but the Antec and Corsair PSU's are build by Seasonic :\ And the Corsair is highly reccomanded. They bought a wrong Seasonic PSU ?

The Corsairs, Antec HE's & Trio's & the Seasonic M12's are in reality single +12V rail PSU's,
as there is no "per rail" current limiting.

These are all very good PSU's & are highly recommended.

Top of the heap, no doubt, goes to the PCP&C Silencer 750. I'd also not hesitate to recommend getting on of the refurbs of any of the PCP&C models listed HERE. $30 off a 750 Quad is nothing to sneeze at, and I have the utmost faith in PCP&C backing their products, refurbished or not.


For the budget boxes out there, I have had extremely good luck with Thermaltake TR2 W0070RUC 430watt PSU. I've used 5 of them to date, between the wife's rig, and 4 customer builds. I have had no failures with any of them, and have even gone so far as to put my X1900XTX and a total of 4 HDDs in the wife's rig, and it still ran problem free. They usually go for about $40, but tend to go on sale (or w/ MIR) for about $25.


Some brands I've had bad experiences with:

Antec - I've had two fail on me in the past, both 550watt TruePowers.
FSP - I've seen three with pretty shoddy 20/24 pin connectors, where the pins would routinely push through the top of the connector when pushed down on the board.
POWMAX - Look up 'crap' in the dictionary, and a picture of any POWMAX PSU should be next to the definition.

Since last week I own a DFI Lanparty UT nf4 Ultra-D now and I guess I have to look out for a new PSU because my 480W Antec PSU doesn't have a native 24pins ATX connector which can only supply 22A max. on the 12Volt rail, a bit less I guess

I've read a lot of interesting stuff over here and I'm still a bit confused,.. single rail... multiple rail 12Volt rails ... which is the best :confused:

I'm not planning to run SLI,... I will do some heavy overclocking on my Dual Core Opteron 165 for sure,.. currently already running 2700Mhz. 9x300.
Which PSU do ya'll recommend to work fine with my rig. ,.. is future safe, has sleeved and preferable non-modular cables,
It's because I don't know what to think about those modular cables,.. I've read some stuff about problems with those cables ..... I don't feel so confident about those, voltage drops, bad connections ... stuff like that :confused:
Please a bit of advise

I have both the OCZ gameXstream 700 and the Corsair 620. Both of them are great PSUs. I would pick the Corsair over the OCZ though just because it does have modular cables and performs great. But either one of these would be good choices.

The CORSAIR HX Series 620W costs 149€ over here in belgium,.. should be like 193 US $
If I compare it with the OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply,.. that one cost only around 100€,.. 130$ US or so.
I guess I'll pick me the OCZ then.

But then you have to ask yourself, is it worth the extra to have a well built Seasonic over a newer model Fortron? I think OCZs are still based on fortron.

I wanted to buy an FSP550 for myself. Tech specs always show 200 mV ripple on 12v rail to be within their spec, which irks me. http://www.nexths.it/v3/flypage.php?mv_arg=FSP550-80GLC

I guess the upside is they rate their stuff to 50c. It takes some work to find this, but some sparkle models have the temperature/power on the side.. usually 50w more than what they are specced for is 30c, and what they are specced for is at 50c. I'm no expert, but I think the spec is around 140-170 for ATX2 on 12v rail badunkadonk.

I had a LANParty UT nF4 SLI-DR Venus with the Enermax Liberty 620W.
(BTW, I bought the board and PSU BEFORE 10/20/06)
Had it for over a year and didn't experience any issues at all.
Maybe I was indeed one of the lucky ones.
Who knows...
The point is, I now have three concerns:

1. What kinds of issues did this power supply cause with that board?
I sold the board to a friend of mine and it's running perfectly fine right now.
He's using his old Enermax EG565P-VE on it.
If there's anything he should be prepared for, please, do tell.

2. Is it safe to use that same PSU on another board?
That PSU is currently (no pun intended) powering an Asus A8N32-SLI Deluxe.
This board is also running great ATM, but I'm planning to sell this entire rig and finally start my QC build.
But if there's anything I should warn the buyer about, please let me know.

3. Is it safe to use that board with another PSU?
In the event that it isn't safe to use that same Enermax Liberty 620W with this Asus A8N32-SLI Deluxe,
I'd like to know if I could just purchase another PSU and not have any problems.
Rather than having to buy a new PSU AND a new board.

I know this sounds crazy and I'm probably taking it overboard.
But I have OCPD, so I can get away with it. =P
And yes, I have read "The Post."



But I don't think this really falls under the category of "DFI support."
As I said, the DFI board is running perfectly fine with the EG565P-VE.
In fact, the only thing that really pertains to DFI is the question regarding the 10/20/06 post.
I mention this, because I know this is one of Angry_Games's pet peeves.
>>So, sorry if I messed up sir. /=
Anyway, if this post gets deleted, I'll know why... =P

Thanks again!

Surprised that my PSU (SilverStone Strider ST60-F 600W) never made the list, nor any of the other SilverStone models, is there an issue I am overlooking? I know a few people who love these PSUs. In my opinion they aren't too expensive either.

edit:



I need to read better sorry

So, the Corsair PSU does perform well with DFI-boards .... right :confused:
And it does have a single 12Volt rail never the less the label on the PSU says 3x18A for the 620W, same for the 520W model.
I also see that the only difference between the 520W and 620W PSU the 6Amp. difference is on the 5Volt rail.
For which things is the 5Volt rail important :confused:
Will the 520W model be sufficient for my sytem and still be future ready :confused:

Price of the Corsair 520W is reasonable over here in belgium, 108€ (143$). The 620W model costs 41€ (54$) more.

Hey guys, hows it going! Over at Jonnyguru's site, Jonny tested the 700W game extreme of OCZ and everything was awesome with it except for one glaring problem: significantly high ripple as loads got closer to and up to rated full loads. The rails for the CPU and the miscellanious rail saw ripple as high as at least 150mV!!! That is NOT good. He then tested a fortron that is the same unit and ocz even sent him another to test and it did the same as well.

Ripples like that can be murder on regulation and more for the motherboard etcetera.

Any opinions here?

My BOLD for emphasis!

Could you please quantify a good deal of ripple in a technical measurement?

So the bottom line is that the ripple measured at normal output isn't a problem.

You want as little ripple as possible but obviously it's not the only measure of a quality PSU.

See my sig for what I've been running for over a year now.

Will my PowerStream 520 power an 8800GTS?

ExRoadie, you make it sound like I didn't read his review, why then am I referring to it.

Sure, 400 watts and less would be more likely the norm, but if that, why own that high a power supply, unless you are trying to increase service life? The bottom line is that it went above acceptable spec slightly when driven hard enough and most of the other higher end supplies have not done so, so it IS something to be aware of. You are welcome to say: "I have smoked, jumped from airplanes, walked on railroad tracks all my life and nothing ever happened!" But that doesn't make those things safe. It is harder on you electronics to have ripple. Ripple is always there, all that can be done is to mitigate it, but this OEM doesn't do that as well from my readings thus far. The ripple will wear out regulation on your motherboard all that much sooner, it's a law of averages issue.

It is a fabulous supply though.

Could you all consider adding the Enermax Infiniti to the approved list. It is a fantastic supply with low low ripple, super stable voltages, quiet, good looks and quality build, SLI/Crossfire, and very temperature tolerant (40 d C rated).

Here are two reviews of it:

(That is MY ACTUAL supply that was tested there)

Originally I was going to buy a refurbished PCP&C Silencer Quad 750 but I was "talked" out of it, heh. Yes, a VERY good supply indeed, but what I did get, here, is awesome too.

There has been one person on newegg complaining about issues with modern breakers on new constructions homes, but Enermax says they have tested and don't see the problem, so I don't know where the issue has landed. The guy is complaining about Arc Fault protection tripping from this supply, but I have not seen any other comments on it and I don't have that at this house, so I cannot test for it.

The only drawbacks on this supply are:

There are 3 PCI-Express connectors, but just one is 6/8 pin, the other two are 6 pin.

The cabling is shorter than it should be.

The power cable is too short.

The sleeving isn't all the way.

Natrually, I am not pushing this supply hard, but it WAS tested really hard, so...

It has some cool features such as a signal LED and beeper, fan cool down power off mode, brushed metal case, clear fan that is 135mm and very quiet, carefully labeled wires for safety, other things as well.

Ripple was less than 50mV at hard full+ load on the +12VDC rails which is quite good.

In a hot box the rails hardly budged (though he had to use cable extensions, so readings were affected).

I don't know what it is about the Liberty, and yeah, I just got this, but so far I am loving it.

As someone who is currently shopping for a new psu, this is the most useful and informative thread i have ever seen. Keep up the great work. I am new to this site, but i read everyday now and I love it!
