The Big Giant Power Supply Thread

Recommended Posts

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.

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!


UPDATE: June 14th, 2006


DFI-Street.com Certified (ie: HIGHEST RECOMMENDATION)


OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply

(personally tested by Happy_Games. This and the OCZ 700w GX are my two favorite psu's!)


OCZ GameXStream OCZ700GXSSLI ATX12V 700W Power Supply

(current top-rated, top-recommended psu by Happy_Games and majority of the forum!)


FSP Group (Fortron Source) Epsilon FX600-GLN ATX12V/ EPS12V 600W Power Supply


FSP Group (Fortron Source) Epsilon FX700-GLN ATX12V/ EPS12V 700W Power Supply


Corsair HX620w ATX12V v2.2 and EPS12V 2.91 620W Power Supply (Active PFC)

(quickly becoming Happy_Games' favorite psu. Modular, strong rails, low-heat, nearly silent...excellent excellent unit!)


PC Power & Cooling TURBO-COOL 1KW-SR SLI, EPS12V, SSI 1000W Power Supply 90 - 264V


Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails

(personally tested by Happy_Games...excellent choice for X1900 Crossfires / 7900 SLI's!)


These PSU's are all very very capable of powering up the latest 7900GT and 7900GTX SLI, 7950GTX, X1800XT and X1900XT Crossfire, AMD AthlonX2/Opteron Dual Core cpu's, and ALL current DFI motherboards including the following:


DFI Lanparty NF4 series original

DFI Lanparty NF4 Expert

DFI Lanparty NF4 Venus

DFI Lanparty RDX200 (ATI)

DFI Lanparty CFX3200-DR (ATI)

DFI Lanparty future AMD socket AM2 motherboards of all chipset flavors

DFI Lanparty future Intel Conroe motherboard of all chipset flavors


These are very reliable psu's that are more than capable of doing the job.


Notice that the top 4 are almost identical (the OCZ and Fortron/FSP psu's). They are all manufactured by Fortron, and are the highest recommended psu's in the forum as they have the largest user base, and the least amount of complaints.


I always recommend the OCZ psu's since we have a few OCZ reps in this forum who have always been more than willing to help out mutual customers (and they have even helped out non-OCZ customers!). The only real difference between the OCZ and FSP power supplies is the OCZ psu's have a blue LED fan, and the Fortron psu's do not have any LED fans.


And finally, the 1000w PCP&C psu. Everyone should by now know that PCP&C is the maybe the top name in power supplies...but you pay a premium for them.


The 510w version is extremely solid, but we simply cannot recommend it for the highest high end setups like those mentioned above. For that, you want to have any of the psu's on this list, including the PCP&C for your ultimate power needs. If you can afford this thing, you definitely want it.


Again, if you want a solid power supply that is reliable, trustworthy, and a growing majority of the users here are turning to, choose one of the OCZ GamerXstream power supplies. My personal favorite is the 700w (see the sig of Happy_Games)

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: [email protected]) 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!.


DFI REQUIRES native 24-pin ATX molex & 480W for all the DFI N4 mobos.

These are KNOWN to work well with DFI N4 mobos, DFI ATI motherboards, including Expert, Venus, RDX200, CFX3200-DR!!

$229: http://www.pcpowercooling.com/prices/


OCZ PowerStream 600W WARNING: The OCZ Powerstream 600w is a fantastic power supply but it is NOT recommended for X1900XT/7900GTX or newer Crossfire/SLI. Avoid if you plan on using them in X1900XT Crossfire or 7900GTX SLI, or any newer Crossfire/SLI setup! Other than this particular combination (Crossfire X1900 / SLI 7900 or newer), the OCZ 600w Powerstream is a fantastic psu and is highly recommended.


From $179: http://froogle.google.com/froogle?tiled=1&...=Search+Froogle


These power supplies are MORE than capable of ANY setup with a single video card, 7900GT SLI, X1800XT Crossfire, or lower.

Antec NeoPower NeoHE 550 ATX12V 550W Power Supply

(personally tested thoroughly by Happy_Games and it is an excellent psu. Not recommended for highest-end SLI/Crossfire (X1900 / 7900))


HIPER HPU-4K580-MS ATX12V 580W Power Supply

(personally tested by Happy_Games. No 8-pin EPS connector so not recommended for any board with the 8-pin EPS connect. Works most excellent in any other system. Not recommended for high-end Crossfire/SLI but will handle any overclocked system with any single high-end video card, or any mid-range to low-end SLI *7600, 6600, X1600 Xfire, etc*)

These quality brands offer "known good" PSU's,

however not every power supply they offer will meet your needs,

be especially careful to make sure that the +12V rail(s) offer a

Why do people buy these? :confused:


There are PSU's for under $30/$40 in the "Complete PSU Guide" with more +12V amperage!


These 2 TT PSU's are the "poster children" for DFI's 480W+ requirement &

based on these it should be a 600W+ requirement! :rolleyes:

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.

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-butt $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.

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.
