PSU Recommendations.

[Novartic_]

Hello all.... I am looking for a reliable, good looking, stable in the volts when under load power supply. I would like to have one that you can disconnect and add in extra cables etc.. depending on what I need. (would also like one with a 120mm fan on the bottom, if not dw..)

 

The hardware that I will need to run is the following:

 

// Asus Maximus Formula

// CoolerMaster Stacker STC-T01 + 4x120mm, 3x80mm fans.

// Thermalright Ultra 120 extreme + 120mm fan.

// Core2Duo Q6600 OC @ 3.2 GHz

// Two ATI HD 3870 Crossfire cards in CF mode.

// 4GB RAM... dont know what to get yet for this..

// 2 x WD 78GB Raptors RAID-0 -OS

// 4 x WD 250GB RAID-5 -Data

// TWO OPTICAL DRIVES!!! -- update!!

 

TV card in the future..

 

Will need to be able to power WC if needed and future proof. Must not exseed £160.

The rig looks good, im going for more or less the exact same and Im going to be using a Silverstone Decathlon (available in 650/750+ versions). I originally wanted a PcP&C, because of the single 12V rail, but I also wanted something modular. The Decathlon series has both (modular and single 12V rail).

 

Let us (me) know how the build works out for you!

[Novartic_]

so.... You recon I should use a 750W as well right??

[powsmowl]

I dont know, Im going to be using the 650W version for the Maximus, 2Gb Ram, E8400, 2 3870s, 2 HDDs raid 0, dvd rom, a sound card and 3 fans, which it will be enough for...so in your case..yeah Id go for the 750W

I will 2nd that recommendation. Get the SilverStone Decathlon DA750 (750 watts) PSU. I have this PSU (see sig). It's a solid performer as well as it's 100% modular.

"They claim modular plugs add as much electrical resistance as would occur in an additional 2 feet of standard wire, which leads to a relatively big voltage drop."

This true??? If it is then im like,.. jog on..

[Guest Lavell]

I'm not sure how true this is with other PSUs, but I can tell you that is not the case with this particular PSU. In that review you linked, during testing the PSU had a small drop of voltage (from 12V to 11.75V). That's only a .25 of a voltage drop due to modular cables. I never measured the voltages on my PSU, but I would bet that if I did, I would get similar results.

 

There's not that many high-powered single-rail PSUs out there on the market. Having said that, I still stand by my recommendation. This just might be the last PSU you'll ever need to buy. It is for me.

True. So then should I just get a Galaxy 1000W in that case..

[powsmowl]

1000W is overkill for your system.

[Novartic_]

ok, what about the Galaxy 850W? Only Price ex VAT: £122.00, Price inc VAT: £143.35

[powsmowl]

Why the galaxy? PSUs with single 12V rails, like the PCP&C and Silverstone Decathlons are stabler and should cost roughly the same amount as the Enermax

[soundx98]

IMO just about any quality 600W PSU will do the job well.

We are very fortunate that there are a lot of decent PSUs available.

Some popular models here in the States may not be available to you (or cost an arm and a leg).

 

Pricing in the U.K. may boil down to has the strongest distributor.

Move more volume, you can sell for less.

 

Now I think I just bought the PSU you are looking for.

It's a Corsair HX-620.

Modular, ton of current, rocket solid voltages - the reviews have been fantastic.

And it's "pliable" modular cable design that is flat.

Pretty spiffy.

Be firing it up this weekend.
