Good PSU?

[hamoood]

hi,

I'm planning on buying new psu.
What brand of PSU do u recommend?
IS 600W enough for my current specs?


Thanks!

It should definitely be enough seeing how most computers don't even use more than 300W when everything has been added up, 400 at most for a single GPU PC. What you need to look at is the brand and the quality of the PSU. One important thing to keep in mind is how many amperes it can deliver on the 12v rail, and how efficient it is.

Here are my suggestions:
NCIX.com - Buy Corsair CMPSU-620HX 620W ATX Triple 12V 50A 24PIN ATX Modular Power Supply 120MM Fan 2X PCI-E - CMPSU-620HX In Canada.

NCIX.com - Buy Enermax Infinity EIN720AWT 720W ATX Power Supply EPS12V V2.0 20/24PIN Crossfire Modular 135MM Fan - EIN720AWT In Canada.

NCIX.com - Buy Mushkin XP-650 650W ATX 12V 24PIN ATX Power Supply W/ PFC 80MM Fan - 550150 In Canada.

NCIX.com - Buy Silverstone Strider ST75F 750W ATX12V 24PIN Modular Power Supply W/120MM Fan Active PFC SLI Ready - ST75F In Canada.

NCIX.com - Buy Thermaltake Toughpower 650W ATX12V 24PIN SLI/CROSSFIRE Ready ATX Power Supply 140MM Fan Active PFC - W0104 In Canada.

NCIX.com - Buy Xion PowerReal 700W ATX Power Supply V2.2 EPS12V 20/24PIN W/ 140MM Silent Blue LED Fan - XON-700P14N In Canada.

NCIX.com - Buy Zippy GSM-6600P 600W Gaming Power Supply ATX V2.0 24PIN SLI Ready 80MM Fan Active PFC - GSM-6600P(G1) In Canada.

imo, i would get the mushkin PSU. It can power my 800watt subs with only 0.3v drop on the 12v. (12.02v highest to 11.9v when cranking it up.)

OCZ GamerXtreme 600w, love it

specs im running it on below

[ian209]

meh... i've heard bad things about the OCZ psus. My friend had the 600w GamerXtreme and it died in less than an hour of usage.

well your friend obviously got a bad one, ive had mine for about a month or so nearly always on, n not a single problem yet.

loads of psus die within an hour of use if they're faulty.

Seasonic and Corsair (made by Seasonic) make the best power supplies. I'd get a Corsair HX520W for that 8800. The Corsair is just a modular version of Seasonic's S12 series. It's one of the quietest you can buy and has a peek efficiency of 85% which is insane (80+ for any PSU is very good). Corsair HX520W & HX620W Modular power supplies | silentpcreview.com
Or if you don't care about modular you can get the VX450W or 550W for a bit less $$$

The only thing drawing serious power in that system is the 8800. Core 2's use much less power now. We won't ever see a CPU draw as much power as a P4 Prescott again. Most systems won't ever draw over 300W, here's an accurate online calculator...

I have heard good things about the 600w GamerXtreme, my uncle has one paired with a 8800GTS and he has never had problems with it.

[skoreanime]

I concur with the OCZ 600w. I've been using one for months and it's rock solid.

XClio X14 -650W

I'v been using it for a little over a month now, no problems whatsoever.

[ian209]

hmmm, a month is really nothing. My Mushkin XP650w has been powering my rig and my 800watt subs for a few years and it's still going. Whats nice about it is that it has real good quality components. The caps are VERY nice. After turning off the PSU, I can still run a 120mm fan for 10secs, until the caps are discharged. Also, mushkin had intelligently put capacitors on the CABLES them selves. the 6pin PCIe cable has 3 caps on the end of it. I dunno what the uF rating is, but from what my experiences say, those caps can take a mouthful in. Yea it is fairly high in price, but remember: What you get is what you pay for. It's hard to find a manufacturer that actually uses quality components in their PSUs nowadays.

[james.miller]

they corsairs are the pic of the bunch in that price range. they do excel at everything and come with a class leading 5 year warranty.

the op's pc would. mine uses 280w at idle

Cid is definitely correct. The amount of amperes it can deliver on the 12v rail is what you should look at when buying a new PSU. 400W is already more than enough, and some 300W PSUs can run high performance rigs. But aside from that one of my top recommendation brand for PSU is Seasonic. Their PSU are affordable and effective, as well as great customer service even in the RMA department!

I have an Antec TruePower 2.0 480W PSU and I have never been happier. It has been rock solid under my config. I do realize that I will have to get a new psu if I decide to go SLI. Which then I will choose the Corsair 620W psu. I love Corsair + Antec products. Never steered me wrong.

you didnt read what i said then? lol. my pc pulls 275-280w from the mains at IDLE. ie, doing sod all. it's easy to pull close to 400w with both the cores loaded up and running something like 3dmark.

400w is not more than enough, its barely adequate for a dual core/8800gtx pc.

[refraction]

i wish people would stop recommending 300-400 watts.

Nvidia state a minimum of a 500watt power supply for a system running an 8800GTX! anything lower would be suicide.

But for the breathing room and stability id honestly say pick a 600watt or something close to that (which is the recommended spec they give)

Well I stand corrected. But I'm still having the opinion that a lot of these requirements are so high because they aim to cover themselves against people who have these crappy 500W PSUs that can hardly give a stable supply of power to a Pentium 2 for the hell of it.

There's nothing wrong with being above spec with your GPU, but these KILOWATT psus are simply overkill for any system. Even a crossfired HD 2900XT with an overclocked Prescott doesn't need it.

I kinda disagree. Everything in your computer can draw quite a bit of power nowadays. Even my ToughPower 750w has troubles with my rig right now. It goes from something like 12.11v idle to 11.9v on load (multimeter tested). So I wouldn't say a 1KW PSU would be overkill. I mean, the HD2900XT already uses around 250w+ on load - and thats a single card mind you. The damn fan on the HD2900XT consumes 26w on max. My case fans go up to 20w. my 4 HDD's take about 40w. My pump is 50w. CPU is probably a lot more than 65w, since it's oced like mad; same goes with ram and mobo. Mind you this is all on 12v. If I went quad, or added another GPU, I would't probably have to get 1kw PSU's

Wait for Yorkfield instead, ~20% lower power consumption compared to Kentsfield.
