Good day fellow OCN'ers, im currently flirting with checking out a quad sli setup for giggles. Thinking of using my sig rig, and pairing up a set of 295's was wondering if the psu has enough juice to safely use these behemoths..

The GPUs alone will take 550-600W, so I think that you will need an 850+ W PSU for that system.

The TX750W can deliver up to 940W, but I wouldn't risk it. Get a quality 850W+ PSU. The Corsair TX950W is $160, excellent for a 1kw PSU.

lets put it this way.

gtx 295 had one 6pin and one 6+2 pin

in worst case scenario
board pulls 75W, 6pin 75W, 8pin 150W = 300W x2 = 600W

You be fine with your set up but if your gonna load it 24/7 365 days then you might want to get a better PSU.

as for going dual gtx 295 at this stage is no recommended since new stuff are just around the corner

at legit review they have a i7 965 and gtx 295 quad sli and it pulls 726w under load.

Enermax 1050 watt or 1250 Watt. I have seen pics of the 1250 Watt Enermax Galaxy Evo running 4 GTX 295s for folding.

That is what the spec states they must be able to deliver. In reality the 6pin can deliver over 100W and the 8pin can deliver close to 200W....if the card so demands.

and the card demands 289W tops as stated in nvidia's specs.

Tdp is not a very good indicator of the most power the chip will consume. Tdp is the amount of power the cooling system can dissipate in stock form running regular programs. Exceeding tdp happens quite often, and this is why it isn't a good tool for calculating consumption. However, 90% of the time a chip is running way below it's tdp. Getting a 295 to exceed 289w would take some work on the users end, like a really high oc, or running a power virus.

The Corsair HX/TX850 would be enough, but I would suggest something with more headroom, such as the TX950 or the HX1000.

HX1000 would be good, but the TX850 *should* be ok. As said, the GPU's will only pull about 600 watts between them, and the PC on its own will use about 150-200w.

Expect a lot of noise from the PSU though.

The TX950W would be a good, relatively cheap choice.

Oops


I would recommend the HX 1000 over the TX 950 massively. Because the HX1000 is modular, cable routing is so much easier, and it's a lot quieter than the TX series.

As they say, once you go modular, you never go back.

As a reminder, Corsair has a 10 year warranty. Ship your 850 back to them, they'll replace it and you can sell it on OCN or ebay or whatever.

Actually Corsair has a 3 year warranty on their CX line, a 5 year warranty on their TX line, 5 year warranty on HX520, 620, & HX1000. They carry a 7 year warranty on their HX450, HX650, HX750, & HX850.

There is no 10 year warranty on their PSU's.

I too would rather have the HX1000 over the TX950, however that's due to the TX950's platform really being stretched to the limit, imo, for this PSU. If you need a 1KW psu, the HX1000 would put down that kind of power with ease, while the TX950 is way more efficient it just runs too hot and stressed out at it's upper output limit.

IMHO

Go with the corsair 1000hx, might seem huge but it will run anything you throw at it now and future proof too , Solid 12v rail

Im currently deliberating on the TX850, 950, and the HX1000. I am currently liking the 950 due to its compact nature. But as most of you said the 1K psu will go a long way for me. And no I didnt try to use it, and its had been acting/sounding strangely past month or so. Hoping for the best that it didnt fry or cook anything.

I'm currently contacting Corsair about an RMA since I just bought this Jan09. Sadly lost my reciept, and it was bought from a local store, we'll see how that pans out. My close friend just started to delve in the quad systems, with multiple GPUs. Assuming it RMA'ing attempt doesnt crap out, i'll just sell it to him.
