650W Corsair PSU enough?

mattius1989 · 27 Feb 2013 at 18:33

I am probably going to pick up another 680GTX towards the end of this year and just wanted to know whether I will have to get a new PSU when I do or will what I have already be sufficient for power?

Also, what's the average life expectancy of that sort of PSU in a gaming PC that gets around 5 hours of use each day?

SLI 680's I would look at 750W.

Or get a Seasonic G/X series 650W.

well it all depends on what make and seasonic are about 5 years

try this to calculate how much power you need

Im guessing his Corsair is a CX, HX or TX model with a 3 year warranty so they prolly last around 5 years before the caps start wearing out me thinks.

Those ranges AFAIK are made by CWT, Flextronics etc.

A Seasonic would last at least 7 years to my reckoning since they already have 5 year warranties.

Yep you'll be fine unless you're thinking of OCing

Thanks for all the replies thus far.

I have overclocked my 3570k (only via the multiplier) and the 680 is OC'd via the boost (no voltage). Looking like a new PSU may be in order anyway then, as it has been running for about 2.5 years...

If not Seasonic, XFX would also be a good choice as Seasonic make their PSUs too

You could get away with your PSU as Andantech got 536w from running SLI 680's and this includes the system.

Doesn't Corsair provide a 5 year warranty? Or is that only more recent PSUs? I also thought they used the same internal components as Seasonic.

Sorry yes its the CX range with a 3 year warranty and the others with a 5

Corsair only use Seasonic on three of the AX range if I remember correctly, the other models use cheaper OEMS.

Incorrect.

They've re-done their OEM's this year then?

Last time I checked a similar site to that late last year they only had 3 of the AX range and used a lot more Flextronic.

dacads · 27 Feb 2013 at 19:39

Not sure but tomshardware done an article this year and AX isn't the only range made by Seasonic

I'd be a little cautious running a pair of 680's on a 650W PSU and I'm usually the one posting 'you could run that on batteries'

You might get away with gaming but Furmark and Crysis 3 could be to much.

I can draw >650W from the wall socket in Furmark with a pair of GTX560Ti's so that's around 550W DC. Pretty much on the limit for my Corsair HX620.

In gaming it's a good 100W less though I hear Crysis is very hard on GPU's

I'd be looking at 850W for a pair of 680's
