Recommend a PSU -2500k/SLI 460. - Page 2

I might just go with one of these:

XFX XXX Edition 650w £75 delivered. Green fan is the only thing putting me off, but a great price.

Corsair Tx650V2 £65 delivered. Not modular though.

Hey one question, with this PSU would I have any problems benching? more specifically for hwbot submissions, suicide runs etc?

I'v ordered it already, however, im not sure why but im not fully convinced.

I feel like maybe I should cancel it and just get the TXV2750 V2 for £10 more.

EDIT: oops sorry just realised I triple posted.

It's enough. Even with those overclocks, it's not like a i5-2500k is going to take 200W or anything like that. XFX XXX Edition is plenty decent:

http://www.jonnyguru.com/modules.php...tory3&reid=181
http://www.hardwaresecrets.com/artic...ly-Review/899/

The only quibble people have is the very weird and out of spec 3.3V/5V-heavy crossload (more than impossible to pull off on a modern system) result, as seen in the JG review. As you can see, voltage regulation is about 1% for +12V, about 2% for the others, and ripple is good too. It can handle full load at 50C fine, and your setup is not quite going to reach 650W even in the very worst case LinX + Furmark scenario.

cool, thanks, any idea how much wattage SLI 460 at 1.16v will be?

EDIT: Im thinking the GPU's alone at 1.16v and overclocked to 960core will some be around 350-400w in furmark?

EDIT: Phaedrus2129 where you at dude?? Would like some advice from the PSU guru himself

650 is plenty for SLI 460s, it really is, and that XFX will do it nicely, even with a decent overclock. I'd say you can possibly hit 200w or so for each card with heavy clocks. I'd be only worried if you intended to fold with that rig.

He should be able to do whatever he wants with it. 2x 460s and a 2500K will never pull near 650W at load, OC'd or not.

For your current setup. 650W PSU will be enough if your not thinking of upgrading in the near future.

If you're thinking of an upgrade especially on the GPU side (happened to me), then get a decent (gold preferred) 850w PSU then you'll be good.
