Power Supply Question

post #1 of 11
Thread Starter 
Hey Guys,

Im hoping a 750w PSU will run this build, its mainly the Graphic cards Im worried about.

2600k @ 5.0
Crossfire 2GB ASUS ATI 6950s (Unlocked to 6970)
P67A-UD5 Motherboard
8GB 1600 RAM
1TB HDD
60GB SSD (In the future)
H60 Watercooling
Wireless card

Im hoping this http://www.overclockers.co.uk/showpr...odid=CA-233-CM will cover the build.. If not. Ill be forking out a lot on a 850w

Thanks in advance,
Shox

Hmm, here's JG's review of the PSU: http://www.jonnyguru.com/modules.php...tory5&reid=188

It's not that great. I would go for a quality 750W, like the Seasonic X-750 if your budget allows. I'm running a 6970 and 5870 off it.

I'd personally go with Antec or Corsair for the PSU as I have not had any problems with Antec and my friend has not had any problems with his Corsair 750w PSU.
http://www.jonnyguru.com has reviews for PSU's.

I second that.

A good 750w could run that, but the one you linked might not be able to.
If stressed, the PSU would probably shut down/overheat.

As long as you don't stress everything in the system at once to peak performance, you'll be fine until you can get a better PSU. It can output around 650w with lower efficiency (less than 80%) and will rise above 40c, but should still hold together. Assuming each card uses around 200w, the rest of the system won't use much more than around 200w total at full load. It'll be safe to use this PSU, but a better one is the best option.

A good 750W can run that very well.
post #10 of 11
850W can run a Tri-fire 6950, again quality is everything =D

And power consumed by 6950's can vary a fair bit with powertune +20% and various fan setups.
