Need a PSU for a new build. Unsure about a few things.

post #1 of 20
Thread Starter 
Hey guys, I am in the process of buying PC parts, and now I need to decide on a PSU.

My system will be a:
Intel 2500k overclocked
6950 hopefully unlocked and overclocked (and I want to go crossfire later down on the road)
1tb Samsung F3
Crucial M4 SSD
DVD drive
8 gigs of ram overclocked


I was wondering what wattage I should be going for? I was thinking maybe 650w, but will it be able to support crossfire?

I don't really want to spend that much on a PSU, so I would like to try to keep it at $100 and below.

I was looking at the XFX 650w, which can be had for $89, and $69 after rebate.
Link
Is it any good? I heard many complaints about XFX, and I saw some people reporting that this PSU has a "clicking" sound. I'm kinda scared.

Any other PSU I should be looking at? Being modular is nice, but I guess isn't necessary. I would just have to work harder at cable management.tongue.gif

Yes a 650W PSU would be enough even for CrossFire..

A single HD6950 in games uses ~120W CLICK HERE (in Crysis 2 Average= 121W and Peak= 132W)


Even with a eventual "unlock" and OC still 650W would be enough (that XFX PSU is OK)..


CHEERS..

650 will do the trick..pick cheapest one listed here or just go with the XFX unit you linked if it tickles your fancy because it is also dandy.

Well, cheapest would be the XFX then.

Still worried about XFX themselves and this "clicking issue". Should I just not worry?

One more question. Whats the difference about the XFX I posted earlier, and this one. Link

Seems hit or miss with the clicking issue..I am sure they would RMA it if it has the issue however.

There are other viable alternatives..if it's in your price range you could always try a different unit..if price is the bottom line grab this one and just RMA if there's any issue smile.gif
