Good enough to OC 8350 and CrossFire 7870XT?

post #1 of 13
Thread Starter 
Hey guys,

Just wanted to ask if this PSU was enough to run crossfire and overclock my CPU.

http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139020

I live in Canada and my local PC parts store sell it for 85$. I know it's not recommended to go cheap on a PSU, but if you have any recommendation for something that won't break my wallet, you're more than welcome!

Thank you

My guess is 650w is a little low. It probably depends on your overclock and if you would overclock the 7870XT's as well.

Yes I do overclock the GPU as well... So 750 would be more recommended? Problem is I can't afford a 200$ PSU at the moment so I was looking for something around 100$ more or less...

What is wrong with that PSU? It is great, you need nothing fancy, it's just spending money on nonsense. You will be fine with 650W. 7870 is power-efficient card. I would need 750W for 580 sli, but you don't

I had heard 7870 XT's were much closer to 7950's at peak power consumption. I had to make some guesses to the rest of the system but PSUCalc was giving me results over >650w. You could be right, he might be fine with 650w.

Yes, 650w is plenty.

That PSU can easily run that set up even a quality 550w would work with no issues

Update: I ended up getting a Cooler Master GX 750W. I kept the warranty papers since I heard mixed review but a close friend of mine had the Corsair and switched to this one and he's very satisfied. Time will tell if it's the same for me. One thing I did notice however is that it is much quieter than my old OCZ Fatal1ty... Thank you for all the advice. I also figured 750W would leave me a little more headroom... I do have 2 optical drives and 3 hard drives in there so...
