I'm building a computer at the moment and I'm having some dilemmas.

Specs:

Gigabyte H67MA UD2H B3
i5 2310 @ 2.9GHz
16GB DDR3 Corsair Vengeance
ASUS HD6850 DCU & MSI R6850

so far..

Now , the main problem is the PSU.

1. The motherboard has a 8 pin connector for the CPU.
2. The graphics cards need one 6 pin connector each
3. The recommend power supply wattage for crossfire is 650w

So with that known, I went searching for a 700w power supply and found this: http://www.thermaltake.com/products-model.aspx?id=C_000...

But it says : Output Capacity 600W / 500W
Max. Output Capacity 700W / 600W

What does this mean?

Yes, but it's a REAL 600W. A lot of less quality psu's overstate their actual power and can't deliver what they promise.

Also it's important to have a psu which is stable, meaning it doesn't have all kind of distortions and ripples.

Ah I see , I am on a budget though so I need a power supply with some bang for buck.

Well, the power supply is pretty much the one place you dont want to skimp. And you do have 2 cards. That 600W is probably the lowest I would go to run that setup.

This might run it:

But I would definitely go for the 600W Corsair. The thing is that is the bang for the puck power supply.

Corsair TX 650 v2. Simple. As an all rounder the TX series can't be beat overall.

You should start your own thread but I wouldn't. You are pushing it and the CX is a budget series. It SHOULD work, but I'd like a little more breathing room.

I wouldn't push it that close with the CX600.

Is there any reason why you're going with two HD 6850s in a new build? That's waste of money...

Well if you have them already, then you may as well use them. If you want to get the power to run the cards, I would look no less than the CX600 I listed. Any cheaper and quality is going to seriously decline.

Not Aywun, you want quality, not throwaway junk.

I quite like Aywun. Has anybody had any problems with them?
