Hi , i'm going to build a pc soon and the only thing that is left to choose is the PSU .

I'll be having a i5-3570k , 1 DVD-Burner , 1 SSD ( and an HDD later ) and a Sapphire HD 6950 2GB.

I was thinking about a OCZ 600w Modular , Corsair CX600 or Corsair GS600 . What can't spend to much so , what do u think ? Thanks for your time :)

Hey,

There are many good brands for psu's like corsair, antec, seasonic, ocz to name a few. I would say if you can than go for the corsair tx650w v2. I ran some calculations and your system would draw under 400 watts max. under load (I factored in the HDD as you mentioned getting one later). So you will be more than fine with 650watts, and corsair makes some great units, i use a tx750 (v1) and I am very satisfied. I haven't used their second generation (v2) of the tx series but from what i've seen its pretty good. The tx650 v2 has got 53amps on the 12v rail so thats 636 watts, and that is more than enough for what you need. Some people say they can be a bit noisy though. The tx650 v2 is made by seasonic for corsair and they make good power supplies. Newegg has it for $89.99 right now.

Hope this helps!

Another option could be the SeaSonic M12II 620, it has received good reviews on newegg. Seasonic is the same company that makes the tx650v2. This one is an older design than the tx650v2 but it is a modular psu, so you can detach the cables you dont need.

it also is $89, but i think that the corsair is better tho, as it is newer. Or you could look into other brands. The Gs600 as others have mentioned is pretty good, but the tx ones are better quality. It costs the same $89 (on newegg) as the tx650v2, and is better.

Only 400w ? So , if I get the TX650 v2 will I be able to Crossfire 2 HD 6950's in the future ?

the "problem" with the 650TX is that it has only TWO 6 in pci connections; meaning you will have to use 2 of those horrible molex to pci power dongles to crossfire.

this is just a few bucks more and has 4 pci power connections - a little overkill on total wattage though . . .
Antec High Current Gamer Series HCG-750 750W $94.99
$79.99 after mail-in rebate

it is not about the wattage you need for that set up as much as the power connections . . .
Radeon HD 6950 CrossfireX review
Measured power consumption

System in IDLE = 184W
System Wattage with GPU in FULL Stress = 473W
Difference (GPU load) = 289W
Add average IDLE wattage ~ 40W
Subjective obtained GPU power consumption = ~ 329 Watts


even the antec BP550 would handle that . .but MY PERSONAL preference is to stay away from those molex to pci power dongles.

For me it's 72€ , so for the same price i can go with the CX600 or the GS600 for more 10€ .

I was thinking about the TX650M , what do u think ?

sorry i missed that you are on the other side of the pond . .

if you want to Xfire two 6950s i so recommend what i posted before:
Antec HCG-750 High Current Gamer 750W Power Supply £89.70 Inc VAT

the TX650 has 2 six pin PCI power connections this has 4. now IF you don't mind using 2 molex to pci power dongles, then the TX650 is fine.
