Hi guys,

i am kind of rookie over here but i bought a new pc and the only thing i am missing is a good psu.

here are my parts :

CPU : i7-3930k (requires 130W)

CPU Cooler : Nocuta NH-L12

Motherboard : Intel Desktop Board DX79SI

Graphic Card : Gigabyte AMD radeon HD 7950 3GB (requires 500W)

HDD : WD 1 TB Caviar Black ( I will add in the 2-3 months another ssd probably).

Case : CoolerMaster 690 II

The pc will be used primarily for playing games @ Full HD , programming , image processing and little bit of virtual machines.
No overclocking is planned for the pc.

What kind of PSU should I buy?
Is this one is good enough?

Seasonic M12II-750 Bronze 750W

For a single 7950 you need 210W . So adding the other components a 550 W will suffice you.

XFX Core Pro 550 W is enough . BUT if you plan to CF down the road you need to get (360W CF) XFX Core Pro 650W (now for 10$ more you get the 750W so why not).

Good Luck !

Well, my local store doesn't have any XFX psu's.

everyone recommends Seasonic.

so which one is more suitable for the long run?

Seasonic Bronze M12II-620W or Seasonic Bronze M12II-750W(their price difference is appx. 35$).

I'd just get the 620 W then since it's a bit cheaper unless you plan on adding a second 7950 in which case then you should get the 750 W.

620 is more than enough. 2 7950 need 360 W so you will be safe . Pick it

Good Luck !

I know 620 Watts are enough power for two 7950's but that PSU only has 2 PCI-E connectors while the 750 Watt model has 4 PCI-E connectors.

If I wouldn't use an adapter, I don't recommend it. And guess what I'd never use one of those adapters to try and save a bit of money.

Would you honestly do that in your build?

Seasonic M12II-750 Bronze 750W gets my vote is it more then you need yes so what i am pretty sick of people ranting on about psus that are more then required if your on a tight budget different story if you can afford Seasonic M12II-750 get it end of story! 550 W is enough so if your on a budget get the Seasonic Bronze M12II-620W

Yes i would. I did in fact in my last build (friend one) Gtx 460 and still its running like a best. I think it was a corsair PSU (if im not wrong and had only 1 PCI and i used the adaptor that came with the card
