PSU for overclocked 7970 - 150 MM in Length

Hi All,

I have begun purchasing the parts for this build

Planned Build -
CPU - Intel Core i5-3570K 3.4GHz Quad-Core Processor
Motherboard - ASRock Z77E-ITX
Memory - Samsung 8GB DDR3-1600
Storage – Samsung 840 Pro 128gb SSD
Storage - Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Video Card – AMD HD 7970
Case - BitFenix Prodigy (Black) Mini ITX Tower Case

The power supply I had in mind, microcenter didn't have. Thus I am looking for a new one that can power an overclocked 7970 and is 150 mm or less in length, due to my case.

Now, I had the SeaSonic M12II 620 Bronze 620W ATX12V V2.3 in mind, since it confirms to the length. Will I have issues with this. I tried that suggested online program to figure out the appropriate power and this seems to be ok, but I would rather have a second set of eyes before I pull the trigger on this.

    the SeaSonic M12II 620 is an excellent PSU and will provide enough to overclock both the cpu and 7970 without any problems.

    btw, that case will fit ANY PSU . . i don't understand your worry about that.
  2. Thanks for the info.

    Well, apparently BitFenix recommends a 150mm. I was reading about a build that wouldn't allow a 160mm that was modular, which I wanted. Only a non-modular 160mm would work.
  3. well my bad, hadn't used a 6" PSU . . . but there is always the "case modding" option, got a grinder? :lol:
