I got that very same Rosewill PSU. I must say I'm impressed! It ran 3 5830s and 8800gt and Athlon II x4 640 all overclocked almost 24/7 at full load for months without a problem. However, there is no way it can push those 4 GPUs with i7, thats a fact. 1200w sounds about right. Good mining rig tho wink.gif

I believe its mostly the fans and lights. Plus the Rosewill has 5 years vs 3 years of warranty.

Looking at the reviews the CM fan is real loud under load.

I assume you'll be treating them as workstation cards? Rendering and crunching 24/7. Scaling won't come into effect then, so full draw across all cards. HCP-1200 tongue.gif What first came to mind. Or a TPQ-1200. Internally, they are still some of the best.

As far as your current unit goes, it's a pretty average Sirtec made unit and even though it might cope with the load, I wouldn't advise using that power supply for a mining rig like the one you listed.
In regard to the actual power draw of the cards you listed while mining look below:
7970 ~ 220W
6950 ~ 200W
5970 ~ 350W
5870 ~ 200W
^that at stock, for overclocked cards add an average of ~30W per card.

Going by those numbers you will be ~ 1100w on the gpu's alone with overclock on them. Add ~170w for a overclocked 2600k + 150w for the rest of the system depending on the number of fans, etc. That adds up to ~ 1420w Total. That beeing said that is 100% load on all the gpu's and Cpu.

I forgot to mention I'm running a Phenom II X4 830 stock on the mobo as well as an ocz 100GB LE SSD

Ok, that has a TDP of 95w so you will still be in the mid 1300's

He's not using the cards on a SandyB rig, he's using them on a AM3+ platform(mining rig) with a low end CPU(most likely).. and your calculation is also wrong... the 2600K is a ~100W CPU at <1.3v and ~120W CPU at ~1.4v(we're talking about actual loads here not suicide runs @ 1.6v), while the rest of the system might sum up to ~50W, nowhere close to 150W.
