Is this a symptom of not enough power? Or is there something else I should be looking into?
I just bought this PSU as Phaedrus
suggested a 750w be enough for SLI 580s so I took it a step further and picked up the HX-850 at Microcenter.
BTW does anyone know what the return policy is on PSU's and GFX cards? Exchange only if faulty? Or restock fee?
To be honest, I haven't been able to even complete 3DMark 11 reliably at all. Ever since the 270 family of drivers have become available, the last test always hangs for me and even goes to a black screen that requires me to end the task, regardless if I run at completely stock settings or running rock solid overclocks (validated by everything else). That's why I don't put much stock in running any of Futuremark's benchmarks.
Since it is a brand new unit, if the PSU wasn't able to keep up, your computer would either fully reboot or shut itself off. It's possible, but highly unlikely that your PSU would cause the black screens though. So you should be good to go with your current setup.
As far as MC's return policies, they state them on the back of the receipts. From what I remember, it's usually big ticket items like TV's, laptops, desktop computers, etc. that have specific return limitations. Everything else fits under the 30 day, full refund umbrella. Afterwards, your video card and PSU, if returned, would just be resold as those open box items you see floating around the rear shelves.
