Third, the recommended specs for video cards are mostly overdone, so that even the worst low cost psu with the given (paper) rating could handle them.
Forth, the recommended PSU brands (OCZ, Corsair and Cooler Master) don't even build psus at all, just rebranding them.
Corsair for example are just OEM seasonic (which itself is top notch, but the oem versions may vary) or channel well.

Fifth, even the idea that a PSU can do ANYTHING to performance is.. borderline to say it the least offending way. |
Finally someone who talks sense, i was amazed at what silly things some people were saying here, and actually others believing them.
Look here, this is an excellent article from a reputed hw site:
Debunking Power Supply Myths. For those lacking time or patience, just read this:

System 3:
Intel Core 2 Extreme QX6850, 4GB Memory, NVIDIA 780i Chipset, NVIDIA GeForce 8800 Ultra SLI, an optical drive, and four hard drives. For our third example, we chose some of the most demanding products for testing. In particular, the 780i Chipset from NVIDIA has the highest power consumption of all chipsets we've tested so far, drawing a constant 69W. (There is of course some variation in power consumption even from chips of the same family, and the features and extra chips on each motherboard differ from manufacturer to manufacturer. Our particular 780i is an EVGA motherboard.) The idle power consumption for this setup is around 310W, and
once we place of full load on everything power consumption increases to 544W.
++++++++++++++++++++++
Grated it's an older article and therefor older components, however please note that this 3rd system is still a monster in power consumption terms and still comes shy of the 550W mark (that doesn't mean that a 550W source is recommended of course).
If anything nowadays the tedency in PSUs usage is gross oversizing, which leads to efficiency loss. And money loss. But hey, go ahead, use 10 PSUs if that's how smart you are, i'm sure you're going to notice vast improvement.
