Sometimes generic is just better... it's sad but true. I had this Jetway motherboard with a Phenom II x3 720 OC'ed at 3.8 ghz and it's still running to this day. Knock on wood.

Not everyone is made of money, and buying what comes affordable is only natural. Long as the user gets what they need it for it. But the debate was CX600 vs XFX Pro 550. I still believe hands down even if it's probably 1 12volt rail, it'll run more efficiently for him and his current rig. Where you might require a second 12volt rail specifically for your overclocking or intensive use. Now! This is an important thing to know most lower cost dual 12volt rails do more harm than good, because they are not as steady and clean as a single. I'm sure you know that too? Buying a power supply way above the your rated power consumption can do terrible harm too. It's always best to fit your quota within 40-120 more watts than you use. If he had a 300 watt computer and was using a 1k watt PSU the efficiency would drop significantly. Also a different type of failure would occur. That's too technical, but think like a nuclear plant not getting it's power consumed. Some of the really high wattage PSU have lower power features which is good.

Running that in extreme will clearly tell you if GPU is running properly on full load or not.

The GPU won't underclock itself if the PSU doesn't deliver enough power it will simply BSOD, crash game/application, reboot, etc. A GPU does not "detect" when it isn't receiving enough power, that's not how it works. GPUs throttle today because of the way the drivers are designed, using boost to ramp up clocks. The driver has a power limit and if you reach that, then it will throttle itself. That has nothing to do with the PSU.

Well it could be a faulty GPU as well, have you tried it on another desktop? Since the GPUs will throttle if it draws too much power at one point (Hitting power target)
