You will know if your PSU can power your GPU when it does or it doesn't. Joey above talking about BIOS and stuff is wrong. BIOS has NO WAY to know how many watts your PSU is capable of pushing and will NOT adjust performance off PSU wattage ratings, that is hogwash. The power supply doesn't even KNOW what wattage it is. Power is drawn until it's not enough and the system fails. If your PC runs on a 500 watt PSU it will until the unit fails. If you calculate your system wattage part by part you will get an accurate total wattage of system. If it's over 500 watts buy a bigger PSU. Don't skimp out on a PSU but don't waste your money because someone told you BIOS will adjust performance in relation to PSU rating. Nonsense.
Sorry, there was a problem. Please try again later.no it is not enough. this is old retail trick from way back and a play on words as well. the system bios and power plan of the computer will simply scale back on the power whenever it sees fit to make the 500w power supply appear to be working for you, but in reality, you are just getting less performance that you paid for with hardware. for example you may have a processor that can use up to 180w and run up 4.9ghz but you will never get there and it may stop at 3.7 ghz to keep the system from crashing. same goes for the video card. it may be able to use up to 170w but if the system doesn't have enough power you may only get to 150w leaving some performance on the table. you may never know any better because it still performs good, just depends on what you are doing.
