PC newb here in need of help.

Alright lets say I have A 300 WAT PSU. and I get a video card that that say "needs a 300 WattPSU" Will that be enough to power my whole PC along with the video card?

Thank you all for your time.

Basically no. You need something that is higher than the recommended amount to give yourself headroom. Duckman5

Gotcha. Thanks a lot. I think you just saved me a headache.

well the answer is yes in the sense that if they state a 300w powersupply is recommended they do mean 300w for the whole system including the gpu, not just the gpu by itself, so a 300w power supply should suffice (if it's a good quality psu that is, cheaper brands don't always supply the power they promise). i would never blindly follow those recommendations though; if you want to know what kind of power supply you should get i would recommend you just post your specs (300w would seem really low for a decent gaming system btw) or you can get a general idea with a power supply calculator such as provided here.

If it is the recommended wattage requirement put forth by the company then of course it would work as long as the Power supply also meets the 12V rail requirements.
