I have a basic computer a APU A6-3620 Quadcore 2200 MHz, with a Radeon HD 6530D integrated 512 graphics. Being broke i ordered a gtx 260 for $45 USD. But i only have a 300w PSU and no money to buy a new PSU i checked Cooler Master Power Supply Calculator and it says the minimum PSU should be 294W after felling out the calculator. Can anyone give me advice on this please and thanks.

yeah, that's way to close.

Even the good high quality PSUs are only recommended to use 80% of the Watts the list.
Trying to use 99% of your garbage tier PSU is not gonna work out.

Gtx260 uses up like 182w on it's own. your CPU is using probably 65Ws and your ram, motherboard and HDDs will be using up the rest, probably another 30-40Ws.

yeah, it's old and weak by today's standards, but it still consumes the power it always has.
You will need at a least a 500W psu. because anything lower wattage likely won't have the 2x 6-pin pcie power connectors it requires.
It's also not really a good GPU anyways. Woulda been smarter to keep saving your money.
