I don't want to dissuade you from mining but you should be aware that profit in GPU mining is razor thin right now.  If you want to do it as a learning experiment or hobby then go ahead.

The X11/X13 algos use less energy than Scrypt but a basic PC with a 280X will still put out close to 300W of heat into the room continuously.

If you live in some place like WA state with 0.02/KWh electricity you can definitely make a nice profit.  If you're paying more than $0.10 you will actually be loosing money if you don't chase those pump/dump schemes.

Well it is an easy calculation actually, find out the maximum wattage that your R9 280X is going to pull (should be found in the techsheet), add it to the wattage all the other components in your PC will pull, add another 100 watt as buffer and the result will be the wattage of the PSU that you should aim for. As far as PSU manufacturers go I made good experiences with Enermax, Thermaltake and Sharkoon PSUs.

On a sidenote though: To my knowledge all the algorithm will run your GPU hot if you let them. It's more a matter of the mining software settings than the algorithm. Which brings me to warning you that you probably should  not mine SHA 256 or SCRYPT coins as ASICs have taken over for both algos making GPU mining unprofitable. So you might want to look into X11 algorithm coins.

If you haven't actually bought any parts for the rig and plan to use it just for mining I'd suggest taking the money and investing it into a decent ASIC machine.

I have decided to build a rig and get involved in the mining side of things. I have no interest in mining hot algorithms this time of year. I have settled on R9 280X for my GPU. I do not know how much power 4 of the R9 280X will require under full load. What does everyone else use and what would be suggested? Thanks in advance for any assistance.
