Hello,
Im thinking about upgrading my graphics card to a sapphire HD 5670, but im not sure if my PSU will be able to handle it.
My specs are:
CPU: AMD phenom ii x2 500 3.1ghz
Motherboard: Gigabyte MA785gm-US2H
Ram: 2GB DDR2
Running on board graphics:
Radeon HD 4200
PSU: Cooler master elite power 400w

It should work fine with the HD5670

^+1, 5670s work on 300Ws just fine.

Ive done some research and found that my PSU can only go to 350W, but im not sure if thats true

What matters with your PSU is that it has 276 watts available for the dual +12 volt rails which gives 23 amps total and is plenty for the HD5670

It should work, specs wise, HOWEVER, CoolerMasters low end PSUs are not that great quality...

Dont you mean 32 amp total?
16 x 2 = 32

16 x 2 = 32

That would make a total of 384watts but it is not simply adding the rails together. Both rails can supply safely 16 amps independently but they only have 23 amps to play with so if one is at 16 the other one only has 7 left to deliver. There is only 276 watts available for the +12 volts http://www.newegg.com/Product/ImageGallery.aspx?CurImage=17-171-042-TS&SpinSet=17-171-042-RS&ISList=17-171-042-Z01%2c17-171-042-Z02%2c17-171-042-Z03%2c17-171-042-Z04%2c17-171-042-Z05%2c17-171-042-Z06%2c17-171-042-Z07&S7ImageFlag=1&Item=N82E16817171042&Depa=0&WaterMark=1&Description=COOLER%20MASTER%20Elite%20Power%20RS-400-PSAR-J3%20400W%20ATX12V%20v2.31%20%20%20%20Power%20Supply

No, it's Watts total divided by 12 which in your case is 276w and 23a.
