Im in the market for a new graphics card, but need to upgrade power supply first. I have an HP p7 1210 and the processor has been upgraded to an AMD a8 3850. I cannot find anyone to tell me what power supplies will be compatible for this computer. SO far the only one ive found thats even close is the p7 1050. Any help would be greatly appreciated. If it helps at all, the memory has been upgraded from 6 to 8 and its a 64 bit system. Also if anyone can recommend a good graphics card for 200 or less that would be the cherry on top. But my main need is not wasting time ordering and waiting for a power supply that isnt compatible. I mainly play The Sims 3 and have all of the expansion packs installed. It runs like a turtle on even medium graphic settings and freezes up constantly so i definitely need some dedicated graphics. Thanks for any help in advance. Also the current supply is 300 watts. I am looking for at lest 400. Preferably 500.
