I've got a stock Gateway Performance 933 which uses a 200w power supply.I plan on purchasing an MSI G4 Ti4600 card and would like to upgrade my power supply to 350w using an Enermax brand.Two different 350w Enermax units are litsed on Pricewatch,EG365P-VE & EG365P-VE(FM).Whats the difference in the two and which one should I get for my Gateway comp.?

Thanks StormBringer,
Are these diffacult to install? How?

Code, the GW case wont accpet an "aftermarket" PSU. You are going to have to buy a case while your at it. Also, get the next PSU up from the 365. I think its 431w. I have it and it is very stable.

BTW, I work for GW so I see this all the time.
