i know alot of you out there are going to disagree, but its true, since i am running one of these....http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=924829&CatId=7005
with a 350 watt power supply that came with a emachines computer. its been running for almost a year and a half, with no problems, although the emachins power supply has 2 x 12v rails with 14a on one and 15a on the other. (the power supply the OP has currently is not worth risking though since the amperage is so low) this card isnt bad as far as performance for a low to mid level gaming computer....just wanted to let the op know that if he isnt going for a hard core or even high end gaming machine upgrade, then he dont need to spend $50+ on a power supply. a corsair 430 watt, or even a cooler master or antec power supply for around $35 would work just fine with anything up to say a gtx 550ti, since that card only pulls a max of 115 watts.
