I bought an EVGA GTX 260 over the weekend, and ever since I installed it my system has grinded to a hault. The hard drive spools down for several minutes at a time, my optical drive has difficulty reading discs, and just general lethargic behavior. The box on the card said it required a minimum of 500 watt power supply, so I thought I was ok with the Antec 550w that I bought. Do these symptoms sound like a PS problem, or could the card just be faulty? Putting my old EVGA 7950 GT KO back in my system seems to solve my problems, so it has to be one of the other. My system specs are:
Asus P5N-E SLI
2.4ghz E6600 Core 2 duo
4gb Mushkin DDR2 800
1 western digital 75gb raptor
1 plextor SATA DVD-RW drive
Antec Neo HE550 550w PS (http://www.antec.com/Believe_it/product.php?id=NTU=)
the 3-4 fans that came with my antec nine hundred case
and of course, the GTX 260 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130370)
