Ok I have a 300W power supply in my computer, I am running dvd-rw, memory card reader, 2xIDE hard drives, a msi ms-7145 micro atx board, and factory fans. I am getting a bfg GeForce 7600GT 256MB 128-bit GDDR3 PCI Express x16 Video Card, and it says it suggests a 350W power supply will mine be able to handle this or do I need to upgrade to more power? If it matters the most intense game I play is Guild wars....no fps games.

Hi lemans81,

Welcome to PCHF.

Wow thats awesome....it says 252W with everything I have + the card.

Just fyi the card does NOT have a seperate power connector, it just runs off the x16

Nice one lem,

Also a good idea to add about 50w for future upgrades and capacitor aging.

Marked as answered.

I also just to add I found out if I remove the second hard drive...which I rarely use I can subtract about 15W off that number.
