NVIDIA GTS 250

Ok, I would like to buy this card. It's compatible with my software, it can phisically fit inside my tower. My PC's memory can run it, but I'm not sure if I can power it. I know You need 26 amps on the 12v rails, whatever that means, so how can I tell if I can power the card? Thanks. My PC is an HP Pavillion a6330f PC. I bought it out of store, so it's standard. So if anyone knows the complete requirements for this card, or how I can tell if I can use it with my PC, please tell me. ( I know nothing about computers) Thanks again.

I would recommend getting an HD4770 instead, it performs about the same but uses 30W less power.

Not knowing your case, you would have to measure the space where you would plug in the GTS 250 and see if your case has the room.

I don't have a 4770. I don't know what card you want to get, but their are "good name" HD4770s as well as GTS250s. My point is that with a 4770, which gives the same performance as a GTS250, you would not need to spend extra money on a PSU.
