    The GTS 240 doesn't use a ton of power as far as I know, so you might be able to get away with 650 watts. Typically you'd want at least 750 for SLI just to be safe, though. If you blow your PSU, it can damage other components in your computer when it goes, and end up costing a lot more than a replacement PSU.

    My recommendation would be to find a PSU calculator (just google PSU calculator) and find out how much power it says you'll need, then add 100 watts to it to be safe.
  2. it says recomened is just under 400 so ill be ok thanks for the help
