(adsbygoogle = window.adsbygoogle || []).push({}); I'm thinking of getting a new card, a nvidia geforce gtx 275. It says it's min power input is 550w, and i currently have a 550w PSU.

I'm guessing I will need to get an upgrade?

You can get away with it.

It would be safer to do an upgrade though, you can get a 650W.

But if you are willing to spend, get a Corsair HX 850W PSU for the future, and any upgrades that you need.

I have that power supply, and it's great. The Corsair HX models are modular, so all the cables aren't hard wired to the PSU, only the ones you need.

Cheers man I'll look into it
