Hi, I need a new PSU for my pc:
core 2 quad q8300
4gigs of ram
640gb 7200rpm sats hdd What Exact PSU do recommend(I am getting a nvidia geforce gt 240 1gb gddr5?
Anyway here are some pics of inside my pc:
The minimum recommended power supply for your entire system with that card is 300W. You have to think about if you're ever going to have more than one card in a SLi setup. If so you'd be better off getting a higher output PSU now. If not then a good solid 400W PSU will be more than enough. Something like a Corsair CX400 or even an Antec Earthwatts 380W would do the job nicely.
Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and the Antec TruePower New series which are major improvements over Antec’s older psu’s like the Basiq models.
If you are only going to use one video card, then the Corsair CX400 would be an appropriate choice. The Antec Earthwatts 380 would be an appropriate alternative.
