What PSU do I need?

Recently I asked here if troubles I had sounded PSU-related, and they were confirmed to be. However, I then realised that I wasn't exactly sure what type of PSU I needed - or even what manufacturer would be best.

Here's my setup:

4870 x2 <--- I think this is causing power draw problems atm
SATA2 HDD
solid state HDD
4 usb devices
no other internal cards, although on-board stuff like networking and sound as normal
i7 820 with a stock cooler

What kind of PSU should I be getting for this lot?

    According to the Thermaltake Power Supply Calculator
    (and I assumed you meant i7 920)

    You'd need a 500 - 550 Watt PSU
    Although I'd recommend a nice 600 watt PSU in case you want to chuck in some expansion cards or more drives...

    The computer build thread has a section on PSUs.

    My recommendation would be to go with the Corsair 650W non-modular supply. It should be more than enough to keep you up and running, and it'll give you headroom for the future.

    Hmm, I'm currently using a 750W psu but it doesn't seem to be doing the job. If I switch to a better make but lower wattage does that have a decent chance of stopping the random resets?

    Thinking of going with this.

    What brand is your PSU? it makes a pretty big difference to have a good name-brand vs some no-name crap.

    no-name crap, hence my suspicion of it

    If you're willing to spend the money, the 750HX is a great buy.

    Oh yeah, no-name PSU's will often advertise giving certain wattage and fall really short of delivering it, while having an efficiency of less than 40% and spiking your electricity bill.

    My choice PSUs are:

    Corsair
    Seasonic
    OCZ
    Coolermaster Real Power series
    Antec
    BFG


    Or you could just click here, these guys know what they're talking about.
