Is 500w acceptable for this setup?

Forgive my ignorance here, as I'm not very well versed on computers in general.

This is the exact rig I'll be using plus a discrete 6850.

Will a 500w PSU be acceptable here?

I was looking at this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171031
but I was in the process of trying to find something of better quality at a similarly low price point.

Also, the only reason I went with that setup is because I got the computer for about 350 (and I managed to snag a 6850 very cheaply on ebay, which I'd bought before the computer). Accounting for free shipping, Windows, and the included peripheral components I figured I'd be hard pressed to build something much better for the price and didn't want to bother with building it anyway. I know it's not an ideal setup.

Thanks for any answers/help with the matter.

  1. 500w should do it just fine
  2. I can't see anything wrong with that PSU.
  3. If you paid a small amount extra you could get a more reputable PSU such as:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

    Has a bronze 80+ efficiency rating which is always good.
  4. The problem with pre-built PC's from companies such as HP or Dell...is that the way they design they're PC's is a pain. If you can fit an atx psu then you should be good to go & get a 500W Corsair Builders PSU. They're quite cheap & good build quality.

    Hope I helped mate :)
  5. For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 25 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C-50°C ambient temperature, is the most critical factor.

    The Cooler Master eXtreme Power Plus 500W (RS-500-PCAR-D3-US), with its combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connector, is more than sufficient to power your system configuration with a single Radeon HD 6850.


    I would recommend the following better quality longer warranty PSU. It has exactly the same physical dimensions as your existing HP OEM ATX PSU. It also has a +12 Volt continuous current rating of 32 Amps and with one (6+2)-pin CI Express supplementary power connector.

    CORSAIR Builder Series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply for $45.99 ($25.99 after $20.00 rebate card)

    Hi - 500w is more than sufficient - but I wouldn't get that particular PSU - plz go for a quality unit:
    eXtreme Power Plus 500 Very Poor efficiency. Ripple and Noise above maximum allowed. Hardware Secrets
