Hey guys basically I really want to upgrade my computer for gaming and I really need some opinions before I finally pay.

I have a factory made Acer AM3920 E4142.

Intel i7 2600
Intel HD 2000 Graphics
Intel H67 Express Chipset
1 TB Hard Drive
Windows 7 Home Premium 64-bit

The integrated graphics are really quite terrible so I am deciding to purchase an ASUS Radeon HD 6850 DirectCU 790MHZ 1GB 4.0GHZ GDDR5 2xDVI DisplayPort HDMI PCI-E Video Card.

However, I need to upgrade my PSU as the one in the computer is currently only 300 W. I have been looking around and one that has caught my eye solely based on price is a Coolermaster Extreme Power Plus 500W ATX 12V V2.3 Silent Power Supply 20/24PIN 120MM Fan.

However, would 500 W be enough? Any suggestions for any PSU within a range of 50-100 (Preferably 50-75) would be greatly appreciated.

  1. This should fit the bill:

    PC Power and Cooling Silencer MK III PPCMK3S500 500W ATX12V v2.3 80 PLUS BRONZE Certified Modular Active PFC Power Supply

    Sixty bucks after mail in rebate! It's modular and 80+ Bronze rating. I've heard good things about this brand as well.
  2. Oh I see you're in Canada so disregard my suggestion if you can't use Newegg.
  3. Yeah I checked that model on Canadian websites and the rebate actually ends today for them. Thanks though!

    Any other suggestions would still be greatly appreciated
  4. That system with a HD 6850 would work with a good 500W PSU.

    It just so happens that the CM Extreme Power Plus 500 is a 431watt PSU. (notice the missing W on the 500 part of the label?

    You can find better options at near the same price.
    I'll look around a bit for you.
  5. @ with a $20 rebate and an extra $8 off today and tomorrow.
    CORSAIR Builder Series CX500 V2
    Looks like the total price after rebate, etc, is pretty close to the CM PSU.
  6. @ NCIX with $20 rebate and free shipping.
    OCZ ModXStream Pro 500W semi-modular PSU
  7. these are really great suggestions its just too bad that the promos expire tomorrow. I can't really purchase anything for a week or so, but will keep these in mind.
  8. Stop back in a day or two before you're ready to buy and ask for good deals.
    All you really need to know is how to avoid the few bad apples out there.
