Graphics Card Power Requirement

Hi all,

I am currently thinking about buying a new video/graphics card for my PC, however I'm scared to upgrade due to recent research on my PSU. Don't go crazy when you hear this, but I'm looking for a CHEAP PSU that is reliable and is a great performer. I don't want to do any overclocking just yet, just keep that in mind. I'm looking into buying an ATI HD 7850 by XFX, the black edition to be specific. My 500w PSU by Aywun just isn't there with the 12v amperage, and i'll need 2x 6 pin pci-e plugs to power the thing. I only have one and i don't want to use a dodgy 4 pin molex adapter. I desperately want this card, but what are some recommended budget friendly PSU's that will run it without any problems?

I currently run a Intel Core 2 Quad (Q9450 non-overclocked 2.66ghz) and 8gb of DDR 2 800mhz ram. current card is only a HD 4670 512mb by PowerColor.

The main problem is that I'm In Australia and all the decent cheap PSU's are overseas. Newegg has promising prices but dont ship to AU, so keep that in mind.

I appreciate all responses, thanks! :)

  1. I'd suggest Corsair CX 430. It's cheap and is one of the best 80 plus rated quality power supplies at that wattage.

    Quote:
    500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended
    600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology.


    If you have access to XFX, then I'd get an XFX Black Edition or Core Edition PSU. Avoid "builder" line PSU's like the Antec Basiq.

    Ya didn't give us any web sites to choose from, and I know newegg doesn't ship down under, but at least ya can see the product

  4. Thanks for your responses. I have been looking into the corsair PSU's, but the price was a little to high for the time being. The CX series however is pretty well priced, so I may be going in that direction. The TX series are pretty cool, the prices are a bit higher but still worth considering. The XFX PSU's are quite expensive and I haven't seen one yet that is price friendly, but i'll have another look. Thanks again for your answers.
  5. I've had a look at that season M12 II 520 PSU and it looks great. It's a also modular which I didn't expect. For that price I've got to say that it is a great deal. I'm still a little confused about the amperage of the PSU though as lots of people say that you need great amperage of 30 or so and upwards. Will this be a problem in any way?
