Gateway 4300-15e 300w psu upgrading for ATI 5750 HD?

Will I need a new power supply or is it just recommended that I do? If so, which supply would be recommended for my computer. Here are the specs.

AMD Phenom(tm) X4 810 2.6GHz
8GB RAM DDR2
FSP ATX-300GU - 300 Watt ATX Power Supply
Mother board Systemboard with AMD® 780G Chipset
DVD-RW
1TB Hard Drive

Some of it may not be important but there it is.

  1. Is it this one?

    http://www.newegg.com/product/product.aspx?Item=N82E16817104988

    The total wattage is good but it has only 152W on the 12V rail, where are you buying your new PSU from, give us a link.
  2. I have a gateway fx series computer that i had to upgrade to a new video card. Here were my specs

    Intel Q6600 2.4ghz
    3GB DDR2
    G33 Intel Motherboard
    IDE DVDRW drive dug up from somewhere at gateway
    500GB HD
    400W Power Supply

    I recently needed to upgrade my video card as my old 8800GT died. I upgraded to a Diablotek 450W p/s and an ATI 5770 card.

    Running the 5750 on a 300 wouldn't work. It would tax your power supply too much for requirements. Companies put the cheapest power supplies they can into systems to run the components they ship with.
    As long as you don't buy the cheapest power supply out there I wouldn't worry about the brand. If you can find one with 80% or better efficiency for a good price you should be fine. But if you're already looking at Newegg, check the reviews.

    Sorry, I mean to look for a 450W or better, it can probably run on a 400, but the cost is so minimal if you need to upgrade anyways.
  3. Kevin - Does your system have a video card or are you using the motherboard built-in graphics?

    popaholic - Here are the official ATI recommended power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:


    450 watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended.

    600 watt or greater power supply with two 75 watt, 6-pin PCI Express® connectors for ATI CrossFireX™ technology in dual mode.


    The recommendations are for an entire pc system.
  4. First off if you didnt already buy the 5750 dont get it get the 5770.

    450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

    The 5750 and 5770 will run fine on a quality 400 watt PSY with 30 Amps on the 12 volt rail.


    Corsair 450 watt $59.99 after rebate.
