  1. Don't buy from ebay.
    That isn't a good PSU.
  2. No, it won't be enough. I would advise you to get a cheap, new PSU like Corsair CX430M, right now it's $24.99 at Newegg.
  3. Most Radeon HD 7850 recommend a minimum of a 500 watt power supply. CORSAIR Builder Series CX500 500W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply. This one will work for you along with ones from Seasonic or Antec, stay away from Thermaltake or Coolermaster.

    the psu cost $24 and shipping cost $25 which is a total of $49 I can't afford to pay more than $50
    will it be able to handle the hd 7850.

    Not that one, unless you really want your system to explode in a cloud of smoke. I recommend this -

    XFX core 450W 80+ Bronze Certified PSU - http://www.ebay.com/itm/XFX-ProSeries-Core-Edition-P1450SX2B9-450W-80Plus-Bronze-Active-PFC-Power-Supply-/200709547904?pt=PCA_UPS&hash=item2ebb38a780
  6. Does your Radeon HD 7850 OC Edition require one or two 6-pin PCI Express supplementary power connectors?

    For a system using a single AMD reference design Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector. Some of the non-reference design Radeon HD 7850 graphics cards require at least two 6-pin PCI Express supplementary power connectors.

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

    Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

    The Thermaltake Litepower 450W (TT-450NL2NK) power supply unit, with its maximum combined +12 Volt continuous current rating of 25 Amps and with NO PCI Express supplementary power connectors, is insufficient to properly power your system configuration with a single Radeon HD 7850 graphics card.

    The SHARK TECHNOLOGY 500W (ATX-500) power supply unit, with its maximum combined +12 Volt continuous current rating of 22 Amps and with NO PCI Express supplementary power connectors, is insufficient to properly power your system configuration with a single Radeon HD 7850 graphics card.

    The Corsair CX430M (SKU# 75-002016 / CP-9020058) power supply unit, with its maximum combined +12 Volt continuous current rating of 32 Amps and with one (6+2)-pin PCI Express supplementary power connector, is sufficient to properly power your system configuration with a single Radeon HD 7850 graphics card.
  7. "XFX core 450W 80+ Bronze Certified PSU", I cannot buy it because shipping is not available to my country

    I did not buy the HD 7850 yet I am going to buy it
    Link for the HD 7850 : http://www.ebay.com/itm/Sapphire-Radeon-HD-7850-OC-D5-1GB-Dual-X-Graphics-Card-VGA-PCI-Ex-/261277355886?pt=PCC_Video_TV_Cards&hash=item3cd5580f6e
    I need a psu for the hd 7850 I am buying but I cannot find a psu that is less than $150 with shipping included than those power supply units

    should I buy a different graphic card that need less psu power
    what grapic card would you recommend for playing games in medium settings.
  8. Do you have access to any computer parts vendors locally?

    Hi - what country are you located in? I'm sure we can find a suitable PSU for you.

    I see the card is in S.Korea, is that where you are?

    This should work fine for you:

    http://www.icoda.co.kr/goods/detail.html?num=219916
    or this for less money:
    http://www.icoda.co.kr/goods/detail.html?num=222472

    Both have enough power and both have 2 pcie connectors.
  10. its expensive to buy locally, buying from ebay is cheaper.
    I don't live in S.K,I buy from there because sellers from S.K give free shpping to my country.
    I live in Sri lanka.
    I will collect some money and will buy this
    "Corsair CX500 80Plus Bronze Power" :http://www.ebay.com/itm/Corsair-CX500-80Plus-Bronze-Power-500W-ATX-/261273679503?pt=PCA_UPS&hash=item3cd51ff68f
  11. It's a decent PSU.
