Need Suggestions for best Graphic card

Is a 300W PS sufficient to support a Radeon HD 4670 card if it's the only upgrade added to an HP AMD Athlon X4 620/4GB/500GB system w/1 optical drive? HIS, Sapphire, etc., sites indicate 400W is required.

Thanks

  1. Best answer
    The HP psu is a quality unit equal to many other 350-400watt units it should have no problem with the HD4670 here is link to a good deal http://www.newegg.com/Product/Product.aspx?Item=N82E16814121329
    $45 after MIR
  2. I dont know really. But i would get a better PSU.. Here this can maybe help you abit : http://extreme.outervision.com/PSUEngine i tested your's and it said about 460 W would be enough (: hope it helped abit.
  3. The 400w PSUrecommendation is to compensate for really low quality, unbranded overrated PSUs that can be found at any computer store for $15-20. HP used much higher quality PSUs than that. You will be just fine with a 4670 on that system.

  8. I'm not sufficiently familiar with the PSUs that HP uses to answer with certainty, but it would probably be safest to upgrade to a known good PSU. Look for one that has full range active PFC (no little voltage switch) and is at least 80+ certified. Antec, Corsair, PC Power & Cooling, Seasonic, and Enermax are among the better brands.

    Hm! That calculator might be wrong. You buy an HP system it ships with high quality 300Watt psu, you add to it less than a 75watt GPU and the calculator says it should not have been running in the first place.

    Usually HP uses Delta or bestek psu´s a big producers for the server market.
  11. Delta = Good, Bestec = Bad, iirc. "Death of a Gutless Wonder II" at jonnyguru described a Bestec unit such as the ones used by eMachines. Fecal.
