  1. Yes it will be more than enough for your GPU.
  2. thanks you and fast replied! :D

    but i have installed the GPU with the old PSU. seem okay. no problem at all . or i need remove the GPU back???
  3. If it's working okay you don't have to, but the problem is that it might cause problems when the system in full load. If your PSU can deliver at least 300W, you don't have to think about upgrading.
  4. whats the model number on your old psu? you might be able to use that. Not sure what the difference btwn pure power and max power is...
  5. thanks you @ilysaml and @slicedtoad .

    i think the model PSU is Magnum 250.

    urm.. i should change the PSU! :D
  6. Very wierd psu documentation.

    Anyway it has 18A 12v rail so it should be fine. GPU + CPU should only need around 155W at load. It's not exactly quality but i'd wait till it dies before upgrading.

    If you do upgrade don't get the cm one you mentioned, get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033
    It's a very good psu and cheap.

    If you want something that looks nicer tell me.

    You should change the PSU for the quality not for the output, as your system can run in a 250W PSU including the HD 6670.
    I suggest you do that move when you upgrade your whole system.
  8. As slicedtoad said, you don't want the CM PSU. A low-end Antec or Seasonic would be fine.
  9. but he doesn't have to upgrade at this point.
  10. okay. i take advice from you guys . but my old PSU support to my LCD monitor too ..
  11. for now, i just try to play some game like crysis . and no lag with high setting but when i play so fast . the lag happen little bit .
  12. your psu supplies your monitor? I really don't think so. Your monitor should be plugged into the wall or a power bar. There are no compatibility issues between psus and monitors.
  13. this is my PSU look like .

    me put 2 cable at the PSU . one cable i plugged it to the wall . and second i plugged to my monitor.
  14. riighht. I have no advice on that psu.

    Pretty sure that's just a pass-through. It's not actually powering your monitor, it's just giving you an additional plug.
  16. Slicedtoad . sorry make u confuse at the first conversation . but, can i upgrade that old PSU with the one u recommended to me ?
  17. oh . i see . thanks for ur support . :D
  18. yeah you could upgrade it to a earthwatts 380 but i wouldn't unless your old one give you problems.
