Need those PSU guru's

Hey there everyone,

Just wanted to ask a quick question. My brother is in need of buying a new PSU preferably today. So he is resorting to "best buy" most likely. I know I know... Anywho.

Are the Corsair CX series good units?

Example http://www.bestbuy.com/site/Corsair+-+CX+Series+Modular+CX500M+500W+ATX+Power+Supply+-+Black/8324284.p?id=1218872214065&skuId=8324284

He's only running a 650 gtx, i5 650 (I believe I'd have to go home to look)

But i'm assuming a 500 watt quality psu would be sufficient. Or should we go with the 600w? Reason I'm asking is his machine was a business pc converted gamer pc that ran off of a hp standard 300w psu for a long time. Now he is getting coil whine and some other symptoms that it's going out so I've instructed him not to use it until we can replace it.

Last question. Being that it is a hp model pc. Are the PSU's going to be standard as far as the plugs etc? Or does HP typically monopolize those parts and force you to order from them? What should I check for etc.

Thanks a ton!

  1. alot of people seem to use the builder series psus. i havent used it but it should be decent enough wattage. if the 600 isnt that much more grab that or just order one online the 600 is 49.99 after the rebate and will be the same price even without the rebate after tax http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028


    they should be fairly standard plugs on them. just make sure that the psu will fit in there sometimes they are funky diameters

    The PSU you chose for that GPU/system will be plenty. I've put a couple of those into similar builds for friends without issues.

    I can't comment in regards to the HP case, and whether or not it has a proprietary-fitted PSU.

    I can say if it is, and custom modification is not possible, your best bet would be to move everything into a cheap replacement case, as the OEM manufacturer is unlikely to sell you anything but an exact replacement for the PSU that came with it.
  3. That CX500M should work just fine in the rig.

    As long as the machine is using the ATX form factor and standards, everything should fit and plug in correctly.
  4. What hp model?
  5. dbl post
  6. Awesome!

    I appreciate each and every answer. If it doesn't fit I'll get crafty with the case and chop and slice until I can make it fit ;). I was more worried about the connectors being funky.

    Wished I could put more then 1 best answer but I guess I'll go with a random one.

    Thanks again everyone.

    The HP Elite 7000 MT

    I didn't see a spec for the Proc on there... The gpu that was in it has been removed and replaced with the 650.
  8. Height 3.4 inches
    Width 5.9 inches
    Depth 6.3 inches < This is where the issue will be if you have one , it will be too tight.(Length)

    You should be fine by the pics I've seen online.:D

    Alright awesome.
    Think the 430 watt will be plenty?
    I'm still gonna check the local best buy tonight to see if anything fits the dimensions too. As long as I stick to corsair, xfx, seasonic etc I should be good right?
  11. PCI-Express Connector
    1 x 6+2-Pin

    Yes a 430 will run it ^ A GTX 650 should only need 1 PCIE Express connection and the 430 has one.

    Kk sweet. If I run into any questions I'll post again tonight after work before purchasing. Thanks a bunch!

    I'll make sure to pay attention to the dimensions.
