Newbie needing PSU help

So I decided to upgrade my Graphics card for Christmas. I'm only running a 250w PSU though and need to upgrade to run any decent card.

Here are my specs

Type AMD Athlon II X4 630 / 2.8 GHz
Multi-Core Technology Quad-Core
Mainboard
Chipset type AMD 785G
Installed Size 4 GB / 16 GB (max)
Technology DDR3 SDRAM
Memory Specification Compliance PC3-10600
Form Factor DIMM 240-pin
Type 1 x Serial ATA - Integrated
Controller Interface Type Serial ATA-300
Hard Drive 1 x 750 GB - Standard - Serial ATA-300 - 7200 rpm
ATI Radeon HD 4200 Shared video memory (UMA)
250 Watt


I was planning on probably upgrading to the radeon 6670. I don't know much about power supplies, so hopefully someone can point me in the right direction of a good cheap one that will run all that + my 6670.

Also, do you guys think upgrading to the 6670 is a good move?

Budgets around $100. GF gets made when I spend money on the computer, which I'm always on :)

  1. If your system is a consumer desktop unit like an Acer, Compaq, Dell, Gateway, HP, Lenovo, ..., etc., then please provide the brand and model number of the system.

    If the computer case is a small form factor case your power supply choices will be very limited.
  2. HP p6654y
  3. The HP Pavilion p6654y is a mid-size ATX tower and uses a standard ATX form factor power supply unit.

    The following PSU will be more than adequate for powering your system with a single Radeon HD 6670 graphics card:

    Corsair Builder Series CX430 V2 (CMPSU-430CXV2) for $44.99 ($24.99 after mail-in rebate card)

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

    It will even handle a Radeon HD 6770 or Radeon HD 6850 if you want to consider it.
  4. 6670 is a good entry level gaming card. Much better than integrated graphics.
    It needs a pcie-X16 slot and a 400w psu.
  5. Ok so I looked at my old computer, and it has

    Enermax Whisper 431 watt ATX (EG465P-VE/FC)

    Will this work?

    Specs on it are

    +3.3v & +5 : 220W max : Total power = 431W

    For a system using a single Radeon HD 6670 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 22 Amps or greater.

    The Enermax Whisper EG465P-VE(FC), with its +12 Volt continuous current rating of 33 Amps should work fine.
