Upgrading comp, looking for a power supply?

Hello everyone!

My computer specs are:

Windows 7 Home Premium 64-Bit
AMD Athlon II X4 645 Processor ~ 3.1GHz
6GB RAM

Now.. I'm going to be upgrading my Graphics Card to the Radeon HD 6770.
What Power Supply would work well with that graphics card and my processor?

Thanks!

    CX430V2 will power your system easily.
  2. 450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for AMD CrossFireX™ technology in dual mode).

    ^ That's what it says for the 6770, so would the CX430 really work? ._.
  3. Yes because the system is only going to pull less than 300watts under load http://www.anandtech.com/show/4260/amds-radeon-hd-6790-coming-up-short-at-150/14 The manufacturers recommendation is high because of all the crappy PSU's on the market.
