How much power (power supply) will I need for these new PC parts?

07 Mar

These are the components I will be using:
Ultra X-Wind Copper Fan 2200rpm K8/AM2

MSI DKA790GX AMD790GX Socket AM2+

AMD Phenom 9950 Black Edition (125w)

Kingston Dual Channel HyperX 2048MB PC6400 DDR2 800MHz LL Memory (2 x 1024MB)

HIS Hightech H467QT512P Radeon HD 4670 IceQ Turbo 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card – Retail ***(planning on running crossfire soon to play LotRO Mines of Moria….will it work fine in single set up or is crossfire needed for this game?)***

1 250 HDD

1 DVD/CD drive

Right now I believe I have a 430 watt power supply or something….can I use this power supply for the new set up??? Thanks for any kind of info you might have for me.

    Most parts don’t have a big drain on the power supply. The major exception is the video card (especially higher-end ones like the one you’re planning on using).

    According to ATI’s specs for that card, you need a minimum of a 400 watt power supply (550 if you use CrossFire): http://ati.amd.com/products/Radeonhd4600/requirements.html

    And you shouldn’t need CrossFire for LotRO, honestly. The card itself may end up being a bit of overkill, but at least it won’t struggle.
