I have a huntkey 550w greenpower, does it really supply 550w or less, I want to add a second Radeon 5770, but that will depend on how much power I have to work with, the psu is rated at 80+ Bronze. Please advise

Current Specs: Amd phenom2 965, 2*2GB Kingston 1333, Radeon 5770 1gb ddr5, 5oogb 1tb and 1.5tb seagate HDD's, std 22* dvd writer, raidmax Quantum case,

Also how do I tell if my processer is c3 stepping or not ie it draws 130w or 140w

Thank you for your support and time

I would consider getting a quality PSU before putting in another HD5770.
A PSU only puts out the power that the components need.

Download and install a program called CPU-Z. It will peek inside your CPU and tell you what your core stepping is.

Here are the official ATI power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:

450 Watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended

600 Watt or greater power supply with two 75 watt, 6-pin PCI Express® power connectors for ATI CrossFireX™ technology in dual mode

The recommendations are for an entire pc system.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty (in the USA).
