Hey, new to posting here but have read a good amount. I just ordered a Phenom II X4 980 Black Edition Deneb 3.7GHz which says it requires 125 wats. I am also using and hd radeon 6850 2gb and 5 gigs of ddr3 ram.

So without thinking I ordered it and am now realizing im still using my older PSU which is a cool master 550w power supply.
I'm currently using an amd athlon x2 220 2.8 ghz processor and it runs solid. However would it be able to even run with this new CPU?

If not I was looking at this one http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Any advice?

Thanks

I'm running my system using a Corsair 650W and the most it pulls when I have something like MW3 running at high is ~270 watts. I would personally try to use your current 550W PSU and see if it powers up and then decide what to do from there if it doesn't work.

Are sure that 6850 has 2GB of memory?

With 550W you will be fine.

Alright, I'll try it out when it gets here and go from there. Just wanted to make sure it wouldnt be a bad idea to even try. :o

I'm sorry that was a typo. It has 1GB of memory.

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

You didn't specify your Cooler Master PSU's model but as you can see below they are all capable of powering your system with a single Radeon HD 6850.

Cooler Master GX-550W (RS-550-ACAA-D3)
• a +12 Volt continuous current rating of 44 Amps
• two 6+2 Pin PCI Express power connectors

Cooler Master Real Power Pro 550W (RS-550-ACAA-A1)
• a combined +12 Volt continuous current rating of 36 Amps
• two 6 Pin PCI Express power connectors

Cooler Master eXtreme Power Plus 550W (RS-550-PCAR-E3)
• a combined +12 Volt continuous current rating of 30 Amps
• two 6+2 Pin PCI Express power connectors
