Oops - 550w PSU enough for Phenom II 955?

Will this PSU be up to the job? Not planning on x-fire or anything fancy. Not planning on over clocking in the near future. Or should I order something bigger?


Coolermaster eXtreme Power Plus 550w PSU with 1x PCI-E and 3x SATA

AMD Phenom II X4 955 Black Edition 3.2 GHz

Only 1 HDD

Gigabyte ATI Radeon HD 4870 1GB

Damn - thank you! You've saved my Saturday!

Going to double check now that I've made one n00b mistake ... will this do the trick?
(If it matters my case is a Coolermaster Centurion 5.)

Ok ... I'm assuming there won't be any issue with over-specing the PSU though? The one I posted has excellent reviews and a good price.

Alternately this looks like it'll do the job?

I checked the Gigabyte site for compatibility and it's on the list.

I'm not sure about the Centurion 5 being the same as the 590 - had a quick google for it and they seem to be different?

Don't use cheap off-brand PSUs, no matter what the wattage. Stick to Corsair, and for a single 4870 a 550VX would be enough:

Since you have a crossfire board, how about you leave the option open to add a SECOND 4870?

PC P&C 750W
This is enough for two 4870s

It's also a very high quality PSU.
Well, you might not get that kind of price over there. The Corsair 750TX would be equivalent.


This would be your AM3/DDR3 choice if you wanted to go that way:

It's big enough but not well cooled.
