Re: Which PSU for this rig?

Wow... okay. Thanks for the warning.

What do you think of this one?

http://www.amazon.co.uk/CoolerMaster-Silent-Pro-M1000-internal/dp/B002SP2FVM/

Its 100W and (I hope) silent.

Could this support five 5870s?

Thanks again for your help.

Miners will be much louder than power supplies. These size fans are virtually silent compared to the 58xx's.
