Not such a good couple of months ....
First to die was a PC P&C 1k SR...no power good signal???
Then Coolermaster 900 UCP .....Plug in tester and standby power only
Today Coolermaster 1100 UCP ....Connect to mains and breaker trips (so 3 rigs off all day) This one might be under warranty...hopes
Had to remove a GPU to be sure but replaced with a zippy emacs 510w that I picked up for £1.00 + postage took me an hour to find enough adaptors to power the HD and graphics
