Are OEM power supplies still bombs? For a while there they were actually putting in pretty good quality PSUs, if a bit under rated and with proprietary ports. 

For the longest time where were absolutely bombs though.

Yeah Dell PSUs are alright, albeit proprietary as you said. But otherwise I generally don't trust PSUs from anyone other than EVGA and Corsair. When I worked at a computer repair shop those two brands were consistently rock solid while most others were hit or miss. OEMs were by far the worst though.

EDIT: I'd never buy a Cooler Master or Rosewill. I've seen those things literally smoke.
