I have been troubleshooting several HP computers and I am trying to find out what kind of problems this power supply might be causing. (unintentionally or intetionally HP put in a bad power supply for many types of motherboards used) if you look at the motherboard most likely it needs a -5V wire on the main power connector it doesn't have one. I have had several motherboards that it eventually damaged the southbridge (controlls video and expansion slots)
Bestec branded power supplies are commonly used in HPs. As stated by the previous poster, these power supplies are somewhat proprietary but you can often fit a micro-ATX, ATX power supply in its place with a little effort and elbow grease. For example, sometimes you will have to slide forward the optical drives, install the power supply, and then put the optical drives back in place. The only case I have seen where this is not true is in some of the older Pentium 2/3 generation machines where an additional 5 pin connection to the motherboard is made. From my experience, I find Antec, Sparkle, and FSP to be some of the most reliable power supplies.
