Is PC P&C still a good brand?

I've always heard that PC P&C was a top brand, but this is the second DOA I've got out of 3.

the first DOA was a new PSU, turbo cool 510 I got from ebay. it made the computer unstable. sent it back to PC P&C, and they were very good to deal with and sent me another one. that one is still going strong. This was about the time on the OCZ takeover.

I just got a 500 silencer and it wont power up the computer in or out of the case, but it does turn on when I try the jumper test. An old 1u I have laying around does fire up the computer in question.

Anybody else have back luck with PC P&C or is it just me? (like my 3 out of 4 bad gigabyte mobos)

I've had good luck with PC P&C PSUs, though I've never tried anything lower than the 610W unit.
