I just installed an Achieve 500 watt power supply (model #AX500.N) in an HP d530C tower. The new p/s was $110(TT) at Supertech in Couva, no arguing with that price. The ratings on the label are +3.3V 28A, +5V 45A, +12V 25A, -12V 0.8A, -5V 0.5A, +5VSb 2.0A, Output 500W. The old p/s was an odd shape and the holes on the new one are different from the old one. Also the old unit made 240 watts. The tower being fed had one HD, one CD-ROM, one floppy drive, and one motherboard with everything on board.
Looking at the back of the tower, only the right side screw holes lined up properly on the p/s and case. The left side holes on the p/s were slightly inside the inner edge of the opening for the exhaust fan on the ps. There was enough space to let the screws go in and the head of the screw to catch the edge of the case and secure the p/s. The Achieve unit is shorter/flatter then the old one so there is now a half inch space below the p/s and the opening for the p/s fan on the back. I left the space open but I am considering taping the space to encourage air to be pulled in from the openings at the front of the case. So far it runs nice and quiet, no hiccups, and I don't expect to see anything coming up soon.
