If you're talking about a square 4 "pin" connector: most new supplies are P4 approved, and the 4 pin cable on the PS goes to the mobo of a P4 mobo. These are called a "P4 power connector" or "Aux 12V connector". Most older P4 boards had both that connector, and one of your flat 4 pin Molex connectors so they could be used with supplies that did not have the square power connector. But you CANNOT USE BOTH, only one connector can be used. Most new P4 boards only have the square 4 pin connector.
So, if you don't have a P4 computer, you don't use the 4 pin square connector. If it IS a P4 PC, and you don't have the 4 pin square connector on the mobo, then you have to have one of the other connectors I mentioned above. If you don't connect power to it though, the PC just won't boot. I don't know what could be causing your problem. You don't say anything about the type of computer. Assuming it's not a name brand proprietary PC (one you built), and it uses a standard PS, this should not be happening. It's possible if it's a name brand PC that it uses a proprietary mobo and special PS, that may explain it--since it may require special "switching functions". If not, then I guess it's possible the PS is flaky. -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com ) http://ComputersCustomBuilt.com ----- Original Message ----- From: "Vern" I'm back with the powersupply questions again. <G> Finally installed the 500 watt power supply I bought 10 weeks ago. Didn't help my cooling problem but now when I shut down WinXP goes through the motions but the hardware doesn't turn off like before. The fans are still running after Windows shuts down. Before I would get a notice on the monitor "no video signal", not now. Windows seems to be shutting down properly as I am not seeing it do a scan check when I turn the computer on. The directions said something about a 20 prong cable and a 4 prong cable. I hooked the 20 prong one to the motherboard but not the 4 prong one. The old powersupply didn't use a 4 prong cable. I wouldn't know where to hook the 4 prong cable anyways. Is this the problem or did I do something else wrong. The computer is working as I'm using it now. It just doesn't turn the power off at shut down. Vern ============= PCWorks Mailing List ================= Don't see your post?
