Do I have a P4 power supply?

I bought an open box Sparkle power supply at a computer store I trust. It's 300 watts.

My question is this: It has a power connector I don't recognize. The standard motherboard power connector is labeled "P1" and this other one is labeled "P2". P2 is smaller and looks a little like an oversized floppy power connector. I can't remember what the secondary connector for the P4 supplies looks like. Could this be a P4 supply, and can I use it with my ATX board? Anyone have a link for a pic of the secondary P4 connector so I can compare?

Thanks guys.

Not sure about your particular unit, but if it is ATX 2.03 compliant it will have the 12V connector for the P4 mobo.

You sure, you're not looking at the extra AT connectors for AT motherboards?

That has to be AT power supply connectors. Just in case you are buying a power supply for your dead power supply for your old computer.

The Sparkle 300BT had such a connector like you said.

Some power supplies have both connectors, like some motherboards have both connectors for AT and ATX. As for the hard switch like the AT power supplies, it could be accessed by motherboard instead of directly to the power supply.

If it has a small square connector with 2 yellow and 2 black wires, that's the +12v connector for p4 boards. You may also have a small flat connector with 3 black 2 orange (+3.3v) and 1 red (+5v) which is an aux. power connector. Some of the newer Enermax units have a fan monitoring or fan control plug, not sure if Sparkle has this. Looks just like a standard 3-wire fan plug.

In any case it will function just fine with 2.01 boards, you just have wires with no place to go.

Ok, well it sounds like this is not a P4 supply. It doesn't really matter (not in the market to buy one soon), and yeah, it works fine on my Abit BE6-II. I think it must be some sort of aux power thing. It's not an AT power cable, I have an AT supply and it doesn't look the same. But it's not the P4 one, it is larger and flat and I think it has 5 wires, but I don't remember the colors (I am using it to type this so I can't check). Anyway, it would seem to not be important, so lets call it a finished thread.
