Where did I go wrong?

Okay, so I ordered a Corsair 500W power supply for my HP P7-1054 and when I started to put the thing in, I realized that I am missing one plug? It's a little 4 hole plug that is on the generic 250W Bestec that came with my computer. Do I need this?

  1. check there isnt an 8 pin plug on the corsair that splits into 2 4 pin plugs

    most newer motherboards use an 8 pin connector instead of the old 4 pin one

    Are the 4 pins arranged in a single row (i.e. 1 x 4) or a square (i.e. 2 x 2)?

    Are you talking about the Floppy Diskette Drive 4-pin power connector? It's 1 x 4. If you don't have a floppy diskette drive in your PC then you don't need it. Both of the 500 Watt power supplies that Corsair sells include Floppy Diskette Drive 4-pin power connectors.

    If it's 2 x 2:

    From Corsair's Frequently Asked Questions:

    Q: Where’s the 4-pin EPS/ATX 12v connector that I need for my motherboard?

    A: Our power supplies ship with an 8-pin connector that splits in half. Use half of this connector for the 4-pin EPS/ATX 12v connector on your motherboard.
  3. They are in a little square. I don't have a floppy disk, just CD/DVD. And whew, that's good to know. Will try to put it back in tomorrow.
