OK, at this point I replaced all 24 pins on the connector, soldering very carefully. Still no power on. Figuring I may have damaged the wires inside the HX650, I went and bought a GS600. But when I plug the power in, the psu pulsates on and off!! What the $#@%??

Lol then it sounds like you've shorted your motherboard or something

My original problem remains. I believe at this point that the problem must lie in the connections inside the PSU case, which I am not confident I can fix. But the PSU is more than likely still sound, other than having whatever connections loose and in need of repair.

What would be a reasonable next step? Are there folks on here that would be willing to take a look at the PSU and repair it, for a reasonable charge? Obviously I have voided the warranty. I hate to throw it away, though, given how much time I have invested in sleeving the darned thing, and in knowing that basically this is still very likely a solid and reliable unit. Any suggestions appreciated. thanks,

Here's a page with all of the various connectors on a PSU and which wire goes where on them. You might want to use it to make sure you have all of the wires in the correct spots.

Thanks, yeah, I have double checked and all the wires are in the correct spots. :-(

You sure a MOSFET on the CPU VRM or GFX VRM isn't gone? It can do that.

Sure seems like mb. But try removing both ram sticks and see if it behaves exactly the same when you power on. try 1 stick at a time and in different slots if your mb allows this.

Here are a couple of pictures. Very embarrassing picture, considering I had spent upwards of hours sleeving the 24 pin, and then decided I would try replacing all the pins to see if that would remedy the problem... and I'd repair the sleeving later. Well, it didn't fix the problem. Trust me the original sleeving job was much much neater, not perfect but satsifactory. I cut off the connector + about 2" of wire from the end, and soldered on a replacement connector with perfectly clean pins & wires from an extension cable. So that's why it's all messed up and showing bare wires by the connector end.

Second pic is of the 8 pin extension, modular SATA power, and modular PCIE cable, from left to right.

But the PC does power on with the new PSU I bought, a GS600, so it can't be the mobo or a missing MOSFET, right? And I still can get the PSU to pass the paperclip test, but I haven't done any testing with a multimeter.

The PC isn't even powering on with just the 24 pin & 8 pin attached, so it's something core to the PSU, i.e. not one of the peripheral wires, at least, that's what I suspect.
