Anyone else ever consider converting a conventional PSU to modular?

Doesn't seem like it would be that hard, or hazardous. Take the non-essential wires: cut them close to the power supply, strip, crimp into some generic radio-shack connectors, the female end on the PSU side of course. So many PSU's are coming with gobs of extra cabling these days, has anyone tried this? Thoughts?

It should work fine. I wouldn't use radioshack connectors though, as I doubt they would keep a good connection. If you are going to do it, you should do it right with some quality connections that won't fall apart after a couple uses.

Every junction increases resistance, and oxidation is far more likely to show up there as well. If you coat the connections with dielectric grease, that should really cut down on the oxidation though.

So, where would you get quality connections? I'm looking at these molex parts, but am open to suggestions...

What you're thinking of doing is what Performance PC's does when it converted PCP&C power supplies, among others, to "modular".

You may want to look into what Performance PC's has in stock for connectors. If not them, then Frozen CPU has a ton of connectors, too. But neither place is cheap.

There's no need to buy electronic connectors from computer dealers, nor is there anything wrong with Radio Shack connectors, which come from the usual sources, like Molex, Amp, 3M, and Assmann

I just cut the wires to length to match the install and attach a new socket on the end. That way you only have one connection in the loop just like a regular PSU install. I also get rid of wires that have 2 wires coming off one connector. You can re-use sockets too just buy new pins. The pins are about 5 cents each.

For connectors mouser.com has them all ,shipping is usually about $5 and they have no minimum order. Great company to work with. If they don't have something, call them and they will find it.

What about extra wires that don't connect to anything? I'm thinking about just cutting them and heatshrinking the ends instead of attaching a female molex connector. That's also a good idea about cutting the rest to length. Not really worried about warranty, I got the Tt TR2 430W for $18.

Actually, Modelworks, could you point me to the exact kits you've used for male/female housings and pins/sockets? Having trouble finding the ones with the right indentations.
