Guys, I only a few days ago bought a new 350W "True Power" supply to replace my old cheapo 400W that went on the blink (quality not quantity) and this came with a 24 pin connector.
My Asus P4P800-E has a 20 pin on the board and all I did (and it's worked flawlessly since) is leave the last 4 pins hanging off the edge! That's a red, yellow, orange and black wire.
Unfortunately this mobo has a bloody IDE connector right in the way of the last four so i cut them off with a scalpel, making sure to cut the wasted side of the four, not the good side of the 20 lol
Job done, no need for a converter. btw, the guy at my local computer shop didnt believe me that this worked so he tried it on his Athlon system in the shop...guess what, bye bye the need for extra connectors.

:wink:
