| Apex Master Tech Apprentice | Re: Guide: PSU Connectors Reference Thanks for the rep and support. I hope it will be a worthwhile reference to someone doing a sleeving job who forgets to label their wires. I will edit it and add the forgotten ATX 6-pin connection now. Thanks again guys! Edit: rev 1 is done. Let me know if you find any errors. Thanks! Last edited by cipher_nemo; 28-July-06 at 01:33 PM.. | |

I second the sticky suggestion. This will most definately come in handy for my next sleeve job. It is a pain to label all the wires. | ||||||||||||||||||||||||
