You can find the pinout for it here:<br />http://pinouts.ru/Power/atx12v_pinout.shtml<br /><br />If you have this same connector with 3.3, 5 and 12 volts your are probably looking at a proprietary power supply.Viktorhttps://www.blogger.com/profile/08123118383316924219noreply@blogger.comtag:blogger.com,1999:blog-3030619748984253626.post-40330804696376296162013-04-16T10:52:54.525-07:002013-04-16T10:52:54.525-07:00hi, i´m on this project right now.

I am connected and writing to you from a Compaq EVO 510 sff and the better of all is that the new psu has a very small mobo and it fit perfectly into the original compaq psu case. The most problematic was to find the optocoupler, but I found one in an old Xerox Fax.<br />I enjoyed very much this project because I succeded. Now I would like to ask for your help with another project, it is a lab centrifuge that has a missing component in the mobo, it uses an ULN2803A to control 2 relays. Please let me know how can I send you the details of this centrifuge. Thank you very much and I hope that you can help me.Dr Isidrohttps://www.blogger.com/profile/02987488910766014386noreply@blogger.comtag:blogger.com,1999:blog-3030619748984253626.post-2084959188810617062011-03-04T13:49:31.277-08:002011-03-04T13:49:31.277-08:00No problem.
