Dell OptiPlex 780 DT Power Supply Upgrade

[Tailz94]

I have been working on my project Dell OptiPlex 780 DT and have upgraded everything but stuck on the PSU.

My 780 DT came with the 255W PSU model DP255P- 00/CN-0FR597-99999-08P - 4HX0 - A01.

What my issue is that I've purchased this PSU for the added power and connectors https://www.atxpowersupplies.com/350-Watt-Dell-F5114-Power-Supply-F5114-350W.php and the connector on it is of the regular 24-pin ATX connector whilst the standard 255W PSU and the motherboard is of the smaller 24-pin ATX or mini 24-pin ATX. Now that I've got the issue that the power supply can't plug into the motherboard but fits well in place of the 255W unit.

I need help matching up the colours from the different power supplies plugs so I can splice the old mini ATX with the new power supply. I have purchased the converter plug on eBay http://www.ebay.com.au/itm/282434966554 and still waiting for it to come. But im not totally confident that it may work despite it saying its compatible with my 780.

Any help with getting colours crossed match so I can have the option to splice if my converter plug fails. Ill get photos of the connectors asap.
Thanks a lot in advanced!

If you have found a 350W PSU that fits it's big news for DT owners. The only advice I can give is to look at the label on the old one and see how many 12V rails it has. Probably 2. They will have white wires on 1,and yellow on the other. If the new PSU has 3 then the third one will have a colored trace on it. You will need to be sure not to overload any of them. You can figure out the other rails the same way and map your old connector. Expect each rail to have it's own separate ground circuit and color code.
