Dual PSU's

post #1 of 9
Thread Starter 
Hey guys, I am looking at being able to use 2 PSU's together in one case. A server case as such.

Now I now there is a way to jump the second PSU by using a wire to jump the PSU, but I want a more PRO solution so that Both PSU's start up together and shutdown together ?

Thanks

It usually isn't worth bothering. More details, please?

Basically. MY mate has a server motherboard which takes a 20 and 24PIN atx connection. The Propriety PSU that we need for this motherboard is very hard to find in the UK. So basically we want to Re-case that server and use a Dual PSU solution, One PSU with a 24Pin and one with a 20Pin to solve our problem, this is all due to this particular PSU which is a Dell server propriety PSU being hard to find and it is no longer manufactured

Are you sure that the 24 and 20 pin connectors are ATX connectors, and not something ultra-proprietary?

Wouldn't shock me if a Dell server had some crazy odd setup. You definitely need the old PSU and a multi-meter to check it out.
If you begin from the assumption that one of either the 20pin or 24pin are standard, you start using the meter in continuity tester mode to see what's hooked to what. It may well be that the second connector isn't actually a straight 20 pin, it's an auxiliary connector to power the drive backplane or something else of the sort.

Edit: Or you could open up the old PSU and take a whole bucket of photos (edit them to label where the wires end up in some) and let the PSU gurus like Phaedrus take a look see.

From what I read they are ATX connectors, but Dell being Dell are VERY vague about the PSU specifications. There are NO specifications on this PSU which is very annoying.

Well unfortunately the PSU is not in my possession and probably never will be so either of those things are not a possiblity and the person who does have it does not have the know how to do it. Pity really.

Thanks anyway guys. I think I am going to tell him to scrap the project as its just not going to happen unless we know what we need to know about the PSU.

If the connectors are really 20 and 24 pin, then they both already have power on, if it is disabled by anyway you can just copy that adapter with 2 wires, if it is a proprietary... good luck.
