Got an old Fujitsu workstation on my hands, PSU gives me headaches...

Okay, so I've recently gotten my hands on an old Fujitsu PC, Model Number MI5W-3062. Got it for less than $30, and it has an i5-2400 inside. That was everything nice about the computer, the rest is just pure OEM annoyances, the main problem being the power supply/motherboard in it...

It's a 12V only board, a small experiment from Fujitsu to move all the voltage regulators on the motherboard and only have 12V and AUX come from the power supply. I guess it kind of makes sense on paper, but as everyone can probably guess, it never caught on.

My questions are simple: First off, if I had the proper connector. would I be able to run a second power supply from the female plug on the picture, and second, is it safe to use the "Paperclip Method" to use a separate power supply for a graphics card?

only way to know would be to get a voltmeter to see if its a 120 volt connection and than measure the resistance between the fires and second one to get a good idea if their will be a limit to power flow. however if you had two you will want both to turn off at very close to the same time and the only way to do that might be to have a solenoid or relay on the 12volt and use the other contacts to bridge the green to black on the other psu. or find how it currently turns on and work from their

Perhaps, but I wouldn't put my money on it, because the PSU is rated at 250W, although since it's a 12V only PSU, all 250W goes to 12V lines (and the ~11V AUX line). I wouldn't even dare to use anything more than a low- to mid-end GPU with that PSU also running everything else in the PC. I would just like to know if the second plug on the back is, in fact, a power output, and if so, I'd like to know if there's any limit to the power flow.
