Problem jumping OCZ 700w

Hello, I bought a cheap power supply from Best Buy about 2 weeks ago to test a theory and it was correct (that a single OCZ 700w was too small to power a water cooled 8800gtx sli system). I jumped that power supply using a paperclip while I waited on another OCZ 700w to arrive. Well the next OCZ 700 arrived and I tried using it the exact same way, but it shuts off. The computer runs for about 10 seconds, and then the power supply turns off so the computer makes that annoying beep.

Am I doing something wrong? Or is the OCZ non-jumpable?
 
Looking at the cheap power supply (Antec 430w) I can see that the OCZ comes with only a 20 pin connector and a small 4 pin adapter to make it a 24 pin, whereas the Antec has a 24 pin connector. I can't see this causing the power supply to shut off after 10 seconds or so though?

I think I should just go with an 1100w modular psu and sell these 2 OCZ power supplies...
 
The FSP Epsilon (which is what your 700w GameXtreme is based on) is a multi-rail PSU if my memory serves me correctly, so perhaps you have the load distribution done improperly and there is too much load on any single rail.


[EDIT: Yes, the Epsilon has 4 rails rated at 18 amps each - you may need to check out how you are loading the PSU.]


Although I hate to poo-poo an FSP unit, I would look at something else since the Epsilon design is flawed and produces high ripple ('dirty power') on the 12v rails, especially when it is loaded near it's rated capacity.

Check out the 650+ watt offerings from Corsair or PC Power and Cooling. I really like PC Power & Cooling's "Silencer" 750w unit for it's beefy single rail Seasonic design.
