    specifically you need to connect green wire with any black wire, google for pinouts if in doubt

    Using the paperclip trick to turn on the ATX PSU

    [​IMG]
    Connectiong PS_ON (green) to COM (black) on the ATX motherboard plug using a paperclip as shown here turns the power supply on. Means the 12V/pci-e power outputs will then be active.

    If leave the paperclip attached in this way then when you connect attach the mains cable into the PSU, it will become active. If that's a bother, then can replace the paperclip with a small on/off switch OR have a switched mains lead into the PSU as Max_Headroom has. Shown here.

    No one has reported a successful x2 1.0 implementation as yet using a PE4H.

    Could this paper clip technique blow up the PSU?

    Also how dangerous is this?

    Its not dangerous at all, if connected to a motherboard it does the same thing when you turn your computer on. Theres also no danger in working with 12v either, you could grab + and - leads and would not be electrocuted...

    Once you get to around 50v+ there's the possibility of being electrocuted in general...

    Both lights on the PE4H should turn on after you do this and the fan on the GPU will turn on as well...

    My Studio PM55 i7 720qm has been shipped so it will be available for testing and I could probably get a 2 video cards for testing if there is any speed improvement on the PM55 now I only need a PE4H or PE4L to try it out...
    Maybe MexicanSnake can lend me his PE4L to do some bench marks wink wink elbow wink

    It's a no-name regulated switching power supply from Hong Kong, sold at eBay for $33, free shipping. It is not an ATX computer power supply, and only provides a 12 V output at 15 A (180 W). It is much smaller than standard ATX supplies because it omits the 5 V and 3.3 V outputs, and the 12 V output is weaker. As my graphics card draws about 150 W on maximum power, this is just about perfect.

    The power supply contains a switch to select 110 V or 230 V operation. It is fanless, and can be used with grounded or ungrounded power outlets. I used standard cable lugs to fasten the cables to the input and output terminals of the power supply.

    I've had time to test the power supply and external graphics card thoroughly during the last couple of weeks. The setup has worked perfectly, even for long continuous gaming sessions of up to 12 hours.

    If you need more power, try searching for 12v 18a on eBay. You'll find some nice looking Dell thin client power supplies (216 W). I went with the lower rated 180 W supply because it was much cheaper for me when shipping cost was taken into account. (If you live in the US you'll probably get cheaper shipping though)
