Question about Apple Computers & Internet
There are 4 pins in a trapezoid arrangement. The two that are farthest apart go to case ground. The other two do not. What are they? Both +28V? One +28V, one -28V? One +14V and one -14V? (The unit is rated at 28VDC out). If you can help, please make sure to tell me, looking at the plug, which pin has what voltage. Thanks.
Any power supply with the same pins will do. Just choose a good brand and with same rating or better higher(400 watts or more).

Sounds like it's not grounding properly. Safest thing to do would be to replace the power supply. Hope this helps.

When you have this problem on this PC, do not replace the power supply or the motherboard until you have first tried pulling out the video card. When the video card fails it can cause the x1700 to not power up. Pull the video card and see if it will power up without it.
