The power supply in my e-machine T6540 computer got very noisy (surprise surprise)
So I purchased a super quite one to replace it (ZALMAN ZM500-HP).
The original Main Board Power Connector was a 20 pin there is a 24 pin socket but only
the right 20 pins were used.
The ZM500-HP has a 20 + 4 cable "Mainboard Power Connector".
There is also a 4 pin square socket on the mother board that was black black yellow yellow.
There is a equivalent connector in the hardwired cable set, the manual seys its PCI Express1
It's a easy swap but when I plugged it in I do not get any power and the LEDs do not light.
The e-machine power supply was a DELTA Electronics DPS- 300AB -15A.
The pinout on the power connector appears to be the same the at least the blank pin is the same.
So where do i start? Any suggestions?
Thanks for the help,
