I change my PSU on Saturday, and I have some issues.
I install Enemarx EGA1000EWL 1000W PSU.
I installed after I read the manual and I check all connectors.
I have some estrange problems whit the enermax 1k psu.
If I connect the Molex and floppy connector that the dfi mother has the psu always give me Power Guard Error and the computer is unable to power on.
I try whit only the mother fully connected and the VGA and I have the same error.
I install the psu without using the extra DFI power connectors.

ERROR:

RED light and two beeps interval

The manual said:
Power supply abnormal
Connector terminals short –circuited

When it happed?

If I connect the Molex and floppy connector that the dfi mother have.
Randomly when I start the PC.

Other things:
3 times happend that the PC starts but there is no post and the ati card has the red light of voltage error ON.
The voltage when playing games drop from 11.96 to 11.74 according to the monitoring software of the DFI mother. (A multimeter on a Molex connector reads no change in the 12v, but I not sure if it is a same 12v rail…)
When I get the unable to power on error (without using the dfi power connectors) if I turn the psu off and switch one of the modular cables to another position in the psu the PC stars correctly.
If I do not change a modular cable position I must wait 20m to give power to the psu and then turn on the PC.
I have 220v at the wall
I use 10 Molex connectors,1 sata,1 floppy, ATX,12vCPU,1 PCIEx

Modular cables that I use:
1x3 Molex
1x2 Molex 1 floppy
1x2 Molex 1 floppy

I need…HELP

I live in latin america and I wait over month the arrival of this expensive PSU, RMA will not be free of charge (shipping $$ and time...)
I must try everything before going the RAM way.

Thanks

I know Enermax has an history with DFI where it won't let the mobo power up due to the sensor wire..
It means that the PSU can't get a strong enough signal from the mobo to verify it's presence.. this is called the cold boot bug.

There are some tricks to jump start the PSU... there's even an option to solder a resistor on the sensor wire to resolve the matter...
