Possible short on Galaxy 1000w

[Rover3500]

Hi all,

I wonder if anyone has come across or knows what the problem might be:

I recently blew a 3870X2 graphics cards because of a short on the cards board, just before it blew (with lots of smoke) I heard a whining noise from the psu.

After replacing the faulty card I find that using 4 * 6 pin pci-e connectors works fine but if I try to use any of the two 8 pin pci-e connectors my comp starts to boot but then just shuts straight down within a few seconds and the red fault light on the psu comes on (this happens with one or both cards fitted)

I think it must be a short inside the unit, I am just wondering where it might be.

The unit is still under warrentee but that will mean sending it away for god knows how long, so I would rather try to fix it myself.

I know I can run the cards using just the 6 pin connectors but for the overclock you need to use the 8 pin.

Any help much appreciated.

well the 8pin plugs only have two extra ground wires , hence why adapters work fine.

if the psu has got a fault that has caused damage to parts of your pc and you have not modded / poked the psu with a stick etc you should be able to claim.

Hi,

It was the graphics card that caused the fault on the psu, it was my fault as when I fitted the xspc full face water blocks to the card I slightly over tightened 1 of the screws and caused a capacitor to short against the copper block (A warning to others, be very very careful when tightening the screws as there is no tolerence at all for even a slight bend in the card on the top capacitors).

If the 8 pin only has 2 extra ground wires over the 6 pin would it simply be that they have shorted in the psu case or are they on a seperate rail, as everything else works fine on the psu and all the voltages are as they should be.

Thanks.
