GTX 550 Ti

Hi,

My computer died last evening, opened it up and found that the yellow wire on the 6 pin power connector to my GTX 550 Ti graphics card had burnt off.

The 6 pin plug, has 2 x 4 pin power connectors, must both be connected to the power supply, or is the second one a passthru connector?

Both has to be plugged in on the PSU.
If you connect both to the same PSU rail or only connect one, then the PSU's overcurrent protection may kick in when the graphics card is running at full load.

You should preferably not use those 2x 4-pin (MOLEX) to 1x 6-pin PEG (PCI-Express Graphics) adapters, because that basically implies that your PSU isn't meant to power the graphics card!

Thanks, will connect both on different rails, can only afford to upgrade one component at a time Guess power supply is next.

Could you perhaps tell us what your full system specs are (in particular: HDD's, CPU & PSU)?

Doesn't that PSU have 2x 6-pin PEG connectors?

All the decent 550W PSU's come with 2x 6+2-pin PEG connectors!

wow your cable burned off . How do you get that right. just get a decent 550w or 450w and you sorted man

Nope no 6 pin connectors, plugged both plugs into separate rails and ran the Furmark stress tool a 99% Gpu load for 20 minutes, seems I am now sorted, GW2 here I come

Yep the wire burn't, touch it and it just disintegrates ....
