I was replacing my old 8800GTS with a GTX560, running on a PCIEx16 1.0 slot. 750W power supply.
I somehow reversed the 'polarity' of the molex connection on the molex-->6pin PCI adapters for my new gfx card. When I powered up, my power LEDs flashed on and off and the machine would not boot until I killed the power. The mobo no longer powers up, beeps, or anything.
This is the first time this has happened to me in over 10 years of building PCs, so I could use some advice.
Reversing the polarity on those adapters would feed the card +5v on each plug instead of instead of +12v on each plug. This leads me to believe the card was underpowered and somehow caused a surge by trying to draw too much power through the PCIEx16 mobo slot. Has anyone else seen something like this happen?
If that didn't cause the mobo to fry, has anyone seen a graphics card fry a motherboard for any other reason? Did I nuke my new graphics card?
If I somehow did damage the gfx card, can the card fry my new replacement mobo, even when hooked up correctly?
Thanks in advance everyone.
