Specs: Windows 10
ive got a 1200 watt power supply but when i plug my pci-e into my grahic card (msi 1080 ) my pc shuts down, then it won't start back up untill i unplug the pci-e port then it tells me on my monitor to plug my pci-e back in, so I unplugged the 8 pin ports swapped them around and still the same, but when I use my very old card, radeon 6950 peace of s--- I have no problem with my pc apart from very bad graphics and lag, not really good to play with new game, can some one help me plz

The Radeon HD 6950 is not a POS, it's just an older card. As for your GTX 1080, I believe it requires two PCIE plugs, 8-pin + 6-pin.

Please post the make/model of your PSU. 1200W isn't very helpful. Did you pay $150+/- for it? If not, it's probably not a good one. You didn't bother to post the rest of your system specs - CPU, motherboard, RAM, etc - but I'm fairly sure a decent quality 600W PSU could handle it all.

Are you sure you are not using a CPU 4/8 pin connector rather than the PCIe 6/8 pin connector. They look extremely like each other and may very well both fit but they are wired completely differently.

You have to be a little bit crazy to keep you from going insane.

PCIe connectors look like CPU power connectors and are reported to plug into the sockets but they are wired differently (I don't know what idiot decided to use similar connectors in the design but it s a bad design choice). The CPU power connectors are ONLY 4 pin or 4+4Pin connectors to make the newer 8 pin connectors. If you have a 6+2 connector then you have a PCIe connector there for graphics cards which come in 6 pin and 8 pin and some cards use two of ether the 6 or 8 pin connectors on their cards. Look throug your power supply for connectors LABELED as CPU on the plug's body.

You certainly could have a blown card. You can verify this if he is willing to try it on another working machine.
