Thermaltake litepower 650

Can a thermaltake litepower 650 power a gigabyte radeon r9 280 OC because it says that the card requires one 6-pin and one 8-pin connector for it and i have no idea about that stuff at the moment.

can handle fine for it.

Yes it will be fine - the psu has 2x 6+2 pcie cables. With plenty of amperage on the 12v rail.
A 6+2 pin cable means it can be a 6pin or 8pin cable.

Thankyou so much!!!
