Hey guys, I just bought a new GPU R9 280x and I connected it to a Sentey 450W Power Supply (very shitty). I had been using it the last couple of days underclocked without any problems. I also had connected both power pci express conectors (don't know if both are required, would like to know aswell).
Problem is my PC just shutdown and won't turned on for a brief period of time (5 mins). I'm now using the onboard card.
I have a shitty CPU Athlon II X2 250 so it doesnt use much power consumption. I'm only using this PSU until I get a new one next month, can it hold on that much? Can something go wrong if I reconnect the GPU?
