A couple days ago I bought a Sapphire Radeon R9 270X and a Thermaltake TR2 TR-600 for my computer, my current power supply is 350W and that would be horrendous for powering a 270X, but I plugged in all the cables for the 600W supply, I plugged my new Graphics Card in, and it turned on, no beep upon powering my computer, and an infinite blank screen, no USB slots worked or anything "Lights on my mouse didnt go on" Also I tried to plug in my old graphics card in (MSI radeon HD 7750 2GB) and I had the same problem until the supply was swapped again with my old Power Supply and Graphics card, please help. Also, if it helps here are my specs without the new components.
Motherboard: 760GM-P23 (FX)
CPU: AMD FX 6300
RAM: 8GB (dont know exact RAM)
PSU: 350W (Same case here)
GPU: MSI Radeon 7750 HD 2GB
If you need more info tell me
