I am planning to install a GTX 770 PCIe x16. In the specs, it says that the GPU needs a 6 pin power, and an 8 pin power connectors. My power supply Cooler Master i600 600W 80+ Bronze Certified ATX Power Supply has both, but I want to install a wireless network adapter (Asus PCe N10). If I install the GPU, all the PCe power is gone. Does the N10 not need power, and if it does, is there another similar priced PSU that works?
