So I need more power for overclocking and my current PSU doesn't have another 4 pin connector for the CPU. My Mobo is a MSI Gaming X99S Gaming 9 ACK (Newegg Link). What PSU would have another connector/what should I look for when buying a PSU for this extra 4 Pin? I know a PCI connector won't fit so I'm lost. I'll only buy Corsair, Coolermaster, or EVGA PSUs.
