My system is well overdue an upgrade, long story. Anyway I am buliding an, evga z390 ftw, with an i9 8700k and a GTX 1080. I have a PCPower&Cooling Silencer 750w PSU, it is not modular and only has one 8 pin connecter and that is for the processor. I know there are adapters to make an 8 pin connecter from 1 or 2 6 pin connectors of which there are many on the PSU. I will do some overclocking but not a lot, same with gaming, prob not a lot if any on the PC. I will deffo install only 1 GTX card, no SLI. My question is will my PSU suffice for this build or do I need to upgrade.
