My CPU is an i5-9600K overclocked to 4.9GHz (stable) with the voltage on auto and max power consumption on 1000W (default: 95W) that never goes above 65°C. At 5.0GHz the system still boots, but Windows (10) crashes usually after I type my password. My motherboard is a Gigabyte Z390 Gaming X that alongside the 8 pin connector has a 4 pin connector, but my 650W PSU only has one 4+4pin connector. Which one of this is the problem:
a) Voltage needs to be manually set
b) The 4 pin is required
