PSU Issue?
PSU Issue?
I've been using this PC for almost two years, but lately something's gone wrong. The machine suddenly powers off and restarts after just a few seconds. I've checked various potential causes, but everything seems normal. There aren't any overheating signs, the components appear to function independently, and I haven't updated any drivers or software recently. What bothers me is the voltage on the +12V rail, which often spikes up to around 13V during stress. I don't have a photo of it, but I've noticed it can reach nearly 14V at times. This issue seems to affect my entire setup: CPU (Intel Core i5-12600K), cooler (ARCTIC Freezer 34 eSports DUO), motherboard (Asus Prime H670 Plus D4), GPU (MSI Radeon RX 6600 XT Mech 2X 8G OC), power supply (Corsair RM750x), and case (Cooler Master MasterBox TD500 Mesh). The operating system is Windows 10.
