Replaced faulty power supply with a new one, but the computer remains unresponsive.
Replaced faulty power supply with a new one, but the computer remains unresponsive.
I'm unsure what to do but I've tried two Seasonic Focus GX-650s (650W) over the past year. Frustrated by the seeming disposability of their power supplies, I purchased a Corsair CX750M (750W), installed it with the included cables, and tried booting it up. It lights on but doesn't function properly. Anyone have any suggestions? Specs: motherboard MSI Tomahawk B450 Max CPU Ryzen 5 3600 GPU Zotac GTX 1070 8GB
Connect the connection with a narrow wire at the "Power SW" location.
You're likely dealing with a wiring issue. It's wise to bring it to a nearby tech specialist who can check the area directly and help identify the problem. Alternatively, try removing any extra components like fan controllers, mouse/keyboard, case headers, or RGB parts in hopes of resolving it without a hardware issue.
You might need a screwdriver, flathead, key, or coin to connect the parts. The issue could also stem from the incoming voltage in your home power supply. Additionally, without a surge protector between the power source and wall outlet, the device may be damaged.
You could test various components with a multimeter, such as voltage levels, continuity, and resistance.
