System powers down following recent PSU upgrade
System powers down following recent PSU upgrade
Yesterday I changed my power supply from 850w to 1000w. Now my computer shuts off during games and the GPU seems to have low usage. Monitoring tools show the GPU load between 1-5%. Could the new PSU be faulty? I bought the Corsair HX1000. Maybe the connectors are too snug? I noticed the power cable wasn’t fully inserted into the outlet, but would the PC start if it weren’t? I remember plugging it in completely when first installed. The connectors might be too tight, or maybe the case isn’t fitting properly. What could explain these shutdowns and low GPU activity? I’m just starting with PC building.
I was thinking about repurposing the old cables from my previous GPU, but I learned that using them could harm the PSU. So I went with the new ones instead. My system specs are: i7-12700K at 3.6GHz (original), EVGA RTX 3080 FTW3 with 32GB 3200MHz TRIDENTZ RGB RAM, 960Evo 1TB M.2 drive, and a Corsair Hx1000 PSU. When I built the PC, the connectors were tricky to fit because of the limited space in my Lian Li dynamic EVO case. I was worried they might be forced too much, possibly damaging the components.
Remember this: Avoid using cables from another modular power supply since connector placements can vary, leading to incorrect power delivery and potential damage. Unless you're certain the cables match, it's best to double-check. Sometimes 24-pin connectors are tricky to fit, but once they work, you're good. Always verify your power connections before use.
No, I didn't experience any restarting problems prior to the PSU replacement.
I’ll attempt to reinstall the power supply next; the motherboard connector might be removed in the process.
After you reposition your power connectors and no improvement occurs, consider asking a friend to inspect the PSU. Simply bring your replacement to their machine, connect the PSU without mounting it in the case, and run some tests. If everything functions properly, the issue likely lies elsewhere. I experienced similar problems with a prebuilt system using a Corsair VS450, which would shut down unexpectedly when someone joined a Minecraft server. Interestingly, once I swapped in a new PSU (CM MWE 400 WHITE), performance stabilized. It might indicate a faulty batch of Corsair power supplies.
