The computer won't receive power for an extended period after turning off.
The computer won't receive power for an extended period after turning off.
Recently, about two months back I noticed a recurring issue. When I powered off my PC—something I usually do once a week, or else it would run nonstop—I found all the lights in my case extinguishing as though there was no power. Even after switching on or off again, it took 30 to 40 minutes for the PC to come back to life when the power switch was off. This became frustrating during blackouts, especially since I recently replaced my PSU 15 days ago due to multiple power cuts in my area when I wasn’t home. I also changed my PSU and processor, but the problem persists. There seems to be a pattern: power loss after shutdowns, followed by long wait times before functioning normally. I’ve tried unplugging the PC and holding the power button, but nothing worked—it felt like the motherboard lacked power. The specs are as follows: Processor: Ryzen 7 5800X; RAM: 32GB DDR4 XPG D60G (8x4); GPU: GTX 1050 Ti OC Edition; Motherboard: Zotac Mobo B450 Elite V2; GPU: Samsung EVO; SSD: 512GB NVMe; PSU: Cooler Master MWE 750W Bronze V2. Case: Matrix X Mesh with Deepcool fans from Cooler Master (model unknown).
Blackouts and brownouts are coming, so invest in a 1000W surge protector unit. This lets you connect monitors and printers safely. It delivers steady, clean power—perfect for streaming videos without interruption. The battery ensures a safe shutdown at the right time, preserving all data. You’re prepared for outages instead of risking damage from a failed PC. You’re right—this setup gives you confidence during emergencies. You might also consider higher-quality PSUs like Gold or Platinum, but keep the wattage reasonable.
I understand you're experiencing problems with your PC after the blackouts. This only happened recently, and your previous computer was replaced by a new one. The old UPS stopped working after years of use, which caused power issues. You mentioned ordering a new UPS now, but you're concerned about the case not receiving power during shutdowns. If you try to shut it down manually—like when going out or cleaning—I’d need 30-40 minutes with the PSU off before it starts working. Turning it on early would cause delays of that same duration.
The UPS failure didn't harm your parts, but the PSU was affected. Are you sure the old PSU was replaced?
but how could this happen? I thought an ups safeguards the "components." It's strange that under these conditions, the psu and cpu (?) failed since op had an ups at that stage if I'm right. This isn't a good approach either, especially if you're aware of frequent power outages in your area. It seems we really can't fix this problem now, but we could try to prevent it from occurring again—perhaps by using a high-end ups and shutting down the pc when not in use would be a solid first step.
