PSU Cashing Problems Occur
PSU Cashing Problems Occur
I possess an older budget setup I created at the end of 2019. It features an i7 9700 and an RTX 3060ti, with a Gigabyte B365m Wi-Fi card that’s highly durable. The power supply is an 80 Plus gold unit rated for up to 600W. Recently, I’ve noticed frequent blackouts and restarts across various games. Initially, I suspected the GPU was failing, so I swapped it out for onboard graphics, but the problem persisted during Cinebench tests. My main concern now is the power supply might be failing. I’ve ruled out RAM and the GPU since they functioned properly in my older 6th-gen HP system. I don’t have another machine with a 9th-gen chip for testing. Would it be worthwhile to purchase a replacement PSU to test this further? It seems like a relatively inexpensive option, and I’m considering whether a failing NVMe SSD could be the culprit given its age. I rebooted from Windows 11 to Windows 10, reinstalled drivers on a new 1TB SSD, but the issue remains. It’s surprising that the Bequite PSU could be at risk after five years.
Does it ever perform under light load? Monitor for overheating. Perform a thorough clean, reattach components, install just the CPU and hard drive, use only essential RAM and storage. Verify all power connectors are secure, no frayed cables. Ensure fans and pumps operate. Disable any overclocking if present. Leave the case open to allow proper airflow. Start in safe mode or a rescue/recovery disk, test stability at idle. Slowly increase load with benchmarks while watching temperatures and system status.
I attempted that but it shuts down immediately because of the high CPU usage, like when I start a Cinebench test. I could try a cold shutdown to let it cool completely and check if the test runs longer, but the temperature reading on the fan control shows around 30°C at idle. With my 120mm tower cooler on a 65W chip, I’m not sure how it would handle heavy loads—my system just stops under stress but has run for hours while browsing or watching videos.
it might be the PSU but that seems improbable with just a low-power CPU and high CPU usage. The best way to confirm is to replace the PSU first (corsair RX 650W minimum is recommended). Sometimes these problems are linked to RAM issues, or maybe the CMOS battery isn't holding charge well (common in older systems). Another option is to disable XMP profile settings and reinstall Windows.
I handled a lot of that; I think the problem is the power delivery since it works fine on my 6th gen HP and the GPU too. But I can't test the CPU, PSU, or motherboard, so it seems like a power supply issue. I guess if I had a proper tester, it would definitely fail. These units are probably cheaper nonmodular models, maybe just holding on by a thread. I put a lot of effort into this during Corvid.
It was fixed successfully and passed all stress tests. The replacement of the PSU with the RM 750W 80 Plus Gold Corsair modular unit made a huge difference, and I’m fully back in the game now.
