How to determine if the PSU is failing?
So as the title mentions, here’s how you should handle it because I’ve noticed some strange occurrences lately. In several games I play, unusual things happen to me, such as a significant stutter lasting 4-5 seconds, which then returns to normal. I’ve checked the GPU temperatures and they’re within acceptable ranges for an MSI RX 3060, but my CPU is around 5700 X3D, which is about 60 on load during gaming. My motherboard is B550 Gaming with the latest BIOS, and I have 32 gigabytes of RAM from Kingston at 3200 MHz. The possible cause seems to be a 750W EVGA GQ Gold.
I got it from someone who claimed the power supply was under warranty when I bought it, though it’s been dusty. Although he was banned from the site where I purchased it, my warranty doesn’t apply now. There’s no unusual smell, but something inside might be failing and causing these symptoms.
I didn’t mention many of the settings I used to have, mainly during startup when launching emulators such as Bluestacks, Nox, and some Steam apps. I’m losing track now and don’t know what they were. It’s getting really tiring.
Consider sending it to a specialized lab with significant equipment costs for comprehensive testing. Or, recognize the possibility of purchasing a faulty unit and opt for a fresh, reliable PSU from a trusted source, ensuring better warranty coverage.
The final item I'd purchase secondhand for a built is the PSU. It's the sole component that could cause all the others to fail if it's faulty.
It seems you're looking for advice on selecting a power supply unit that can handle higher wattage needs, possibly for future upgrades. You mentioned wanting options that support 4070 or 5070 ratings to ensure adequate power capacity.
Over the last decade of building PCs, I've used 1000 Watt to 1200 Watt power supplies without any problems. They also provide extra capacity for future upgrades.
Try to obtain another 750w psu of good quality for testing. If unavailable, purchase a replacement from a store offering a solid return policy. Be prepared to incur a 15% return charge if the new psu fails to address your issue. The EVGA unit offers average build quality and comes with a 5-year warranty. Without specialized knowledge, the warranty length is your best indicator of reliability—aim for at least 7 years, preferably more. Seasonic and Corsair recommendations are a good starting point. Think about upgrading to 850w or even 950w; the extra cost rarely justifies the gain. A psu only consumes the power it receives, not its maximum capacity. And... it will function most effectively and quietly within its rated range.
