Experiencing PC crashes when using a new power supply under load?
Experiencing PC crashes when using a new power supply under load?
Not long ago, I switched from a 1070 and a 1700x to the components I currently use (3080 and 5800x3d). I maintained most of the setup, including a Segotep 600W Gold-rated power supply, and everything functioned well. My PC required about 750 watts, so I planned an upgrade. Initially, I looked for a suitable PSU on a marketplace and found an Enermax DF 850W. However, once connected, my GPU began to click and flash red lights, and the system failed to power on. After some research online, I discovered my GPU wasn’t getting enough power from the original PSU. Instead of purchasing another one, I bought a new Superer 750W Gold-rated PSU on Amazon. Within days of delivery, I used the Segotep without issues. I tested it for about three hours while streaming anime, then tried launching a game which caused the PC to shut down completely. It had to be unplugged and reconnected before it would power up again. To check performance under load, I ran UserBenchmark, but it crashed after 60% completion. It seemed odd that my Segotep worked perfectly while the Superer caused problems. I wondered if my surge protector couldn’t handle the higher wattage or if something else was at fault. Any suggestions? My system runs Windows 11 24H2 with a Ryzen 7 5800X3D, RTX 3080, DDR4 32GB, 3200MTs, ASRock B450M-HDV R4.0, Superer 750W Gold, 64-bit, Windows BIOS v10.31.
I ran userbenchmark once more and it failed right away when it reached the GPU section. The computer then shut down completely.
You altered the PSU without realizing it. Please let me know if I overlooked something.
This PSU seems unlikely to be a genuine 750W gold model, which explains the problems. Common concerns include random brands, unusual power ratings, and missing reviews. It probably just rebranded an inexpensive generic unit. Did you connect old cables with EnerMax? That’s often due to shorting or overcurrent protection from those parts. The Enermqx is definitely capable of handling the 3080, but it might be a faulty product. The 600W model is being pushed through, which is fine, though it could indicate you were scammed. The 600W unit isn’t failing—it’s just being used beyond its limits. If this is the Segotep GP600, it’s perfectly okay to use.
I aimed to increase the output by upgrading to a higher wattage supply. The calculator suggested a 750W unit, and I also passed my Segotep to my brother for his initial project.
I don’t have any old cables with the Enermax. My Segotep isn’t modular like that, but it uses an Enermax. Everything about it looked brand new when I bought it secondhand, and the wires were sealed in bags. I’m not sure what’s wrong with the Enermax, but I think it might be a scam. I ended up buying a new one, and it still seemed like a bad choice for my PSU. The Segotep is a Gn600; I thought I needed 750W according to calculators, so I wanted to be safe and upgrade. I also gave the Segotep to my brother for his first build.
The SegoteP was actually a solid PSU, along with the Enermax—it seems like it might have been mislabeled or sold off. The new model looks much better as a reliable fire starter, so it’s best to replace it before any further issues arise. There are plenty of options in the lower tiers or higher wattage models; consider upgrading to something around 750W or more. The SegoteP can handle the spikes from the 3080s, while other units struggle, so the 750W recommendation makes sense. Power surges are usually within limits, but the SegoteP just doesn’t seem to mind much and keeps running smoothly.
Hi, I set up the cooler master successfully now. While installing, I noticed the motherboard cable connects at two spots on the PSU. This was unexpected since it wasn’t something I’d encountered before. After some reflection, I realized that during the Enermax installation I didn’t connect both cables to the top and bottom of the PSU as shown in the photo. I’m now questioning whether the PSU functioned properly given this setup.
