Your power supply unit failed!
Your power supply unit failed!
I maintained my computer and updated the thermal paste. It functioned properly until I restarted it. A popping noise and sparks came from the back of the CPU, and I noticed a burnt smell. Right after that, I took out the GPU and attempted to power it on, but it failed to start. Over time, I installed a temporary PSU to test if the original one had failed or if there was another problem. It appears the PSU stopped working unexpectedly, though all other components, including the GPU, were intact. An electrician inspected the power supply and confirmed it was fine. I’m still puzzled about the cause and why this happened despite everything being in good condition. My PSU is only two years old. The specs are: i5 12400f, 8 x 2 DDR4 RAM, RTX 3050, Gigabyte 450W Bronze (450B), Asus P600M-E motherboard.
It seems there was a small issue with it. Occasionally things go wrong. Luckily, it didn’t affect the outcome because power supplies often handle failures gracefully.
I experienced the same issue with one of my earlier PSUs. It was only two weeks old and I had just completed assembling my PC. Everything worked fine before I started putting it into the case, and it functioned as a collection of components. Sometimes these problems just occur without any clear cause. However, you managed to identify the faulty part. Replace it, double-check the connections, and enjoy your system! (Could be a loose screw or something else accidentally dropped inside?)
A few producers offer extended guarantees for their power supplies, sometimes even up to gigabytes... It’s a good idea to verify if it remains covered.
Sure, here are some solid PSU options. For a 450W setup, consider a 500W unit to ensure reliability. If you're planning for higher loads or future expansion, opting for 550W could be wise.
I haven't found any excellent PSUs, but aim for a well-known brand. (started with a namebrand, though they also offer lower-quality options... + just bad timing) I'd choose a 550-watt unit since it provides extra capacity for future upgrades. Without that, you're less likely to overheat your PSU or strain it. Personally, I use an 800-watt Zalman PSU. Most people don't suggest Zalman because it's not widely recognized, even though it's reliable. My setup only requires about 400-450 watts. I can tolerate a dusty PSU without issues (though it's still not ideal).
