Is my PSU fried?
Is my PSU fried?
Hello! A few days back my PC froze completely, the motherboard lights flashed rapidly—around 50 to 60 times each second. I checked all components, thinking maybe a RAM stick was loose or something similar, but without any RAM or GPU it remained the same. I removed the PSU and connected the power on pins, which kept the fan running during bridging. Once I opened the bridge, the system shut down instantly. Was this a damaged PSU? If so, what would you suggest for a replacement? I’ll share my specifications below.
CPU: Intel Core i9 9900K
GPU: Nvidia GeForce 1660 Super
RAM: 4 sticks, 8GB, RGB
Case: Asus Rog Maximus IX Extreme
I don’t need full modularity, just enough to overclock the CPU and provide solid surge protection, plus some space for a future GPU upgrade—maybe something like an 2060 Super. Thanks for your help!
PSU protection isn't strong enough on its own, consider getting a dedicated surge protector for your GPU power supply. The market offers many options—600 to 700 W should suffice, and 800 W is ideal for high-end models like the 3080. You can compare prices and find suitable brands such as Corsair, Silverstone, SeaSonic, or DeepCool. Verify recommendations on this list to ensure it's something others have considered. Higher-end models from B-tier upwards will work well.
That could damage everything. Stick to the PSU tier list and purchase a 550W or higher unit.
I corrected a mistake by purchasing a surge protector for your PSU. Meanwhile, a reliable PSU ensures stable power delivery to the GPU or motherboard, which can safeguard the VRM components. Hope your old PSU didn’t cause any further damage. A quality PSU should also shut off power before it fails, similar to how I accidentally inserted a USB-C into a USB-A port—my PSU’s protection circuit activated instantly and prevented the issue.
