This ASROCK b450m Pro4 isn't turning on at all.
I just swapped my old Intel CPU/motherboard for a Ryzen 5 3600 on an ASROCK b450m pro4 board. Installation went smoothly, but when I tried to boot the system it won’t power up at all—no fan noise, no lights. I’ve done the following: rechecking cables, GPU, and RAM; testing the board with only power cables connected; trying a direct PSU connection from outlet to motherboard; manually shorting power pins on the board. I’m hoping it’s just dead despite careful handling. Any guidance on what to do next would be super helpful. Thanks!
Specs:
- CPU: AMD Ryzen 5 3600
- Cooling: AMD Wraith Stealth MOBO
- GPU: NVIDIA GeForce RTX 2060
- RAM: 2x 8GB DDR4-2400
- SSD: 240GB WD GREEN, 6.0 GB/s SATA III
- HDD: 1TB 3.5SATA III, 7200RPM
- PSU: ATNG ATM-600FB, 240V
I reviewed it once more and didn’t spot any clear issues. There are no bent pins, scratches, or damaged edges. Just a normal look.
After reviewing the details, it seems the power supply unit is likely the problem. The symptoms often point to a faulty PSU. Replace it as soon as possible, even if it doesn’t fix the current issue—it can help avoid hardware damage from a poor PSU. This risk might be higher here, and a better unit could prevent more serious failures. The tier list can guide your choice.
