Did I just fry my system?
Did I just fry my system?
I just completed a PC build, everything worked perfectly.
I installed Windows 10 and applied all the updates smoothly.
Next, I attempted to install three fans on the top and rear sides of the case.
I suspect I may have done it incorrectly, which is why the PC won’t power on at all.
Details:
Motherboard: MSI A320m Pro-VH Plus
CPU: AMD Ryzen 5 PRO 2400G
Case: CoolerMaster Masterbox MB320L ARGB (2 ARGB fans)
Fans: APEVIA CO1012L-WH Cosmos 120mm White LED
I might have misunderstood some of these terms, but the CoolerMaster case fans use a PWM cable with three female connectors, which I linked to the motherboard.
I also connected an additional PWN cable extension to the rear Apevia case fan.
The rear Apevia fans include both a PWN and a Molex cable for power, so I connected the other end of the rear fan cable to the remaining two case fans (on top).
All connections were made to the SysFan header on the motherboard.
Would this setup be sufficient to risk damaging the system or at least harm the motherboard?
Why isn’t the system turning on after these changes? (I removed all Apevia fans, but it still won’t power up)
When all case fan power cables are linked to one SysFan header, it causes an overload situation. However, I don’t believe the motherboard is damaged. You’re probably aware that RGB and ARGB headers differ, so you can’t connect an RGB cable to an ARGB header. Most motherboards have 3 to 4 case fan connections. I’m using Corsair RGB Case Fans with the Lighting Pro Node, which works with iCue. Try troubleshooting by reversing the setup. It seems your power supply is likely larger than 600 watts. I’m using a Corsair RGB 650 Watt Modular PSU. Don’t reinstall the case panel until your PC starts up correctly with the RGB fans active and lighting functioning.
When purchasing a larger power supply, consider your setup. I used a Dynex 450 over 11 years ago with an Asus Micro ATX motherboard, and I noticed sparks and smoke from the back of the case near the bottom PSU. A tech at Best Buy Geek Squad thought the motherboard was damaged and used their PSU to restart my PC, which worked. The PSU failed because it wasn’t enough for all components. I visited a store about 30 minutes away from home, where they advised buying a minimum of 550 Watts. I then bought a Modular Corsair PSU with RGB, which gave me more power and flexibility with cables. You might need to organize your RGB cables and connect them to a few headers. There are several troubleshooting steps you can try, focusing on identifying the root cause.
If you're using a fan hub, does it provide its own power? From what you mentioned, you didn't connect anything to the CPU fan header. Sys_Fan is typically not a main fan header and is often used for the rear exhaust. Placing all fans in the CPU header would be ideal for better control. Give it a shot before moving on. Most systems won't boot without an RPM signal from the CPU fan to avoid potential damage.
