Question Did I Just Fry My System?

[JudithWright]

I just finished a PC Build, everything was fine - I installed Windows 10 and downloaded all of the updates without a problem.

I then tried connecting 3 Fans to the top and rear of the case. I think I might have done this incorrectly - and now the PC will not turn on at all.



Specs:

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 be getting some of these terms wrong, but the CoolerMaster Case Fans have a PWM cable (with three female connectors) that I connected to the motherboard.

I connected the extra PWN cable extension to the rear Apevia case fan.



The Apevia fans have both a PWN cable and a Molex cable that can be used for power, so I connected the other side of the rear Apevia fan cable to the other two Case Fans (on the top of the case).



So, basically, the rear case fan was connected to the 2 CoolerMaster Case Fans (with PWM) and then to the other 2 Apevia Case Fans (with Molex).

All of this was connected to the SysFan header on the motherboard.





Would this be enough to fry the system (or at least damage the motherboard)?

Why is the system not turning-on after connecting these fans?



(I disconnected all of the Apevia fans, and the system still does not turn-on)

If you have all case fan power cables connected to a single SysFan Header, it's overload, but I don't think the Motherboard is fried. I guess you know RGB and ARGB headers are different, and you can't use an RGB cable to plug into ARGB header. Motherboards typically 3-4 Case Fan headers. I use Corsair RGB Case Fans with the Lighting Pro Node. It works with iCue. Just trouble shoot by reverse process. I'm fairly certain your PSU is bigger than 600 watts. I'm using a Corsair RGB 650 Watt Modular PSU. I wouldn't put the Case side panel back on until you have your PC booting up properly with RGB Case fans working and lighting up.

I forgot to add that part -

It's just an Apevia 450w PSU ($25 on Amazon)

Ok, buying a bigger power supply you may want to consider, and I don't know if you are running multi SATA HDDS and or SSDs. I will tell you that I had a Dynex 450 Watt over 11 years ago, and I had an Asus Micro ATX MB and there were sparks and smoke coming from back of the case where the PSU was at the bottom. I took it to Best Buy Geek squad and this geek squad agent thought the motherboard was fried and used their PSU to boot my PC up and it did. The Power Supply died because I had more components than the required amount of wattage. I went to the past Tiger Direct 30 min from where I live, and the tech there said I should buy at least a 550 Watt PSU and I bought my first Modular Corsair PSU, but it wasn't RGB. Less trouble to buy a bigger Modular PSU Bronze certified, and you got more power to work with, meaning more cables. You may just need to spread out RGB cables and connect to a few RGB Headers. You've got a few troubleshooting steps. You'll work it out by root cause.

The case has its own fan controller, so nothing RGB or ARGB was connected to the motherboard - it was only a regular PWM cable (with a total of 5 fans connected to it).

I really didn't think the PSU was too small because there is no GPU

Well there you go. No GPU and having to power a cpu on it. Well I thought I could be of assistance but I had the wrong solution. Well I tried.

If you are using a fan hub, does it have independent power?

Based on what you wrote you plugged nothing into the CPU fan header? Sys_Fan is not a primary fan header, usually used for the rear exhaust. If you want all your fans controlled the best place to plug in would be the CPU header.

Give that a try before anything else. Many systems will refuse to boot without an RPM signal on the CPU fan to prevent damage to the CPU.
