Hi, today I got burned one of the chips above RGB header, my PC turned off immediatelly. I disconnected the led strip and after turning it on, it turned off after about a minute, but after third turn on now everything works fine, but I'm not sure if I have to buy a new motherboard ASAP or I can use this without connecting anything near the RGB header.

 

I attached a photo what it looks like above that RGB header. I did not find anything else burned.

 

Specs:

 

PSU: Gigabyte P550B

Motherboard: Gigabyte Z390 D

CPU: Intel Core i7-9700K

CPU Cooler: Arctic Freezer 34 duo

GPU: Gigabyte GTX 1660 Super Gaming OC

RAM: Gigabyte 2x8GB 2666 MHz

M.2 SSD: Gigabyte 256GB

HDD: Seagate 2TB 7200rpm

Case: Silentiumpc Signum sg1x tg rgb

Thank you for fast reply, but I won't be able to get to the shop where I bought it, at least for a week or two.

 

I forgot to add that I tried GTA V benchmark withou VSync and everything was okay, went as it had to, I'd like to know for now if it's safe to use it until I can go to that shop with it?

Open an RMA with Gigabyte directly.

I would like to, but I'm from Slovakia, and as I checked now it is only for USA and Canada.

It's most likely a transistor or mosfet, think of it like a very fast on/off switch ... I assume it's there to turn on and off thousands of times a second the electricity going to the strip, which results in your eyes thinking it's different brightness levels.

A broken transistor is either failed short or open - open means there's never gonna be electricity going to the header no matter what command the led controller sends ... failed short means it's stuck always on, which could result in the transistor overheating

 

Put your finger on top of it, if it's not very hot, then it should be safe to use the motherboard as is ... but you should send it to warranty eventually.  You can safely put the finger on, you're dealing with 12v at most, so there's no risk of electric shock.

 

ps. looks like it's the transistor that controls the green, it sinks green color to ground ... so in theory if you use only colors that don't use green at all, you could continue to use the led strips safely.

For safety of the components I turned off the PC and the PSU, after turning it off I did not wait, so only a few seconds and I tried to touch it. It was not hot and I did not feel anything warm there. Does that mean if I won't use any led strip, that it's safe to use that mobo until I can go to the shop with it?

Yeah you should be fine with it like that.

Okay, thank you for info and fast reply :)

Gigabyte has an RMA location for Slovakia -- Their site even mentions Slovka Republic.

Gigabyte ships / sells their products (e.g. GPU, PSU, motherboard) worldwide, so I don't see why there isn't location(s) near your country.

 

Looks like what burned is a regulator / transistor for the RGB header.

I didn't know that Gigabyte has an RMA location here, thank you :)
