I have a 5-yr-old Deepcool MATREXX 55 V3 ADD-RGB WH 3F and the power button has started giving me issues. It gets switched on sometimes but never at one go. Yesterday, it didn’t get switched on the whole day. Today, it took a good 10 minutes before it got switched on. Once it is on and running, the PC functions properly and I have not faced any issues. However, I think the button might be the issue here. So, is it possible to repair or replace the button and wiring (without a lot of pain) or is it time to get a new cabinet?
P.S. I had asked a local PC repair guy and he asked me to get a new cabinet.
Yes. Get one of those aeroplane like switches with red cover and mod your cabinet.
Yes. It can be repaired or replaced. you can also get one that is outside and close to your keyboard mouse. Essentially, you can mod it to your hearts content. There are easily and direct replacements available easily.
Any purchase links to such replacements? How do I go about it? any DIY videos would be available? Not much of a tech guy.
Write to the Deepcool support using this form and explain them your situation and ask for the front panel replacement of the cabinet:
The thing is pretty simple. Getting a full set will make it easy for you to simply disconnect the headers of the power switch on your motherboard and put the headers of the replacement, and you are ready to go. It is pretty simple. I am an idiot and I have done it several times. This will be the least amount of pain since you will not have to dislodge anything in the cabinet frame. You just need to remove the relevant pins and replace them with this, and your job is done.

I have already written to them. Was waiting for their response when I thought of creating the thread here. Anyway, thanks for response.
700rs for 50 grams of plastic and 3 wires seem a lot to me but it’s a niche item so kinda understandable.
Wow, so much for a “repair guy” huh. Anyone who repairs and respects the hobby knows you don’t just throw out a 6k PC case.
swap the start and restart headers on the motherboard if you have two buttons on case.
No restart button on this case.
Just googling ‘start button computer cabinet header’ gave me two cheap options.
I have no idea if these are good or seller/site is good. Check it yourself.
pc part sellers ideally should have cheap options for things like this, or pc bell etc. I dont know if they do. Pretty sick to suggest new cabinet just for this. Capitalism at its finest.

Sad. That’s exactly what I did on mine and it works perfectly now
Since the cabinet is premium in its heyday it’s always better to get the start and reset buttons replaced and use it than using some alternatives.
Once when my Corsair 300R cabinet start button went kaput after its warranty period I asked for a replacement and Kaizen Infoserve sent me free replacement outside the warranty period but asked me for shipping charges which was ₹350 and I got a new start button.
Total panel will be underneath and they usually give the panel along with front panel cables if attached or just the panel if the cables aren’t attached to it.
For Corsair 300R they gave me the panel only.
My Corsair 300R front panel underneath.
Deepcool replied. Seems my cabinet has been EOL for some time so they wont be unable to arrange spares for it. Have ordered the external switch from Amazon.
Ordered.
Edit: Missed your comment where you said your case doesn’t have a restart button.
Several years ago, my power button stopped working properly, and I needed to press it multiple times with force. I couldn’t find spares so I just switched the power and reset cables, and my reset button worked as my new power button. Worked perfectly and then I eventually upgraded my case a few years later.
Wondering why you didn’t went for this instead as this is the switch attached to the case button which goes bad.
There’s this guy who posts videos of making switching on his wife’s PC quite complicated. He does it for fun, but they seem to work.
The reviews and ratings seemed sketchy. I guess I will find out soon if I was right or wrong.
This should be bought from a local computer shop rather online. Costs max 30 bucks!
I am using this switch for atleast an year now, bought it for 10rs locally
