Mame cabinet power supply unit noise?

[ninja2bceen]

Hi I don't know much about psu's other then my computer and cabinet both have one I'm wondering if the noise is normal or if it needs replaced. Listen to video it's not bad but a little high pitched

What is the power supply in the cabinet connected to?

[ninja2bceen]

It's plugged to the wall and a surge protector which the surge protector has marquee light, computer and monitor

I can take pics of the inside. What you see is the wall and the outside of the cabinet. To turn on my cabinet I have to hit that little black switch on the psu to allow power which start the sound

That's a normal amount of noise for an average PC PSU. You have three options:

1) live with it

2) buy a premium PSU - will be more quiet, but cost a fair bit

3) renovate the cabinet to have the PSU be inside the unit itself, providing noise insulation. If you do this, don't forget some ventilation holes!

So you run from the wall into a power supply, to a surge protector, to your PC power supply and other connections? If your PC already has a power supply and you're using a surge protector anyway then it doesn't seem to me that you really need a 2nd psu for anything. Maybe you could just bypass it or remove it. Less power drain, less noise, less heat, less parts to break...

On my cab I have my PC, Monitor, sub/speakers, LEDS/marquee all plugged into a PC master/slave control surge protector. That protector is plugged directly into the wall from inside the cab (no secondary psu). I hid a normal arcade button on top of my cab for a power switch and wired it directly to the power button control on my PC's mother board.

So to turn it on I simply reach up and press that button, which turns on the PC, which then tells the surge protector to turn on the monitor, lights, speakers etc... Everything turns on in sequence with a single button (while playing the Pac-Man game start music). Hit the buton again and it shuts everything down in order, PC closes all programs and shuts down correctly, which turns off the monitor, which then shuts down the lights etc... (while playing the Pac-Man death sound effect, Ha!)

Works perfectly awesome

Thanks guys, yes I purchased a cabinet and really had no idea about the power supply thing. I'll take pics for you all to be sure. I've thought about it myself really. Yes I have a pc with speakers plugged into it. The pc is plugged in a surge protector. A monitor is plugged in surge protector. What would be the point of that power supply mounted to the cabinet?

Exactly. If you pick up one of those PC control surge protectors like I'm using you don't need it at all.

[ninja2bceen]

Here is the inside. So why was it mounted there by default? I purchase this one... that's the power supply and the white cord is the surge protector

Here is the surge protector

I have a trackball that lights up blue but don't have ledblinky. I also have a button for a single to turn on everything but I don't actually have anything hooked up to it but the cabinet has a button ready. Sorry noob here discovering what I have

Button on the back not hooked up to anything

Power supply was probably there for running a standard monitor + Jamma/Neo-Geo board type arcade setup. That's my guess.

That button is cool. Should work like mine if you can connect it to a PC motherboard pin type wire and if you can figue out where to plug it in on the motherboard.

I just followed the wire from the power button on my PC case.

[ninja2bceen]

Can you tell me more how I would get my pc hooked up to that button? That button is hollow as if I need to put a button in it? What do I plug up from there? Got a tutorial?

I can take pic of the cab and monitor. I don't think is a standard monitor. Do out of the box psu have the nice wore connections already? It's pretty organized it looks like.

It also has a mini fan at the back of the cabinet, it's mighty loud. Are their fans that are quiet? It just pushes the air out of the cabinet itself. Maybe I should make vents on the top instead?

Your ultimate suggestion is just unplug the psu and plug in the surge protector instead? Psu serves no purpose with the surge protector?

Well I just hooked mine to a normal arcade Happ button. just two wires I connected to the button and then connected those wires to the power power button pin clip thingy like in this pic.

The only Power Supply in my cab is inside my PC case and the only fan in my cab is inside my PC case. The back, bottom 3rd of my cab is open to the air so I don't need additional fans or cooling.

My setup is:

Wall Power > Master Surge Protector > PC plugged into "Main Control" plug on surge protector > Monitor, Margquee LED's, Speakers/Sub woofer, Backup HDD, USB hub etc... all plugged into the "slave" plugs on surge protector. A couple other things plugged into the "free" plugs on surge protector.

That's it. It runs so quite that even with your head down near the back you can barely hear it.

Here's some pics of mine. Lame that Onedrive pics can't embed.

Button inside cab and wired: http://1drv.ms/1H6Sfkh

Wires run all the way down and into my PC case. The yellow on the left is where I spliced the button wires to the motherboard/pin connector wires.: http://1drv.ms/1Gf69eg

Then the pin connector plugs into those bottom center pins on my motherboard. Of course it has to be the correct pins: http://1drv.ms/1H6Suvs

I think I'm going to need a you tube video. I'll do what you did then. What the point of a psu outside like this? Does it just act like a surge protector? I guess I'm confused of the original purpose :-) thanks

My guess is the original purpose was probably to have it power actual arcade, real hardware. Such as Jamma or Neo-Geo arcade motherboards with game cards/carts, Arcade CRT monitors that don't just plug into a normal outlet, wired lighting, coin slots etc...

My real arcade machines both have a mounted power supply like that. But our Hyperspin machines use PC's which already have a PSU, so it seems to me to be redundant. I'm no expert though.

As for wiring your PC to a button there were topics about it at arcadecontrols.com I believe. I think I just googled something like "wiring arcade power button" or something.

Good luck!

Thanks man. Sounds like if I had a crt I would be asking how to turn it on. Very useful information
