  • 20 pin to 24 pin atx

    I have an M2 ATX power supply but my mother board uses the 24 pin connection.. i bought that 20 pin to 24 pin adapter..it works..but damn..extra wires for a small enclosure... any other way around that?

    I think M4 has 24pins. If you wanna stay with M2 ATX, I don't think there's any way around using an adapter

      Yeah, I figured as much. Only other solution I can see is to cut off the 20 pin connector and splice in the 24 pin adapter but that's alot of splicing and the M4 won't fit in my morex case, I think the M2 alone was designed to fit in it.

        Are you positive that you need all 24 pins? Most motherboards will run just fine with the 20 pin connector.

              The extra 4 pins are for an additional 3.3, 5, and 12V circuit. Atom motherboards definitely don't need that. I have a 510MO and it works just fine with the standard 20 pin connector.

                just try it. if it doesn't work, then it needs it.

                the asus boards that i have tried have not required it yet.

                  ok, does it fit only one way ..meaning the extra four pins left out are towards the center of the board or towards the edge? I mean I have my CarPC set up in the car but I was thinking to add an Intel Z-U130 4GB USB SSD for the operating system so I was just thinking if i can get rid of that extra 24 pin adapter it will free up some room and make it look neater...

                  also, do you have a high pitch whine noise with this board? I know its a ground loop problem, but the thing is, I used a pico itx board before and didn't get that noise, i didn't change anything of the wiring, just built this pc and put it in the place of the pico..

                    I did have a noise issue, but mine was due to a very cheap amp. I had noise with my DCDC-USB and my Opus. I put in a ground loop isolator (a power filter in-between my power distribution block and my computer) for less than $10 that fixed the problem. Once I upgraded my amplifier, the noise disappeared.

                    Automotive power supplies are notorious for introducing noise. Sometimes there just isn't anything you can do about it other than use a filter. I read an interesting post somewhere (it was in the last few days, but I don't remember the forum) where a guy tried six different amps, all from excellent companies, and three of them had noise and three of them didn't. You can try a different ground location, you can try running a ground back to the battery, you can try grounding your RCA cables, but if that doesn't work just put in a filter and be done with it.

                      As for amp, I am using an MTX amp.....I was trying to avoid the ground loop isolators. I've used them in the past and they do work but its one less thing to deal with..thanks Keg-o-beer!

                        you might need to ground the mounting points on the motherboard if you mounted everything on wood, or plexiglass. also, is everything grounded to the same spot?

                        changing equipment is enough to cause a ground loop that the old system might have covered up.
