    20 pin power supply 24+4 pin motherboard

    Currently I have a 20 pin pico PSU wide band DC-DC 120w power supply for my motopc. I have that in a D510MO motherboard. I am looking at the intel D525 board for various reasons and noticed that it has a 24 pin atx connector just like the D510 but it also has that 4 pin CPU power connector. I was wondering if there is a solution to make that PSU work with that mobo?

    My Zotac has the 24 pin connectors. The PC works perfectly without the 4 pins connected.

    Like HiJack said, you don't need anything but the standard 20 pin connector to power your motherboard.

    If your talking about the 4-pin atx 12v connector and not the extra 4-pin plug on the 24-pin EATX PWR plug. You will need that(4-pin ATX12v) plug so the motherboard will boot. That plug supplies power directly to the CPU and will not work without it. You can get away without connecting the extra 4-pin plug on the EATX so you just have the 20-pin plug connected. But you will need a 4-pin(2x 12v+ and 2x 12v-)plug for the CPU. You should be able to buy an adaptor to fix this or make one yourself. With the 24-pin EATX PWR plug, The extra 4-pin is for extra pwr for the CPU if it needs it. But in most cases especialy with carpc's your pc wont need the extra power.

    Be aware, that the picopsu wide input requires 12-15V input That means if you hook it directly to an automotive electrical system you will burn it, and/or anything attached to it up. Be sure you are hooking it to a regulated 12V source, not raw automotive power (Which is 8-16 or so volts, depending on other factors)

    This is the PSU.

    I found a solution that converts a regular 4 pin molex connector to the P4 CPU power connector

    So as far as the PSU, it takes 6-24 volts DC in. and it is installed into a sport bike. I will be throwing up a V2.0 install when I get all the new parts in.

    You are correct, I was speaking of the P4 connector that is seperate from the 24 pin connector.
