Wondering if anyone has come across this motherboard before: "Kobian PVM890M 1.0"

I purchased a number of clone PC's in an auction for schools in Africa, and some of them have been diagnosed with Faulty Motherboards, and these PC's are fitted with this motherboard.

I would like to replace these motherboards, using the same Processors and Memory that came with the PC's. I am told the Processor fitted is "Socket Type", and the Power Supply that goes on the motherboard has "10 pins". Could anyone help identify the type of MotherBoard, which replacement type should I be looking for, and if anyone can point me in the direction of a source of supply for this,

Grateful thank you.

Short, practical plan that builds on ’s goal and ’s suggestion but avoids needless disassembly.

First — identify precisely without guessing. If the PCs will boot, use a system utility (CPU‑Z, Speccy or the BIOS/UEFI) to read the Mainboard and CPU fields; that will usually show maker, model, chipset and the memory type so you don’t have to remove the CPU. (pcworld.com)

If a machine won’t boot, open the case (power off and unplug first) and photograph the board top and back: look for a printed model string, BIOS sticker, chipset markings, the CPU socket code and the RAM slot keying. DDR generations are deliberately keyed and aren’t interchangeable, so confirm DDR vs DDR2/DDR3 before sourcing parts. (crucial.com) Driver/scan databases and archived forum posts for “PVM890M” show examples tied to Intel LGA775-era Pentium dual cores (E2140 appears in at least one reported system), which suggests many PVM890M machines use older LGA775 boards and DDR2 memory — use that as a starting search term. (forum.chip.com.tr)

Check the power connector carefully. Some OEMs used a proprietary 10‑pin motherboard connector; those systems usually require the original PSU or a purpose-built adapter and should not be jury‑rigged — using random cables risks frying the board. If the PSU is proprietary, either source the matching OEM PSU/adapter or look for a compatible donor motherboard that uses a standard 20/24‑pin ATX header. (cpumedics.com)

Quick diagnostic/workflow: (1) try a minimal boot (CPU, heatsink, one known good RAM stick, onboard video or GPU, PSU) to see if it POSTs; (2) inspect for bulging capacitors or physical damage; (3) swap in a known‑good PSU if available; (4) photograph parts and list exact model/socket/RAM when contacting sellers. These steps narrow whether you need an identical Kobian board, any LGA775 + DDR2 board, or simply a replacement PSU. (blog.silverpc.hu)

If you want, capture CPU‑Z screenshots and clear, close photos of the PCB and post them when asking sellers — that makes matching replacements a lot faster.

hi,sounds really old ,but im thinking maybe on e-bay ,the power supply sounds like AT, the socket type ,is not enough to go by as they all were refered to as socket type ,then a number like socket "A", socket 5,socket 7,super7 and so on .
you would need to take the cpu out to see the type written on the socket .my humble opinion is i know you mean well but it seems like a wast of time and money to try and fix the broken ones ,hope you didn't pay much for them,

Hi,

Thank you for the reply,

No, didn't pay much for them, but in Africa noting is thrown away, and it seems a shame to throw these units away. Also, import duties are so high, that it would cost a lot to import new computers, but relatively cheaper to fix these with new motherboards.
I will have the info you refer to checked tomorrow, see what is written under the CPU, and post here.
Thank you again

Power Supply that goes on the motherboard has "10 pins".

do you mean 20 pin, like 2 rows of 10 each, these computers may not be as old as im thinking they are,same model ,but show as mercury and i think Kobian and Mercury are one in the same , so these computers are relativity new then ???

like this one .
