The KX-U6580 CPU is an x86 CPU that is not from AMD nor Intel but from VIA/Zhaoxin. It is BGA and not socketed so I had to get the CPU and the motherboard together. This motherboard is very strange and was a bit difficult to put together a PC with it but I managed to do it. I found the motherboard on Taobao for 1885 RMB. It's just called "KX-6000-i" and there are no brand names written anywhere on the motherboard nor on boot and the BIOS is sadly rather limited. The only thing I can find mentioning who made the motherboard is "HJS" which I don't know what company that is.
The computer is NOT powerful by any means. This build was not meant to build a super powerful computer. The GPU in here is literally a GT710. It was moreso meant to just be an interesting build, a PC built with an obscure motherboard and CPU. Benchmarking the CPU it does not perform very well, my other PC with a third-gen i5 seems to perform a bit better. So I only put a GT710 in here for this to be a web browsing machine and not a gaming machine, although it can run some simpler games like Terraria.
I had some strange issues with this build that I had to work around.
1. The motherboard doesn't have a pin header for power except for a 4-pin CPU header. This is an issue because even if you plug in a 4-pin CPU header, the PSU won't even turn on without the motherboard connector plugged in, so you need an adapter to plug onto the motherboard connector on the PSU to trick the PSU into turning on in order for it to power the motherboard.
2. Since the PSU motherboard power connector is not plugged into the motherboard, the PSU will remain on even if the PC is turned off, so you have to manually turn the PSU off after shutting the PC down by flipping the power switch on it.
3. There is no PCIe slot on this motherboard. I had to connect a GPU going through the WiFi/Bluetooth card slot which is called an e-keyed M.2. slot and buy a mounting bracket thing to hold the GPU in place. It's a bit messy but it does work.
4. The GPU being powered on a riser means it does not receive power from the motherboard, meaning it remains powered on when the PC is shut down but the PSU is not shut down. This can cause problems with GPUs with fans as the GPU will ramp the fan up to max speed in this scenario which can get annoying. Luckily, the GT 710 does not have a fan so this annoyance isn't as big of a deal.
5. There is only one pin header for fan power on the motherboard and it's reserved for the CPU fan. In order to hook up the case fan I used a converter to convert the internal USB port into a fan power pin header. It works, but the case fan can't have its speed controlled.
6. I don't know why, but the motherboard always lets out a single loud beep when it boots. It gives some post codes on the screen but I have no idea what those mean. The motherboard did not come with a manual and came in a blank card board box with no writing on it. The beep may not even be a bad thing, could be a "success" beep since the computer boots successful.
7. The motherboard didn't even come with an I/O shield, I found online plastic I/O shields which you can cut to your motherboard which is what I ended up doing.
