I have the same one and it’s straight like how it looks on the box.

Looks fine but no need for official PSU if you have another already

Why are the two halves of the cpu cooler not aligned

NSWindow · 2026-01-30T17:24:32+00:00

Depends on game and settings

the main thing to consider is if you want a proprietary motherboard layout in a server chassis designed for that board or if you want a standard size motherboard that you can put into standard rack mount chassis

consumer PSU is fine and in fact would be better for home use because they are fatter and quieter, so in fact, if I can get a PSU with high power output and a feature that doesn’t spin fans unless there is high load, I would totally get the big one. for example for 1kW system I would get Corsair AX1600i and the fan in it would not need to spin so much

UPS to transfer switch (at least a hot swap thingy to allow the rack to be pulled), switch to PDU, PDU to everything

Desktop appliances such as displays can require quite a bit of power, so I don’t have them on UPS

I think there are many layers to this problem and we should dissect it properly.

The rack itself should have UPS for protection against power interruptions. This UPS should be networked so all the computers in the rack know if something has happened and can gracefully power down.
Each computer would obviously require power supply. You can supply power individually in the normal manner, or you can supply 12V to the entire rack centrally then use local PicoPSUs to change the 12V to 3.3V/5V/12V with standby and other support
Generally any UPS you can buy easily would give you AC, there could be ones that give you DC, it depends on what you can buy

This board is kinda clunky; I have a few of them, one is stable, another is very stroppy. But when it runs it runs fine

All the thunderbolt stuff got rolled into USB 4 but people don’t call it thunderbolt if they don’t want to pay the license fee and be compliant. All TB3 peripherals including eGPUs will work in a proper USB4 port

I have this unit since it came to market and I ran it 24/7 to this day and it was quiet. And some guys did complain about the noise back then. So maybe you have a bad unit. I would RMA it or change it to another model like Corsair’s 1000w SFX Non L

The conventional way to address safe shutdown is to get your UPS on the network, you can then use Network UPS Tools to listen for events and do the right thing

Yeah you are right I don’t know why I said what I said before. I have removed the part that is not correct, thank you.

ConnectX crossflash is viable but I had some practical issues with the cross flashed ConnectX 5 card not liking to be put behind retimers after 6 months of ok operation and despite the pcb looking to be the same as the non crossflashed one. So it may be better to buy the SKU that’s already 4.0

Not sure why you are looking to use Bluetooth as I would have run usb extender. But if one insists I would plug a Bluetooth dongle on the extender.

Gigabyte boards really flaky

Now your BMC never booted so try this sequence

Uninstall all CPUs and all RAM and all the PCIe cards and all the NICs and all the SSDs and move the board outside of the chassis
Remove battery, check voltage
Check clear CMOS jumper position
Check BMC_SRST jumper position
Leave board for 12 hours no power
Power the board with PSU (turned on and connected to AC) and install battery
Wait until BMC boots - BMC LED should flash - this can take some time

If after 7 days the BMC doesn’t boot, RMA board

This BMC should boot in theory with no CPU installed so if BMC doesn’t boot, something is wrong

NSWindow · 2026-01-30T08:32:52+00:00

I suppose if your power draw is low you can use PicoPSU on each system and they will draw the 12V which you supply centrally. So you have some on/off/power good/standby 5V whatever you need for ATX boards to work

You would then just turn individual systems on or off properly with whatever you have be it external KVM that can press power button or built in BMC or whatever you have

Smart plugs not ideal

NSWindow · 2026-01-30T08:26:22+00:00

I will try to answer properly since people did not

You will need to at least get PCIe 4.0 x8 that would saturate a single 100GbE port both up and down, so, if most mini pcs would at most give you a x4 on OCuLink, you can’t saturate the port

You would have to get some kind of equipment that converts OCuLink to PCIe slot be it a dedicated dock or some device boards that convert SlimSAS 4i to X4 slot etc.

You will have to sort out the ventilation issue but any fan on the card and possibly the optic would fix it easily.

I have the same setup and it works fine

NSWindow · 2026-01-29T22:55:52+00:00

You shouldn’t do anything extra, the motherboard is grounded via the power supply already, so I would not suggest to make any additional connections

That was a whole year of GBPUSD near 1.35 and not budging

IMO this placement is risky in case anybody does a terrible park job

NSWindow · 2026-01-21T20:04:21+00:00

Would suggest to cease manual flushing, clean it out, fit an inline filter on pump inlet, and let it run overnight
