I'm not going to lie here that's fairly impressive given its size. Its probably the best ITX board for the 9XXX series I don't think it deserves a 2/5 just because it cant support one of Intel's ridiculously power hungry CPU...

I agree. 2/5 is pretty brutal of a rating considering the board runs well with everything but the 9900k; and is loaded to the gills for its size. I wonder if Toms contacted Supermicro to see if there was a bios fix, or something similar? Supermicro is usually known for exceptional quality motherboards and one of the go-to brands for servers.

Update: I reset the firmware after writing the article, booted up, started Prime95 small-FFT's, and the system did a hard reset (overcurrent protection). And you still want something higher than the middle score of 2.5?

It would probably have gotten a 3 or 3.5 if the 9700K were Intel's top CPU, but what we're really looking at with this board is Z370-class power regulation on the Z390. We're assuming the reason Intel delayed the Z390 is that they wanted to get manufacturers to support the power specs of the 9900K. After all, the H370 and B360 are based on the Z370, and the derived chipsets were released first for a reason.

Moreover, if you look at the power consumption, it looks like this board's biggest power shortcoming could have been addressed in firmware. It shouldn't need this much core voltage to run a 8C/16T load on the 9900K at 4.70 GHz.

Well Blood considering what Crashman stated, that's probably a no. Considering it can support a 9900k is impressive for what it is. Id like to see what the board is able to do with updated firmware. But going to be honest people are probably not going to be looking at serious overclocking in a ITX computer. I see the use of this more as a mobile work station and side gaming computer than anything else.

I completely agree on the use. HTPC, mini work stations, portable gaming, and micro servers are the main uses for Mini-ITX. The NUC, Mac Mini, Brix, and micro servers in general are perfect examples of those. It's almost crazy even thinking of something as powerful as a 9900k in something that small; but it is an option now. I'm guessing Supermicro is focusing on the server side of things given their pedigree.
