That mb appears to have 8 channel audio on the backplane (7.1) and maybe another stereo header for the front panel headphones? That would make 10 channels in total which fits…
My gut feeling is they didn’t put 20 there in case you scraped one off. But likely the others will have enough leeway to cover for it. If the power rail gets stressed enough, it might well fail sooner than it would have.
Paralleling power metal-oxide semiconductor field-effect transistors (MOSFETs) is a common wayto reduce conduction losses and spread power dissipation over multiple devices to limit the maximum junction temperature.
It would also provide redundancy in case of a failure—if you had only one, and it failed (or was scraped off by an over-enthusiastic GPU installation), you would probably not be going to space today.
Yeah, I was being trite but still there is a reason. Idle doesn’t mean doing nothing. Perhaps it’s obscure, perhaps as impenetrable as some combination of machine state and number of milliseconds since 1970 being an even number. But you could try to track it down.
And sometimes the easiest thing is to reinstall from scratch.
They’re also rapidly making their way and taking a long time.
