Just a reminder, a rule-of-thumb is if you're running a 'continuous' load (i.e. mining rig 24/7), you should never exceed 80% of the rated circuit's capacity. So a 20A circuit at 80% capacity is 16A or 1920VA(W)'s. It's part of the NEC code.

Like most rules, it's 'meant to be broken', but I thought I'd just throw that out there.

You don't break the rule when your PSU is specifically designed and guaranteed for continuous delivery of the specified power.
I've seen one recently...
