No disrespect, but Cost arbitrage?? is that a thing?
Comparing two costs and the return from each is part of a investment return, not really arbitrage... just saying....

In the situation where you have to choose between buying an expensive 1200 W PSU or one small PSU and one other small PSU later, it can be more costly to go for the cheap small PSUs because your rig isn't running at 100% while you expect the second one.

So you arbitrate between two costs: the premium of the big PSU or the time while you don't make profit with your cards (which is an opportunity cost).

Because running 3 cards instead of 6 will cost you $10 a day.

I'm not following that, how does that work?

3 is less than 6 Grin
