How much power do older mainframes need (if they're actually even run)? (lemmy.world)

I’ve never worked with major enterprise or government systems where there’s aging mainframes — the type that get parodied for running COBOL. So, I’m completely ignorant, although fascinated. Are they power hogs? Are they wildly cheap to run? Are they even run as they were back in the day?

huge power consumption... very expensive to run. i have regularly had access to take these things, but its like wanting to take home an old steam engine. its huge, expensive and to what end?

ha, they are run exactly as they were back in the day, thats half the point. no one wants to pay to replace(rebuild from scratch) that system.
