Las Vegas' dystopia-sphere, powered by 150 Nvidia GPUs and drawing up to 28,000,000 watts, is both a testament to the hubris of humanity and an admittedly impressive technical feat | PC Gamer (www.pcgamer.com)

28,000,000 watts

That's usually written as 28MW. I know some Americans don't like metric much, but one of the points of metric is that you don't ever need to write that many zeroes - you just need to use the right prefix (kilo, mega, giga, tera, etc) on the unit.

True, but 28 million watts really puts things in perspective when your average PSU is less than 1000w.

Exactly. This is literally a PC gamer article. Writing it out like that really puts it into perspective for the average reader.

[–] dan@upvote.au 7 points 4 months ago (1 children)

That's true.

average PSU is less than 1000w

Unrelated but I wish it was easier to find lower-wattage PSUs. My local PC store doesn't have anything under 650W. I know modern GPUs use a lot of power, but not all PCs use a GPU! I have a home server where 400W would be more than enough, yet the smallest I could find was 550W, in stock from just one manufacturer (Be Quiet).

I mean, it should be fine, just because the PSU can provide more watts doesn't mean the system is actually using that much power. I have an 800w PSU in my gaming rig, but its average load is only 240 - 320w during gaming (I've measured it by powering the system with a portable Ecoflow battery).

It runs fine, it's just less efficient.

Where are you getting this from? Intuition?

I think the quiescent current and losses are less in a well engineered psu.
