The chip might be one part... but now consider a dual-processor setup, plus fans, plus cards (RAID, multiple 10Gb/40Gb networking, GPUs for some loads, etc.), plus storage (e.g. a server with 12+ drives in it is pretty standard, nowadays NVMe is pretty standard but the internal storage is often still 12 x 15K spinning disks), plus a TON of RAM (the last servers I bought have 32 DDR5 RAM slots - 16 per CPU - and can take several Tbytes of RAM).

Plus PSU losses, redundant PSUs (again... never completely idle), etc.

Dual NVMe boot drives + multiple 10GbE SFP ports + internal RAIDs on the order of 10Tb is pretty much standard "small school / office" hardware for servers nowadays.

And then you have multiple of them, usually in multiple locations, and that's just your on-premise stuff.

The small school I work for has 10Gb leased lines.

Ha! The day I got the 3DFX and saw Quake II IN 3D blew my mind. How the world was in actual 3D. Seeing that effect for the first few times was so satisfying.

I still remember the first day we got Cox cable instead of Compuserve because I had been trying to download the trailer for Castlevania 64 from Ign64. I was floored the 30mb clip took 27 seconds instead of hours.

Then walking past my Dad’s office around 2am seeing SETI running on the Gateway p3 makes me nostalgic. Hearing the cpu make its noise, seeing the lights flicker off the walls from the modem…

Such great times!

A blade server I had used to pull 3KW under average load. Full load required 4 separate 13A 220V mains plugs. It would literally "dial down" if you only had 2 or 3 plugged in.

But even that just ran off four normal 13A sockets in two double-sockets that were installed in an office ring main.

Generally you don't have servers unless they're pulling power... or entirely idle. Even a redundant server is churning along doing everything the same, ready to take over at a second's notice if it needs to. 800-1000W draw isn't unusual for a single server, 1400W if it's being stressed (and all servers get old enough to be stressed, when you then start trying to pitch for upgrades).

Hell, I have network switches that individually pull 700W during operation (usually PoE switches powering phones, cameras and wireless points).

A small rack of basic networking equipment can easily max out two 13A 220V plugs (don't forget, you'll have a UPS on that, so it's only 90% efficient before you even start).
