Way too much. The Nvidia P40 I scavenged for my homemade AI server runs at 120W (throttled down from 250W default) on its own. Then I’ve got two more PCs running purely as redundant firewalls with automatic failover, pretty unnecessary but if that’s not the sort of thing homelabbing is for then I’m going to keep doing it wrong because I find it fun. Then there’s the minecraft server, which is pretty beefy and also eternally running at max CPU because my niece is a monster who loves spamming spawn eggs and should never be allowed access to creative mode. And I don’t even have the two rack units of disk arrays I bought at auction powered up yet because they need 240V which I don’t have handy. I guess someone could do the math on what 48 enterprise SAS drives will pull if they need to satisfy their curiosity, I’m not sure I want to. I will hook them up someday but for now ignorance is bliss. All I know is it’s a lot, and there’s stuff I’m not even including in this.
