Here’s a Dell X300 that was being thrown out.

No, it looks like he just linked the wrong reports for that row. If you get the correct report by guesswork, it does show that for 230V it had the 80% efficiency. I don't know why I'm obsessing about this or why it changed.
Scraping Cybenetics' reports for 20W efficiency ratings and I'll admit that I have no idea how Wolfgang got his numbers for that spreadsheet. If you just look at the report on Cybenetics' site, they don't match what he puts here. For example, the MWE Gold 550 V2 is 70% at 20W but he says 80%.

PSU Low Idle Efficiency Database by Wolfgang's Channel
Google Docsbuilding a NAS on the tightest absolute budget right now. Case and motherboard combo are collectively $100. Motherboard is mini-ITX with 16gb and an i5-6400 and the combo is documented in hardwareluxx as idling around 12w. Then I'm gonna pick up a pico PSU and brick for hopefully ~$40. Then I'm gonna smash all of the hard effort by spending twice the amount on 2 12tb hard drives at about $320 total. So my "budget" NAS comes at around $450. This is for a 3-2-1 backup so no RAID.
