It typically runs 120W idling, and 450W peak.
Not great power efficiency wise, but I have a Cron midnight shutdown and and S5 bios event powering it up on a morning (I could use wake on Lan but didn't see the point).
It was AliExpress, during sales, earlier this year, with discounts from playing games. I typically used to see much higher eBay prices.
A bit of hyperbole tbh, not everyone has the patience to do this but I was honest that this is what I got them for. The DDR shortage has pushed the current price up to $130 (?) or >£85 after all discounts now.
