Comment on Ask HN: How much electricity does a WiFi router consume?parent

Comments

Thanks for that. I rarely take much notice of PSU's, other than desktop computer builds, where the received wisdom seems to be aim at using around, or just under, 1/2 of the spec'd capability of the PSU.

Seemingly this is optimal for efficiency of the device, and I've never really thought about how or why this claim is made -- opinions are consistent, pricing is rarely significant, etc.
