Pretty weird. I think I can just about hear the fan (something of a pain to look at the back with my setup) but it's extremely quiet, I wouldn't have noticed if I wasn't looking for it.

I have one of these on order. This kind of "standby" consumption is really not acceptable in this day and age...

bitseeker:
Hopefully, it's just a firmware change. It's not like the supply has an OCXO to keep warm. ;D

alm:
Maybe they did it to reduce boot time? But I agree that for a bench supply, that unlike a system power supply is usually only used for eight or so hours per day, this is ridiculous.

~92kWh a year, for me about EUR 20,- extra costs. What is about 8% of my total consumption per year for my whole house.

I'll talk to that team and see what they say about the standby power consumption. If it's an issue, you can always run a hard switch with a power strip.

Daniel, just checking in - was there any update on the team with regards to the power consumption issue discussed earlier in the thread? TIA!
