Again you promoting and defending trash PSUs. In bench PSU efficiency is no so critical, we often use even linear PSUs. What's wrong with BJT is guaranteed subpar efficiency / high heat dissipation.
Yes, I have literally dozens of them without problems.
I use them literally for decades including several small
PSUs for bench work - all half-bridge design - all BJT based
I use HIGH COST PFC based ones in HIGH END PC GAMERs
where the cost literally explodes any budget.
A TRUE SINE WAVE INVERTER au pair with that ATX is also required
and considering benefits - IMHO they do not worth the money.
For the record: I AM NOT "PROMOTING" garbage.
Stop saying such shit
I am putting simple facts. Where they are not needed
those expensive solutions are expensive crap
My bench uses 5 HALF BRIDGE BJT based PSUs for decades
daily based - nothing wrong with that.
SOHO and POS give a shit if 70% 80% or 90% ratings
they care about monthly TOC (ownership cost)
Me too. I give a shit if 80% plus gold or shit.
I care about total monthly cost
