Hello,

And what about the heat ?

Can I use EPower without a heatsink ?

Or a smaller one ? Did you test that ?

(I will use an EP without a chassis, only with the motherboard on legs,
I would happily remove the original EP heatsink if I can ...)

As I wrote earlier. Without a heat sink at a load of 2A on 5V power, the main stabilizer heats up to about 40°C.
A small radiator would be recommended just in case.

Ahhh ... sorry ... I swear I tried to read carefully ... :oops:

Is this case (2A, 5V power) the case of the EP ? Because 40C seems very OK to me ... that is nothing ... isn't it ?

(Is that 5V the input or output side ? Cause EP power supply output is something 9V or 12V ...)

The 5V is on output side. This is the maximum load for which the original power supply circuit was designed.
The manufacturer of the stabilizer chip recommends a small heat sink for better heat dissipation.
Better cooling will extend its durability.

Z80System want to use machine with CMOS Z80 and SRAM expansion. Less consumption than the original machine.

Of course you can try without a heatsink.
It's just a recommendation.

I will try both ... thx.

First I will try with the original heatsink,
but when I got to the fine tunning,

I will check this heatsink removal question as well ...
