Just bought a GW-Instek GPP-4323 power supply-First impressions etc.

Well it cost not to much, R&Spricing are off the charts.
Not much choise left.

If china invades taiwan first thing they do is downgrade the GPP4323 to fixed amperes on the extra channels.

Nope, first thing they'll do is claim TSMC as a Chinese "asset" and "claim" China invented all the sub-micron semiconductor technology :o

GW price is reasonable.
Like R&S, Keysight is very expensive too :-\
Best,
Jan Audio:
By the way 2 of that other brand are more expensive then.

Bad design, same with the Rigol.
Edit : me happy GW fanboy.

Yes aware and we don't use the 5v section for any critical work, always for critical use the two variable voltage and current limit sections. We have 3 SDP3303X-E and they are good down to low voltage and currents as mentioned on those 2 outputs. One unfortunately isn't usable because of the current limit offset mentioned caused by my improper calibration, which makes for a risk for critical use and not acceptable to us.
GW seems like a good alternative, we'll definitely be looking at those for any future power supply needs.
BTW not a bad design by Siglent, they chose a simple linear regulator to keep within a cost budget....likely why the GW costs more ;)

Siglent 3303C has current limiting on 3rd 5/3.3/2.5 volt output.
