I rewired my ATX power supply breakout board so that I would have ready access to the fuses. Probably gonna blow a few of those! The fuses are 5A 250V fast blow (F5A250V) so I can’t draw more than 60 Watts (at 12V). You can see in the previous post and the picture at the bottom of this post that the terminals used to be connected above the fuses, impeding access.
I made three power cables today. Blue for 3.3V, Red for 5V, and Yellow for 12V. I used 4mm lugs and bolted them to my ATX power supply breakout board. So now I have some handy power rails on my bench powered from an old computer power supply.
Today I confirmed I can successfully power my Riden RD6006 power supply with this 19.5V AC adapter I picked up from Amazon. Big thanks to my mate Rick over on the EEVBlog forum for his help with this one.
In this video I use a 100W 6Ω resistor to test my Riden RD6006 power supply at various voltages from 1V to 18V up to a maximum power of 54W.
I should note that in this video I tried to draw 54W of power from the power supply, but the power supply is only rated up to 45W so I probably shouldn’t have done that, and won’t have any reason to ever do that again, I was just testing the maximum. So maybe don’t do that at home. :)

So I have one of these FNIRSI DC-580 buck-boost power supplies. It seems to have an CH340N USB to TTL serial port IC attached via MicroUSB, so might like to figure out how I can program that.
Got myself an XH-M229 board so I could repurpose an old ATX power supply. Apparently it’s suitable to use 1 amp fuses. Gonna send the 12V rail into my RD6006W bench power supply.
