I just wanted to comment and say I'm running the Mean Well 200w + a cheap Realan 250w power board from Aliexpress for my 2400G APU build. Although my B450 motherboard has an 8 pin EPS connector, the Realan power board just has a 4 pin EPS connector. I just did a 90 minute stress test yesterday with Prime95 and Furmark and, although both power boards got hot, I saw no issues nor throttling of CPU/GPU clocks due to insufficient power delivery.I am currently just using an ATX power supply with the machine right now. The plugs on the 12V plug-in board prevent it from plugging in. The motherboard won't require the 8-Pin EPS connector but the APU/CPU might. The 8-pin EPS connector is absolutely necessary for the Ryzen 7 2700X but probably won't be for the APU at stock clocks. APUs can still pull a fair amount of power though.
Thanks for the heads up. I may just do so. Had I researched the Mean Well EPP power supplies sooner, I would have gone with a Ryzen 5 2600 or Ryzen 7 2700 and a RX 560 AERO ITX as that would get me near 200W and the EPP-200-12 is a 2" x 4" board. The entire build could be in a slim, console style instead of whatever this may turn into.
Note: a 4 pin to 8 pin adapter would not matter (I have one sitting in a box but chose not to use it as it takes up space in the case), as the same power draw is going through the 4 pin connector either way. I doubt the connector on the motherboard would be limiting factor.
