I’ve only had my IC-7300 for a day and am using the Meanwell LRS-350-12: https://www.amazon.com/dp/B07VTLJS18/ref=cm_sw_r_cp_api_glt_fabc_QTFBY1TEYESP50YA7546
It seems to be working okay, and I haven’t noticed any RFI issues compared to receive on my SDRs. I’ve seen reports of a few others using this power supply. When transmitting FT8 at 50w, I notice the fan on the PSU kicks on after a few minutes, only during the transmit cycle.
I 3D printed a cover over the screw terminals, and am using a C14 socket with a switch.
