Tell us about yourself!
I agree with nlkirchn. The power supply in the video is LS50-36, which shows at DigiKey as 3.90" L x 3.80" W x 1.40" H (99.1mm x 96.5mm x 35.6mm). The one in the link (which I just received today, so saw nlkirchn's post too late) is 79mm x 110mm x 36mm. Looks like a spacer or an updated case will be needed. :-(
Perfect! Thanks -- I should be good to go... whenever AliExpress cares to deliver. ;-)
