Modern G4 Cube PSU replacement?


Nice! If only we could find one closer to the stock PSU it'd be perfect. Would be nice to be able to power ADC displays also. I think I'd probably be most comfortable running it on the 110 just for some headroom.

This is the same series, but 165W instead of just 80W, which is pretty close to the 205W of the original. At $196, it's a bit more than twice the price of the 80W model, but you might find that an acceptable tradeoff for the overhead.

The new Apple USB-C power bricks for the M1 Max / Pro laptops are 28v @ 140w. This is more than enough to run a G4 cube (which is not using an ADC monitor). Older USB-C adapters may be sufficient in some circumstances but I don't believe they have sufficient wattage / headroom for spikes.

The hard part is getting a USB-C connector adapter that's rated for 28v @ 140w because it appears to be a new addition to the standard. However, once an adapter is available you would basically end up with a very short adapter with USB on one side and the G4 cube plug on the other. Sounds dreamy.
