proB (npub1f64…5rsj) 330W is crazy, my gaming laptop has a 230W supply. Is this for a workstation or a much newer machine that somehow uses more power at the wall as a laptop?
I recall GAN stuff being around $80 around when i got the laptop, too - mine isn't USB powered - so if inflation is correct a official dell 330W for $130 "feels" like a fantastic deal - those $80 ones were from aliexpress.
If i had to power a bunch of USB stuff i'd buy something like this, though. I like & use dell PSUs
