What voltage is the power input?
it iiiis aaaaaa.... RT8288A so that's a buck converter, input anywhere between 4.5V and 26V, and it's tuned with 2 resistors to create 5.0v. it's about 75% efficient or so according to the datasheet.
so luckily, 5V or 12V input PSU it really won't care. the caution about the 2 different plugs appreciated, but i have already done the part and i know it takes time to redo them and find suitable replacements and the suppliers and so on, and i'm not hugely keen on going through that again right now.
i think a good voltage range is enough to be getting on with: the PSU only needs to be 10W so i think we're good.
