Would anyone happen to know of a decent 12V 5amp 5.5/2.5mm laptop power supply/charger. It's for a Qotom mini pc. It came with a Dajing supply which feels cheap and nasty. The only one that I could find that I recognised the name of, was a Channel Well Technology branded one (think they are a OEM for a number of branded ATX power supply's, like Corsair).
