I am not even sure the power supply I got with my unit is a genuine LiteON or a rebranded something else. There is no reference online for the part number I've got (PA-1480-5M04), also the sticker (see my
post on the previous page) is significantly different from other models I can find online. I've only found a sale on taobao for what looks like the same psu I've got.

Possibly an OEM part?
looking for similar models, I've come across the PA-1041 on their
site, which is a 12V 40W device rated at 88% efficiency. I do have a variable power load, I'll try mine with at a few different current levels.
Both my switches also operate on 12V power, so I could theoretically use a single power supply instead of having multiple bricks in the network rack. Meanwell does make some really nice devices, have a look at the HEP Series. The 100W version does does offer a 92% efficiency and 98% power factor at 12V (part number HEP-100-12A). Only downside is the price, lowest I've found it is 90€. A more reasonable (but still solid) choice could be the HRP-100-12 wich is still 87.5% efficient, active PFC, 12V 100W at around 50€.
