I bought this in the hope I could make it work with my Xbox One that I use for my video streaming. The stock PSU uses a 12V and 5V line but is quite noisy due to its fan and is an SMPS so probably quite noisy period. Another Second hand bargain at £170

I bought and XBox one PSU plug from ebay and had to DIY wire this one. I have the 5V and 12V output grounds wired together and all seems to work fine. Though Damn does this unit get hot. 40 degrees plus case temp. Class A amp users will probably tell me thats mild.

Result? pretty much the same as the other Linear PSU reviews. Decreased noise floor, sound more relaxed. And the picture, brighter, clearer, smoother. Even the wife noticed the picture and she rarely can with audio changes.

The HD Plex? I paid £170 for the 100W version second hand on AOS (close your ears)

New, they don;t do the 100W anymore but have 200W and 400W versions https://www.hdplex.com/hdplex-fanless-2 ... evice.html

It is not a rip-off but it is still a lot of money. I think I am happy with my £40 Chinese one.

had I have discovered your chinese one first, I think I would have tried using a 5v and 12v variant of those. Though I'm not sure how 2 seperate PSUs would have responded to me tying their output grounds together?

that said I don;t see chinese guys doing a high enough current 12V version. Only seems to go 2 Amps rather than the 7 Amp of the HD Plex

Technically the stock XBox PSU claims 21 Amps, but seems fine on the HDPlex at the moment

you're sure? XBox One has a bit of a rep for being a power hungry bastard.

The amps you are talking about is an electric fire. If the xbox was drawing that much current or anywhere near it you would be heating your room.

I didn't say bigger wouldn't be better, I don't know it depends on how they use it, what I said is you don't need it. It is all about common sense and practibility and reality. It would be pretty daft putting a £5 DAC with a £300 power supply, where as a £40 supply makes sense.
