Unfortunately, as of this time, Microsoft does not sell XBox One AC adapters. XBox One adapters are almost always single voltage. I'm an expat who has bought a US XBox One and would like to use it in Europe. Since no one can source an XBox One EU adapter from Microsoft, the only other source are Chinese knockoffs that are underpowered.
Microsoft US Voltage AC Adapter Specifications: Input: AC 100~127V 4.91A 50/60Hz Output: DC 12V 17.9A (215W), 5Vsb 1.0A
Chinese Dual Voltage AC Adapter Specifications: Input: AC 100~240V 2A, 47~63Hz Output: DC 12V 10.83A (130W), 5Vsb 1.0A
Can I combine two underpowered adapters, wired up in parallel, to create one full powered source? For both 12V and 5V? What are the risks? Any other options?
There's some hope a knockoff will work as is. AnandTech has tested the draw from an XBox One and found that it only draws 119W max, and as low as 69W otherwise.
Edit - 16-Dec-2013 Thanks for the suggestions about using a stock power supply. Looks like any PC ATX power supply will provide the proper volts at more amps than the knockoffs. They are often dual voltage too. For example:
This ATX power supply has +12V@18A on pins 10 and 11 (yellow wires) and +5VSB@2.0A on pins 9 (purple wire).
How do I hook up the ATX power supply to the XBox One's two prong connector?
(1) Should I bundle multiple ATX +12V wires together or can I use just a single wire?
(2) I assume that ATX +5VSB amps, being double the XBox One adapter, is ok to use?
(3) I'm making an assumption that the XBox's dual prong plug needs +5V and ground on one prong, and +12V and ground on the other.
(4) I can probably wire the XBox One plug to an ATX female to mate with the ATX power supply.
(5) What are the caveats and am I missing anything?
