How would I go about getting an Xbox 369 E Power supply.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today Primemedusa8625

As Microsoft doesn't sell now Xbox 360 and Xbox one accessories.
You may need to get the power supply using a third party seller like amazon, best buy, aliexpress etc.
Or if you have close a local video games store. Probably they will have it too.

If you have further questions feel free to ask
Greetings from another Microsoft user!

I also have a loud power supply, although I wouldn't say mine sounds "like it's about to explode". Instead I'd say mine sounds like a laptop fan going at max, which is much louder than the console itself while playing Forza 5. According to the "About the
Xbox One Power Supply" page (support.xbox.com/.../about-power-supply) the fan speed changes as the power supply gets hot. Mine does not, the noise stays constant
even after the console has been off (instant-on off) for upwards of five minutes. This suggests that either my power supply gets hotter when the Xbox is in standby than it is supposed to, or my power supply is not correctly adjusting to temperature. I'm leaning
towards the latter, since the power supply feels only slightly warm.

The "About" page from above does suggest plugging the Xbox into an outlet directly instead of plugging it in to a power strip. I've done this (in fact I'm typing this in my bathroom right now because that's the least taxes circuit in my house) and it's working
just as hard as it was in the living room, even after 5 minutes of standby.

Anyone have any suggestions, or know how I can go about getting a replacement?

Thank you. How about the physical side of it? Would I simply need to get a new power supply for both the 360 and One?

It's only the power supply that should need to be changed for the correct voltage; the job of the power supply is to step down the voltage from mains to console and convert the AC supply to DC, so that all consoles (in all regions) get the same voltage regardless
of the mains supply.

Get a new power supply correctly rated for your current region and it should all be fine.

Here's some more information on the power supply, but ultimately it's just a case of getting the correct power supply and you're good to go:

Hey there Corona!

We always recommend using a power supply from the region that you are using the console in. For more information about the power supply unit, check out our
Xbox One Power Supply support article.

I would suggest getting a power supply unit specifically designed for your region to use with your console. Let us know if you have any other questions! ^_^
