Since I know this seems to be a very common issue for members here, and I'm not personally selling these... I figured I'd post it in here rather then the eBay sales thread in the Marketplace. It would probably go completely unoticed in there.
Someone is selling some 213w Sidecar Compatible PSU's on eBay, I sent him a message to verify the supported ampage on his just to be sure, and it all lines up.
His Response:Hey Graeme, I've been hunting down a PSU like this for a little while, and I think you've got what I've been looking for.
I just need you to confirm that the Ampage on the PSU's you're selling. It should say on its sticker. Something like this picture.
That sticker should look a bit different then what is on the PSU's you're selling, but that's fine. I've outlined in red what I need you to check, should be somewhere on yours :)!
I need you to check and confirm that it says
12V - 16.5A
5Vsb - 3A
Get back to me ASAP! Let me know if the PSU amps match the same as I provided. If not, what does it say instead? Should be the same however.
Thanks! If it's what I'm looking for, I know a few others who should be interested in nabbing a few off you too.
Not sure if his 203W units have the proper ampage lines though, so you'll have to pick up one of these fast ;o.It looks identical to your picture except the label is Microsoft branded and is printed "letter" style as opposed to "landscape." MS part number is X801405-003. Your picture shows the model number X801405-002. What I am selling says 213 watts,12volts, 16.5 amps, 5Vsb------3A. I believe that this is a later model number, DPSN-216BB A. These were made to be used in the Xbox 360 interactive demo units in GameStop, Circuit City as well as other locations. The extra wattage was, I believe, to compensate for the cooling fans in the unit's tower. Let me know if you need any further information. I have eight of these and 9 of the 203W units left. Thanks!! Graeme
Suprisingly I found the auction by simply searching Xbox 360 Power, and limiting only results for >$10 shipped(weed out the pointless unrelated crap). I just scrolled through the auction lists looking at the auction primary picture. I was actually very suprised to stumble upon these, seemed completely out of the blue.
tl;dr version - Some proper 360 PSU's to power a Kit + Sidecar are on ebay.
$24.04 Shipped for myself, I'd call that a deal. Guess it's time to throw the ATX-Energyzer monsters in the closet. Not sure if these are on eBay all that much, but either way, nobody here ever seems to have one to power their Sidecar anymore.
Good luck grabbing one,
PS:Thanks to Pikkon for the original image I edited and sent to the seller ;)
