N64 freak Posted August 1, 2017 Report Share Posted August 1, 2017 Finally found the time to test the Adapter PCBs i built to use an ATX Psu to power an Xbox. They are plug and play to easily switch between the original psu and an atx-psu.Might be usable for casemods or laptop builds. The adapter is built around the following basic schematic. It properly convert the Standby voltage from 5v to 3,3v and also shifts the power_ok and power_good signals to the correct levels. Also built a small version that can be used to build an extension cord style adapter to save some more space. Just let me know if you have any questions about them 6 3 Quote Link to comment Share on other sites More sharing options...

N64 freak Posted August 17, 2017 Author Report Share Posted August 17, 2017 Just an hobbyist who likes the xbox The infos for the atx adapter have been around for quite some time! Sickmods once sold similar adapters but there shop is closed so i couldn't buy one. Inspired by there design i drew up the shematic and layout around parts i already had here. 3 Quote Link to comment Share on other sites More sharing options...
Crazyembereks Posted November 8, 2017 Report Share Posted November 8, 2017 Nice! Will these be for sale? Could you post a link to an ATX PSU that will be optimal with this? Quote Link to comment Share on other sites More sharing options...
N64 freak Posted November 8, 2017 Author Report Share Posted November 8, 2017 @Crazyembereks If you want one just PM me! They are for sale just haven't posted them in my for sale section. You just need to let me know which revision xbox you got! This Adapter and the Xbox in general isn't too picky about the ATX PSU as the xbox doesn't draw more power than any pc. Any ATX PSU even the smaller ones for office PCs should be sufficient. The minimum specs are: (Taken from a 240v V1.4 Foxlink PSU) 96Watt power output +5V with a rating off 13.2A +12V with a rating off 1.2A +3.3V with a rating off 4.8A +3.3VSB with a rating off 0.045A If you are unsure if your PSU is sufficent just let me know the brand and model so i can take a look at it! For the 3.3vsb you are looking at 5Vsb on the ATX psu the adapter does do the conversion to a 3.3Vsb voltage! So don't get confused you won't find 3.3vsb on an ATX PSU 1 Quote Link to comment Share on other sites More sharing options...
daniel Posted December 22, 2017 Report Share Posted December 22, 2017 (edited) You can use some Zenner diodes converting from 5 to 3v3. Not so efficient but it works just fine. Edited December 22, 2017 by daniel English can be hard Quote Link to comment Share on other sites More sharing options...

Michael McBride Posted December 25, 2017 Report Share Posted December 25, 2017 Could a pico PSU be used with this mod? https://www.amazon.com/Mini-Box-picoPSU-160-XT-Power-Mini-ITX-Supply/dp/B005TWE6B8/ref=sr_1_1?ie=UTF8&qid=1514165343&sr=8-1&keywords=pico+psu 1 Quote Link to comment Share on other sites More sharing options...
daniel Posted December 25, 2017 Report Share Posted December 25, 2017 This is the alternative version i was talking about. It gets the job done. 1 Quote Link to comment Share on other sites More sharing options...
N64 freak Posted December 25, 2017 Author Report Share Posted December 25, 2017 @daniel Yes it gets the job done. BUT have you ever heard of something called bad engineering? Diodes aren't the way to reduce the voltage. Yes the do drop the voltage about the same amount you would need but they don't allways have a guaranteed voltage drop and can differ form one to another diode. If you already build this up why not do it the correct way? @All if you build up such an adapter please don't go the cheapo route and use diodes. This simply is not a good way to do it even if it works. @Michael McBride Yes this adapter can be used in combination with a PicoPSU or any other ATX PSU. But one thing about the Pico PSUs. and other psus. Check how many amps the PSU can supply. The PicoPsus are a bit weak on the 5v rail for the xbox! Other than that plug in the adpter and an ATX psu and it works just like the retail psu. 1 Quote Link to comment Share on other sites More sharing options...
daniel Posted December 25, 2017 Report Share Posted December 25, 2017 As i said sir., not very efficient. I assume one does test the voltage before using this.. I put this here as an option. Sometimes we dont find/have the components we need. Quote Link to comment Share on other sites More sharing options...

BAM... N64 Freak Got your adapters yesterday. I'm putting them together today. They're gonna go in my two xbox PCs. HINT: Anyone wanting to put a xbox motherboard in a PC Case to: make the job easy you need to: 1. Make a MicroATX size (244mm x 244mm) adapter Plate that has both the PC motherboard standoff holes and the xbox motherboard standoff holes. 2. Position the Ethernet port directly behind the 2nd PCI slot down. I'm currently doing up a build log over on imgur you can find it here..

Они подключаются и воспроизводятся, чтобы легко переключаться между оригинальным psu и atx-psu. Могут использоваться для сборки casemods или ноутбуков. Адаптер построен вокруг следующей базовой схемы. Он правильно преобразует напряжение в режиме ожидания от 5 В до 3,3 В, а также переключает сигналы power_ok и power_good на правильные уровни. Также построена небольшая версия, которая может быть использована для создания адаптера стиля удлинителя, чтобы сэкономить больше места.

This is something we should all shoot for. A super small build. that would go well next to an XBOX ONE S. Now that would be a killer setup. Is there a Forum topic related to redoing a super small slim build? If not let's start one. Quote Link to comment Share on other sites More sharing options...
fox Posted February 27, 2018 Report Share Posted February 27, 2018 In all the threads I've seen, the people behind those super small builds would remove filter capacitors to reduce the draw on the 5v rail for the small PSUs to work. But they never gave an account of how the xbox behaves with those capacitors gone. That lack of info has kept me doubting the feasibility of a super small build.

Paul Tankard Posted April 28, 2018 Report Share Posted April 28, 2018 You still have these for sale? I was just about to get some pcbs created, butif it's most cost effective buying from someone who has already gone that path, hw much if so?
