Quick update, I've been sick with some kind of respiratory illness, but I'm hoping to finish the mod completely today, and finish and upload the guide later tonight. Sneak peak:

Regarding the DVD drive, from my quick research after dinner I would need to hard mod and flash a bios to remove it completely. That said I am pretty confident I can disassemble the drive and remove all the plastic and metal and just leave the electronics in a small box, and the hard drive in front of that. Then dissect the PSU and hang it above the space for the old one. Cooling might be an issue, but I can definitely figure something out. Also thank you for your kind offer @MadMartigan, but I am on income support and live below the poverty line. My entertainment budget this month was about $7, and I spent it on 5 3300uf caps from a local place in the hopes of it fixing the no power issue. Everything I done since that replacement caps purchase has been with scavenged parts from electronics I've dissected going back 20+ years in some cases. I replaced the clock cap with a 220ohm resistor, and the Q7C2 transistor with a standard NPN transistor: Which still didn't fix the issue. I checked over the power supply board and there is nothing obviously wrong, which is why I started pulling caps to test. My prototype that I showed above has a couple of issues, otherwise I would post a picture of it here. On that note, should I make a new thread or just continue here for instructions/guide I am putting together?

I'm going to remove all the casing from the power supply and see if I can make it all fit, I have my doubts however. Good news is all my games just finished backing up now, including several rare-ish games that were stolen from me a few years ago. (Burnout Revenge and Baldur's Gate Dark Alliance II)

I can confirm that I have success with the modified ATX supply: Currently backing up everything via FTP as the hard drive has a lot of hours on it too. I will be putting together a guide as promised for the next guy, the power supply is from a mini-itx case that was going to the dump, I'm going to transfer the guts to that. Thank you for all your input, stay tuned for a guide.

Any other specific components that you know are prone to failure in these units? Or should I just desolder everything and check it all? Really wish I had a spare working one, but I cannot afford to buy a second one. I'm going to try to modify an ATX power supply today based on my limited knowledge, I'll post here if my house doesn't burn down.

Nothing on 5vsb. If the round brown component directly behind the plug is a fuse it is fine. I've tested most of what I could test in circuit, but didn't see anything obviously wrong, to my amateur eye. Couldn't find a troubleshooting guide, so I started desoldering caps to check them.

I am fiscally poor, I have half a dozen ATX supplies kicking around, a limited knowledge of lelectronics, and too much time on my hands. @KaosEngineer I had started pulling caps to test, of the 4 I pulled they are all within the standard 20%, only "oddity" is the 3300uf 10v cap, it's at 3843uf, but that's still ok, by "spec". I'll put it back together and let you know if I have standby voltage shortly. If you have a schematic or troubleshooting guide for the Tuscany power supply that would be greatly appreciated.

I agree with you 100%, but replacing a 18 year old power supply with another 18 year old supply is foolish, IMHO. An ATX Adapter is the best way to future proof my system, and considering the state of modern games, I would like it run, basically forever. In any case when I am done I will document how to replicate it, with pictures, for the whomever the next guy is. Thanks MadMartigan.

Can anyone confirm before I start building this that it will work? Please? I can't be the only person to have wanted this information the last few years, so I'm puzzled why I can't find any documentation.

Based on the ratings directly from the power supply board, the sickmods.net pinout has the 5v and 5vsb channels reversed There are 4 red wires and only 1 orange one, you can't put 13.6amps through one ATX pin:

Hello everyone. I have not done anything with my original Xbox 1.6b since I softmodded it over 15 years ago, and recently it stopped powering on. I've tried googling and researching, but the loss of Sickmods (and others that I probably don't know about) has made it difficult to find information. Attempts So far: Eject or power button does nothing. Replaced the 5 main caps that are known to leak (I'm pretty sure I did this 10 years ago as well, but had parts on hand so did it anyways) I have replaced the transistor near the clock cap (q7c2) I'm pretty sure its the power supply itself, (Its the Samsung Tuscany one) so I have been trying to modify an ATX supply to use to test. On the earlier versions of the XBox there are lots of information and adaptors, but not the 1.6b. The pinouts I have found for the 1.6 xbox (See below) show it needing 4 lines on 5Vsb, and only one standard 5V line: I'm pretty sure this is backwards, and it should be 1 standby line and 4 regular, can someone with more experience confirm? The other question is regarding the N64Freak adaptor board diagram: From what I have read the 1.6 uses 5Vsb instead of 3.3Vsb, can I omit the LM3490, the 33uf cap, and the link to the ground plane like so: Thank you in advance for any help you are able to provide, and if you have any good tips for a guy who is 15 years out of the scene, let me know.
