I replaced the rest of the caps and got the voltage for yellow to 12.3v and the red up to 5.3v. Its running great now. The guy might consider the HDMI mod but the parts are backorder..

I had some caps on hand and changed out the 47uf 25v and 1000uf 16v. I was able to tweak out to 10.92v on yellow and 4.85v on red. The hard drive is able to power up off the Xbox power supply. That is really on the edge of threshold there

With this mod, are you guys transferring the Xbox components out to a computer/custom casing? Otherwise how fit the atx power supply in xbox case. I probably have some atx power supply I can butcher.

I'll probably order the cap kit since it will still be cheaper than getting used supply. They are running around $30-40 shipped. If the voltage was 11.5v instead of 10.5v the hard drive would power up.

I looked at the board and it says ~120vac, so no its not a 220vac. It's kinda funny when I was trying to adjust the pot, is that the adjustment range is very small like less than 1/8 of turn. Anything more the xbox won't even turn on. It had the tamper factory seal on it and took off to adjust.

The molex connector has the same readings where the red is 4.48v and the yellow is 10.5V. When the HD is connected to the xbox power supply you hear a slight click, no hard drive spinup. I checked the voltage at the DVD connector and it is 10.5v and 4.48v as that is the same voltage coming off power supply. The Thompson DVD drive works fine as I was able to TSOP the board and update the dashboard. I flash with the OG XBOX DVD tool disc. The xbox was having this issue before I TSOP. I found a cap kit at console5 for my power supply that I might order. https://console5.com/store/checkout/cart/configure/id/293349/

I am repairing xbox 1.4 for a friend. His box is having power supply issue. There is not enough volt to run the hard drive. I used external 12v/ 5v source to power the hard drive and the system boots up fine. The dvd disk drive is also working fine as it is connected to the xbox power supply. I took the xbox power supply out and didn't notice any bad caps or bad solder joints. With everything connected and powered up ,except for the power to the hard drive I get the following voltage values. Orange = 3.3V, Blue = 3.3V, Brown =3.3V, Red = 4.48V, and Yellow = 10.5V. I tried adjust the pot and that is max i can get for red and yellow wires. Which caps do I need replace for these two voltages ? or is there something else i can check? Thanks.

Hi everyone, good to know that there are still people in the mod scene. The xbox was my first mod that got me started and modding stuff till these days sx chip on switch.
