I rewired my ATX power supply breakout board so that I would have ready access to the fuses. Probably gonna blow a few of those! The fuses are 5A 250V fast blow (F5A250V) so I can’t draw more than 60 Watts (at 12V). You can see in the previous post and the picture at the bottom of this post that the terminals used to be connected above the fuses, impeding access.
The ATX power supply breakout board is a Geekcreit® XH-M229 Desktop Computer Chassis Power Supply Module ATX Transfer Board Power Output Terminal Module.
This is the new setup:
This is the old setup:
On my bench I have a test mains power input for testing Xboxes along with a test AV cable connected to a TV.
Today I wired an Xbox power safety device into the mix. There’s a tear down of this highly over-engineered device on the EEVBlog video: EEVblog #1164 – Xbox Engineering Baptism Of Fire.
Microsoft made this to cover for defective mains power connector in their earliest hardware versions. The problem was that the socket was only soldered into the board and didn’t have sufficient mechanical support. The solder joints could wiggle around, become loose, get hot, and then let go the magic smoke.
Anyway this device is both a fuse and an earth leakage detector, so very happy to have it as part of my setup.
Got myself an XH-M229 board so I could repurpose an old ATX power supply. Apparently it’s suitable to use 1 amp fuses. Gonna send the 12V rail into my RD6006W bench power supply.
