- For more information, see this article's corresponding Wikipedia page: IBM Personal Computer XT.
Released as the IBM Personal Computer XT, or PC/XT, the 5160 is based around Intel's 8088 processor featuring 8-bit ISA slots for expansion cards. It came with one 5.25" floppy drive, and one 5.25" full height HDD most commonly 10MB. The PC/XT used a 130W power supply.
| Preliminary Information | |
|---|---|
| Release Year | 1983 |
| Leak Risk | Low |
| Batteries | None |
| Capacitor Types | Aluminium Electrolytic, Tantalum, Ceramic |
| Destructive Entry | No |
Known Issues
No Power
Causes
- Power supply will not turn on
Solutions
- Power supply must have a load on it to activate
- Recap
Disassembly Notes
The external casing must be tilted up when pulled all the way forward to release.
Watch out for the speaker on the left side when sliding the casing.
The centre screw tab may catch on the PSU and cable (lift rear of case when sliding avoid).
PSU is held by four 1/4" hex screws to rear of PC case and two slides on bottom of PC case and needs to be slid toward front of PC to release.
When connecting the PSU back to the system the mother board power connectors P8 and P9 should have the black wires next to each other.
The PSU case has two Torx T15H security screws in addition to the standard 1/4" hex screws.
Once the PSU is opened, there are four 1/4" hex screws that need to be undone to fully remove the main board, in addition to an earth wire and connector from the AC input board.
There are three sub-boards attached to the main PSU board that generally do not need to be removed to access all the electrolytic caps.

PSU example 1
-
PSU example 1 board identifiers
-
Decapped PSU example 1
-
C3 on overcurrent sub-board (reversed polarity?). See note 2.
-
PSU example 2
Notes:
- In the two PSU examples shown here, the three sub-boards extending towards the camera are left Voltage Windows, centre Overcurrent Monitor, right Inrush Limiter
- The polarity of the C3 cap on the Overcurrent sub-board appears to be marked incorrectly on the board. See picture above. Check and confirm before removing/replacing. Presumably the PSU functioned correctly for most of its life and the manufacturer knew to ignore the polarity marking for this cap.
