The PSU pinout of the Model 150 is nowhere to be found on the net. This article should change that.[1]
Connector to Colors
The board has connectors for five cables coming from the PSU. The connectors on the board are labelled 1, 2, 9 (first row), and 10, 11 (second row). All but 9 are mechanically standard 6-pin PC/AT PSU connectors.
All descriptions are taken from an original 150 PSU.
Connectors 1 and 2 are also mostly standard AT pinout.[2]

Footnotes
- ↑ This is a preparing work for another article describing how to replace an original 150's PSU with a stock PC one.
- ↑ The only difference being the white wire, supplying -5 V on the PC/AT; designated VFAN for the AS/400 PSU, also delivering -5 V.
- ↑ 5 V Standby Power
- ↑ Signal designation as regex: [EF][PB]O[UW]. The circuit board label is partly covered by a very sticky white substance; no silicone rubber. Scratching it away also removes the print.
- ↑ has 7.8 V after power on.
