As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example: ABS plastic contains styrene PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP) electrolytic capacitors can contain Ethylene glycol Brass can contain Lead flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA) Aluminum alloys can contain Chromium To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching! |

Blue Wire | |
| It appears the blue wire (molex pin 9 and FCI pin 5) is connected to a self-driven open collector "power good" output. If you connect 5V to it, it sinks 5mA (1k load) until the power supply is powered and then when it wakes up, the current drops to 0.5mA (10k load). The pair of BC548 transistors near the edge perform this function. | ||

Works great for me | |
| Both of the units I bought provide power with no additional strapping when connected to AC. The math says the outputs are 3.3 VDC ± 4%, 5.0 VDC +5%/-1% and 12.0 VDC ± 10%. The D-sub connector is an FCi D13W3S17B5GX3C and the pinout (determined by reverse engineering) is Pin A1: Ground (BLACK Wire), Pin A2: +5.0 VDC (ORANGE Wire), Pin A3: +3.3 VDC (RED Wire), Pin 1: 100Ω series resistor to +3.3 VDC, Pin 2: 100Ω series resistor to +5.0 VDC, Pin 3: Ground (BLACK Wire), Pin 4: Frame Ground, Pin 5: Some form of open collector status output (BLUE Wire), Pin 6: no connection other than to the WHITE Wire, Pin 7, 8 and 10: no connection, Pin 9: +12.0 VDC. The main output power connector appears to be an AMP Universal Mate-N-Lok II (plug housing 770023-1 with socket contacts). There are three 0.1" pitch headers with retention latches on a vertical board next to the larger heat sink. Each one has Ground and +12.0 VDC. My guess is they were for powering fans. | ||

Good price for these units | |
| First, be aware of 110 watt rating. That is total that can be drawn, even though listing for voltages and currents show a total wattage of over 150 w. These units were manufactured over 20 years ago, so it took a bit for the capacitors to re-form, but now work fine. DB connector pins 7,8 and 10 are not connected. Pin 3 is ground. Pin 5 is blue wire on 15 pin connector. Pin 6 is white wire on 15 pin connector. This fact will allow you to route the 12 volt output to white or blue or both by jumpering on the DB connector. I worked on these in a 40 degree shop, so they took some time to start. I assume might do better in warmer location. This is good price for units putting out high current on the 3.3 and 5 volt outputs. | ||

Still working on it | |
| Blue wire connects to pin 5 of DB, white wire connects to 6 of DB. They appear to go nowhere else. Pins 7, 8 and 10 appear not connected. Still won't start with or without a load. Only other connector is PL2 which makes only two connections despite having 6 pins. Jumpering any of them to the other makes no difference. 3Com was absorbed by HP in 2009 and this board appears to be manuactured in 2000. | ||

No output when ac connected | |
| There must be some connection that needs to be made on the DB connector. Tried jumpering the other and it did nothing. Will try jumpering pins on DB and see what happens. | ||
