Notes:
1. The 300 W power supply meets or exceeds the specifications in the above table. For the
noted specifications, the Maximum values describe the smallest acceptable maximum
load, and the Minimum values describe the largest acceptable minimum load.
2. These outputs are measured at the connector of a loaded cable.
3. The +3.3 V and +5.0 V outputs do not draw more than 240 watts combined.
4. Any combination of +3.3 V, +5.0 V, and +12 V do not exceed their maximum or 300
watts of total power.
5. The +12 V output is able to supply a peak current of 7 amps for 30 seconds.
6. The sum of Initial Setting Tolerance and Line/Load Regulation does not exceed 3% for
+3.3 V output, 3% for +5.0 V output, 5% for +12.0 V output, and 10% for negative
output voltages.
7. Current always flows from the +12 V (or -12 V) output to the fans.
8. No output exceeds 240 VA under any condition.
