Power Supply | DC Power Distribution
The 200-W power supply can operate from an AC power source of
115 VAC at 60 Hz or 230 VAC at 50 Hz. The power supply provides
the DC operating voltages and currents listed below.
 |
NOTE: The power supply produces DC voltages only
under its loaded condition. The DC power cable connectors
must be connected to their corresponding power input
connectors on the system board or drives in order to
measure these voltages. |

| +3.3 VDC |
+3.14 to +3.47 VDC |
14.00 A |
The combined load on the +3.3-VDC and +5-VDC outputs
cannot exceed 140 W. |
| +5 VDC |
+4.90 to +5.25 VDC |
22.00 A |
The combined load on the +3.3-VDC and +5-VDC outputs
cannot exceed 140 W. |
| -5 VDC |
-4.50 to -5.50 VCD |
0.300 A |
|
| +12 VDC |
+11.40 to +12.60 VDC |
6.00 A |
The +12-VDC output can withstand surges of up to 11.0
A to support disk start-up operations. |
| -12 VDC |
-10.80 to -13.20 VDC |
0.300 A |
|
| +5 VSB |
+4.75 to +5.25 VDC |
0.010 A |
The +5 VSB (volts standby) is sometimes called
"flea power." |
See "DC Power Distribution" in Chapter 1 of the Service Manual for information about
the DC power distribution.
