Power Supply Supported for Intel® Server M50FCP Family
Content Type: Product Information & Documentation | Article ID: 000094533 | Last Reviewed: 11/08/2024
Support Knowledge Base
The Intel® Server M50FCP supports the following power supply options:
- AC 1300 W (80 Plus Titanium)
- AC 1600 W (80 Plus Titanium)
- AC 2100 W (80 Plus Platinum, M50FCP2UR only)
Power supplies are modular and are installed from the back of the system where two power supply bays are located, one on each side of the chassis.
| Note | In dual power supply configurations, both power supplies must be identical. A system configured with two different power supply options is not supported. An unsupported power supply configuration will not provide power supply redundancy and results in the system generating multiple errors to the system event log. |
Power Supply Specification Overview
- AC 1300 W (80 Plus Titanium)
- AC 1600 W (80 Plus Titanium)
- AC 2100 W (80 Plus Platinum)
AC power supplies are auto-ranging and power factor corrected.

Power Supply Module Efficiency
Each power supply option is rated to meet specific power efficiency limits based on their 80 PLUS power efficiency rating. The following tables define the required minimum power efficiency levels based on their 80 PLUS efficiency
rating at specified power load conditions: 100%, 50%, 20%, and 10%.
The AC power supply efficiency is tested over an AC input voltage range of 115 VAC to 220 VAC.

Power Supply Configurations
Embedded platform management automatically determines and configures the power supply configuration based on the number of functional power supplies detected, and the total power draw of the system. The system supports the following power configurations:
- 1+0 – One functional power supply detected – no power redundancy. Supported if the power requirement of the system stays below the maximum power limit of the one functional power supply.
- 1+1 – Two functional power supplies detected – redundant power with hot replacement supported. Configured if the power requirement of the system stays below the maximum power limit of one power supply.
- 2+0 – Two functional power supplies installed – combined power, no redundancy.. Configured if the power requirement of the system is greater than the maximum power limit of a single power supply.
Closed Loop System Throttling (CLST)
Closed-loop system throttling (CLST) prevents the system from crashing if a power supply module is overloaded or overheats. If the system power reaches a pre-programmed power limit, CLST throttles system memory and/or processors to reduce power consumption. System performance is degraded if throttling
Smart Ride Through (SmaRT) Throttling
Smart Ride Through (SmaRT) throttling increases the reliability of a system operating in a heavy power load condition and contributes to remain operational during an AC line dropout event. When AC voltage goes low, a fast AC loss detection circuit inside each installed power supply asserts an SMBALERT# signal to initiate a throttle condition in the system. System throttling reduces the bandwidth to both system memory and processors, which, in turn, reduces the power load during the AC line drop out event.
