21P8243 IBM Power Supply 1475W

IBM Power Supply Unit — hot-plug redundant PSU for IBM System x (pre-2014) / Lenovo ThinkSystem servers.

Specifications

• Part Number: 21P8243
• Brand: IBM
• Wattage: 1475W output
• Efficiency: 80 PLUS Bronze / Silver / Gold / Platinum / Titanium
• Input: 100-240V AC / 200-240V AC high-line / -48V DC (telecom variants)

Compatibility

IBM PSUs are chassis-keyed. Common-Redundant Power Supply (CRPS) modules are standardized across many System x models, but verify chassis form factor + redundancy mode before order.

• 550W / 675W: System x x3550 M2/M3/M4 — entry compute
• 750W Bronze/Silver/Gold: System x x3550 M4/M5, x3650 M2/M3/M4 — mainstream
• 900W / 1100W Platinum/Titanium: System x x3650 M5, x3850 X6, x3950 X6 — high-density / scale-up
• 1400W / 1600W / 2100W: Flex System Enterprise Chassis / GPU-rich nodes

Use Cases

Redundant (1+1) hot-plug power for production System x deployments. IMM2 / iLO-equivalent integration reports PSU health, voltage, draw, predictive failure. Titanium-grade reduces datacenter cooling load + OPEX.
