Server PSU & CRPS
Titanium-class power modules that feed GPU trays at 96% efficiency.
CRPS Form Factor Family for AI Racks
Common Redundant Power Supply (CRPS) modules are now the dominant form factor for high-density server and GPU racks. The 2026 class is defined by the HPE 3200W M-CRPS Titanium unit, which delivers 80 PLUS Titanium certification at 96% efficiency under half load. That efficiency directly cuts waste heat and lets procurement specify smaller cooling capacity per rack.
The same physical envelope now carries 48V ORv3 architecture, replacing the legacy 12V bus for GPU trays where current draw at 12V becomes unmanageable. Sourcing from Shenzhen manufacturers keeps lead times at 15–30 days for standard PSU batches, with Guangdong computing-hardware factories booked into next year for high-volume programs.

Efficiency Tiers: What Titanium Actually Buys You
Every point of efficiency matters when a single AI rack can cross 120 kW. A 96% Titanium module dissipates roughly 133W at 3200W output, while a 94% Platinum unit wastes 192W under identical load. Over a 7×24 fleet, that gap becomes hundreds of kilowatt-hours per rack per month.
The 48V ORv3 path also reduces copper losses in the tray bus by cutting current for the same power delivery. Procurement teams should compare total cost including cooling, UPS overhead, and busbar losses, not just catalog price per watt.
- Titanium 96% at half load — HPE 3200W M-CRPS reference
- 48V ORv3 replaces 12V for GPU trays above ~3kW per tray
- N+N redundant PSUs pair with ORv3 BBU shelves for ride-through
- UL 62368-1 compliance is mandatory for US data center deployments
