CRPS Titanium PSU
The 3200W class that made 120 kW racks electrically practical.
CRPS standard and titanium tier
CRPS modules are the rack-level building block for high-density AI servers because they package redundant power in a shared, hot-plug form factor. The benchmark part in this class is the HPE 3200W M-CRPS Titanium power supply, which carries an 80 PLUS Titanium rating and supports hot-plug replacement without dropping the bus. In 48V ORv3 deployments, CRPS modules feed GPU trays directly and avoid the losses of legacy 12V conversion.
That rating is not marketing: 80 PLUS Titanium requires 96% efficiency at 50% load. For procurement, titanium means fewer watts lost per module and tighter thermal control in dense enclosures. Specify CRPS only after confirming the 3200 W rating, 80 PLUS Titanium test reports, and UL 62368-1 safety documentation before sample approval.

What to specify in the RFQ
- Set 3200 W minimum per module and budget 120 kW per AI rack.
- Require 80 PLUS Titanium test data showing 96% efficiency at 50% load.
- Spec UL 62368-1 safety compliance with factory test reports before shipment.
- Define hot-plug N+1 redundancy; no single module should derate below rack demand.
- Confirm 48V ORv3 architecture compatibility for GPU trays, not legacy 12V.
Efficiency economics at 120 kW racks
AI racks now cross 120 kW per cabinet, and Wedbush 2026 sees liquid cooling as mandatory. At 120 kW of load, a 96% efficient titanium module turns roughly 5 kW into heat before the server board ever sees a watt. A lower-tier 94% supply would push about 7.7 kW of loss into the same envelope, adding liquid-cooling burden.
That 2.7 kW per-rack delta is why titanium is treated as a thermal spec, not just an energy cost line. Procurement teams should compare efficiency at half load, not peak, and require 80 PLUS Titanium test reports for every lot. The 3200W class keeps N+1 redundancy practical at 120 kW while avoiding derating or bus instability.

What titanium efficiency actually saves
The gap between 94 percent platinum and 96 percent titanium looks small until you multiply it by a rack: a 120 kW cabinet wastes roughly 2.4 kW less at titanium level, which is 21 MWh per rack per year. At 0.1 dollars per kWh that is 2,100 dollars annually per rack — before counting the cooling saved on that waste heat.
