What does CRPS form factor mean?

CRPS (Common Redundant Power Supply) is a standardized PSU footprint of 1U height, 73.5mm width and 185mm or 265mm length, allowing swapped vendors and N+N redundancy in compliant server chassis.

Why is 54V output preferred for AI racks?

54V direct-to-rail architectures reduce double conversion losses versus 12V distribution and carry more power per conductor, which suits GPU-dense racks.

What efficiency does 80 PLUS Titanium require?

For 230V internal redundant supplies: 90% at 10% load, 94% at 50% load and 96% at 100% load.

What is the MOQ and lead time for OEM CRPS orders?

Standard MOQ starts at 100 pcs with 30–45 day lead times; pilot builds are available for type testing before mass production.

WHY 54V

One less conversion on the way to the GPU.

Legacy 12V architectures step down twice between the PSU and a modern accelerator. A 54V direct-to-rail feed skips a stage, carries roughly four times the power per conductor, and frees floor space for compute instead of copper. That is why the GB300 generation of AI racks standardized on high-current 54V shelves — and why our roadmap follows the mCRPS footprint TI and shelf vendors are converging on.

SMT & DIP

Power stages placed on dedicated high-current lines with SPI paste checks and AOI after reflow.

Auto test

Hi-pot, ground bond, in-circuit and functional stations log every serial to the unit record.

100% burn-in

Full-load aging room cycles at elevated temperature; zero-defect exit criteria per lot.

Compliance pack

UL 62368-1 evidence, 80 PLUS style reports and export docs assembled per destination market.

OEM / ODM OPTIONS

Configured to your chassis, not ours.

Connector families, faceplate silk, fan curves, PMBus maps and packing are all program parameters. Typical OEM engagements start from a chassis drawing and end with a shelf-ready kit — including matching power shelves and BBU bays from our integration line.

FAQ

CRPS questions we hear most.

What does the CRPS form factor actually standardize?

The PSU footprint: 1U height, 73.5mm width and 185mm (short) or 265mm (long) depth, plus connector and handle positions. It lets one chassis accept qualified supplies from multiple vendors in N+N configurations.

Why is 54V output becoming the AI standard?

At the same power, 54V carries about a quarter of the current of 12V, cutting conduction losses and cable mass. Direct-to-rail 54V architectures also remove one DC-DC conversion stage between PSU and accelerator.

What does 80 PLUS Titanium guarantee?

For 230V internal redundant supplies: 90% efficiency at 10% load, 94% at 50% and 96% at 100% — the highest 80 PLUS tier and the de-facto requirement for high-density AI procurement.

Can you match our existing shelf firmware polling?

Yes. PMBus command maps, telemetry fields and LED behavior are configured during the pilot build so the shelf manager sees a familiar device.
