CRPS 1600W–2400W High-Density Titanium

The top of our in-production ladder. At 1600W, 2000W and 2400W, these CRPS-185 modules pack 75 W/in³-class density into the same 1U envelope as an 800W unit a generation ago — fed by a C19 inlet at 200Vac and hardened for the front-end role in GPU nodes and high-availability storage. Everything here ships today: no asterisks, no roadmap language.

1600W

1600W — GPU-Option 2U

For 2U nodes with two or three accelerators, or dense NVMe storage shelves. At 96% efficiency a 1600W unit at half load converts 800W with barely 33W of loss — heat that would otherwise be your rear-exhaust problem.

2000W — Front-End Standard

The workhorse rating for GPU front-end arrays: three 2000W units in N+1 feed a node drawing up to 4kW with a full spare. Active current sharing holds all units balanced so no single module carries the ripple peaks alone.

2400W — Envelope Max

The practical ceiling of the classic CRPS-185 12V architecture before the industry moves to modular 54V designs. Pairs with our M-CRPS roadmap: when your node outgrows 12V distribution, the transition path is already defined.

Why Density Matters

75 Watts Per Cubic Inch, and What It Buys You

Rack units are the scarcest currency in the data center. Pushing density from 40–50 W/in³ to 75 W/in³ class means a 2U GPU server fits its full 4+1 front-end inside the chassis with no add-on shelf — or a storage array dedicates the saved space to another dozen drives. Density is also a cooling statement: higher conversion efficiency plus compact magnetics keep hotspot temperatures inside the −5°C to +55°C continuous-output window, even in rear positions where intake air has already picked up heat from the GPUs ahead of it.

Feeding GPU nodes at 12V

Below roughly 3kW per node, 12V distribution stays economical: a 2000W front-end array feeds VRMs directly, no intermediate bus conversion stage, fewer points of failure. Density and efficiency — not voltage — are the winning levers in this band.

The 2400W boundary

Above 2400W, physics favors higher bus voltage. That is exactly where our development-sample M-CRPS 3000W–5500W program picks up, targeting 54V ORv3 slots — the same golden-finger chassis culture, one voltage class up.

Redundancy

N+1, N+N, and the Modes In Between

Active current sharing

Parallel units load-share within a few percent, so N+1 arrays run all modules at low stress instead of one primary aging at full tilt. Share-bus design tolerates hot insertion and pull of any unit.

Cold redundancy

A standby module stays unpowered until PMBus health telemetry flags degradation in an active unit, then swaps in. This preserves wear-level balance across the fleet and extends effective service intervals.

Power throttling

When a module drops out, the PSU asserts the throttle signal so host firmware can shed non-critical load gracefully — the difference between a routine logged event and an unplanned service window.

Applications

GPU node front-end power

2U–4U accelerator servers in the 3–8kW system class use 1600W–2400W arrays at 12V. PMBus telemetry rolls per-module health into your BMC so a degrading fan or drifting output is a ticket, not a 3 a.m. page.

High-availability storage

Dual-path storage controllers pair these units with N+N cabling across two power domains. Full output to +55°C suits sealed disk-dense drawers where exhaust re-ingestion is unavoidable.

FAQ

At 2400W, a 120Vac/15A C13 feed simply cannot carry the input current. Full rated output is specified from 200Vac on a C19/C20 path; below that the unit derates per the input-voltage curve in the datasheet. Budget your PDU and branch circuits accordingly — most GPU rack PDUs are C19-native already.
Typical deployments run three to six units on a shared current-share bus. The practical limit is your backplane and breaker design rather than the supplies themselves; we validate the sharing accuracy across your actual unit count during first-article testing.
One module sits unpowered as a spare. When PMBus telemetry from the active units shows accumulating stress — fan bearing wear, capacitor aging trends — the controller brings the cold spare online and retires the veteran. Fleet wear stays balanced and the spare is proven under load before it is ever needed.
Yes for classic CRPS. Above this band we offer the 3000W–5500W M-CRPS series as development samples for joint evaluation, and we label it as such — ask us for the current development status and sample availability.
