AI Server PSU
AI and GPU workloads create rapid, high-amplitude load transients — NVLink bursts, NVMe array spikes, accelerator duty cycles — that standard server PSUs are not rated for. The AI Server PSU series addresses this directly: higher transient response, thermal management for sealed high-ambient enclosures, and output ratings matched to GPU accelerator tray power budgets.
Handles rapid, high-amplitude load transients from NVLink bursts, NVMe array spikes, and accelerator duty cycles. Output ratings matched to GPU accelerator tray power budgets. Thermal management for sealed, high-ambient enclosures. Available in CRPS-compatible and custom form factors.
Available power ratings and form factors on request — specifications vary by chassis architecture and GPU platform.
System Integration & Support
Selecting and integrating server power components requires more than a datasheet match. Sudtech provides chassis compatibility evaluation, load-profile analysis, thermal derating review for high-ambient installations, and certification support for your target markets.
