For HP Z8 G4 Workstation 1700W Power Supply DPS-1450AB A 1450W 1550W Universal
Brand: Unbranded Color: Silver Model: DPS-1450AB A Features: Dual Power Capacity 1450W at 110V input and 1700W at 220V input. Most consumer PSUs stay at one fixed wattage; this workstation PSU scales up when provided with higher voltage input (common in data centers/labs).
Multi-Rail Design (Server-Grade) Instead of one giant +12V rail, it provides separate, dedicated 12V rails for: CPU 0 (Xeon 1) CPU 1 (Xeon 2) GPUs (G1/G2/G3) Storage / M.2 This ensures power isolation so a sudden GPU spike won’t destabilize CPU or memory operations — critical for workstations running simulations, rendering, or AI tasks.
Hot-Pluggable / Tool-Less Replacement Unlike normal ATX PSUs, this unit is hot-swappable in the HP Z8 G4 chassis. IT admins can replace it without shutting down the workstation (if redundant PSU configuration is installed). Great for mission-critical environments where downtime is unacceptable.
Enterprise-Grade Efficiency Designed to meet or exceed 80 Plus Platinum efficiency (~94% at 50% load). Lower heat output, lower power waste, and more stability under constant 24/7 workloads compared to gaming PSUs.
Advanced Protection Systems Includes all high-level protections (OVP, OCP, OTP, SCP, OPP, UVP). But importantly, it uses per-rail current limiting — meaning if a GPU draws too much power, only that rail is affected, not the whole system.
Intelligent Cooling Large, variable-speed server-class fan with temperature-sensing control. Optimized for workstation airflow in the HP Z8 chassis (reduces acoustic noise while keeping critical components cool).
Built for Multi-CPU, Multi-GPU Workloads Supports: Dual Xeon Scalable CPUs with independent dedicated rails. Up to 3 professional GPUs (NVIDIA RTX A6000, Quadro, Tesla, etc.). Massive amounts of ECC memory + multiple SSD/HDD drives. Power delivery designed specifically for AI/ML training, 3D rendering, CAD, scientific computation.
