ASUS Pro WS 1600P 1600W Platinum ATX 3.1 Modular PSU
The ASUS Pro WS 1600W Platinum ATX 3.1 Modular PSU is built for professionals running demanding AI workloads and dual high-end graphics cards. It delivers rock-solid voltage stability and advanced power delivery through 80 PLUS Platinum efficiency and full ATX 3.1 compliance, with the cable infrastructure to support two GeForce RTX 5090 cards simultaneously.
Why this product
Supports dual RTX 5090 graphics cards
Engineered with the power delivery and voltage stability required to run two of NVIDIA's flagship GPUs in parallel, unlocking dual-GPU AI and deep learning workflows.
ATX 3.1 compliant with 16-pin PCIe 5.1 cables
Includes two 16-pin cables delivering up to 600W each to next-generation graphics cards, meeting tighter voltage and current regulation standards.
80 PLUS Platinum efficiency
Certified for 90% efficiency at 50% load, reducing heat output and electricity costs in always-on workstation environments.
Dual-ball fan bearings rated to last twice as long
Precision bearings extend fan lifespan versus sleeve designs, critical for 24/7 operation in professional settings.
Fully modular cables with gold-plated connectors
All cables detach for cleaner builds and easier replacement. High-performance copper pins resist oxidation and maintain stable connections under load.
Comprehensive protection and thermal management
Extruded aluminum heatsinks cool critical components. Six layers of protection (OPP/OVP/UVP/SCP/OCP/OTP) guard against voltage spikes, current surges and thermal faults.

Best for
- AI workstations and deep learning labs
- Dual-GPU rendering and compute workflows
- Professional 24/7 deployments requiring high reliability
- Data centers and managed hosting where efficiency reduces operating costs
- Builds requiring headroom for future GPU upgrades
Trade-offs
- Single-GPU builds: 1600W is overkill for systems with one graphics card; smaller capacity units deliver better cost efficiency.
- Budget-constrained projects: Platinum efficiency and workstation-grade components command a premium over Bronze or Gold units.
- Compact or small-form-factor cases: At 175 × 150 × 86 mm, it requires a full-size ATX chassis.
- Consumer or gaming systems: Designed for professional and enterprise use; consumer platforms do not require this power delivery architecture.
