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.

Compatibility

• ✓ ATX12V form factor: fits standard full-size ATX and larger workstation cases.
• ✓ Motherboard connector: 24/20-pin main power plus dual 4+4-pin CPU connectors for high-core-count processors.
• ✓ Graphics cards: two PCIe 5.1 16-pin connectors (600W each) plus four PCIe 6+2-pin connectors for legacy or additional cards.
• ✓ Storage and peripherals: nine SATA connectors and three peripheral (Molex) connectors for drives and legacy devices.
• Note: AC input 200-240V only; requires appropriate regional power cord for your country.

Best For / Trade-offs

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.
