Best PSU for AMD Ryzen Threadripper 9980X and 9970X

High-end workstation CPUs like AMD’s Threadripper 9980X and 9970X demand serious, stable power — not just at peak load, but across workloads with variable draw (rendering, simulation, compute, etc.). Choosing the right power supply unit (PSU) is critical to system stability, longevity, and headroom for future upgrades.

• 1200W-3000W power supply, especially depending on quantity of high-end GPUs
• sTR5 socket motherboard with DDR5 support (ex. TRX50 AERO D)
• Discrete graphics card, as Threadrippers do not have integrated graphics
• Capable CPU cooler

When choosing the right PSU for your Threadripper 9980X/9970X build, the most important considerations is how many GPUs you plan to install or would like to have future-proof capability for. You can also utilize our tools below to help you make the right decision.

• PC Builder - the full solution that walks you through recommendations of compatible cases, storage, memory kits, and coolers, and power supplies.
• Power Supply Calculator - choose your GPU and CPU, answer a few quick questions, and we'll suggest the best few PSU options for your setup.

Otherwise, we've pinpointed the best PSUs for your Threadripper 9980X/9970X build below.

If you're looking to have the max amount of GPUs in your Threadripper build, then our WS3000 will be the necessary choice as it provides sufficient wattage and connectors for your components. It is entirely designed around for multi-GPU workstations intended to complete enterprise-grade workloads. Certified with 80 PLUS® Platinum level efficiency, you'll also be outputting power at top-tier efficiency in terms of lower power consumption, noise, and temperatures.

If you're pondering an entry-level workstation but won't be able to expand it until later down the line, then the WS3000 may also be a worthy consideration for futureproofing. You can read our main page on the WS3000 to learn more It is also worth noting that the WS3000 requires a 200V+ AC main.

For those who are assembling an entry-level or advanced Threadripper/workstation build, then our HXi Series PSUs will be perfect. They range from 1000W to 1500W, tailoring to both entry-level & advanced Threadripper workstation builds.

• HX1200i - meets AMD's minimum wattage requirement for Threadripper paired with an entry-level GPU
• HX1500i - provides sufficient wattage for the Threadripper + one high-end GPU

Both the HX1200i and HX1500i possess 80 PLUS/Cybenetics Platinum certifications, providing top-tier efficiency, and lower power consumption and noise, and cooler temperatures.

Alternatively, if you're in a hurry for an AI workstaton and don't have the time to assemble one, then our AI Workstations would be a great solution especially for starters. Alternatively, our friends at ORIGIN PC have their Threadripper systems for those with higher demanding workloads.
