1000W+ Power Supplies
When you're running a high-end gaming rig, a demanding workstation, or a system packed with multiple GPUs and storage drives, a 1000W power supply gives you the headroom to perform without compromise. CORSAIR's range of 1000W+ PSUs is built for PC builders who want reliable, efficient power delivery across every load condition. Browse our full range to find the right unit for your build.
Why Choose a 1000W Power Supply?
A 1000W power supply suits builds that draw significant power under sustained load. Modern high-performance GPUs and CPUs can consume hundreds of watts each, and when you factor in storage, cooling, and other components, headroom matters. A 1000W PSU lets your system run comfortably within its power envelope rather than pushing against its ceiling. This translates to more stable voltage delivery, quieter fan behaviour under typical loads, and room to upgrade components down the line without replacing your PSU.
All CORSAIR 1000W+ power supplies carry 80 PLUS or Cybenetics certification, with options spanning Bronze and Platinum efficiency ratings. Higher efficiency means less wasted energy converted to heat, which keeps your system cooler and your electricity costs lower over time. If you're running your PC for long gaming or rendering sessions, efficiency adds up.
If you're building with a current-generation GPU, look for a 1000W power supply that supports ATX 3.0 and PCIe 5.0. These standards handle the transient power spikes that modern graphics cards can produce, ensuring stable performance during intense gaming or compute workloads.

Modular, Semi-Modular, and Form Factor Options
Choosing the right 1000W PSU also means thinking about cable management and case compatibility:
- Fully modular: Attach only the cables you need, keeping airflow clean and builds looking sharp.
- Semi-modular: Essential cables are fixed, with optional extras you connect as required.
- ATX: The standard form factor for full-size and mid-tower cases.
- SFX: A compact form factor for small form factor builds that still need serious power.
Selecting the Right 1000W PSU for Your Build
When you're running a high-end gaming rig, a demanding workstation, or a system packed with multiple GPUs and storage drives, a 1000W power supply gives you the headroom to perform without compromise. CORSAIR's range of 1000W+ PSUs is built for PC builders who want reliable, efficient power delivery across every load condition.
Consider your GPU and CPU's combined TDP, add overhead for peripherals and storage drives, and choose a unit rated comfortably above your estimated peak draw. Pair that with the efficiency rating and form factor that fits your case, and you have a solid foundation for any high-performance build.
For compact systems that still demand serious power, explore our range of SFX Power Supplies. Or browse the full CORSAIR range of modular power supplies to find the unit that fits your setup.
Whether you're pushing the limits with a multi-GPU workstation or future-proofing a high-end gaming build, CORSAIR's 1000W+ PSUs deliver the stable, efficient power your system deserves.
