Corsair RM1000x 1000W 80+ Gold PSU

The Corsair RM1000x 1000W 80+ Gold is a premium fully modular power supply designed to power the most demanding gaming and workstation PC configurations with Japanese primary capacitors for long-term reliability and low-noise operation under all load conditions. The 1000W continuous output capacity accommodates system configurations including NVIDIA RTX 4090 GPUs, Intel Core i9 or AMD Ryzen 9 processors, and multiple high-capacity NVMe SSDs without approaching the PSU’s output ceiling. The 80+ Gold certification confirms greater than 90% efficiency at 50% load, minimizing heat generation and electricity waste during typical gaming and productivity workloads. The fully modular cable design allows unused cables to be omitted from the build entirely, dramatically improving cable management and case airflow compared to semi-modular or non-modular alternatives. The Zero RPM fan mode operates silently below 40% load, activating the 135mm fan only when thermal conditions require active cooling. Corsair’s Type 4 generation cables include a native 12VHPWR connector for direct NVIDIA Ada Lovelace GPU connection without adapters. The 10-year warranty — the longest offered by any major PSU manufacturer — reflects Corsair’s confidence in the RM1000x’s long-term reliability. ATX 3.0 compliance ensures compatibility with current and next-generation platforms.
