Corsair RM1000x — 1000W Fully Modular ATX 3.1 Power Supply
1000W ContinuousCybenetics GoldATX 3.1 / PCIe 5.1Fully Modular
The Corsair RM1000x (part number CP-9020271-EU) is a 1000-watt fully modular ATX power supply built for high-performance gaming PCs and workstations that pair a power-hungry graphics card with a modern CPU. It is ATX 3.1 compliant with PCIe 5.1 support and ships with a native 12V-2x6 GPU cable, delivering Cybenetics Gold and 80 PLUS Gold efficiency from 100% Japanese 105°C-rated capacitors. Typically in stock with fast delivery across Cyprus.
Compatibility & fit
This is a standard ATX form-factor PSU measuring 160×150×86 mm — confirm your case supports a 160 mm-deep ATX unit. The included native 12V-2x6 cable powers modern GPUs (e.g. NVIDIA RTX 40/50 Series) directly; older cards use the four supplied PCIe 8-pin (6+2) cables. Being fully modular, you only connect the cables your build needs.

Key Features
ATX 3.1 & PCIe 5.1 ready
Compliant with Intel’s ATX 3.1 standard and PCIe 5.1, with a native 12V-2x6 connector that delivers up to 600W to a single modern graphics card and tolerates demanding transient power spikes.
Cybenetics & 80 PLUS Gold efficiency
Dual Gold-tier certification means high energy efficiency and low heat, while a Cybenetics Noise rating of A confirms exceptionally quiet operation.
140mm Zero RPM fan + override knob
A 140mm fluid dynamic bearing fan stays silent under low to medium loads thanks to Zero RPM mode, with a manual override knob to force extra airflow when you want it.
Fully modular, Japanese capacitors
Connect only the Type-4 cables your system needs for tidy builds, backed by 100% Japanese 105°C-rated electrolytic capacitors for years of stable power.

Frequently Asked Questions
Singular Expert Insight
The RM1000x sits at the top of Corsair’s mainstream RMx line. If your build draws less, the RM850x or RM750x offer the same platform and efficiency for less money, while the RMx Shift is worth considering if you want its side-mounted connectors for a cleaner power supply install. Choose the 1000W RM1000x when you are running — or planning to run — a high-wattage graphics card and want comfortable headroom plus genuine ATX 3.1 transient handling.
Buyer’s Guide
Buy it if
You are building or upgrading a high-end gaming PC or workstation with a 250W+ GPU and want ATX 3.1 future-proofing plus silent Zero RPM operation.
Skip it if
Your system draws under ~500W (the RM750x is cheaper) or you need a compact SFX unit for a Mini-ITX case — the RM1000x is full-size ATX.
Also consider
The RM850x for mid-high builds, the RMx Shift for side-mounted cabling, or the HXi series if you want digital power monitoring through Corsair iCUE.
