Power supply Corsair RM1000x 1000W 80 Plus Gold ATX 3.1 PCIe 5.1 Fully Modular PSU - CP-9020271-EU

This Corsair RM1000x is a 1000W ATX power supply with 80+ Gold certification and modern standards ATX 3.1 / PCIe Gen 5.1, aimed at mid- to high-end gaming and work configurations. The combination of high power and 90% efficiency gives you a serious reserve for powerful GPUs and many peripherals, without unnecessarily raising the electricity bill. The fully modular design helps you organize the cables neatly, and the 140mm fan handles cooling quietly. No RGB, in a clean black color – the focus is on stability and functionality, not on lights.

What you get is a power supply ready for modern and future graphics cards thanks to the PCIe 12V-2x6 (12+4-pin) connector and ATX 3.1 / PCIe Gen 5.1 support. 1000W power means you can safely combine a powerful CPU, serious GPU, many SSDs/HDDs, and additional fans without worrying about power shortages. With 90% efficiency, less energy is lost as heat, which also helps with the overall temperature in the case. Active PFC ensures that the power supply operates stably over a wide input range of 100 – 240 VAC, which is important if the mains voltage is not perfect. The 140mm fan provides greater airflow at lower speeds compared to smaller fans, which usually means lower noise under normal load.

• Power 1000W – sufficient for high-end gaming or productive configurations with a powerful GPU and many devices, without reaching a bottleneck from the power supply.
• 80+ Gold certification and 90% efficiency – less energy loss as heat and more stable operation under high loads.
• ATX 3.1 / PCIe Gen 5.1 support and PCIe 12V-2x6 (12+4-pin) connector – ready for modern and future graphics cards without the need for adapters.
• Fully modular design – connect only the necessary cables, improving airflow in the case and making assembly and future upgrades easier.
• Rich set of connectors: 4x PCIe 8-pin (6+2), 2x EPS 8-pin (4+4), 12x SATA and 6x PATA – allows you to connect many drives, fans, and other devices without additional splitters.
• 140mm fan – larger blade for better cooling at lower speeds, which helps for quieter operation under typical gaming load.
• Compact dimensions 150 x 86 x 160 mm for ATX format – fits seamlessly in most mid and full tower cases.
• 120-month warranty – long-term security for a component that is key to the entire system.

Who it is suitable for: if you are building a serious gaming or workstation build with a powerful GPU and plan upgrades in the coming years, this power supply gives you the necessary reserve and modern connectors. It is also suitable for configurations with many storage devices or peripherals. If you are making a very budget build with low consumption, 1000W is probably excessive, but for mid- and high-end systems, it is a very good centerpiece of the platform.

The combination of 1000W, 80+ Gold efficiency, ATX 3.1 / PCIe Gen 5.1, and fully modular design makes this Corsair RM1000x a solid foundation for a long-term build. The fact that it comes with a long warranty and readiness for new GPU standards is its strongest argument.
