Corsair HX1000i SHIFT Power Supply, 1000W, 80 Plus Platinum - (CP-9020265-EU)

This Corsair HX1000i SHIFT is a high-end ATX power supply with 1000W power and 80+ Platinum certification – aimed at serious gaming and workstation configurations with a powerful GPU and lots of peripherals. You get a modular unit with high 92% efficiency, which means less loss, lower temperature, and quieter operation under load. Thanks to support for ATX 3.0 / PCIe Gen 5.0/5.1 and the included 12VHPWR (12+4) Pin connector, you are ready for modern and future video cards. All this comes in a black case with a large 140mm fan and weight around 3.55 kg, which suggests a massive internal construction.

What you get is a power supply that comfortably handles high-end CPU + powerful GPU, along with a few SSD/HDD and additional devices, without overheating. 1000W gives you a comfortable reserve for upgrades – for example, switching to a more demanding GPU or adding more drives and fans. 80+ Platinum and active PFC help provide more stable power and lower consumption from the outlet during long gaming or render sessions. The modular design reduces cable chaos – you only plug in what you actually use, which improves airflow in the case. Support for the 12VHPWR connector is key if you plan to or already have a new generation GPU that requires this standard.

• 1000W Power – sufficient for a high-end gaming or creative configuration with one powerful GPU and lots of storage, without being on the edge of the power supply's capabilities.
• 80+ Platinum certification – high efficiency (up to around 92%) reduces heat and losses, which in real conditions means quieter operation and lower power consumption.
• ATX 3.0 / PCIe Gen 5.0/5.1 support – guarantees compatibility with the latest standards and better behavior during sudden peak loads from modern GPUs.
• 1 x 12VHPWR (12+4) Pin – readiness for video cards from the latest generations, without relying on adapters.
• 4 x PCI-Express 6+2-pin – flexibility for cards from previous generations or additional expansion cards that require extra power.
• 9 x SATA and Molex x 6 – enough connectors for multiple SSDs, HDDs, fan hubs, and other peripherals in larger cases and NAS/server builds.
• Modular power supply unit – all cables are separate, which facilitates cable management and improves airflow in the system.
• 140mm fan – a large fan allows for lower RPMs for the same airflow, which usually results in lower noise under load.
• Active PFC – better voltage stability and cleaner power to components, especially important with an unstable network.

Who it is suitable for: if you are building a powerful gaming PC, streaming/render machine, or workstation with a high-end GPU and lots of storage, this power supply gives you the necessary headroom for growth. It is especially sensible if you plan a GPU from a new generation with a 12VHPWR connector and want a current ATX 3.0 standard. It is not a particularly logical choice for very budget systems, where 1000W and Platinum class simply won't be felt.

The combination of 1000W, 80+ Platinum efficiency, and ATX 3.0 with 12VHPWR makes this Corsair HX1000i SHIFT a very stable base for a serious build with upgrade potential. If you are looking for a power supply that you won't replace with the next video card – this is exactly in that direction.
