Corsair HX1500i (2025) 1500W 80 Plus Platinum ATX 3.1, PCIe 5.1 PSU - CP-9020309-EU

Corsair HX1500i (2025) is a high-end 1500W power supply aimed at serious gaming and workstation configurations with power-hungry GPUs and multi-core CPUs. With an 80+ Platinum certification and up to 92% efficiency, the power supply is designed for long-term stability and lower energy losses. The form factor is standard ATX, and the length of 200 mm means you should consider it in relation to the case. This model can comfortably handle top-tier components, including PCIe 5.1 GPUs with the new connector standard.

What you get

With real 1500W and output of DC 3.3/5/±12 V, you have a huge power reserve for multi-GPU, top-level CPUs, and plenty of peripherals without worrying about instability under load. The two PCI-E 5.1 600W 12V-2X6 connectors prepare you for the latest and most power-hungry graphics cards without the need for adapters. Nine PCI-E 6+2pin, along with 3 x EPS 8-pin(4+4), allow complex configurations with HEDT platforms and additional cards. Thanks to the modular design, you keep the cables under control – you only plug in what you need, which also helps with airflow. The large 140mm fan, combined with high efficiency, means lower temperatures and less noise during typical gaming or work.

• Power 1500W – gives you serious headroom for high-end GPUs, powerful CPUs, and plenty of storage/accessories without the risk of power shortage.
• 80+ Platinum certification and up to 92% efficiency – less loss as heat, lower power consumption, and more stable operation under high load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 compatibility – fully ready for the new generation of graphics cards and standards, without adapters and compromises.
• 2 x 600W 12V-2X6 PCI-E 5.1 connectors – allows powering the most powerful GPUs on the market, including future models with high peak loads.
• 9 x PCI-E 6+2pin and 3 x EPS 8-pin(4+4) – ideal for multiple graphics cards, additional cards, and enthusiast motherboards with more CPU power supply.
• 8 x SATA and 8 x 4-pin Molex – enough connectors for many SSDs/HDDs, fan controllers, and older peripherals.
• Modular design and 140mm fan – easier cable management, better airflow, and more comfortable noise levels.
• Active PFC and input 100–240 VAC – stable operation across a wide range of mains voltage, suitable for various electrical installations.
• Dimensions 85 x 150 x 200 mm in black – standard ATX width and height with a longer body, requiring a more spacious case.
• Warranty 120 months – 10 years of peace of mind for one of the most critical components in your system.

Who it's suitable for

This power supply is for enthusiasts, high-end gaming machines, workstations, and builds with future upgrades to top-tier GPUs. It is also suitable if you want to keep the power supply away from its maximum capacity for less noise and longer life. It is not the most sensible choice for budget or compact builds, where 1500W and the length of 200 mm are outright overkill.

The strongest aspect here is the combination of massive power, 80+ Platinum efficiency, and full modern connectivity (ATX 3.1, PCIe 5.1), backed by a 10-year warranty – a power supply you can confidently plan for several generations of upgrades ahead.
