This article covers ALIMENTATION CORSAIR HX1000 PRO PLATINUMCP-9020139-EU 3446.

Overview

The Corsair HX1000 Pro Platinum (model CP-9020139-EU) is a 1000W fully modular power supply unit with 80Plus Platinum certification, delivering high efficiency and stable power delivery for demanding PC builds. It has earned a strong reputation among enthusiasts and professionals for its reliability and performance. This PSU is widely available through major retailers including , making it accessible to builders worldwide. The 1000W capacity provides ample headroom for high-end components, including flagship GPUs and multi-GPU configurations. Corsair's commitment to quality is evident in the use of premium Japanese capacitors and a robust circuit design, ensuring long-term stability even under sustained heavy loads. The fully modular cable design simplifies installation and improves airflow within the case.

Compatibility Guide

The HX1000 Pro Platinum conforms to the standard ATX form factor, fitting most ATX and E-ATX cases. It provides two EPS12V connectors (4+4 pin each) for high-end motherboard CPU power requirements. For graphics cards, it offers six 6+2 pin PCIe connectors, covering most current GPUs. However, cards requiring a 12VHPWR connector (such as the RTX 4090) will need a separate adapter cable, as this PSU does not include a native 12VHPWR port. Storage and peripheral connectivity is generous, with 12 SATA connectors and 8 four-pin Molex connectors, supporting extensive drive arrays and additional devices.

Product Info

The HX1000 Pro Platinum achieves 80Plus Platinum efficiency, exceeding 92% at 50% load. Its single +12V rail design delivers up to 83.3A (1000W), ensuring clean and stable power to critical components. Positioned in the high-end segment, this PSU offers an excellent balance of efficiency and capacity at a more accessible price point than 80Plus Titanium models. It comes with a 10-year warranty (terms may vary by region), reflecting Corsair's confidence in its durability.

Best Use Cases

First, it is ideal for high-end gaming PCs. Pairing a Core i9 or Ryzen 9 processor with an RTX 4080 or 4090 graphics card demands a robust power supply, and the HX1000 Pro Platinum delivers with headroom to spare. Second, it suits creative workstations used for video editing, 3D rendering, or other sustained high-load tasks. The high efficiency reduces heat output, allowing the fan to run at lower speeds for quieter operation. Third, it is a great choice for users planning future upgrades. The 1000W capacity accommodates GPU swaps, additional storage, or even a second graphics card without needing a PSU replacement.

Things to Consider

This PSU is based on the ATX 2.4 standard, not the newer ATX 3.0/3.1. It lacks a native 12VHPWR connector, so an adapter is required for modern GPUs that use that interface. For mid-range builds (e.g., Core i5 + RTX 4060), 1000W is overkill. A 650W or 750W unit would be more cost-effective. The HX1000 Pro Platinum is best reserved for high-power configurations. Its physical depth of approximately 180mm may cause clearance issues in compact cases. Always verify case dimensions before purchase, especially for Mini-ITX or small Micro-ATX enclosures.
