Corsair SF Platinum CP-9020284-EU

Compact SFX format power supply with platinum certification and semi-passive cooling, created for powerful Small Form Factor systems during the era of popular compact builds. The SFF segment is experiencing a true renaissance — modern Mini-ITX cases have learned to accommodate even large graphics cards like the GeForce RTX 4080 with a PCB length of up to 330 mm and powerful processors with a 280-mm AIO, all while occupying less space on a desk than a gaming console.

Corsair SF Platinum is designed specifically for these usage scenarios, offering the power of a full-sized ATX supply in a compact form factor. The 80+ Platinum certification is critical for SFF builds — every efficiency percentage directly affects temperatures within the limited case volume. High efficiency reduces heat generation by 15-20% compared to gold models, allowing components to maintain comfortable temperatures even in a dense layout.

The 750 Watts on the +12V rail is enough for configurations with hardware like "RTX 4080 + Intel Core i7-14700K" or equivalent AMD and Radeon setups. Support for the latest ATX 3.1 standard ensures proper operation with the transient loads of modern GPUs without triggering protections, while the presence of PCI-E 5.0 eliminates the need for adapters when connecting a graphics card.

The semi-passive cooling system is especially valuable in compact systems — at low loads, the unit operates completely silently, not adding noise to the single case fan. Modular cables with shortened lengths are specially adapted for SFF cases, simplifying routing in confined spaces. Corsair's seven-year warranty emphasizes the high class of the device and the manufacturer's confidence in the reliability of its components.
