Cooler Master V550 SFX Gold: 2020 550W, fully modular 80+ Gold SFX PSU for SFF mid‑range builds; legacy model without native 12VHPWR.
Released November 16, 2020 as part of Cooler Master’s first V SFX Gold series (ATX 2.52 generation), the V550 SFX Gold brought the brand’s V‑series feature set to true SFX dimensions. Cooler Master now lists it under Legacy Products, indicating the original model has been retired.
Positioned as a high_end SFX unit, it exists to power compact builds that still want 80+ Gold efficiency and full‑modular cabling. At 550 W, it’s well‑suited to SFX/small‑form‑factor and mid‑range gaming PCs, with standard 6+2‑pin PCIe leads rather than a native 12VHPWR, and it includes an SFX‑to‑ATX bracket for flexible case fitment. A fluid‑dynamic‑bearing fan and a 10‑year warranty round out the package.
