FSP VITA GM Gold 850W ATX 3.1 Fully Modular Power Supply

The FSP VITA GM 850W is a fully modular ATX 3.1 power supply designed to meet the demanding power requirements of high-performance gaming rigs and professional workstations. Carrying the 80 PLUS Gold certification and Cybenetics Gold rating (Lambda A), it delivers efficiency of 90% or greater at typical load, translating to lower heat output, reduced energy waste, and quieter system operation overall. At the core of the VITA GM is an LLC resonant-converter topology paired with a synchronous rectifier, a design choice that minimises switching losses and maintains stable output voltage across varying load conditions. The +5V and 3.3V rails utilise a DC-to-DC circuit design to further stabilise output and safeguard sensitive system components. A single high-amperage +12V rail powers the entire platform, making it well suited to multi-GPU configurations and power-hungry processors. Connectivity is comprehensive and future-ready. The unit ships with one 20+4-pin motherboard connector, two CPU 4+4-pin cables, four PCIe 6+2-pin cables, and one PCIe 12V-2x6 cable for compatibility with the latest PCIe Gen 5.1 graphics cards. Four SATA and four Molex/SATA connectors round out the cable set. Because the design is fully modular, you attach only the cables you need, improving airflow and simplifying cable management inside your chassis. Cooling is handled by a 120 mm hydraulic bearing (HYB) fan, a type of bearing known for low noise and long operational life compared to sleeve-bearing alternatives. The compact 140 × 150 × 86 mm chassis — 140 mm in depth — fits space-constrained cases without sacrificing power delivery capability. Eight independent protection circuits safeguard your components: over-voltage (OVP), over-current (OCP), over-power (OPP), over-temperature (OTP), short-circuit (SCP), under-voltage (UVP), surge/inrush (SIP), and no-load operation (NLO). — Verified Specifications — Rated Output Power: 850 W Form Factor: ATX12V V3.1 / EPS 12V V2.92 80 PLUS Certification: Gold Cybenetics Certification: Gold (Lambda A) Efficiency: ≥90% at typical load Input Voltage: 100–240 V AC Input Current: 11–5.5 A Input Frequency: 50–60 Hz PFC: Active (≥0.9) Fan: 120 mm HYB (hydraulic bearing) Operating Temperature: Up to 40 °C Dimensions: 140 × 150 × 86 mm Connectors: 1× MB 20+4-pin, 2× CPU 4+4-pin, 4× PCIe 6+2-pin, 1× PCIe 12V-2x6, 4× SATA, 4× Molex/SATA Protections: OVP, OCP, OPP, OTP, SCP, UVP, SIP, NLO Warranty: 10 Years SKU: VITA-850GM
