## Long description

FSP VITA-850BD-B is an 850 W ATX power supply designed for desktop PCs. It supports the ATX 3.1 specification with 200% power excursion capability, a single powerful +12V rail and DC‑to‑DC design for the +5V and +3.3V lines. The unit uses a 120 mm cooling fan, premium flat black cables and a 105°C Japanese bulk capacitor. With a compact 140 x 150 x 86 mm size and 80 PLUS Bronze efficiency, it aims to deliver stable power for current and future hardware.
Advantages
The ATX 3.1 readiness and 200% power excursion ensure headroom for peak loads and future upgrades. DC‑to‑DC conversion improves regulation and overall efficiency while the single +12V rail simplifies power delivery to CPUs and graphics cards. Premium flat black cables make routing easier in confined cases, and the 105°C Japanese bulk capacitor increases reliability under high temperature and voltage fluctuation conditions.
Suitable for
Desktop PC builds requiring up to 850 W continuous power
Systems with modern CPUs and discrete graphics cards
Compact or space‑constrained PC cases
Upgrades where ATX 3.1 support and strong peak power delivery are desired

How to use
Install the power supply into a compatible ATX case and connect the 20+4 pin ATX connector to the motherboard. Attach the provided CPU, SATA and Molex cables to corresponding devices according to their connectors. Ensure input voltage matches the local mains (200–240 V) and secure all cable connections before powering on the system. Allow adequate airflow around the 120 mm fan and route cables to avoid obstructing ventilation.
Usage recommendations
For stable operation, use this PSU in systems with total load not exceeding its rated 850 W and maintain case airflow to keep internal temperatures within specification. Periodically check cable connections and keep dust away from the fan to preserve longevity and performance.
