550 W 80 PLUS Power Supply

The Rosewill VNW550 delivers 550 W of continuous power for desktop builds. Its non-modular cable set includes a 20+4-pin main connector, two 4+4-pin CPU connectors, two 6+2-pin PCIe connectors and six SATA connectors. The unit measures 140 mm in length and fits small-form-factor cases. Active PFC and a single +12 V rail provide stable voltage across all loads.

Sustained Load Behaviour

A 120 mm FDB fan and large steel vents maintain airflow during extended operation. The five-protection suite (UVP, OVP, OPP, SCP, OCP) guards components when demand remains high. Hold-up time of 16 ms minimum keeps the system running through brief mains interruptions. DC-DC design on the +12 V rail ensures clean voltage delivery under continuous stress.

80 PLUS Efficiency Limits

The 80 PLUS White certification guarantees up to 80 % efficiency at typical loads. Efficiency drops below that threshold at very light or peak loads, so sustained high draw converts more input power to heat. The compact 140×150×86 mm chassis limits thermal mass, making case airflow important for long sessions. Non-modular cables add resistance that slightly reduces usable headroom at full rating.

Kysymyksiä tästä tuotteesta

How loud does the 120 mm FDB fan get when the 550 W unit runs all day?

The 120 mm FDB silent fan is designed for low-noise operation; the steel shell with large vents and optimized thermal control keeps airflow steady during continuous load.

Which cables are permanently attached since the PSU is non-modular?

Fixed cables include a 20+4-pin main connector, two 4+4-pin ATX12V/EPS12V connectors, two 6+2-pin PCI-E connectors, six SATA connectors and two 4-pin peripheral connectors.

Will the 140 mm long chassis fit alongside an older ATX motherboard that uses a 24-pin main power socket?

Yes, the 140 mm depth and 20+4-pin main connector match standard ATX dimensions, so it installs in older cases and works with legacy 24-pin motherboards.
