SAMA P850 White 850W 80 PLUS Platinum ATX 3.1 PCIe 5.1 Fully Modular Power Supply Unit – P0850-WHPFF001-US

Uncompromising Power and Efficiency

The SAMA P850 White 850W 80 PLUS Platinum Power Supply is engineered to meet the demanding needs of high-performance modern computing systems. Designed with pristine white aesthetics, it serves as the ultimate backbone for custom gaming rigs and workstation builds where reliability, aesthetic harmony, and high electrical efficiency are paramount. Delivering a robust 850 watts of continuous power, this unit effortlessly handles power spikes and sustained loads from high-end processors and modern graphics cards.

ATX 3.1 and PCIe 5.1 Future-Proof Architecture

Built to comply fully with the rigorous ATX 3.1 standards, the SAMA P850 White offers exceptional transient load response and stability. It features dedicated native PCIe 5.1 connectors, including a native 12V-2×6 (12+4) pin cable designed to directly supply modern high-performance GPUs without the clutter or risk of adapter cables. This forward-looking architecture ensures total compatibility with next-generation graphics cards, delivering future-proof reliability for elite gaming setups.

Elite 80 PLUS Platinum Efficiency

Achieving top-tier energy conversion, this power supply boasts an 80 PLUS Platinum certification, yielding over 92% efficiency at typical loads. This exceptional level of energy efficiency minimizes electricity waste, reduces operating temperatures, and lowers overall power consumption. The advanced electrical topology combines an Active Power Factor Correction (APFC) circuit with a Full Bridge LLC resonant converter, Synchronous Rectification (SR), and DC-to-DC design to guarantee ultra-stable voltage regulation under any workload condition.

Uncompromising Premium Components

Durability and longevity are at the core of the SAMA P850 White. The internal circuitry is built using 100% Japanese capacitors rated for high temperatures, ensuring consistent performance and resistance to thermal stress over years of continuous operation. Backed by an impressive 100,000-hour MTBF rating, this power supply guarantees long-term operational stability. Comprehensive industrial-grade electrical protections—including Over Temperature Protection (OTP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Surge Inrush Protection (SIP), and No Load Operation (NLO)—shield your valuable hardware components against unexpected electrical faults.

Whisper-Quiet Cooling and Fully Modular Design

Thermal management is expertly handled by a large 140mm cooling fan equipped with a durable Fluid Dynamic Bearing (FDB). This fan design delivers high airflow while maintaining whisper-quiet operation, intelligently adjusting speed to balance thermal performance and acoustics. The fully modular cabling system allows builders to connect only the cables required for their specific hardware configuration, drastically reducing cable clutter within the chassis, improving interior airflow, and achieving an impeccably clean white aesthetic build.
