Sama G650W 80 PLUS Gold Fully Modular ATX 3.1 Power Supply White – G0650-WHGFF001-US

Elevate Your White Build with ATX 3.1 & PCIe 5.1 Power Delivery

Construct the ultimate clean, high-performance aesthetic with the Sama G650W White power supply. Engineered to meet the stringent requirements of the advanced ATX 3.1 standard, this 650-watt unit delivers unparalleled stability and superior resilience against power spikes. For users wielding next-generation hardware, the PSU is equipped with a native, heat-resistant 12V-2×6 connector and included cable, granting it full PCIe 5.1 compliance out of the box. This direct pipeline safely powers modern graphics cards—such as the NVIDIA GeForce RTX 40 and 50 Series—while seamlessly handling sudden demands with a 2X total power excursion and an impressive 3X GPU power excursion tolerance.

80 PLUS Gold Efficiency Powered by Premium Components

Enjoy elite energy efficiency wrapped in a pristine white chassis. The Sama G650W holds the esteemed 80 PLUS Gold certification, achieving a highly impressive conversion efficiency of up to 91.15% at a 50% system load. This near-Platinum level of performance means less electricity is wasted as heat, resulting in lower thermal output and reduced energy costs. At the core of this robust power delivery system lies a premium main Japanese capacitor. Widely recognized for their durability and strict manufacturing tolerances, this high-grade capacitor ensures stable, ripple-free voltage regulation and significantly prolongs the overall lifespan of the unit, even under heavy computational workloads.

Intelligent Thermal Management and Silent FDB Cooling

Keep your system running cool without adding unwanted noise to your environment. The Sama G650W features an oversized 140mm ECO fan driven by an advanced Fluid Dynamic Bearing (FDB). This bearing type reduces internal friction to a minimum, ensuring incredibly quiet operation and lasting reliability. For a truly silent computing experience during everyday tasks or media consumption, the power supply utilizes intelligent temperature and load monitoring. The fan remains entirely motionless—producing zero decibels—whenever the system load is below 40% or the internal PSU temperature drops below 55°C. To further eliminate acoustic disturbances, each corner of the cooling fan is reinforced with circular shock-absorbing rubber pads that suppress chassis vibrations and wind-cutting noise.

Fully Modular Architecture with Industrial-Grade Protections

Achieve a flawless, clutter-free interior with the G650W’s fully modular cable design. By only connecting the cables essential to your specific hardware configuration, you drastically improve internal chassis airflow while perfectly complementing a white-themed PC build. The compact 150mm length guarantees high compatibility with a wide range of PC cases, from spacious ATX towers to more confined micro-ATX layouts. Furthermore, Sama has integrated a comprehensive suite of hardware protections to safeguard your valuable components. The unit is armed with Over Power Protection (OPP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Temperature Protection (OTP), Short Circuit Protection (SCP), Surge & Inrush Protection (SIP), and No Load Operation (NLO) defenses, all backed by a reassuring 5-year warranty.
