FSP PTM Pro 1650W 80+ Platinum ATX 3.1 Fully Modular Power Supply ( 1650W )

The FSP PTM Pro 1650W (model HPT2-1650M) is a fully modular ATX power supply built to meet the demands of high-performance desktop systems. Certified to the ATX12V V3.1 and EPS12V V2.92 standards, it is designed for next-generation hardware that places substantial and transient power demands on the PSU, including platforms running the latest discrete graphics cards via a native PCIe Gen 5 connector. At its core, the PTM Pro 1650W achieves ≥94% efficiency at typical load under its 80 Plus Platinum certification, meaning less energy is wasted as heat during operation and your running costs are lower compared with less efficient units. The LLC Full-Bridge topology combined with a DC-to-DC module design for the +5V and +3.3V rails keeps voltage regulation within ±1% above 10% load change, delivering stable, clean power to sensitive components. A single +12V rail architecture simplifies power delivery and avoids compatibility issues common in multi-rail designs. The 135mm Fluid Dynamic Bearing (FDB) fan is engineered for both low noise and longevity. An Eco semi-fanless switch lets the fan remain completely off at loads below 30%, resulting in silent operation during everyday tasks and lighter workloads. When active, the FDB bearing sustains smooth, quiet airflow across demanding sessions. Installation is simplified through a fully modular cable system with a ribbon cable design, allowing builders to connect only the cables required and route them cleanly for improved airflow. The unit also features changeable side stickers for personalisation. Comprehensive protection circuitry covers over-current (OCP), over-voltage (OVP), over-power (OPP), short-circuit (SCP), over-temperature (OTP), and under-voltage (UVP) scenarios. Japanese electrolytic capacitors are used throughout the design, supporting the unit's 10-year manufacturer warranty.
