Seasonic PRIME PX-1600W Platinum
Seasonic PRIME PX-1600W Platinum
The Seasonic Prime PX-1600 Platinum ATX 3.1 computer power supply unit stably powers high-performance computer builds with a total output of 1600W and full support for the ATX 3.1 standard. The internal design uses exclusively Japanese capacitors certified up to 105°C, contributing to long-term reliability. Micro Tolerance Load Regulation technology keeps the voltage deviation below 0.5%, which supports the stability of the entire system even under extreme load. Fully modular cabling simplifies installation and reduces obstructions for optimal airflow inside the case.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the components in the computer. It is a good idea to use a web calculator to calculate the optimal power output based on your chosen components.
1600W power of the Seasonic Prime PX-1600 computer power supply
The total power output of 1600W provides ample reserve for workstations or gaming rigs equipped with multiple graphics cards and overclocked processors. Extensive connectivity is available, including three CPU 4+4pin connectors and eight PCIe 6+2pin connectors. Fully modular cabling makes organising cables in the case easier and helps maintain a clean interior without unnecessary obstructions to airflow. You only connect the cables that are essential for your configuration.
Fully modular Seasonic Prime PX-1600 power supply with ATX 3.1
The power supply is fully compatible with the ATX 3.1 standard and supports the PCIe 5.1 specification, making it ready for the high demands of modern components. The specification enables it to handle short-term power spikes that are typical for high-performance graphics cards. Two integrated 12V-2x6 (12VHPWR) connectors power graphics cards with high energy consumption and provide them with a stable energy supply.
80 PLUS Platinum efficiency
The 80 PLUS Platinum certification confirms the power supply's high efficiency, which reaches 92% at 50% load. This means a minimal amount of electrical energy is converted into waste heat. High efficiency reduces the generation of thermal load and limits overall electricity consumption. This makes the system's operation more economical and quieter, as the cooling system does not need to run at high speeds to dissipate heat.
Precise voltage regulation of the Seasonic Prime PX-1600 power supply
Micro Tolerance Load Regulation (MTLR) technology actively stabilises the output voltage regardless of the current system load. The extremely low output voltage deviation of under 0.5% supplies the connected components with a constant and clean power supply. This precision is crucial for the stability and reliability of sensitive components such as processors and graphics cards, especially during overclocking or in demanding applications.
Quiet and efficient cooling
A 135mm fan with a fluid dynamic bearing (FDB) handles the cooling. This bearing uses an oil film to reduce friction and operating noise, which also contributes to extending the fan's lifespan. Digital hybrid control keeps the fan idle at low loads (Zero RPM mode). The fan activates only when a set load is exceeded, supporting completely silent computer operation during normal work.
Comprehensive protection for the 1600W computer power supply
The power supply integrates a set of six key protection features. This comprehensive system protects connected components from damage due to unstable power or a hardware failure. It includes Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP).

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of PC power supplies. It gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
