Seasonic PRIME PX-1600 PSU 1600W 80 Plus Platinum PCIe Gen 5 - SSR-1600PD2

Seasonic PRIME PX-1600 is a high-end ATX power supply with 1600W power and 80+ Platinum certification, aimed at serious gaming and workstation configurations with multi-core CPUs and high-end GPUs. This is a PSU that meets the modern standard ATX 3.0/3.1 - PCIe Gen 5.0/5.1 and is ready for the latest graphics cards with a 12VHPWR connector. The modular design gives you full control over the cables, while the active PFC and high efficiency of up to 92% help reduce losses and generate less heat. The combination of power and connectors makes it a serious choice for multi-GPU setups, multiple drives, and heavy overclocking.

What you get

With real 1600W and a DC 3.3/5/±12 V rail, you get stable power for systems with multiple graphics cards, many fans, and storage, without the PSU gasping under peak consumption. The two PCI-E Gen5 12VHPWR connectors and a total of 8 x PCI-Express 6+2 pin allow you to combine new and older GPUs without the need for dubious adapters. With 16 x SATA, plus SATA 3.3 V and Molex, you can easily power a large RAID array, many SSDs, fan hubs, and additional controllers. A 135mm FDB fan ensures that cooling is quiet and reliable even under prolonged load. Thanks to the input 100 - 240 VAC, the power supply operates stably over a wide range of mains voltage – suitable even for more noisy electrical installations.

• Power 1600W – sufficient for high-end configurations with top GPUs, powerful CPUs, and multiple peripherals without the risk of power shortage.
• 80+ Platinum efficiency up to 92% – less loss as heat, lower energy consumption, and more stable system behavior under load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – ready for the latest graphics cards and power peaks according to current standards.
• Two PCI-E Gen5 12VHPWR and 8 x PCI-Express 6+2 pin – flexible connectivity for a mix of modern and previous generation GPUs, without compromising on cables.
• 16 x SATA + SATA 3.3 V and 3 x Molex – convenience for systems with many SSDs/HDDs, RGB controllers, pumps, and fan hubs.
• Modular design – you connect only the necessary cables, which facilitates cable management and improves airflow in the case.
• 135mm FDB fan – reliable and quieter cooling, optimized for long-term operation under load.
• Active PFC and input 100 - 240 VAC – better power factor correction and stable operation across different electrical networks.

Who it is suitable for

This power supply is for enthusiasts building a high-end gaming machine, a workstation for 3D rendering, video editing, or other heavy productivity with one or more powerful graphics cards. It is also suitable for systems with many drives and additional controllers, where the total consumption easily exceeds standard PSU capabilities. If you are doing a budget build or a mid-range configuration with a more economical graphics card, this power may likely be excessive.

The strongest aspect of this model is the combination of huge capacity 1600W, modern ATX 3.0/3.1 standard, and a rich array of connectors, which gives you peace of mind that your configuration is covered for future upgrades.
