The PRIME 1300W 80 Plus Gold ATX Modular Power Supply from Seasonic Electronics helps users achieve a good balance of efficiency, performance, and power, while its wattage range makes it suitable for heavy gaming and overclocking. This power supply features a single +12V rail that delivers up to 1300W of power to 12 PCIe, 12 SATA, 5 molex, and other essential connectors. It is certified with an 80-PLUS Gold rating for efficient use of energy, while cooling is accomplished using an onboard 135mm fan with a fluid dynamic bearing. Other features include a modular, flat cable design, which helps improve airflow within the system by reducing the amount of unnecessary cables.

The PRIME Gold Series achieves 80 PLUS Gold certification with its 90% efficiency at 50% system load.

Seasonic's design keeps the output voltage within a very tight range, achieving under 0.5% load regulation, making this power supply a suitable choice for high-performance systems.

Seasonic's experience in designing silent and efficient power supplies on the market has translated into the development of Hybrid Mode, which helps enable users to keep the overall fan noise at a low level.

High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are reliable and generate less operating noise and heat than ball bearing fans. The lubrication of the bearing surface helps reduce friction and vibration and therefore lowers the overall power consumption. Due to the quieter rotations and its robust construction, this reliable fan technology also helps increase the lifespan of the fan.

When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.

Seasonic's engineers have implemented a design feature where instead of cables, the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.

Q: 5. What's the difference between SeaSonic Vertex and SeaSonic PRIME versions?

A: The SeaSonic Vertex line, like the SeaSonic Electronics Vertex GX-1200W 80-PLUS Gold PCIE5 Modular Power Supply, and the Prime line, is that the SeaSonic Vertex power supplies will all support ATX 3.0 compatibility, where as the other power supplies may vary in their ATX format.

Q: 6. What's the difference between SeaSonic Vertex and SeaSonic PRIME versions?

A: The main differences between the Seasonic Vertex and Seasonic Prime PSUs are that the Vertex line is ATX 3.0 certified with PCIe 5.0 power connectors while the Prime line, like the SeaSonic Electronics PRIME 1300W 80 Plus Gold ATX Modular Power Supply, have longer 12-year manufacturer warranties.

Q: 7. Is this fully modular???

A: This is fully modular you should use only the cables you need to reduce clutter and improve airflow for a better ventilated system.

Q: 8. Will this unit comes with a power cable (3-prong) that plugs into the wall outlet? Specs didn’t mention such cable.

A: Yes, this item comes with a (3-prong) power cable that would connect to the wall for power.

Q: 9. Why so many different models of the 850 W? They trying to trick us into buying the wrong one?

A: If you have any specific questions about the difference in efficiency ratings for power supplies, please reach out to us at pc@bhphotovideo.com with any questions.

Q: 10. To connect to an 8pin graphics card, do you use 2 of the 4 pins on a single PCI-e cable or 2 separate PCI-e cables?

A: To connect an 8-pin GPU to the SeaSonic Electronics FOCUS 850W 80 PLUS Gold ATX 12V Power Supply, you would use an 8-pin PCIe connector to connect one of the 8-pin PCIe connectors on the PSU. For higher-power graphics cards that require multiple PCIe connectors, the manufacturer recommends using multiple cables.
