Seasonic SS-400ET-F3

A 400 watt power supply featuring a quiet 120 mm fan is suitable for powerful home computers, or smaller servers. Powerful cooling increases the reliability of the power supply, ensures the perfect cooling of all its components, and effective overall ventilation of the computer cabinet.The source, of course, meets the PFC standard of low harmonic interference and re-emission to the grid.

The source is equipped with a PCI Express graphics card connector, two Serial ATA power connectors, and an ATX 2.3 motherboard power supply. There is therefore a 24-pin ATX connector (20 + 4) and one 4-pin connector. For the other peripherals, two conventional molex connectors are available and another one is dedicated to power floppy drives. Also included are two Serial ATA power connectors.
