350W 1U Server Power Supply

This 350W 1U server power supply delivers 12V output for rack-mount systems. It accepts a 100-240V input range and carries an 80 PLUS certification. The unit is built for continuous operation in industrial and server environments.

Non-Modular 4PIN ATX Connection

The non-modular design provides a fixed 4PIN ATX connector for direct motherboard power. Its 1U form factor fits standard server chassis without occupying extra vertical space. Builders must ensure the chassis supports this fixed cable layout.

Sustained 301-400W Load Behaviour

Rated between 301W and 400W, the supply maintains stable 12V delivery under prolonged load rather than brief peaks. The 80 PLUS certification indicates verified efficiency during extended server duty cycles. It is not suited for systems requiring modular cabling or higher peak headroom.

Questions about this item

What limits sustained output before the 350 W rating is reached?

The unit is rated for 350 W continuous output; the 12 V rail delivers the full rated power within the 100-240 V input range.

How loud and hot does the FSP350-601U get during all-day operation?

The non-modular 1U design uses an internal fan that runs continuously; 80 PLUS certification indicates efficient conversion, limiting excess heat at up to 350 W load.

Which cables or connectors must my server already provide for this PSU to work?

The supply has a fixed 4-pin ATX connector; the server backplane must mate with that plug and accept the 1U form factor.
