  • Cleaner, stable power delivery through resonant LLC and DC-to-DC topology
  • Compact 1U ATX form factor fits space-constrained server chassis

350W ATX power supply for compact builds

This 350W ATX unit fits 1U server chassis and small-form-factor PCs that require an FSP350-601UC replacement. It delivers 80 PLUS Gold efficiency and Modern Standby compatibility for fast wake times. Builders working with space-constrained enclosures will appreciate the high-efficiency design.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC topology paired with DC-to-DC conversion provides clean, consistent power across all rails. This architecture reduces coil whine and supports deeper, more energy-efficient sleep states. The layout frees up internal space by eliminating the need for bulky group-regulation circuitry found in older designs.

Zero RPM fan mode and Gold efficiency

At low and medium loads the cooling fan stops completely, enabling near-silent operation during typical desktop or idle workloads. 80 PLUS Gold certification ensures high efficiency, which lowers power draw, reduces waste heat and keeps temperatures down. The combined effect is quieter acoustics and cooler running components.

Questions about this item

How does the 350 W rating hold up during continuous full-load operation?

The 350 W unit is 80 PLUS Gold certified, so sustained output at rated load stays within the efficiency band that limits waste heat and keeps voltages stable.

What noise and heat levels should I expect when the supply runs all day?

Zero RPM fan mode stops the fan completely at low and medium loads, while the LLC resonant topology with DC-to-DC conversion cuts coil whine, giving near-silent operation and cooler temperatures under Gold-efficiency loads.

What existing hardware is required to use the Modern Standby feature?

A motherboard and CPU that support Modern Standby sleep states are needed for the fast wake-from-sleep and low-load efficiency benefits to function.
