  • TypeATX
  • Modern Standby compatibility for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • DC-to-DC conversion enables more energy efficient sleep states

350W ATX power supply for mainstream builds

This 350W ATX unit targets mainstream desktop systems that need reliable, efficient power without excess capacity. It suits office workstations, home PCs and light gaming rigs where a compact, quiet supply is preferred over high-wattage headroom.

80 PLUS Gold efficiency with Zero RPM fan mode

The supply meets 80 PLUS Gold certification, delivering high efficiency that reduces power draw, heat and noise. Its Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion keeps output clean and minimises coil whine for quieter daily operation.

Modern Standby support replaces older

The unit adds Modern Standby compatibility for extremely fast wake-from-sleep times and improved low-load efficiency. This upgrade is worthwhile when replacing an older supply that lacks Modern Standby support or Gold-class efficiency, especially in systems that spend long periods in sleep or idle states.

Questions about this item

What efficiency does the 80 PLUS Gold rating guarantee for this 350W ATX unit?

The 80 PLUS Gold certification means the PSR350-DN delivers at least 80 percent efficiency at typical loads, reducing power draw, heat and fan noise compared with lower-rated supplies.

Which ATX case dimensions and mounting points does the PSR350-DN fit?

As a standard ATX power supply, it uses the regular four-hole rear mounting pattern and fits any chassis designed for ATX-form-factor units.

How do I enable the Zero RPM fan mode on this supply?

Zero RPM mode activates automatically when the load is low or medium; the fan simply stops spinning until the internal temperature rises, so no BIOS or software setting is required.
