305W ATX Power Supply

The KHACHIMO N305P-06 is a 305 watt ATX power supply built for desktop systems that need reliable, efficient power delivery. It suits office workstations, small-form-factor builds and upgrades where a compact, gold-rated unit is required.

Practical Limits of ATX 305W

At 305 watts the unit cannot support high-end discrete graphics cards or heavily overclocked processors. The ATX form factor fits standard cases, but the rated output restricts the platform to mainstream CPUs and integrated or low-power graphics.

Replaces Older Lower-Efficiency Units

This supply replaces older bronze or unrated units of similar wattage, adding 80 PLUS Gold efficiency, Modern Standby compatibility and a Zero RPM fan mode. The jump is worthwhile when faster wake times, lower idle power and near-silent operation at low loads matter.

Highlights

  • Modern Standby support gives near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC with DC-to-DC delivers clean, stable voltage
  • ATX form factor fits standard desktop cases

Questions about this item

Which 305W variant should I choose among the N305P-06, N255PD-00, L305P-00, L305P-01, N305P-01, H305P-01 and C284C?

All listed part numbers share the same 305W rating, ATX form factor, 80 PLUS Gold certification, Modern Standby support, Zero RPM fan mode and LLC resonant topology with DC-to-DC conversion; select the part number that matches your chassis or motherboard documentation.

What does the 305W rating mean for a typical desktop build?

The unit can continuously deliver up to 305 watts across its rails, making it suitable for mainstream systems with mid-range graphics cards and standard peripherals while maintaining Gold-level efficiency.

How does the ATX form factor limit installation options?

ATX dimensions fit standard ATX, micro-ATX and many mini-ITX cases that accept full-size power supplies; it will not fit slim or proprietary small-form-factor enclosures that require TFX or Flex-ATX units.
