KHACHIMO Power Supply For TDK-LAMBDA NV-175 175W NV1-350TT-C

SKU CH-6MD4-K1KNA

A 175 W ATX unit with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower 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 provides clean, consistent power and reduces coil whine
  • 175 W ATX power supply designed for TDK-LAMBDA NV-175 NV1-350TT-C compatibility

ATX 175W Gold Efficiency

This ATX power supply delivers 175W of continuous power with 80 PLUS Gold certified efficiency. It targets builders who need a compact, efficient unit for modern standby compatible systems. The resonant LLC topology with DC-to-DC conversion ensures clean, consistent power delivery for stable operation. It suits low-to-mid range builds prioritising efficiency and quiet performance.

Capacity And Headroom

The 175W rating comfortably handles entry-level processors, integrated graphics, and modest discrete cards under typical loads. High efficiency reduces waste heat and lowers overall system power draw during daily tasks. Headroom diminishes quickly with power-hungry CPUs or mid-to-high-end graphics cards under sustained load. It is not suited for builds requiring substantial power reserves for overclocking or multi-GPU configurations.

Upgrade Path And Value

This unit replaces older, lower-efficiency power supplies lacking modern standby support or semi-passive cooling. The jump is worthwhile when moving from a non-modular Bronze unit to gain Gold efficiency and zero RPM fan silence at low loads. Builders adding significantly more powerful components will need a higher-wattage replacement. It serves as a direct fit for compatible TDK-Lambda NV-175 applications requiring ATX form factor.

Questions about this item

Will the 175 W output and ATX form factor fit an older system that still uses a 24-pin motherboard connector?

The unit is an ATX-type supply rated at 175 W, so it matches the standard 24-pin motherboard connector and will physically install in legacy ATX cases.

How can I verify that the Zero RPM fan mode is actually silent during light loads?

With Modern Standby support the fan stays off at low and medium loads; you should hear no fan noise while the system is idle or in sleep.

Does the package include the 24-pin ATX cable and the 4-pin CPU power lead required for a standard build?

As an ATX power supply it ships with the fixed 24-pin motherboard cable and the 4-pin CPU connector attached.
