450W 80 PLUS Gold 1U Flex PSU

This KHACHIMO unit delivers 450 watts through an ATX-compatible 1U form factor. It targets compact workstation and server builds where rack height is restricted. The 80 PLUS Gold rating ensures high efficiency across typical loads. It suits integrators who need reliable power in a slim enclosure.

Fits 1U chassis with ATX mounting

The supply occupies a single rack unit and uses resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility allows rapid wake-from-sleep transitions and deeper low-power states. A zero-RPM fan mode stops the fan at low and medium loads, reducing acoustic output. The design frees vertical space for denser component layouts.

Upgrade from lower-efficiency 1U units

Replacing a standard Bronze or unrated 1U supply cuts waste heat and lowers operating cost in always-on deployments. The jump is worthwhile when noise reduction matters, since the fan can remain idle during light workloads. It also benefits systems that rely on Modern Standby for instant resume. Builds needing higher wattage or redundant modules are not addressed by this model.

Questions about this item

How long can the 450W output run continuously before thermal limits engage?

The 80 PLUS Gold rating keeps efficiency high so the unit runs cooler, allowing sustained 450W delivery within its thermal design.

Does the Zero RPM fan mode stay off during all-day operation?

At low and medium loads the fan remains stopped; under heavier continuous load it spins up to maintain safe temperatures.

Which motherboard power connectors are required for this 1U supply?

It uses standard ATX main and CPU connectors plus a PCIe 6+2 pin for graphics, so your board must provide those sockets.
