Compact 1U ATX Power Supply for Dense Builds

The KHACHIMO P1A-6250P is a 250W ATX unit built to the 1U form factor. It targets system integrators and enthusiasts assembling rack-mount servers, compact workstations or slim desktop chassis where vertical space is at a premium. Its 80 PLUS Gold certification confirms high efficiency across typical load ranges.

Fits Standard ATX Wiring in Shallow Chassis

The supply uses a conventional ATX pin-out so it connects directly to mainstream motherboards without adapter cables. Resonant LLC topology with DC-to-DC conversion delivers tight voltage regulation for modern low-power sleep states. Zero RPM fan mode stops the fan at low and medium loads, removing acoustic noise from idle systems.

Modern Standby Support Changes Sleep Behaviour

Modern Standby compatibility allows the platform to enter and exit connected sleep almost instantly while maintaining network presence. The same DC-to-DC architecture that enables this also reduces coil whine, so the acoustic benefit extends beyond the fan-stop feature. No extra software or configuration is required beyond a compatible motherboard and OS.

Questions about this item

How much continuous power can the 250W unit deliver before protection triggers?

The KHACHIMO 1U supply is rated for 250W continuous output, so its over-power protection will engage once that limit is exceeded.

How loud and hot does the P1A-6250P get during all-day operation?

At low and medium loads the Zero RPM Fan Mode stops the fan completely, while 80 PLUS Gold efficiency keeps waste heat and noise minimal even under sustained use.

What motherboard power connectors must my build already have for this PSU to work?

As an ATX-type unit it provides the standard 24-pin main connector plus the 4- or 8-pin CPU power lead required by modern motherboards.
