ATX 1200W Power Supply

The KHACHIMO HRS1200-9000 is an ATX power supply rated at 1200W with a -48V 25A output. It targets builders assembling high-output workstations or servers that require this specific voltage rail. The unit carries 80 PLUS Gold certification for efficient power conversion.

Modern Standby and Zero RPM

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

ATX Form-Factor Constraints

The ATX form factor determines physical dimensions and connector layout, so builders must verify case clearance and cable routing space. The -48V 25A rail serves specialised equipment and is not a standard PC voltage, limiting general desktop use. Efficiency gains from Gold certification diminish at very light or peak loads.

Questions about this item

Will the -48 V 25 A rail on the HRS1200-9000 require any periodic maintenance or replacement?

The -48 V 25 A rail is a solid-state output with no moving parts, so it does not need scheduled maintenance or replacement under normal operation.

What is the first limit reached on the HRS1200-9000 during sustained full-load use?

The 1200 W total power rating is the first limit; the unit will protect itself if the combined load exceeds that figure.

How loud and hot does the HRS1200-9000 get when running all day?

Zero RPM Fan Mode keeps the fan off at low and medium loads for near-silent operation, while 80 PLUS Gold efficiency reduces waste heat and keeps temperatures lower.
