KHACHIMO 12V 80A ATX Power Supply

This KHACHIMO unit delivers a 12V rail rated at 80A for DIY projects and car audio amplifier builds. It operates as a switching power supply with an ATX form factor and has been tested for basic function. The design targets builders who need a single high-current 12V source from a standard AC input. It is not suited for systems that require multiple independent voltage rails or full ATX connector sets.

1000W peak and 800W continuous limits

The supply offers a peak rating of 1000W and a continuous rating of 800W on the 12V output. Sustained loads above 800W will exceed the continuous specification and risk thermal shutdown or reduced lifespan. The 80A current ceiling on the 12V rail defines the hard limit for any connected amplifier or load. Builders planning extended high-power operation must stay within the 800W continuous envelope.

Questions about this item

Should I plan for the 1000 W peak or the 800 W continuous rating when sizing my build?

The 1000 W figure is the peak output the unit can reach briefly, while 800 W is the sustained power it can deliver continuously on the 12 V rail.

What does the 12 V 80 A rating tell me about real-world performance?

It means the single 12 V rail can supply up to 80 amps continuously, which equals the 800 W sustained capacity for components that draw from the 12 V line.
