KHACHIMO R1S-1120V 1200W ATX supply

The KHACHIMO R1S-1120V is a 1200W ATX switching power supply listed by the manufacturer in March 2024. It is built for desktop systems that demand high continuous output. The unit is supplied new and tested working before shipment.

Who this suits and who should look elsewhere

This unit suits builders assembling multi-GPU workstations or servers that can use the full 1200W rating. Systems with a single mid-range graphics card or modest CPU will not utilise the available headroom. Buyers needing a lower-wattage ATX supply should consider a different model.

The specification that decides fit

The single deciding specification is the 1200W rated output combined with the ATX form factor. Verify that your case accepts a standard ATX power supply and that your component load justifies this wattage before purchasing.
