JCAT Optimo S ATX power supply: 500W for audiophile computer systems

JCAT has opened a pre-order for the Optimo S ATX. It is “The World’s 1st truly 100% linear ATX power supply for high-end audiophiles.” – JCAT says. The JCAT Optimo S ATX is intended to replace their “weakest link” in audio-computer systems – a standard switching power supply. Information about the development of the JCAT Optimo ATX power system appeared back in September last year.

The Optimo S ATX is ready to deliver 500W of power and can handle a maximum load of 23A per bus. The system provides protection against short circuits, overloads, overheating, output voltage surges and interference in the power grid.

The JCAT Optimo S ATX power supply received a separate case measuring 43x13x50 cm and weighs 25kg. The set includes power cables for the PC motherboard, processor, floppy drives and expansion cards. In fact, the case contains separate linear regulators, the stabilizers of which operate in a controlled voltage mode without feedback.

Each Optimo S ATX power rail contains 11 low-impedance capacitors with a total capacity of 110,000μF. The transformers have been specially designed for this model. They received magnetic and electrical shielding, as well as vibration isolation from the body.
