Elevate your system TO the next level.

Filters and enhances power coming from computer or almost any ‘audiophile grade’ power supply on the market. It will revitalize JCAT cards, or any other 5V component, and allow them to express their full potential.



  • State-of-the-art 5V DC / 2A power supply active filter and buffer
  • Designed and fine-tuned for best possible sound quality, OPTIMO nano buffers and filters typically very noisy 5V DC power supply coming from computer or so called ‘audiophile grade’ power supplies
  • 4x LT3045 state-of-the-art linear regulators working in parallel to give 2A output. The OPTIMO nano was designed with JCAT USB and Ethernet cards in mind which require around 2A from power supply.
  • Features linear low impedance output stage based on the design of JCAT flagship linear power supplies
  • Input voltage is filtered by active stage and buffered on top quality low impedance audiophile capacitors from Japan, vastly improving dynamic response
  • Comes standard with dual-lead high-quality teflon insulated, silver plated 18AWG DC cables. Output connectors can be customized to match customer’s device. (only 5V devices are supported)
  • Plug & Play
  • Superb build quality: 70um gold plated PCB, highest quality industrial grade components, gold-plated connectors from MOLEX
  • Design optimized for low impedance and short signal path
  • Features multiple protection mechanisms to guarantee safe and trouble-free operation for many years

JCAT Nano sounds like the grunt you get from a large Class A muscle amp… it is more easily able to fully flesh out the performance.Gavin, a customer


OPTIMO nano review


Who is the OPTIMO nano for?

For audiophiles looking for serious sound quality improvement who:

a) don’t have a linear power supply tuned for best sound quality to power JCAT cards, or SSD.

b) don’t want to invest in INITIO, OPTIMO DUO or OPTIMO S ATX power supplies.

c) already have an ‘audiophile grade’ PSU and want to improve it.

d) don’t have room for adding an external power supply – OPTIMO nano is installed inside PC and takes virtually no space.

What kind of performance can I expect from using OPTIMO nano?

During development we tested many power supplies and we’ve seen noise levels even up to 30 – 40 mV. OPTIMO nano drives this into uV range – close to more or less not measurable value.

Below you can see the output from so called ‘HIFi PSU’:

How to install OPTIMO nano?

Simply connect between your computer (or external) power supply and the component (e.g. a USB Card):

OPTIMO nano connection scheme

    1. Connect LP4 molex cable from your computer PSU to the INPUT on the right side of OPTIMO nano.
    2. Use the included high-quality DC cable; connect LP4 molex to the OUTPUT connector of the OPTIMO nano on the left side.
      The other end of the DC cables goes into the component (e.g JCAT card, SSD or any other 5V component)
    3. You can put the OPTIMO nano loose inside PC enclosure or use the self-adhesive tape that is in the baseplate of the OPTIMO nano.


  1. Which devices can be powered by the OPTIMO nano?

  • All JCAT cards; USB Card FEMTO, NET Card FEMTO, USB Card XE & NET Card XE.
  • SSDs and HDDs (models using 5V voltage only).
  • Any other 5V / 2A device (with a custom cable you can request from JCAT when you place the order)

How many devices can I power with a single OPTIMO nano set?

1x JCAT card and 1x SSD OR 2x SSDs. Powering two JCAT cards requires two OPTIMO nano sets.
