Naim Audio Supercap equivalent Power Supply Unit with high quality linear regulator boards

CHC-SuperCAP builds now come with the Mundorf capacitor upgrade fitted as standard. This can also be retrofitted to your existing unit if you own one of the older units.

The CHC-SuperCAP now uses Version 2.0 of our CHC-REG modules, and is built into the full-width version of our aluminium case.

The CHC-SuperCAP is a direct upgrade to the Naim Audio Supercap power supply - we use a technologically and sonically superior circuit design to surpass the performance of Naim's own PSU at a fraction of the cost! The CHC-SuperCAP uses a massive audio-grade toroidal transformer (ten times the size of the one used in our DC1 PSU!), high-speed Schottky rectifiers, large Nichicon KG capacitors and a modified version of our DC3 regulator modules. Housed in a smart brushed black case (with thick aluminium front, rear and side panels) and a simple central 'Naim green' LED, it is a perfect match for all Naim Audio equipment, old and new. The case measures 450mm wide, 280mm deep and 90mm high, making it a compact yet powerful upgrade for your equipment.

The CHC-SuperCAP is compatible in every way with all versions of the Naim Audio Supercap - but we have introduced many significant improvements, including but not limited to full-spec regulator boards for the digital supplies (not cheapened-down, simplified regulators like Naim use on their digital power supply rails), an improved supply to the auxiliary power outputs, and a few other miscellaneous improvements.

The CHC-SuperCAP does not come with any cables as standard, as the cables required depend upon the equipment you are powering (in addition, many Naim Audio items that require a Supercap PSU will come with the required cables anyway), but if desired we can supply the CHC-SuperCAP with a Burndy cable, 4 pin and 5 pin DIN cables to suit your own requirements. Please contact us for more details.


To power these units, we recommend the use of our PowerBlack IEC cable; ideally, a Naim system should be powered with a star-Earth mains sytem, as reommended by Naim themselves, such as our PowerBlack Distribution Block or our PowerBlack Hydra. An IEC cable is not supplied with the CHC-SuperCAP as standard, but we do offer a wide range of cables to suit any installation anywhere in the world.

Customer Testimonials


Luckily I got my Superline back earlier this week and it is now hooked up to the CHC-SuperCAP and is warming up nicely. When the CHC-SuperCAP was on my NAC282 preamp the sound was more open with more detail and a deeper bass, similar to your Dual CHC-CAP gives, but better. On the Superline it is very much better, giving very deep bass and lots of detail. I think it has even more to give yet, as it’s only been on a couple of days [TECHNICAL NOTE FROM CHC: the reservoir caps will take several weeks to 'form' to reach top performance].

Further Information


We have developed with our own in-house design for an extremely low noise power regulator circuit board, which has been met with rave reviews from our customers and beta testers. Our high-quality mains transformers are always specified far above the required power rating which ensures that they run cool, extending their lifespan and also meaning that they are much more capable of supplying large rushes of current when required, giving your music a much more open and expressive sound to it. This is all mounted inside an attractive case, with a power indicator LED fitted as standard - you can even choose the colour of the LED if you want.


We custom-build each power supply to suit your particular requirements - the CHC-SuperCAP can do anything that the Naim Supercap can do (and more, with its superior internal circuitry), so in all circumstances just use the CHC-SuperCAP in exactly the same way you would use a Naim Audio Supercap.
