YFS Power Supplies

by Kevin OBrien on May 4th, 2015


A lot of folks are headed down the Mac Mini path. It's a great direction to head in when choosing a dedicated music server. The Mac Mini with its i7 quad-core Intel processor and maxed out RAM / SSD's, gives the end user one heck of a server at a great price. Then comes the mods. Our PS-12m and Internal Power Filter mod come at a cost. The YFS PS-12m does what we want it to but there's one caveat: it's relatively expensive at its asking price of $1,895 MSRP. Add our Mac Mini DIY power filter kit for $375 MSRP and then add a YFS PS-5 USB linear power supply for $695 MSRP to power your DAC's USB input receiver with a YFS 'Split' USB cable ($525 MSRP) and things can get out of hand pretty quickly.

What's our answer?

We drastically cut the expense of our YFS Mac Mini source component package by offering the PS-512 power supply. This unit is specifically designed to power the Mac Mini with 8 continuous Amps of audiophile grade power. The PS-512 can reach 12 Amps of peak power which is well over the stock Apple switcher (7 Amps peak). We did this while simultaneously adding a 5 Volt rail to the same box to power your 'Split' USB or other DC powered component of your choice. The PS-512 packs the PS-5 USB and the PS-12m into a single-box solution with an 'affordable' price tag of $1,095 MSRP. The PS-512 not only makes your music sound better but you'll get faster start-up and shut-down, a quicker responding machine, better video performance, and an overall better Mac Mini experience all the way around.

Can the PS-512 match the performance of the PS-12m and PS-5 USB on their own? No, it can't but unless you have a reference 'mega-buck' system, you probably won't hear the difference between the two solutions. If you do own a high-dollar reference system, by all means, go with the 2-box solution and know you're getting the best money can buy in terms of 'affordability' for a USB-based transport. If money is tight and audio is not your number one priority (or you just plain value your money) the PS-512 plus the YFS Internal Power Filter Mac Mini mod is the answer.

The PS-512 comes standard with a 30" umbilical that utilizes a quick-disconnect metal connector on the PS side and a Switchcraft locking 2.5mmx5.5mm DC barrel jack on the Mac Mini side. Our YFS Internal Power Filter is the perfect mate for our PS-512 and sports the Switchcraft female connector that mates perfectly with the PS-512. 

Please specify your mains voltage when ordering (115V / 230V) and allow 6 to 9 weeks for a UPS tracking number as all YFS products are made to order. We do our best to get all orders out in a timely manner but sometimes we run into busy times of the year. Please be patient and realize we're working as quickly as we can. Thank you for understanding.


Drop us a line and we'll gladly chat about what you'll notice between models, etc. Let us get you in touch with some past YFS customers to help you with your system decisions. We're here to help.

We are taking our first steps into 'affordable' high end audio... This is new territory.  We're open to suggestions as always. Don't hesitate to contact us with any questions.

Thanks for reading.

YFS PS-5 USB LINEAR DC POWER SUPPLY                                                                                                         

Our YFS 'Split' Ref USB interconnect needed a partner in crime so we figured why not pair it with a high quality 5 volt linear power supply with a female USB input on the rear? Sounds like a fair enough question to me. Why not? So we did.                                                                                                                                    

You can use this custom audiophile-grade linear power supply to enhance your current 'Y' USB cable experience from another brand. We encourage you to use our YFS Reference 'Split' USB but if you really don't want to, we're not going to force you to...

So what does it do already? This power supply allows you to feed your current USB enabled device (via your 'Y' or 'Split' USB cable) pure, audiophile-grade power to your USB input receiver. This translates to improved sound staging, a blacker background, and more "life-like" images. Better bass as well as clearer highs have also been reported. Your mileage will vary depending on your personal system.

The PS-5 takes the place of your computer's +5V USB power bus. This is never a bad idea. Check out our "list" of compatible DACs and SPDIF converters in our FAQ section of our site. So is it worth it? Ask our current PS-5 customers if you'd like... We can get you in touch with previous customers, just ask!

Our custom USB linear power supply is available in 115V and 230V. Please specify which voltage you need when contacting us. The YFS PS-5 uses a standard IEC connector for power. The YFS PS-5 is a CUSTOM built product, made by hand in Upstate NY, all the way down to the circuit boards, and we do not stock them.

Please allow 6 to 8 weeks for delivery after your order is placed. Add another possible two weeks if ordering from outside the United States for delivery reasons.

Thank you for understanding.

We're excited about the YFS PS-5. We hope you are too... Contact us for pricing and availability.

The linear DC power supply market wasn't big enough so we decided to add to it.  :-)  YFS now offers a custom linear DC power supply. We call them the YFS PS series. 5 Volt, 9 Volt, 12 Volt, 15 Volt, 18 Volt and any other output voltage DC power supply is now available to replace your existing wall-wart or brick power supply. Each unit will be made to order and can be shipped 4 weeks at the earliest after an order is placed.

The unit pictured here is our PS-18. It's a linear DC power supply with an output voltage of 18 Volts at 1 Amp and an input voltage of approximately 120 Volts. After looking inside a few other manufacturer's units who we won't name here, we were a little disappointed with what we saw and heard. (Especially for the price)  Below is one of the boards from a YFS PS-9 power supply. You can see it's not exactly a production piece...

Contact us for more details if you're interested in picking one up to mate with your existing gear to give your system a little extra kick. Below is the 1-meter umbilical for a YFS PS-18 with an optional locking 2.1mm inner diameter barrel jack. This particular cable will be hooked to a Zodiac DAC to provide power in place of the stock wall-wart power supply.

Just let us know what input and output voltages your equipment requires and we'll get you taken care of. Let us know the type of connector your equipment requires as well. If there's a connector out there, you can be sure there's a way to find it somewhere. Below is a transformer from a YFS PS-9.

 THANKS for reading and we look forward to hearing from you.
