This SR7T was designed to be more than sufficient to power a Taiko DC / DC ATX board with the 19 VDC @ 10 Amps output, with a separate high current 12VDC @ 12 Amps for a direct to processor connection. If you look at the photo of the inside of the unit, you’ll see what is no doubt the largest transformer you’ve ever seen in a LPS. It is even much larger than the one that Taiko uses in its $27,000 Extreme Server. l have used it with a wide range of computer servers that I have had over the years, and it has sounded superb on everything from a NUC to a Taiko DIY Extreme with two Xenon Silver CPUs on one Asus server motherboard. As you may know, these LPSs are legendary for their ability to provide deep powerful bass, excellent tonality through the mid and top end, and extremely clean and extended highs. They are now quite literally “unobtanim” since Paul Hanes closed his businesses right after I bought this LPS. The only reason that I’m selling it is that I have recently been fortunate enough to buy Nenon’s Taiko Extreme, and I have no use for it anymore. I am an old retired audiophile who has been a long subscriber of AudiophileStyle since its inception. I am also a long time subscriber of Audiogon and DIY audio. My seller rating is no doubt 100% on all sites, but when I do get around to selling equipment, I usually sell it to my friends; so the number of my online sales is quite low.

The 12VDC cable is terminated with an 8 pin molex plug as is used for a motherboard EPS CPU power socket. the 19VDC cable is terminated with a 6 pin molex plug as is used for a Taiko or a HDPlex 800W DC / DC ATX. These are heavy gauge silver cables with the factory terminations. If you want, you can send me different terminations and I will install them for you.

There is a back panel selection of 115 or 230 VAC.

The molex cables that I made out of 2.5mm Angelique solid core wire were by far the most rigid and PITA I have ever encountered. The next set I am building are going to be built with 2.5mm Angelique stranded wire, which is reported to sound as robust as the solid core, but a bit more open, and definitely easier to pre-bend into to form fit in the chassis. I have built molex cables with 1.5mm Mundorf SIlver Gold solid core, and they had an absolutely exquisite middle and high end sound, but lacked the middle and low end “meat on the bones” sound quality of the 2.5mm solid core Angelique. I am told that the 2.5.mm Angelique stranded may have a sound quality that is a bit of a combination of both the SG and Angelique solid core wires. We will see.

Angelo’s recommendations are spot on. We are all very fortunate that he shares so much of his technique with us. I’m a bit of a perfectionist about these things, so learning to make molex cable connections with oversized wire turned out to be, like bending heat pipes, an PITA acquired skill that took me a bit of practice to perfect. If you do decide to build oversized wire molex cables, be very very careful to build them with the bends already in them, with pre-configured plug orientations before you connect them to the sockets.

Thanks for the report.

I was initially quite put off by the sticker shock and the shipping costs, but once I bit the bullet and got one installed in place of the Salingy Power active rectifier I had been using, I was immediately impressed with the SQ blacker background and the increase in resolution that emerged from it. Salingy has released a version 2 of the GaN, and I am building it into my next Nenon v3 build with Mugg Hi-B cut chokes and 2 banks of 6 Mundorf 33000uF MLytic AG caps in each. It will be interesting to see if there are significant differences in the SQ of version 1 vs version 2 of the GaN boards.

The only way to get such a picture would be to take the rightm side panel / heatsink off a DIY Extreme, and that is not something that I want to do. Believe me when I tell you that it is very very little space to work with in that particular part of the build. If you are going to use relatively large gage and stiff wire there, it is best to attach the wires to the plug so that they are bent as close to 90 degrees to the plug, and even then, you may not be able to plug or unplug that connection to the motherboard without taking off and putting back on the right side panel / heatsink. So far, I have used Neotech UP-OCC copper wires, Mundorf SG alloy wires, and Mundorf Angelique solid core wires, in the DIY Extemes I have built. The Mundorf Angelique stranded wire has been reported to have the some of both the open and extended high end of the AG, as well as the meat on the bones of the Angelique solid core. I am looking forward to using the Angelique stranded wire throughout my next build.

The quality of the wire going to the under the chassis, momentary switch doesn’t matter. i am planning to use Angelique stranded wire in the largest gages practical for all of the other connections in my latest V3 ULPS and DIY Extreme. The 24 pin connections are the most difficult to work out because of the very limited space to work with in between the motherboard socket, the passive cooling tubes, and the heatsink. I have used the 4 pin SATA socket on the Taiko DC / ATX card to power the USB and Network cards with very good results.

The under chassis push button switch is to be connected to the motherboard as shown in the motherboard’s manual. I don’t connect a back panel rocker switch but rather unplug the power from the IEC socket whenever I am going out of town and shut down the system entirely. I have used Angelique solid core wire throughout several V3 builds, but have heard good things about the Angelique stranded and am in the process of using that in my next two V3 builds.

Unless I am mistaken Angelo’s case is designed to perfectly fit either the DIY Extreme or the DIY Olympus builds. My plan is to install my DIY Extreme in it now, gaining better cooling and rigidity in the process. Someday, I’ll re-purpose the case for a DIY Olympus build.
