Looking pretty hard at this for my mac mini.KECES
I have been planning to start this thread for a while, decided to finally do it.I started building a new audio PC this summer. It started like a somewhat standard PC, but has now morphed into a "project".So to start this thread, I'll describe how I went to linear power, removing the pico PS that I had been using.First off, here is the PC configurationCase Lian Li PC-C34F :Removed optical disk cage from right side (when facing the front of chassis) and disconnected/removed all chassis fans.Motherboard MSI H81-P33Processor Pentium G3258 53wHeatsink Scythe shuriken rev BDRAM Crucial CT25672BA1067 2GB 240 pin DIMM DDR3 ECC x 2Power supply Astron +12 and DIY +5 and +3.3 Power suppliesStorage Samsung SSD 240gb drive for music filesStorage Samsung SSD 64GB drive for OS or a Western Digital 16GB CF card on a CF to SATA adapter.Using this as my PC, I bought a couple of Astron linear, 12VDC power supplies, I used the RS-12A. This supplies the 12VDC.I built a 5VDC linear and a 3.3VDC linear. I also built in some switches for power sequencing.For all the details, you can read my blog here:http://randytsuch-audio.blogspot.com/2014/09/pc-built-for-audio-playback-2014.htmlAlthough I did run into a few problems, and made some mistakes along the way, it really wasn't that hard.And it seems to work fine. I finished the 3.3VDC power supply this weekend, and it powers up every time so far with no problems. With the heatsinks I used (oversized for the power), the regulators just get warm.When I get around to the next installment, I'll tell you how I modded a Silverstone PCIE to USB card.Oh, and IMHO, it sounds really good with full linear power. As I described in my blog, I did make some comprises, especially the use of walwarts for unregulated dc power, but even so there is no comparison to a normal PC PS.Randy
ot of discussion on Mac Mini PSU, db audio's Eric can tell you that the stock PSU doesn't respond to anything really. I've considered trying a filter for it, but it might be beyond saving.
Not sure what you mean here. Can you provide a link to db audio?
