The ultimate Power Supply Units for music servers (and other devices for cleaner power source)

[Crom]

I've just ordered a bunch of John Kenny's supercap psu's to try out. John's been a star over the years I've been into this hobby and I want to try out his latest product.

 

My order consisted of:

1 x 19v to replace bog standard SMPS on an Intel NUC (running roon server)

1 x 12v to try out instead of MPAudio HPULN powering a supermicro motherboard which is running HQ Player, or perhaps powering etherregen.

2 x 5v  to try out against various things: a) Some Paul Hynes regs that are currently powering 2 x bufallo IIIse-Pro boards, or b) a MPAudio HPULN powering JCAT network card,

 

...I'll report back!

Can anyone report on a good experience they have had upgrading the standard IEC inlet on their power supply to one of the Furutech rhodium options?

A question:  if I want to power my CPU directly and the TDP is 95w, how many amps does the PS need to have?  Is the answer >8A, or is it not so straightforward?

I was told that my 12V HDPlex can run the CPU alone at 5A. I am not sure what the minimum A in general. I believe numerous members have used some 5A PSU for CPU alone. It also depends on the CPU. I think u can check

with the manufacturer. Also isn’t true if u use a higher V you be able to run on a lower current?

Sorry what is U again?

Yes that’s where I got >8A, but it doesn’t answer my question. . . .

I haven't done that , but better still would be to hardwire a quality A.C. mains cable directly to the Input terminal of the PSU PCB using a grommet and a strain relief You would probably need to fashion a small metal plate to replace the IEC socket mounting area..

 For various reasons , IEC mans plugs and sockets can be a pain in the butt for long term reliability.

 I have suggested something similar recently to others wishing to do what you are suggesting, and also using boutique mains wiring between the IEC socket and PCB as well.

 As A DIY person ., I have also had long term reliability problems with typical IEC plugs and sockets that need to be plugged/unplugged occasionally, including my P.C..

This morning I went to turn on my W10/64 P.C. and nothing happened whatsoever. Both the ends of the A.C. cable were a tight fit  so initially I suspected that the P.Cs. SMPS had failed. 😟

 In desperation , I tried several plug/unplug cycles at both ends. Much to my relief, the P.C. was working again..😄

 As I said , both ends were a tight fit, needing some effort to unplug them, and the P.C. was fine last night.

Some reviews were posted for DXP-1A5DSC that could further improve the performance of SR4 / SR7 rails

Did anyone experiment with these similar kits by any chance?
