  In terms of Power supplies, Super Flower Leadex Gold 750W is getting excellent Ripple measurements, closing in on Linear PSUs while being super affordable and convenient:

I would consider it before spending top dollar on LPSU. 

Thanks for the tip.  Those ripple measures are impressive.  Is it fanless?
Where Can I buy it Amazon? New Egg?
 
PS It looks they are fan only - but have an Eco mode.  Fanless for me is a must - my objective is no moving parts - especially spinning motors.

If you look at the review you will see that below 300W there is practically zero noise. For reference, my cpu draws 17W, maybe the SSD and RAM a few more.... most likely you will never reach anywhere near 300W.
 
For me ripple is farm more important and these are indeed impressive specs. A friend bought it and was shocked at the upgrade vs off-the-shelf PSU.

Awesome find, thanks for sharing.  I'm going to check that out.

rb, just for reference.  I have a SeaSonic 1000 watt Plat PSU in my gaming computer.  It also has a "eco" mode, and 90% of the time the fan isn't even moving.  For what it's worth   I know it's a totally different PSU.  But odds are while there's not much load (playing music is essentially no load at all, really) the fan wouldn't even need to kick on.

Good info.  I suppose disabling the fan completely would be a fire hazard.  This SeaSonic has my eye - fanless, regulated DC power and cheap enough

PS Even cheaper!

I like the use of higher quality Polymer Alum PS caps.
 
One thought I had was doing a mod on one of these with very high quality Pannie FCs in the filtering position.  It would only cost $20 - increase the ripple filtering and they are rated to 105C.

Wait.. Wasn't it cheaper on Amazon?  Whoops, looked at wrong one.
 
Either way, that one does have decent ripple measurements and it's the best of the Seasonic Fanless options.  The other one listed here though, has ripple measurements that are significantly better.  For what that's worth.   Of course, I'm not exactly sure where to buy it at

Here's some other PSU options with outstanding ripple measurements.

They do have great ripple measurements, however in terms of price they are more expensive than a linear PSU (which would provide 2-3 mV of ripple) so really not sure about these..

I agree, they're pretty darn expensive.  I agree at their price might not be worth it.
 
Looks like all the EVGA SuperNOVA's are great.  Apparently the the whole line is made by Super Flower.

That one isn't soo expensive. 

 

[bwmarrin]

Here's the 750 http://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_750/9.html
 
It's not as good as the 850 though and only $10 bucks cheaper.

Thanks for the links to that website guys! 
 
Here is the review of the Sea Sonic I ordered - glad I went with the SS-520FL
http://www.techpowerup.com/reviews/Seasonic/SS-520FL/5.html
 

 Voltage regulation is also nothing less than great since all three major rails registered very low deviations. SS-520FL's 5V and 3.3V efficiency also managed to take the lead by beating out Corsair's high-end models that use digital control on those rails. As you can see, a top-notch design utilizing conventional components/methods can provide equally great or better performance than a DSP controlled design. The only downside of the SS-520FL's performance is its low PF at 20% load, which should exceed 0.9. However, a high PF is not that important to residential customers since they only pay for Real Power, not Reactive Power. Yet a high PF is still somewhat desirable because it would put less stress on the mains power grid.

 
I think this will fit the bill - the site goes into nice detail as to the components - those KZe, Haitachi's and Rubycons may be the first to go.

Rb2013,

I use seasonic with little to no noise for hometheater apllications. Also, if I understand correctly, your power requirements are almost nil relative to gaming PCs, eg. 750 to 1000 PSU to drive SLI video cards.

You should be very happy with the seasonic. Good pick!

Thanks!  Yes - music only servers - so I just use the on board graphics.  Right now both servers are iCore 5's - but down the road may go one of the ultra low heat Broadwell-U or possibly SkyLake iCore 3 equiv.
 
I may just keep this PS though - especailly if I mod it with upgraded utlra low ERS caps.

If you get good at this, I would totally buy one from you. (Too lazy to try building it myself.) Then again, unless you want to be labeled as a member of the trade, it would have to be only at the cost of parts, so maybe you wouldn't be willing to go that far. I would love to have a dedicated music server, but most of them are so expensive!
 
For what it's worth, I heard from many sources that Windows Server 2012 R2 Standard has the best sound quality.
