In Reply to: RE: Using 2 ATX PSUs?? posted by Julien43 on July 18, 2010 at 06:07:42
Hi Julien
>>It there anything problematic with completing the optimizations using one
power supply and then adding the second?
No, there shouldn't be any problem. I did just that.
>>Once the optimizations are complete should I defeat the PSU's cooling
fan? How do I accomplish that?
Yes, and if you are using Antec, just unplug the two pins socket and remove the four screws to physically remove the fan as well.
>>Can I snip off and insulate the rest of the wiring of the "Clean" PSU?
You should get a modular PSU. In this case, it would be easier to remove the unwanted cables. For me I de-soldered those not required anymore.
I had switched to linear supply for the CPU and hybrid linear and PICO PSU for the mobo, and I can say that switching back to SMPS makes my system not listenable.

Did you build up linear supplies or buy them? If you bought them, which ones?
THANKS!

Hi Greg
I am using 2 numbers, off the shelves linear power supply from Mouser Electronics.
Sola/Hevi-Duty SLD-12-6034-05T(12V & 5V) for CPU and other devices.
Sola/Hevi-Duty SLS-12-034T powering the 150W Pico for the mobo.
These are run on separate lines. Power inlet are through Bulgin IEC BZH01/Z0000/01(with switch and fuse). Used of these power inlets with Hi-Fi tuning fuses yield a better sound than direct connection to wall socket , the most evident was the tactile sensation in the bass not previously encountered.
These might not be the best but have to make do for the moment pending a better build. But I had ran these continuously for 40 hours without any problem.

Thanks. I've been looking at commercial linear supplies to use as the basis for an easy fully linear setup... WOAH, these things are expensive!
While my home-built linears don't have much less cost in materials, I can use very premium parts (Jensen 4-pole capacitors, good soft-recovery diodes) in them... and my experiences so far strongly say that sound quality is related to the quality of the supply and it's parts.
I was surprised when I heard the sonic signature I associate with various capacitor types (Elna Silmec, Panasonic FM and FC) when they were used on either the computer supplies or the 'dirty' (harddrive, USB, and screen) supplies. I don't have an explanation for this, but the sonic results were clear.
Still, a commercial linear setup may useful.
