Computer PS Upgrade (Fuse/IEC/Teflon Cap)

Today I successfully installed a PCB fuse holder into my computer’s power supply. The stock fuse had leads soldered to the ends that were then soldered directly to the PCB. It took careful work with the Dremel to widen the PCB inlets to accept the fuse holder and now I can roll fuses with ease. I’ll soon order an SR Black fuse to replace the stock fuse rated at 6.3 amps/250V (5 x 20mm).

The power supply used only 1 film cap and it was rated at 1uf that was replaced with an unused Aura-T teflon cap that was sitting idle on a shelf. The power supply will help burn in the cap. Hopefully, the cap improves the sound of my generic computer which is my main source of music. There are too many teflon caps currently burning in since the acquisition of a Conrad Johnson 150SE; therefore, it will be difficult to distinguish what exactly is attributing improvements or detriments to my system but I cannot complaint at this point because my system sounds good. Today’s soundstage is more holographic than yesterday’s. Let’s see what tomorrow brings.

I noticed that the power supply’s IEC inlet is easily replaceable. It will be replaced by an Oyaide Inlet R that is currently in my modified Running Springs Audio Haley. I plan for the Haley to use the Furutech FI-06 NCF IEC or possibly purchase another Oyaide Inlet R for the computer.

Has anyone else tweaked computer electronics and what was your experience?

Thank you fellas for the suggestions. I might try the Fidelizer software and SR ECT. I would like to give a suggestion to other DIY hobbyists to look into using tin or silver plated beryllium copper fuse clips from Littlefuse or Eaton Bussman as shown in the link below:

@gdnrbob 4 items were replaced in the second stage of mods so I can't say what exactly provided benefits if any. I think the AH fuse provided at least 85% of the improvement that resulted from this project judging from my previous experience with SR Black fuses.  

I believe I can hear the differences between the AH Platinum fuses vs. the SR Black fuses. The AH fuses are a bit forward sounding (in a good way) and that produces focused / solid images in the sound stage. The SR Black fuses do not sound as dense. The mid range and treble sound "delicate" or "light" (in a good way). Both of these fuses provide improvements to the sound stage and imaging which is very important to me and both of these fuses are in the upper echelon of system tweaks. 

I heard these differences when I first listened to my computer with the new AH fuse and especially after Friday night when I installed 2 AH fuses into my amp.

@c_avila1 
Have you reversed the fuses? Some say it makes a difference. Some say it is a result of better connection. Who knows...

I have a Power Supply project on deck fro my PC.  I am ordering an external power supply with the proper voltage outputs and emblicals and will remove the existing internal PS and add the external.  Much lower noise.  A linear, regulated PS.

OP, I suggest you consider using Audiophile Optimizer on top of Windows--especially Windows Server 2012 R2.  The program is offered with a 2 week trial.  The improvement to sound quality, especially when run in "core" mode, is unmistakeable and wonderful.  There is a sponsored forum about this on Computer Audiophile.

I recently purchased a new computer and performed the basic fuse mod where I installed a copper alloy fuse block and the new SR Blue fuse. This was definitely an upgrade. Background noise has dropped, images are slightly more 3D, and improved image focus. The fuse block that I used is shown in the link below:

I plan to replace a pair of .47uf ps filter caps with 1uf Aura-T teflon caps in the near future.
