Bought a New PSU to power GTX 580.


Also added a LED strip to the case.


And last working for more than a month on my 7-channel Audio amp, and now it's finished. Some body work and colouring still left , but is working and sound's too good..

Forgot to add my 3 years old Subwoofer.
14inc X 14inc X 18inc Sealded Encloser made from 1/2 inc thick MFD board.
12inc - 4ohms - 800Watts Sub- drive
home-made 450 watts amp.
Still gives super powerfull bass.

Did you wire the led strip directly to the psu's 12v (yellow and black)
What's that red round thing in the middle near the switch?

You will get more crystal clear clarity on a Digital amp no?

Yes LED Strip runs on 12v from PSU and the red round thing is a fast blow fuse. In case of LED strip failure this fuse will protect other expensive hardware to go kaput with it.
Just to inform you that LED strip have a very high tendency to go on fire and they usually takes away power supply with them.

Digital amps are not liked very much around DIY audio community. And i personally like Class A-B amp.

fast low fuse? could you tell me its amp/rating and where could ifind one and how much it costs?
if led srtip fail how will the other expensive hardware to go kaput with it? will it short out the +ve and -ve 12 rails?
does a led strip go on fire? i have very little experience with them, then some people decorate houses ceiling with these, cars and bikes too, should there be a fuse too?
I am also thinking to hook to my pc as i have one small blue one

Fast blow fuse is a safety device used to prevent any type of damage to a product in a case of any part failure. Fast blow means that it will break the circuit power very fast in mil.seconds and a slow blow fuse take some time before breaking the power.

If you are using a LED strip in your pc with expensive hardware, i suggest investing Rs.20/- or 30/- in a fuse is not a big deal.

You can find fuse in different types shapes and rating in any local electronic shop. I am using approx. 1.5m length strip with consumes about one amp.. so a 1.5 amp 24 volts fuse was good for me.
You can use a multimeter for determining how much current is being consumed by your LED strip and getting a fuse with little more rating will do the job.

LED strips used in decoration are normally powered with a small power supply with some what 2-3 amp rating on 12 volts, but in PC you use your Computer PSU. A typical 400 watts psu gives 17 amps on 12volts and a 600w will give about 40 amp.. so that is a lot of current and can easily burn LED strip and wiring on fire.

Where did source those Rubycons from? Excellent as always..........Awesome.

I hate digital amplifiers its either Tube or class A or AB. And was that a Toroidal Transformer?

Caps from local shop (he made them available on my demand).

I also don't like sound of a Digital amps.. that's why these all are Solid state Class AB amps.

And the transformer is a low profile IE type, sourced it out of a dead old 2KV UPS from scrapyard and re-winded the secondary according to my need.
