LED mod PSU?

[St.Alia-Of-The-Knife]

So i decided to put some sound reactive LEDs around my subwoofer and my monitor. I bought the parts and got it all planned out but now i am wondering if my power supply is going to handle the extra wattage

Lemme explain:

I will be using around 100 red LEDs each pulling about 20mA. The LED strip is rated at 12v so i guess some of the LEDs are in series

Basically the setup will pull around maximum 2 amps on the 12v rail and my PSU (CM extreme Power plus 700w) can deliver 52A. But with all the components pulling on the 12v, will 2 amps be a significant draw?

(see my system specs)
I dont know if this is relevant but my video card reads ~12.25v idle and ~12.05v full load. Since PSU voltage isnt regulated so it drops with the load, how low can the voltage go?

A 700W PSU with 52A (624W) on the 12V rail and the setup in your specs and you worry about 2 amps for LEDs ?

A HD6850 is rated at 127W max. With OC on both of them, think 150W or so per card.
x2 and we're at 300W, or 25A on 12V on full GPU load.

The X4 955.. in the worst case scenario it's the 125W TDP version. Let's go nuts and assume a ridiculously unrealistic 200W with OC.
That's 500W, or 41.6A total at full load with the bogus CPU consumption above.

Those OC'd wattage figures are made up. They're probably considerably lower IRL (especially the CPU one)
About the voltage.. The ATX specs say the 12V rail has a 5% tolerance, i.e. 11.4V - 12.6V is OK.

Or maybe its just my OCD

Im just worried that i am pushing my PSU to the limit, its over a year old and i frequently leave my computer on for crunching/bitcoin mining

lol.. My computer is on almost 24/7 and has been since I built it 4 or so years ago.
I only shut it down/restart it when I absolutely have to.

Still on the original PSU from back then (see specs thingy).
And all that junk is running off of 30A max. (360W) on the 12V rail.. (PSU Label)

Have to say tough.. you're pushing the PSU a bit if everything (GPUs + CPU) is on full load, but even then it's still within what it's rated for, so no worries..

given that its probably all overclocked id say be carefull, as on start up the psu might get overloaded but if it has protection youll be ok anyway, it just wont boot, on start up the loading is higher

and also something to consider ,i use a Mcubed Tbalancer bigNg tm for fan controll , its good for 20-25 watts from each of its four channels and is also advertised and is a full light show controller

with software tweekable usb connectiveity mines in the case obv,
