Two random questions: Safe to unscrew PSU? Dual display mean double GPU usage?

  1. I've got two random questions. I've got a old EZ Cool Watt (JSP-600) PSU however I've noticed that it's really loud and I was planning on replacing the 120 mm fan within the PSU. However I'm aware that there is a possibility of electrocution. Has anyone performed his task and how likely is the risk of getting a nasty shock.

This is my PSU, and as you can see someone attempted to replace the fan--- > http://www.techsupportforum.com/hardware-support/case-mod/251826-modifying-ezcool-s-atx-600jsp.html

  1. My other random question, I've got both my LCD monitor and CRT TV hooked up to my 9600 GT graphics card displaying a clone display. The monitor is connected via DVI and the TV is connected via S-video. How much extra burden am I putting on my GPU if I were to play a game e.g. Assassin Creed

Well it would be a good idea to flip the switch on the back to off and drain the power by holding in the power button for a few seconds.

I doubt it's any extra burden. It's just displaying two of the same images.

To be honest, it's not a psu I'd even consider using as they are inefficient and can cause serious damage to all your parts if/when they go.

I appreciate your honesty. I bought it about 2 years ago from a computer fair for £15 back when 600 watts was rare and l33t, it was a naive purchase. However I have to admit it has served me well and has never caused me any issues, it's just the fan that isn't 100% silent (although still somewhat quiet)

Edit:

1. that wont drain the power, they can hold power for months/years after not being used, you really should be careful when opening up a psu, and dont go poking any of the capacitors/coils etc with your fingers lol, the charge they can hold can do a lot of damage(kill)
That is what my lecture at university said. But I'm too cheap to buy a silent PSU! But I think I'm better off spending a little bit of cash than risking my health. I was looking at this PSU http://www.ebuyer.com/product/102993

BTW my budget is a maximum of £30 and the PSU has to be silent e.g. quieter than my other fans which operate at 17 DBA

2. it shouldnt put any(anything noticeable anyway) due to the low res that crt tv's display at. although i wouldnt see the point of it myself as you can barely read anything on a crt due to their low res anyway
