Hello, I am trying to decide what psu to get and was wondering how you put a new fan in a psu, like how you get power to it. Like do you buy a led fan and take off the molex connectors and get power from inside the psu. Any help/explanations would be good.

I would like to add that modding a PSU can be very dangerous because it requires opening it. If at all possible just buy a new PSU. The watts that run through a PSU can kick your A$$. Im just informing you, not trying to scare you.

It's not dangerous at all if you unplug it first (and not a lot of voltage anyway.)
Opening and cleaning a PSU should be part of everyone's pc dusting ritual anyway. I'm assuming you're talking about adding an additional fan, not just changing them out. Just strip the +12v and ground wire off a molex near to where it starts, take 3/4 pin connector off of fan, solder wires accordingly (+12 to +12, ground to ground), and heatshrink/hotglue whatever is exposed to prevent shorts. It'll probably take you all of 10 minutes to do, unless you're not good with a dremel when doing the fan hole. Hot wire the atx pins to test it outside the case in case of freak accident and *bam* extra fan, no danger to yourself.

It can still hold power that can hurt you even after you unplug it

I think you're thinking of monitors, because they can hold lethal amount of voltage for years. PSU's have transformers that will give you a much smaller and annoying, but not dangerous, amount of voltage. CRT monitors can hold voltage up to 200 times that of the input line in some components. But if you're that worried, just touch a ground wire to the capcitors to drain them.

But there's no reason to waste money when it's a really easy and safe mod to do. The extra fans just drain's more power (like 2W per fan) from the molexes, just like if you were to plug them in normally. And worst-case scenario, you mess up and buy a new one, so there's little to lose except a couple minutes of your time. How can you guys be overclockers without being modders as well?
