PSU super mistake on tx750w

post #1 of 5
Thread Starter 
First of all I know nothing about computers. I got a pretty decent hand me down gaming computer. Antec 900 case and some good stuff, not sure sure what exactly (please tell me how I could find out what hardware I have). THE PROBLEM: my uncle is a heavy gamer and heavy smoker, so in my attempt to clean out computer to remove smell I took apart the psu corsair tx750w (yes, ignoring the warranty warning label). I broke the fan connection soldering trying to remove the case (I shoud have removed the fan screws first).

Before my questions I have to say I am not a gamer, I only intend to browse web, sync iphone, watch movies and maybe burn the occasional cd/dvd. So I am not sure if the fan not working is a big deal, considering all I read about the unit being so sophisticated.

1. Can I repair the connections with hot glue, or take it to repair shop to have them solder it back?

2. I had considered just replacing the fan itself with a 3 speed 140mm case fan and plugging it into one of the many connections not being used. Bad idea?

After reading about this psu I realized what a solid unit it is and that I made a big mistake. Oh and I am trying to do it on the CHEAP scale and not have to replace psu.

AND YES A GUY ON ANOTHER FORUM ALREADY TOLD ME HOW STUPID I WAS TO OPEN PSU.

If you can't solder the wire back, then I would have a repair shop do it for you.
Makes me happy!

Welcome to OCN smile.gif

One of the easiest ways to know what hardware you have: Download & run CPU-Z. Click on each tap of the app to see the different components you have.

The stock fan can be soldered back in. Not sure about the hot glue though.
I also see no problem with your 2nd option of plugging in a 14cm fan through the PSU's connections.

Here's how to put your rig in your sig:

Breaking a psu, if it is truly broken, it not the worst thing to worry about. You can have it replaced with a quality unit for around 100-150 dollars depending on your needs. At leat you did not damage the cpu, mobo, or gpu. Now if you would be so kind as to let us know what you are working with.

Where did the fan connection break, and exactly what broke? Clear, well-lit pictures will help a lot.

If you take it to a repair shop, be sure it's a TV or audio repair shop and not a computer shop because the technicians at the latter are rarely qualified to fix components, and their soldering can be really ugly.

The plastic part of the PLUG soldered to the circuit board isn't completely necessary, and the friction of the metal pins is enough to hold the fan socket in place.
If you have to straighten any pins, bend them slowly with long nose pliers. Any pin that's come loose has to be resoldered.

The plastic part of the SOCKET from the fan is more important but is easy to replace. Unlatch the metal connectors in it by poking them in the right places (probably the side) with a jeweler's screwdriver. Don't mix up the two wires because polarity matters (mark the circuit board with a red "+" for +12V, with a black "-" for ground).
