Are broken PSU's of use to anyone?

[jbone]

.... like for example, do people with the know-how ever buy them to fix them up, or are they best discarded?

Reason I ask is that I have a 6-month old 1000W Tuniq PSU which has started whining under load. It's not horrible but I won't tolerate it. Tuniq is being a bunch of jerkoffs and after several weeks they have done nothing to help me despite being fully under warranty, and Newegg has proven to be precisely as helpless. This broken PSU is still sitting in my computer case with nowhere to go.

I'm going to buy a new PSU from Best Buy today to replace it but I'm not sure if it would be worth my time to try selling the broken one. I just have no idea if PSU's are something a tinkerer could fix. I guess it would make a good paperweight if I chop the wires off.

Could be only a sleeve fan noise.
Is your case clean if not I would blow it out while its running.

Broken? I got the impression it was just making some unwanted noise.

That it is... noises its not supposed to make. The high pitched wine can become a very loud screech under certain situations. To me that's broken. So basically, since Tuniq is not going to honor their warranty or even talk to me at all about it, I'm buying another one. (NOT from tuniq of course...) I'm just not sure what to do about this one... sell it to somebody lookin for a project or toss it.

does it make that noise when directly plugged into the wall? or just on ups?

So what are you not telling us???
Those PSU`s have a 3 year warranty.......did you open the PSU???

If NewEgg and Tuniq won`t help you then what did YOU do that keeps them from backing the 3 year warranty??

Well the problem is that Tuniq wont even REPLY to me at all! They do not have a phone number; I've sent countless emails to their support address with no results. They have not replied to ask me anything about the PSU, they have not provided any remedy or suggestions... its like they no longer exist. Its like they don't even know I've come to them with an issue at all. Complete and total silent treatment. How useful is a warranty if you can't do anything about it because the company ignores you?

When I went to Newegg a couple weeks back, they said "OK no problem, we'll contact them for you..." and well... nary a word from Newegg. Doesn't surprise me... Newegg is probably trying the same ineffective thing as I did. Emailing them. To this day, Tuniq still has not even acknowledged that I came to them with a warranty issue and clearly Newegg is having no luck either.

This is a cut-and-dry case of being screwed by a company advertising a warranty but not being there when you actually need their help on that warranty. It should not take almost 4 weeks now to get something taken care of... almost 4 weeks and not a peep out of them. I don't plan to wait forever. I'm gonna cut my losses, write Tuniq off as a fraud, and move on.

The PSU is completely untouched aside from when I installed it... I have done nothing to it aside from routine dusting via compressed air. It sat in my computer (a new build) for six months before it began acting up.

Don't assume he did anything wrong. The company might actually be the shits.
I had a DIMM of GEIL DDR memory that I bought at Fry's a couple years back. Around 6 -8 months after I bought it it failed. I emailed their support with no answer after a week. I then started emailing them everyday for an RMA. I must have sent a minimum of 50 emails over the course of 2 months. They never answered my email and there is and still is no phone number.

You can't send it back without an RMA and they won't give you one. The forum had numerous instances of people in the same boat as me. Their forum is now down. I ended up going to Fry's with all my unanswered emails to GEIL and a supervisor actually replaced the memory for me.

Now back to his problem. Tuniq could very well be cut from the same cloth as GEIL. Basically a POS company that wants to sell you stuff but will not honor their warranty.

Depending on how much you want for it, I may be interested. I'd like to crack it open and see what can be done with it.

You might e-mail the MOD for these forums amd ask him...he has contacts all over the world..maybe he has a suggestion or better yet a tele....

Also another person to ask would be Oklahoma Wolf who does reviews for Jonny`s former site...

Another place to ask might be the people over at hardCOP......

Good Luck~~

I guess that really depends on where you put them.

They're very easy and inexpensive to repair, unless an inductor (transformer, choke) fails, but even some transformers are interchangeable.

If you do crack it open to try a repair, be careful! That big cap in there can hold a rather high voltage.

<--- nailed by around 300V DC from a PSU primary cap.

superglue or pure silicone sealant on the windings of the coils in the supply should stop the sounds. It is caused by the coils vibrating

Reminds me of when I was showing a trainee how to replace a CRT . CRT are like HUGE capacitors . They can remain charged for months and months and contain anywhere from 2KVDC - 15KVDC at about 10uf capacitance. I showed him the proper process of using the HV probe , place the alligator clip on the metal frame and then use the probe to lift the anode cap off the tube and the internal resistor in the probe will bleed off the charge. So he did one in front of me and I thought he understood. I left the room and then about 30 minutes later heard what sound like someone had broken a window and a loud thud.
Ran to the room and he was on the floor, broken CRT beside him and a stunned look. He said I guess I didn't do it right that time ? He wasn't hurt it just scared him and he knocked the tube on the floor and fell back, he had this look of WOW on his face. I just laughed. We teased him about that for a long time .

I agree; It may be worth it to contact some reviewers (especially those who have reviewed Tuniq products) and see if they can get you in touch with the company.

I used to take the 6800 and 4700 uF caps that we used in our power supply circuitry for the airbag modules we developed to use with whatever circuits I was building (big caps are expensive!). I didn't take new ones, but I would clip them off the modules that were getting trashed. I never did buy my own O-Scope, or Sautering Iron (because I had nowhere to put them until just recently), and my current workplace has no available lab to use, so I don't really have a use for extra electrical equipment anymore. But computer PSU's have a lot of really useful components that can be used again. Check the caps for any visible signs of bulging before attempting to use for other functions though.

The capacitors can be fun to play with.

One day at work, I was there with my buddy during Christmas Break (so only a handfull of people were in the office). I decided it would be fun to see what would happen when I hooked up an electrolytic Capacitor backwards. I stuck a 6800 uF cap between a concrete wall and the Electrical Technician bench, hooked it up to a 100A DC Power Supply, and steadily increased the voltage. At first nothing happened, but after a while, the current suddenly went from 0 to 100A and I heard a noise that sounded like a shotgun blast from the Cap. It blew up and left shrapnel in the concrete wall. I am very happy I didn't just leave it in the open on the bench, or that Shrapnel might have been in me or my buddy. It was a fun experience though, and I am glad I tried it out.
