puma Posted March 23, 2013 Share Posted March 23, 2013 Hi! A few days ago i received a new TX650w v2 ( model CP-9020038-EU ) after i returned a dead PSU (tx650w older version). After 30 min of installing the PSU and powering on the computer, there was a smell of something burning/too hot coming out of the PSU and i noticed the fan was not working. The same smell came out of the returned PSU some moments before burning out. I know this PSU has the new fanless mode, but the fan only spins at startup and even when i´m playing a game with >90% load on the gpu and >80% load on the cpu the fan never spins. I did the paperclip test and the PSU spins for 5secs only, then it stops, and the case fan keeps spinning. The volts on the rails seem ok (+3,31v, +5.04v,+12.09v -- in BIOS ). The system is stable, i´ve been using the PSU for about 5h, but it concerns me that the fan does not spin even at high loads and that weird smell of overheating doesn´t seem good. So, what should i do at this point? Return a brand new PSU, stress the cpu with prime 95 or something like that, do other tests? Is it wise to keep using the PC with the PSU like this? meanwhile, i´m using a fan on top of the PSU as a "substitute" to cool it. Any help? Thanks.

peanutz94 Posted March 24, 2013 Share Posted March 24, 2013 It's not uncommon for a new PSU to have that hot electronic smell for a couple of days. As long as the system is stable I would just use it and keep an eye on it. If it really bothers you, then it might be best to return it. But i don't think you'll have any issues.

puma Posted March 24, 2013 Author Share Posted March 24, 2013 Yes, other people also told me that in some cases it´s usual to have that kind of smell. Only thing it concerns me is that the last PSU i had to return, also started smelling like this and a few time after..."puffff!"... Returning the new PSU is the last thing i would like to do as it costs me a lot to send the package..:S Link to comment Share on other sites More sharing options...
puma Posted March 26, 2013 Author Share Posted March 26, 2013 So, Is it safe to test the PSU fan, using Prime 95 and Furmark? If not even these programs can activate the fan, should i return the PSU, or keep using it? Link to comment Share on other sites More sharing options...

If not even these programs can activate the fan, should i return the PSU, or keep using it? If the system is stable, then I don't see any reason why the PSU is faulty. Run Prime95 simultaneously with Furmark or 3DMark and find out if the system is going to be stable under heavy load. Link to comment Share on other sites More sharing options...
