Luc0z Posted January 24, 2013 Share Posted January 24, 2013 I recently received a replacement power supply unit which replaced a faulty GS700. The problem with the GS700 was that the fan didn't spin and was seemingly power-surging according to my motherboard's surge protection. As of late, I have had no problems with power surges on this new TX750 and has been running fine. When I turn the PC on, however, the TX750 does not spin to full speed as my previous faulty GS700 did. I have noticed though that when playing BF3 for about 20 minutes, the back of the PSU feels warm and the fan is spinning but doesn't seem very loud. Right now the fan is not spinning but it looks like it's trying to. I don't seem to frequently get the same electrical buzzing noise from the TX750 as I did with the GS700 but the fan seems to move clockwise/counter-clockwise the tiniest bit when im not running any games for a decent amount of time. I'm simply wondering if this is normal and just an annoyance (such as coil whine; harmless but annoying) or if it is yet another faulty power supply. I really want to avoid another RMA, so thanks in advance for your help. Link to comment Share on other sites More sharing options...
peanutz94 Posted January 25, 2013 Share Posted January 25, 2013 Lucoz, your PSU is functioning just fine. It is completely fan less at low loads /temps. The fact that it does spin while gaming would also point towards a properly functioning PSU. In addition, it's also not an uncommon thing for the fan to twitch a little either and absolutely harmless.. As far as heat goes, almost all PSU's will be warm to the touch, but not so hot that you cant put your hand on it. When you convert AC to DC the byproduct is heat, so it will be warm. As long as everything is stable I wouldn't worry about it. Link to comment Share on other sites More sharing options...
Luc0z Posted January 25, 2013 Author Share Posted January 25, 2013 What a relief, thanks for the reply! It does occasionally seem to make a quieter noise similar to what my old GS700 did, but it's definitely not as noticeable now. It does blow out relatively warm air, however when it is not spinning it is actually not warm at all to touch, probably because it's really cold over here in Britain just now.
