starlit_mandala Posted April 23, 2007 Share Posted April 23, 2007 Hi All, I've just bought a Corsair HX620W PSU to replace the no-name timebomb that came free with my case. I opted for the Corsair one as many reviewers and forum members have said that it was quiet, efficient and reliable, three factors that I rate highly. Having installed it this weekend, I can hear a reasonably faint clicking / ticking sound from the PSU. Having looked through the Corsair forums and having done some general Googling I've come accross several potential explanations for the ticking : 1) The ticking happens because the PSU is under a very low load and is actually a design feature prevalent in several branded PSUs. A very plausible explanation, and some people have eliminated the noise by adding more devices like hard disks or optical drives. My Corsair 620HX current powers an AMD Athlon 64 3200+, a Gigabyte GA-K8N-SLI mobo, a Gigabyte 7900GT gfx card with a Zalman cooler, a Western Digital Caviar HDD, a Soundblaster Xfi , 2 optical DVD drives , an Akasa EVO33 HSF and 4 case fans (3 80mm ones and 1 120mm one - all of them quiet Sharkoons and Acoustifans). I would have thought that would be enough to create a reasonable strain on the PSU to eliminate the noise. Can someone from Corsair please officially confirm that the ticking is a design feature ? I would have thought all those devices would give it a decent load. 2) The ticking is down to the sticker on top of the fan coming loose and if removed, the problem is sorted. Again a plausible solution. From what I could see, my one was OK, but I will check with a maglite tonight just in case. 3) The unit is faulty and needs to be RMA'd. This one contradicts the above two and causes some confusion , hence my request for a concrete confirmation as to whether the ticking IS a design feature or a defect. To the best of my knowledge none of the case fans are obstructed with anything like a loose wire and the Corsair 620HX is mounted at the top of my case (an Enermax Black Knight) with the PSU fan facing downwards. Any help is greatly appreciated as this ticking is doing my head in ! Many many thanks in advance. Igor Link to comment Share on other sites More sharing options...
