Nickjf20 Posted February 7, 2013 Share Posted February 7, 2013 Hi, So I'm on my third TX750M now and the latest replacement (Thanks for the quick shipping!) has exactly the same problem as the second - the fan twitches slightly but never starts under furmark/games and makes a buzzing noise as it does this. It doesn't run at boot either. I've noticed quite a few threads with the same problem. After the first replacement I really should have accepted Amazon's refund and gone with another make ... RMA #5535476 Link to comment Share on other sites More sharing options...
Nickjf20 Posted February 7, 2013 Author Share Posted February 7, 2013 Phoned up, and was told I needed to speak to technical support - there was no response in over 10 minutes on hold. Eventually it dumped me into voicemail at which point I hung up. I'll wait on your response here but I'm really not impressed. Link to comment Share on other sites More sharing options...
MacNB Posted February 8, 2013 Share Posted February 8, 2013 I got the same experience. However, I did not hang-up on the voicemail but left a clear message (name, phone #, case #, and details of the problem reported on the forum). Within 10 minutes, I received an email from tech support stating "We apologize for any inconvenience you have encountered with your Corsair product. We have received & approved your online RMA (Return Merchandise Authorization) request and will e-mail your confirmation RMA number along with return instructions within 24 hours." So leave a message and they will respond. I guess a little patience is required. Link to comment Share on other sites More sharing options...
Nickjf20 Posted February 8, 2013 Author Share Posted February 8, 2013 My point is that I have already had an RMA and it is still giving problems. I doubt a 4th replacement of the same model will help anything. What technical support can do I don't know. Link to comment Share on other sites More sharing options...
MacNB Posted February 8, 2013 Share Posted February 8, 2013 hmmm....I see. Fourth one ...wow. I am still waiting for the RMA number. Hope luck is on our side. Link to comment Share on other sites More sharing options...
Nickjf20 Posted February 8, 2013 Author Share Posted February 8, 2013 Yep, it's really starting to annoy me now as switching power supplies takes a few hours because I have to tear down the whole case to access the media shelf (the only downside of modifying a PowerMac G5!) Some may say I'm just being overly fussy, but I borrowed the TX750M (original fan always on version) my friend bought at the same time as me (I originally had the fan always on version too) and there's no buzzing, no grinding and no whine.

Nickjf20 Posted February 9, 2013 Author Share Posted February 9, 2013 The noise is driving me mad as it happens most of the time when the PC is being actively used for anything but heavy gaming. Thanks to this PSU, the PC is quieter when playing something intensive like BF3 as the fan finally clicks and the buzzing stops. There seem to be an awful lot of new threads appearing with the same problem I'm awaiting a response from RAM GUY Link to comment Share on other sites More sharing options...

Just waiting on the paid postage label now What are they sending you now ? BTW, I still have not got my RMA number let alone paid postage label after the RMA was approved :[pouts: Waited on the phone for 10 minutes..had to give up in the end Link to comment Share on other sites More sharing options...

BTW, I still have not got my RMA number let alone paid postage label after the RMA was approved :[pouts: Waited on the phone for 10 minutes..had to give up in the end They offered me a HX750 originally, but it wouldn't fit in my case (180mm vs 160mm) so they made an allowance and are sending an AX760 instead. I cannot fault the phone customer service at all I've emailed the RMA department asking for a single postage label to send back both TX750Ms at the same time so I'll see what they say.

psvsolttu Posted February 14, 2013 Share Posted February 14, 2013 Having the same problem.. Bought other brand PSU and now the noise is gone. Hopefully I don't have to receive third faulty piece as a replacement for my RMA Link to comment Share on other sites More sharing options...
Nickjf20 Posted February 15, 2013 Author Share Posted February 15, 2013 Fitted it now after a few hours (the joys of the PMac case) and it's all perfect. There's coil whine when the PC is switched off but nothing I can't live with. Received an email back saying both PSUs will have to be sent back as separate shipments but they completely avoided my question as to where the pre-paid labels have gone ... I'll ring up tomorrow.
