froglegs Posted September 27, 2013 Share Posted September 27, 2013 About six month ago I purchased an ax760i for a new build. After a couple weeks of use the computer started to randomly power down. That PSU was eventually replaced with another ax760i. Everything was working great until today. My computer has randomly rebooted itself 3 times now today. There is no blue screen or error codes. I just hear the power supply click off and then a second or two later the computer starts back up. It doesn't seem to have anything to do with system load. The first two times I was playing a game but the third time I was just reading some info on a webpage. One thing I noticed is that all 3 times the computer rebooted, I had the ax760i fan set to default mode in corsair link (I usually set the fan to a manual % when I start the computer because the constant ramping up and down of the fan when set to default drives me nuts). Is it possible that a temp sensor in the PSU is faulty? If the PSU overheats does it reboot to protect itself? I can't remember for certain but I'm pretty sure when I was having this problem with my old ax760i, the computer would only power down (it wouldn't power back up by itself like it currently is). Is there anything else that could be causing this? I'd really appreciate any suggestions. Thanks Link to comment Share on other sites More sharing options...
THS Posted September 27, 2013 Share Posted September 27, 2013 This is happening to my HX1000W. Happened to the first one, had it replaced. Happening to the 2nd. The 3rd replacement Corsair sent is a total dud and wont even power the system on....I wonder if the issues are related... Link to comment Share on other sites More sharing options...
peanutz94 Posted September 27, 2013 Share Posted September 27, 2013 Is it possible that a temp sensor in the PSU is faulty? If the PSU overheats does it reboot to protect itself? No it wont and with the system just starting it's not going to use any where near enough power to cause it to overheat. You would basically have to be gaming with both your GPU's fired up to get the PSU to a temp where you would actually need the fan. I can't remember for certain but I'm pretty sure when I was having this problem with my old ax760i, the computer would only power down (it wouldn't power back up by itself like it currently is). Is there anything else that could be causing this? I'd really appreciate any suggestions. Sure, there is always the pssibility that other hardware could cause this or even software. Bad drivers , a bad MB, and so on. Really, the only way to diagnose this would be to try another PSU in your system. There is no blue screen or error codes.

The first two times I was playing a game but the third time I was just reading some info on a webpage. Have you made any other software changes to your system? Updating GPU drivers by chance? Any chance you know someone you could borrow a PSU from to test with? Or have a spare? Also what are your 3.3v,5v,and 12v rails reading in your BIOS?

My BIOS voltages are as follows: 3.3v = 3.264v 5v = 5.000v 12v = 12.000v I haven't changed anything else that I can think of. Since starting the fans back up manually (40% in corsair link) the computer hasn't restarted again. I'm gonna use the system for a few hours and if it doesn't crash, change the fan setting back to default and see what happens. Unfortunately I don't have another PSU that I can try. Anyway, I'm gonna try testing this out a bit more and see if the fan settings in corsair link recreate the problem. There aren't any known bugs in corsair link that can cause this behavior are there?

froglegs Posted September 28, 2013 Author Share Posted September 28, 2013 I think I've narrowed down the problem... I used my computer all day today with the fan mode in corsair link set manually to 40% and had no issues. The computer ran great regardless of what I was doing. A few minutes ago I changed the fan setting back to default mode (the fan only starts up when the PSU reaches a certain temp). Within 5 minutes of doing this the computer did the random restart. The computer was sitting idle on the desktop when this happened. What is going on here? Is the PSU faulty or is this a software bug? I also have an h100i and have corsair link plugged into the port on the h100i. There aren't any known bugs with the h100i and the ax760i are there? I'd really appreciate some help getting to the bottom of this. Thanks Link to comment Share on other sites More sharing options...
peanutz94 Posted September 28, 2013 Share Posted September 28, 2013 Right now I would have to say a software bug. Have you tried to completely remove all instances of CL and try reinstalling the software? Link to comment Share on other sites More sharing options...
Antuans Posted September 28, 2013 Share Posted September 28, 2013 Hi, i have same issue, sometimes PSU not power on again until disconnect plugin cable or all modular cable. Once time i got red led on self test... i suspect psu fail. Today PSU works well few minutes and shutdown suddenly, no more power on. Link to comment Share on other sites More sharing options...
peanutz94 Posted September 28, 2013 Share Posted September 28, 2013 Antuans your issue is a bit different than this one. Could you please start your own thread and explain all the steps you have taken to test your system as well as your system specs? Link to comment Share on other sites More sharing options...

froglegs Posted October 2, 2013 Author Share Posted October 2, 2013 I've played around with this for a couple days now and it's looking like there is some sort of bug in Corsair Link. I'm not sure if it only pops up with my combination of hardware or drivers or what. When I have Corsair Link uninstalled, everything seems to work fine. When Corsair Link is installed, I have to set fan speed to manual to prevent the random restarts. I tried uninstalling and reinstalling Corsair Link and nothing changed. Anybody have any other suggestions? Without Corsair Link the ax760i is just a waste of money over the ax760 (especially considering the obnoxious fan constantly spinning up and down).

froglegs Posted October 2, 2013 Author Share Posted October 2, 2013 I just got another random restart. This time I did NOT have Corsair Link installed. It appeared to be working fine for about a day but I guess I didn't give it long enough. It appears the only way I can keep these restarts from happening is to manually set the ax760i fan to run 100% of the time. Can somebody help me out here? Would this indicate that the PSU is defective? Could something be overheating in the PSU? Maybe something that doesn't have a temp sensor attached to it?

peanutz94 Posted October 2, 2013 Share Posted October 2, 2013 Froglegs at this point I would go ahead and request your RMA to have it replaced. I don't kow exactly where the issue would lie, because without the LINK software it should function just like any other PSU. What your seeing definitely isn't normal.

Thanks peanutz94, I appreciate all the help you've given me over the last couple days. I'm gonna mess around with it for a few more days and if I can't figure it out, I'm gonna give Corsair a call and see if maybe I can exchange the 760i for a plain 760. This is the second 760i I've had issues with so I'd rather just avoid it from here on out. Link to comment Share on other sites More sharing options...
froglegs Posted October 6, 2013 Author Share Posted October 6, 2013 I found a great deal on a Seasonic Platinum 660W PSU and decided to pick it up. I installed it Friday night and my computer has been running flawlessly ever since (knock on wood). It's looking like the problem was the ax760i after all. I'm starting to think it might have something to do with my combination of hardware and drivers because this is the second ax760i I've had problems with. Assuming the Seasonic continues to work, I think I'll just stick with it. All the hassle I've had with the ax760i just isn't worth it to me. In the interest of saying something positive though, all my other Corsair products (h100i, K70 keyboard and 550D case) have been absolutely fantastic. This K70 is the nicest keyboard I've ever used and the quality is absolutely fantastic. There is just something with the ax760i that doesn't agree with my system. Anyway, I'm wondering what my options are. Since I purchased the ax760i from newegg and not directly from Corsair (although my current ax760i is an RMA I received directly from Corsair) I'm assuming a refund is not an option correct? If I can't receive a refund is there any way I can receive a store credit instead? Or is my only option to RMA for another ax760i and then sell it? If somebody in the know (a Corsair rep maybe) could help me out I'd really appreciate it. Thanks Link to comment Share on other sites More sharing options...

Correct. They can not refund you money for a purchase not made directly from them. Or is my only option to RMA for another ax760i and then sell it? Thats entirely your decision. The only other thing that comes to mind would be your BIOS. Is it the latest one? That would be about the only other thing that could potentially keep this PSU from working on your board.

That would be about the only other thing that could potentially keep this PSU from working on your board. I'm using the latest BIOS prior to the new ones for Ivy Bridge-E (I've heard of them causing problems for some people so I figured since I didn't upgrade to Ivy-E, might as well stick with what I have). I guess I'll just RMA it and sell it or just save it for another built. Thanks again for all your help Link to comment Share on other sites More sharing options...
