MikkoBrokenPSU Posted December 20, 2020 Share Posted December 20, 2020 Hello! I have problems with my HX1200 booting into Windows. The motherboard Asrock Taichi x399 shows error code 62. I got this unit from warranty. The first one that got replaced was having loud bang noises when turned on, but atleast it booted and worked stable. The PSU serial number starts with: 203871, so maybe this is known problem: https://forum.corsair.com/forums/showthread.php?t=201807 But then again, why Corsair would send units with known defects to customers? Is there anything in PSU I could check? I am getting desperate, it is expensive to ship packages and I dont want to wait another 2 months. :(: Thanks, Mikko Link to comment Share on other sites More sharing options...
c-attack Posted December 21, 2020 Share Posted December 21, 2020 That appears to one of the lot codes affected. Contact Corsair Support so they can ship you a replacement. The recall notice is fairly recent. No idea when you got your RMA model. Link to comment Share on other sites More sharing options...
MikkoBrokenPSU Posted December 21, 2020 Author Share Posted December 21, 2020 I got the replacement last week after waiting weeks. All the HX1200 models were out-of-stock and when I finally got one, it was from defected series.:(: I already contacted support, no answer from there yet.

Warsheep Posted December 21, 2020 Share Posted December 21, 2020 I am in the same boat with you. They sent me a refurbished unit and that one is dead. Currently on hold trying to get this resolved, but it has not been a good experience. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted December 21, 2020 Corsair Employees Share Posted December 21, 2020 (edited) But then again, why Corsair would send units with known defects to customers? You got the PSU directly from Corsair? Corsair did not send "known bad units" to customers. Corsair actually recalled affected units from warehouses once the issue was found (about a month after manufacturer). The problem was not found immediately (i.e. at the factory) because it varies based on temperature. The colder the operating temperature, the less likely the HX1200 would start. If a RETAILER (e.g. Amazon, Alternate, Newegg, etc.) already had the product in stock before Corsair recalled that lot code, they would still send it to the customer. Corsair does not control retailer's inventory. They only control their own inventory. I am in the same boat with you. They sent me a refurbished unit and that one is dead. Currently on hold trying to get this resolved, but it has not been a good experience. That's surprising that it's dead. Refurbs are all tested thoroughly before shipped to customers. Did the refurb have the same lot code as the recalled product? Edited December 21, 2020 by jonnyguru Link to comment Share on other sites More sharing options...

Did the refurb have the same lot code as the recalled product? I don't see a lot code on the refurb. The only sticker is the one on the top of the unit and I don't see a lot code on there. I know I plugged it all in, flipped the switch, it then made a spark sound, and none of the lights on my motherboard turned on. I pressed the power button and nothing happened. I took it apart and put the unit with the cold boot issues back in and it went back to the multiple failed boots with eventually turning on when it warmed up. If you know where the lot code is or would like me to send you a picture of the sticker on the unit I can do that. Link to comment Share on other sites More sharing options...
MikkoBrokenPSU Posted December 21, 2020 Author Share Posted December 21, 2020 You got the PSU directly from Corsair? Corsair did not send "known bad units" to customers. The PSU was RMA from Corsair Netherlands, the serial number is within the date range and it doesn't work. Of course there could be other problems in the PSU.

S/N: 18067131 2018 06 7131 Seems like an older unit so not part of the recall, but doesn't explain why it's dead. Link to comment Share on other sites More sharing options...

No. That's actually MUCH older (which makes sense as it had to go back to Corsair for the refurb process). Link to comment Share on other sites More sharing options...
MikkoBrokenPSU Posted December 22, 2020 Author Share Posted December 22, 2020 I made some more testing and I actually made some progress. IF the GPU PCIe cable was in position 3 or 5 (as marked in the picture) the system booted to Windows. If position was 4 or 6, no luck. Also booting with cable in position 3 or 5 was not successful every time, it worked only every 2-3 time or something. I also tried booting with dual GPU with PCIe cables in both positions (3 and 5). Doesnt work. Link to comment Share on other sites More sharing options...

Doesnt work. I think it's coincidental. Since you're making boot attempts over and over, eventually it's going to work. The problem, that invoked the recall, was an LT431 used in the power good signal circuit whose value would change based on it's temperature. The colder it was, the lower the output voltage, which prevented the PSU from starting. Link to comment Share on other sites More sharing options...

The problem, that invoked the recall, was an LT431 used in the power good signal circuit whose value would change based on it's temperature. The colder it was, the lower the output voltage, which prevented the PSU from starting. Ok, it is probably coincidental. It now works also in position 6. I also tried to connect motherboard power cables to sockets 3-6 but no luck. The PSU starts, so its not the LT431 problem then. Thank you for your help.
