ThPr78 Posted January 15, 2016 Share Posted January 15, 2016 Hello, on june 27th last year I bought an AX860 powersupply for my system. After letting the supply sit on my table for almost two months, I finally got around to install it in august. In late december, less than 4 months after starting to use PSU, it began to cause intermittent stability problems. And in just few days my 6 month warranty period would end. The system specs are in my profile, though I'll quickly summon them again: CPU: Intel i7-2600k Mainboard: Sapphire Pure Platinum Z77 GPU: Gigabyte GTX980 G1 Gaming SDD: 2x Samsung 850PRO 512GB HDD: 8x WD Green 4TB To the actual problem: With this configuration and the AX860 powering the system, things will only remain stable on idle. If the CPU is loaded (video encoding as RL example, Prime95 for artifical load) and/or if I'm playing games (Fallout 4, Witcher 3 as RL examples, Unigine Heaven 4.0 to simulate load) the system will blackscreen and crash after anything from 10 minutes to several hours of use. After swapping to an old 500W powersupply of a different manufacturer the crashes have vanished and the system is prime-stable and gaming-stable again. I do assume that the PSU -while still within specs on idle/low load- drops out of spec erratically/sporadically while under high load, causing the graphics card to blackscreen and crash the rest of the system. I'm situated in Iceland, so going through RMA on my own would incur relatively steep shipping fees and a waiting time of anything from 8-12 weeks, so I did return the unit to the computer store it was bought, who according to their own tests did not find anything wrong with it. I'm however skeptical of the abilities of a small computer store to properly diagnose and check a powersupply that only exhibits problems under certain conditions or high load. I'm therefor asking how to best proceed. Would an official letter from Corsair asking the store to replace the powersupply be an option? Or do I have to bite that bullet and enter into a lengthy and expensive RMA process?

Corsair Employees jonnyguru Posted January 15, 2016 Corsair Employees Share Posted January 15, 2016 You're in Iceland, but the RMA should be processed in the Netherlands. You really need to contact support and find out what your options are. Link to comment Share on other sites More sharing options...
