Donny5150 Posted September 26, 2020 Share Posted September 26, 2020 Hi all, Looking for some help on a new PSU I just bought. I am adding a new GPU to my PC (adding a Titan XP to my 2 x 1080 TI's) and have bought a new HX 1200 to replace my 2 year old RM1000x PSU, which works fine btw, just not enough juice. The problem is the PC won't boot after I've installed the PSU. I've tried it a few times now. The 1000 works fine, but the 1200 doesn't want to play ball. The Pc seems to get power for a few seconds then it resets itself and goes on this cycle until i turn it off. It doesn't get to BIOS. Here's a little video I took of it: [ame] [/ame] If anyone can give me any pointers I'd really appreciate it. What are the chances the PSU could be faulty? Thanks, Andrew.

Donny5150 Posted September 26, 2020 Author Share Posted September 26, 2020 yep, exactly the same. No changes, same cables and everything. Link to comment Share on other sites More sharing options...
LeDoyen Posted September 26, 2020 Share Posted September 26, 2020 Did you reuse the 24 pin cable from the RMx with the HXi ? From the compatibility table, they have a different pinout, could be that maybe ? https://www.corsair.com/fr/fr/psu-cable-compatibility Link to comment Share on other sites More sharing options...

Donny5150 Posted September 26, 2020 Author Share Posted September 26, 2020 Thanks for your replies guys. Did you watch the video clip? It does seem to be getting some sort of power but there's obviously something not right and the PSU is the only factor. Thanks. Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted September 26, 2020 Corsair Employee Share Posted September 26, 2020 Yes. Watched the video. It's acting like it's finding a short, but since nothing has changed but the PSU itself, it should just work. Link to comment Share on other sites More sharing options...
