I had an seasonic x750 that died just a few months back.
They will ask you to ship the psu to them in taiwan,wasnt worth it for me so i just got a coolermaster gold v2 850,works perfectly so far . Though i might upgrade to rm 1000x ,but they are too expensive right now.
Old Rmx 2018 series is no longer in production , Now they 've launched RMx 2021 series which is good too.
Corsair RMx series Psu's are too good. I am using RM650x since last 4 yrs.
I also used RM850 for 20 days , which is now on sale. Corsair used Chinese capacitors in RM series unlike Japanese which comes with RMx series.
I didn't noticed any performance or quality difference. So this comparison with Japanese capacitor build is more psychological than real.
When company is confident in providing 10 years warranty I didn't bothered whether they used Chinese or Japanese capacitors. However for some other reasons this project failed and I dissembled my rig and almost everything is on sale.
Seasonic PSU are the best, remember those platinum fanless series.
@fastapifastdisks I know about Tirupati enterprises and seasonic but Cooler master isn't bad either.
It depends on the series you're buying. If considering the base or economy kind of series almost every brand is similar.
Anyways I have opened a ticket at Seasonic Taiwan. Let's see if they can help with the repair else I'll dispose the psu. Locally repaired psu may turned out to be risky to use for side projects or even to donate.
It 's good to try with Seasonic RMA, let's see what happens next.
