Question Corsair tries to replace AX1200i with HX1200i. Should I accept?


Apr 12, 2020
Recently my computer started to shut down randomly. After shutting down, it tries to recover, which means I hear the fan sound and see mouse/keyboard lights for 1 second and it goes again, then it tries again like a loop.

I realized that, if I go to the case and play the motherboard cable's socket on PSU, the computer can start without any problem. So I thought it was cable contact failure, then I bought a new cable but the problem still continues. So the problem is with PSU's motherboard socket.

I contacted Corsair since they have 10 years warranty. After emailing them for a while, they accepted it is PSU failure and propose me to replace it with HX1200i. I think they don't have AX1200i in their stock right now, that's why they proposed to me for HX1200i. I don't know exactly what are the differences between the two PSUs, But AX1200i is $100 more expensive than HX1200i. And it writes "Digital ATX Power Supply" but I don't know what are the advantages of it.

I was going to refuse and demand AX1200i but after I searched online, I found that users say "24 pin cable connection wobbly. Loose connection." about AX1200i and "The connectors look solid. Enough connectors." for HX1200i. So that causes me to create a topic here to get your opinions.

Also, I don't know if I really need 1200W, maybe I can go with AX1000 or AX750 etc., and get a partial refund as well? Here is my build:

Both are platinum. Johnyguru mentioned something about cracked smt capacitor on the ax series whether that was your issue initially? Who knows. Ax is still their top of the line psu though and i have a 760w version of it that's still going after 5ish years. I think Hx series are sold more due to price and thus regularly built. Still, Hx is also solid, and will do you well regardless.

As for wattage. 1200w is excessive, but is it? Depends what you run. With rumours looming of high wattage 4090ti incoming from Nvidia needing 800w itself. Wouldn't be far off anyway if rumours are false. And if interested in lower tiered cards, just may want to hang on to 1200w model being offered since it's not costing you anything. The extra wattage be a safety net.
