An AX1200i for 55 free shipping and another socket 939, this time an ABIT with K8T800 Pro VIA chipset finally. I have 2 939's which are nforce3 pain in the backside for win98.
I would be wary of that AX1200i, I had two of them die on me from the well known fault they have with their OCP circuit, One was my original unit that lasted 8 months and then started tripping while in use, it took it another month to fully die from it before I sent it in for RMA. The second unit lasted 12 months before it too failed due to the very same fault, I never bothered RMAing that second unit and just trashed it and replaced it with a Seasonic 1000 Titanium Prime. Shame honestly as I do like Corsair PSUs but this model must have had a bad component from the factory.
There were a good number of users on their forums with the same issue with this particular model, whats telling is that they no longer make it and took it off the market very quickly once they acknowledged the issue.
Not saying to not use it, just be aware the AX1200i does have an issue with the OCP failing and it wouldn't be a reliable 24/7 PSU.
hmmm, i see. I've recieved the HX1200i and have it in my system at the moment. 9800 pro is not powering on but the cx430 allows it to on kt266. I'm giving it the beneift of the doubt atm. The voltages on the board look tighter on the motherboard readings compared to the cx430. i looked for alternative and ax1200i, was able to haggle the price down. thought it would be better built than hx1200i. If its a lemon, ebay is good at throwing it back to the seller on their dime. I dont have much tolerance for faulty components if its not listed as parts. thanks for the heads up
just a quick question, how did you load it? what was your setup. I'm only thinking of keeping it an AMD retro system for the 30A on the 5v rail. If its overcurrent protection on the 12v rail, not bothered
It was in my HEDT system, a Threadripper 2950X build with a 2080ti at the time, so it was being used at about 70 - 80% of its rated capacity which is perfectly normal, the symptoms of the OCP issue are it simply switching the entire system off when it trips the OCP, you then have to disconnect it from the wall and wait till it resets the circuit before it'll power up again. Note you dont even have to be using it heavily for the trip to occur, most times I was sitting at the desktop when it happened. (Other than one SSD drive there was nothing using the peripheral connectors, actually only had the one cable connected to that section on the PSU, no idea if the 5v and 12v are handled by the same OCP circuit controller)
Eventually it wont even reset as the circuit completely fails, no idea if its the IC that controls it that fails or if its heat related but we never got an explanation from Corsair about it, they simply took the model off the market and replaced all further RMAs with the HX model.
I should imagine it will be ok for a retro build that isnt under heavy or 24/7 use or even close to stressing the components of the PSU. Also there was zero damage to the PC and that system is still in use to this day.
