Ax1200 3.3v

[ChronSyn]

Good morning,

I'm concerned about my AX1200 PSU. Round about 4 months ago, I noticed my system shutting off without warning regardless of system load. Prior to that, and right back to initial purchase, there'd been system crashes usually met with a plain black screen. The frequency of these was irregular. I had assumed it was a GPU issue (as I was using 3x GTX580's which were notorious for stability), but I'm now using a single GTX670 and still the issues remain. These issues have followed me through modest and sensible overclocking, and through stock settings on all components.

 

I'm housed in an 800D, and so I've had to use the extension cable that was provided in order for the 4+4 to reach the socket which means that there's 3 potential points for failure (PSU Socket, Adapter socket, and Motherboard socket). You've then got to consider the rather tight turn at the PSU socket end in order to feed it behind the motherboard tray (single the alignment of the grommets in the bottom chamber aren't really aimed at larger PSU's).

 

Regarding the 4-months ago situation; post-crash, BIOS was reporting very low 3.3V reading (around 2.6V IIRC). One post on here suggested reseating the 4+4 pin cable. I did that, and sure enough, it returned to 3.26V.

 

Just tonight, the same sort of crash happened again. System wasn't even under heavy load, I was just busy working on a software project when the system cut out.

 

3.3V reading was at around 2.7V, and again I reseated the 4+4 pin. However, now, it's sitting at 3.088V - 3.104V. I understand that it's still within spec, but I'm wondering whether this recurring problem would be covered under RMA. Even if it is, there's still the issue of being without a system until it's returned, and the costs to ship it back to Corsair.

 

I've had the PSU since March 2011 and it's been in usage for the majority of that time, though not always at peak load (typically, it might be under 'heavy load' for 30 hours a week though since moving to a single GPU, peak system load is closer to 450W, and low load for the rest of the time). Normally I'd return them to the supplier as they generally replace them within 48 hours and even cover shipping both ways, but being almost 2 years old, it's going to be outside their warranty range, and I'd be concerned that the issue may not make itself known in the time they're testing it anyway.

 

So, would this be covered under RMA? Would I have to go without a system while it's being processed, and would it be at cost to me to return it? Those last 2 points are the big ones (being without a system will definitely affect my projects and potentially affect OpenUniversity study starting very soon).

 

Regards.

Yes, it would be okay to RMA it. However if a second unit does the same thing then it is probably the connector on the MB causing it

Yes, you would be responsible for shipping it to them. and if you need a PSU in the mean time you can call CS and request an advanced RMA. But you will need to call CS to have that arranged.

sounds like the socket is vibrating loose over time so the 4+4 isnt makign a good contact, this is mostlikely caused if as you say there is pressure on it from the cable being bent to tightly in order to make it reach, i'd advise your best bet is to buy a longer 4+4 extension or to "mod" your case to remove the problem.

 

i apreaciate metal bending isnt everyones favourite option:laughing:

 

its also highly likely that you would experiance distortion of the 4+4 connector at the stressed point (weather thats the mobo connector or the extension to lead connection).

 

since i havent seen your particular pc i'm unsure on this but can you fix the cable so that a cable tie is taking the strain rather than any of the connectors ?

 

if you cna its possible you can get rid of the not making a full connection problem yourself just dont tie it to a heatsink "because its got good purchase point and it was in theright place" you might laugh but i have seen it done ...
