I bought this FSP Aurum 750W power supply last year and it has lasted me less than 12 months. It looks like a short circuit because it's blowing the fuse of every power cable I connect to it. The PSU went out with a loud pop; luckily it didn't damage any other internal components (or maybe it did and I won't know until I see them dying early).

The unit's box says 5 years warranty. The seller I bought it from offers 3 and thinks otherwise. For them warranty "covers only manufacturing defects and excludes physical damage". A burnt smell I mentioned is proof of physical damage. Kind of contradictory: it's as if a manufacturing defect can never cause physical damage.

On my side: I've never opened the unit, nor performed modifications on any of the supplied connectors. The seller is reproaching me for not using the bundled power cable. Didn't have a choice; my country adopts British standards for sockets (i.e 3 hole) and the cable was European style. It's a local seller so he knows that damn well. And I don't see what damage a 3 pin cable with a 13A fuse can do to a power supply that boasts of having overcurrent/overvoltage protection and industrial grade components. (Industrial grade my ASS, I've never had a cheap 20$ PSU die after less than a year).

My question: is this a fair case for an RMA?

Firstly that PSU is cheap and low quality. (i think so)
Even the advertised wattage output of say 750 W is not deliverable.
But in your case they should give you an RMA at least.
I have owned several cheap PSU's in the past (Finally switched to seasonic) and they all dies on me too but they lasted at least 2.5 years or more , the one i have from a local brand still lasts me , and its been working for 4.5 years , but it makes a lot of noise.
Anyways , go to FSP website if they have one , just check their RMA policies , and what do they actually "cover" in physical warranty.
Drop them an email if they have a support service , follow up with them.
To me it looks fair enough to put an RMA application.
Even super cheap PSU manufacturers take care of such things.

Those fsp units aren't cheap junk. If the seller won't do anything then contact fsp and rma through them.

Thanks, yes it definitely wasn't cheap. It was almost 200$ when converting from local currency. The seller did in fact collect it from me (to run "tests") and gave me a sheet on which he mentioned "RMA". But said he didn't think it would qualify for one,despite his not being able to detect any signs of misuse. I handed over the box with all its original contents (PSU, extra connectors, manual). Let's see what happens now.

The damage is probably on the inside which you should NOT open as that will void the warranty. FSP will open it their facility and probably find something wrong with it.
