Fortunately it was guaranteed for 3 years and Ihave been useing it for a bit over 2 years. RMA process went very smoothly

It's a CORSAIR HX series 520W modular. (for those who may not know what modular is: cables are not already fitted permanently. They come in a separate bundle and you choose what cables you need to use, so only the necessary cables are used and clutter of cables inside the case is avoided)
This is the PSU that will be feeding my system until I finally built another PC.

Altough it's a 520 Watts PSU, however, it gives most of its poers to where it's actually needed. That's of course the 12V rails. It has 3x12V rails, with a total of 40 Amps on 12V rails. Total power output on 12V rails is 480Watts! So it gives to all important crucial parts a total of 480 Watts from its 520 Watts main total. Getting a 480 Watts power output on 12V channel can be expected from PSUs with much higher total power, say, from those which offer 700+Watts.
So, everything good so far, as it seems; except that all the (somewhat unavoidable) hassle of dismantling the old PSU, and installing the new one remains. Well, at least PCs are better than Game Consoles in this respect, too. Hassle or not, at least we can change parts in our PCs, whereas a broken down (or even an old) Game Console quite possibly finds itself in the garbage can.
Well, I'll post my impressions on this new PSU later. And due to this affair, I've had opportunity to go through the current PSUs and refresh my knowledge on the subject. so, I can try to help to a few questions on the subject if any arise meanwhile.
