Inside the PSU:

As we open this unit, please keep in mind that opening a Power Supply will completely void the warranty.  Not only that, but because of the large capacitors, you can suffer a serious electrical shock if you touch the wrong thing.  Please do not open your PSU to compare what the insides look like.  I'm a "trained" professional, meaning that I've got shocked a time or two and know where not to touch, and with that in mind and the smell of burning flesh in the air, click on the images below for a closer look.

It's amazing that the PSU is a bit roomy inside even though this is a 1200W unit in a standard ATX-sized case - with rounded corners.  Back when 1000W power supplies were new, they were very large and even with extended cases, they were crowded.  With the better power efficiency on these new "Gold" units, the cooling requirements are not as great companies can use smaller, more efficient components.  Overall, the layout is very clean - and both 12v rails use quality components. 

The cooling looks more than adequate for a 90+ rated PSU and during testing the internals never reached more than 52°C.  As you can see above, the main bulk of wires hits the rear modular backplane in a tidy bunch and the entire PSU is laid out very clean.
