For the design it must be the most beautiful. Is it worth the money?
No.
Do you sit around and gaze in awe and wonder at the interior of your computer case? Or do you pay attention to what is happening on your monitor(s)?
it useless for dual-chamber chassis designs where the side of the power supply is not visible.
^^^This^^^ Or like many, if your case does not have a side panel window. Or like me, your computer sits in a cubby-hole compartment in the bottom of my desk.
I totally appreciate good aesthetics. No argument from me there. But practicality, at least IMO, is more important. Once the newness wears off, your "most beautiful" power supply becomes just what it really is, a power supply. You don't "need" a beautiful power supply. And you don't need an expensive Platinum (or especially Titanium) supply. It will take you
YEARS of use to make up the cost with energy savings to recover the extra money spent on that purchase cost compared to a quality "Gold" certified supply.
Many years, actually. You can do the math. The average cost of electricity in the US is just under $0.17 per kWh. The difference between Gold and Platinum at 50% and 100% loads is just 2%. That means if the computer is demanding 500W, the difference between Gold and Platinum is only ~10W - a little more than a nightlight. And the reality is, most computers sit closer to idle most of the time than near 100% load. Plus, most computers are "awake" less than 6 hours per day.
See for yourself. If you use
this calculator and assume 10W (which again, is a high estimate) at $0.17 per kWh, 6 hours per day, 10W consumes just $3.73 per year in electricity. So again, many many YEARS.
I'd rather use that money for more or faster RAM, a bigger GPU or faster CPU or nicer monitor, or bigger drives, or a juicy medium-rare porterhouse and baked potato at my favorite restaurant.
Frankly, IMO, a quality case sits quietly and discreetly off to the side and does NOT draw attention to itself. A beautiful interior is one where the components are neatly and efficiently arranged, tidy cable management ensures the cables are all tied back and out of the way of proper air flow. And there is not speck of dust to be seen.
