"This LDB fan is also dust-proof..."
I'm intrigued by this statement. How exactly does one make a fan dust-proof?
Yes, I was wondering about that.
I was also wondering why such a very standard capacity PSU wth so many flaws got 8.5 out of 10.
It's an extremely average product which is overpriced a little bit. Again, 8.5 out of 10? more like 6/10, in that it probably won't burn your house down and it supplies the currents/power/efficiency that it advertises. Basically, it's one-up from the unbranded PSUs when you buy a Dell PC from a large high-street chain. If you need a product to replace something like that, for this money, you either want a bit more wattage or a bit more efficiency, these days. Obviously you can't have both at this price, but I would expect
one, which would then serve one of two purposes:
1) If it was still 550W but had an 80+ platinum rating, then it would be a good choice for someone with a modern CPU and up to a mid-end brand new graphics card.
2) If it was 700W and dropped to an 80+ Silver rating, then it would be a good choice for someone who is on a strict budget but definitely wants to include a brand-new high-end graphics card.
This card seems to fit into a slot where neither similar platform is satisfied, so I can't see a reason to buy it, condisering you have been able to buy cheaper alternatives; or
marginally more expensive ones with considerably higher specifications/capabilities. This PSU seems to be in the capability range of the market where someone's unbranded, chain-store PSU has failed. In that market, if you have a limited budget, you can pay a relatively significant amount less for something
roughly the same, or if it's an emergency and you really are on a very limited budget, you can get something second-hand which will do the same job for half the price.
There is nothing impressive about this PSU. Giving it 8.5/10 implies that it's only a little bit short of excellent. Which it is not. It probably does the job adequately, whilst making label-claims like "3D-circuitry", which as you've said, meand daughter-board type PCBs sticking up from the main PCB in various places. At best that's a complete gimmick which might be aimed at people who have read about "3D (i.e. FIN-FET) transistors", or possibly vertically-stacked memory. At worst it's an excuse for a design which will restrict and/or misdirect (or even trap) airflow, coming from a very very average fan.
My score: 4.5/10. Does the job, probably, but you can get the same or better for less money.
Which would be pretty pointless unless something's wrong (or you're reviewing something so bad it's dangerous), but interesting.
