The Enermax REVOLUTION D.F. X 1200 W power supply offers plenty of capacity for all workloads, featuring RGB lighting, ATX 3.0 compatibility, and two 12VHPWR cables. Backed by a generous 10-year warranty, it presents a compelling value proposition at a competitive price of $110.

For the fan Enermax uses their own branded 120 mm dual ball bearing fan (PFERS-12H) rated at 2300 RPM and 12 V / 0.3 A. It is partially covered by a plastic cover to help direct the fresh air where it is needed the most.

How does that plastic cover exactly help? It actually reduces the airflow in some directions...

The fan should have been 140 mm with less blades with patterns to improve the airflow, static pressure, and noise characteristics..

That's exactly the idea with plastic covers on PSU fans. They want to direct the airflow in a very particular way.

Why?
From what I see, the plastic cover suffocates the fan.
If they want a part of the PSU to remain without any airflow, then design it the other way - use a smaller fan, and isolate the part that should remain fresh-air-less.

100$? Where is the catch? O_O

This decades-old PSU fan design principle seem to stick and will probably stick for longer. Seems like the benefits outweigh the disadvantages of blocking the fan partially with some more budget oriented designs, as the air is strictly pushed to the very back of the PSU, to then be forced traveling over as many PCB components and heatsinks as possible before coming out the back.
With some PSU designs, enabling a full unrestricted fan may create particular turbulences or otherwise have the air skip some parts deemed essential to cool.
This method is a way to create a sort of air duct in a cube box design. Forgive my novice Paint skills.

it's currently $150 on their website and on amazon via 3rd party
CCC says amazon never had it below $165 in FBA, currently out of stock

Just checked on amazon around here and it's 189€ at a discount, guess that's the catch after all =P
With that said though the 1050 Watt version is 120€ and realistically all you would need for most builds... I guess the question at that point becomes whether you want the extra power or something of a hight quality (supposedly) at aroun 850 Watt.

Not the first time SANR did this, here's a review of one their units in 2022.

AQIRYS Pulsar LS White 750 W Review

The AQIRYS Pulsar LS White 750 W has a nice exterior, matching white, fixed cables, and a cool model name. However, is that enough to make it stand out of the crowd in the 750 W 80 PLUS Bronze category where it has to face units like the Corsair CX750M, XPG Pylon 750, and Thermaltake Smart BM2...

the D.F. 2 1200w is on amazon for $107 but that's the non rgb version and if I recall may not have the same warranty (not 100% sure and too lazy to look it up)

Here's one from a PSU review done on TPU 19 years ago. The idea of redirecting air from fans in ATX power supplies is really as old as gaming and high power intended PSUs go.

I get the concept, that particular OEM seems to be fond of it

Here is another review done on TPU 17 years ago. The concept is like I say - smaller fan that blows directly where it's needed the most.

OCZ ProXStream 1000W Review

OCZ's ProXStream is an extremely capable power supply that offers up to 1000 Watts of output. As you would expect it comes with four PCI-E power connectors and is CrossFire/SLI ready. In our testing we come to the conclusion that this PSU will be able to power any system you could think of while...

It was also the noisiest fan in testing, cause it's small. Slapping a giant 140mm over the entire side really is the best option.

I've been using a Revolution 85+ in my main PC since 2010. Survived several upgrades, moves, power outages etc so far.
If they still have that quality they're pretty good.
