Riotoro announced the introduction of the three power supplies at Computex 2016: the Enigma 850W, Onyx 750W, and Onyx 650W. All three power supplies were developed in partnership with Great Wall and are based on new platforms designed to hit the sweet spot for practical real-world performance, reliability, and price. The Onyx line will initially be available in 650W and 750W models. The more up scale Enigma line will kick off with the 850W model.

The Riotoro Enigma 850W power supply is certified to comply with the 80 Plus Gold criteria for high efficiency, comes with semi-modular cables, and uses a quiet 140mm variable speed fan for cooling.

Is there any PSU with fan(s) capable of evicting the heat equivalent of its nominal power?

March 7, 2017 | 10:47 AM - Posted by Lee Garbutt

Yes, most any enthusiast grade PSU uses a fan capable of exhausting the waste heat generated at 100% load. You might also want to consider how much noise is generated at that level and the quality of the fan. A cheap fan that fails early will most likely take the PSU with it.

Literal rip-off of the legendary AX 850 of Corsair's (OEMed from SeaSonic), except this one's worse because it's not fully modular and probably has sub-par chokes.

As the reviewer pointed out, the Enigma 850W is made by the same OEM as The Corsair CS850M (not the AX850). And I would say that being semi modular is better than being fully modular. It's not like those 24 pin ATX and 4 pin CPU cables are optional. Not having the extra connectors on the front of the power supply just eliminates potential problems (oxidation, extra voltage drop, etc.) and gives a little more flexibility to the cables for easier routing.

A "silver award" for a product that has competition at it's price-point that is fully modular?

Then there is the "suspect quality" of some of the parts used in this device as noted by another more skillful reviewer on another web site.

Lee ought to retire before his "cream puff" reviews short him out.

Dude, who pissed in your Wheaties? I have to agree with the Silver award. It seems this power supply has enough good things going for it to earn a little recognition, but not ready for Gold. And as the reader above pointed out being fully modular is not an advantage, it's a disadvantage! I've been working in IT support for over 12 years so I know a little about PCs and power supplies.

The main reason manufacturers build fully modular power supplies is to save labor, which saves them money. It does not offer any advantage to the user. Modular connectors can be soldered on machines but fixed cables require hand soldering. A semi modular power supply offers the best combination of reliability and flexibility.

I for one appreciate the power supply reviews these guys provide and I hope they keep them coming for a long time.
