At RazerCon 2021, Razer announced its broad entry into the market for PC components. Until now, the manufacturer from the USA only offered one housing and one RGB controller hub. In the future there will also be fans (controls), all-in-one water cooling and power supplies from Razer. Razer only mentions the AiO supplier by name.

Unsurprisingly, Asetek is behind it in this case as well. However, Razer does not provide details about the fans and power supplies when asked. However, the manufacturer Sea Sonic is probably behind the power supply, as the zero speed mode (“zero RPM”) offers the platform offered by Sea Sonic customers suggests – it is doubtful that this is an in-house development.

However, Razer was not only covered in advance when it came to partners. The press release consisted mainly of the familiar common places, images and first prizes. When asked by the editors, some basic specifications could be named.

Razer Kunai: fans with 120 or 140 mm

Razer's new Kunai fans are not the first to be marketed by the manufacturer. The housings of the Tomahawk series announced exactly a year ago were, however, still different in the classic square frame.

Model Razer Kunai 120 mm Razer Kunai 140 mm aRGB 18 LEDs 22 LEDs Storage hydrodynamic slide bearing Speed ​​500 to 2,200 rpm 500 to 1,600 rpm Air throughput 29.7 to 111.2 m³/h 58.6 to 137.7 m³/h Static pressure 0.15 to 2.47 mm WS 0.15 to 1.31 mm WS Volume 15 to 35 dBA 15 to 30 dBA Lifespan 60,000 hours Dimensions 120 mm (L) x 25 mm (W) x 120 mm (H) 140 mm (L) x 25 mm (W) x 140 mm (H) Weight 182 g 207 g Power 4-pin PWM

The fans offer 18 or 22 addressable aRGB -LED in a circular frame and rely on a hydrodynamic slide bearing that should ensure quiet operation.

In order to not only integrate the fans built into the system into Razer's Chroma ecosystem, but also to control them (depending on the temperature), Razer is also introducing the PWM Fan PC Controller with eight PWM connections .

Razer Hanbo: AiO with 240 or 360 mm

The AiO Hanbo supplied by Asetek will offer Razer in two versions: with two fans on a 240 mm radiator and with three fans on a 360 mm radiator. Unsurprisingly, the promise is high cooling performance with quiet operation. The fans on both models can be operated in the speed range from 800 to 2,800 rpm. The cooling block is made of copper. In addition to AMD AM4, all common sockets from Intel up to the new LGA 1700 for Alder Lake are supported.

For the future, Razer and Asetek will be exhibiting “completely new” AiO products of cooperation in prospect. It remains to be seen whether Razer will make these products stand out from the well-known Asetek standard.

Razer Katana: power supplies from 750 to 1,600 watts

A fan with an RGB ring is also part of Razer's Katana series of power supplies. The PSUs in the power range from 750 to 1,600 watts are fully modular and can let the 140 mm fan stop completely if the temperatures allow it. From 750 to 1,200 watts efficiency according to 80Plus Platinum is promised, the 1.6 kW variant is to come as a special model with 80Plus Titanium. The power supply units allow operation in single and multi-rail operation.

Availability and prices

In the USA, fans and fan hubs are available immediately, the AiO and the power pack should follow by the end of the year. In Europe, however, the new product range will not be available until the beginning of 2022, as the manufacturer explains when asked. The fans should cost 49.99 euros (120 mm) or 54.99 euros (140 mm), the fan control 54.99 euros. No prices are yet available for the power supplies and the AiO – not even for other markets.
