Razer is a well-known brand among PC gamers and users, it started as a peripheral manufacturer focused on keyboards and mouse but after years passed Razer expanded its inventory offerings. It soon started offering headphones and lately has branched into wider product lines like gaming chairs and protection masks.
It is not a big surprise that Razer is expanding into other branches of the PC industry. This time, however, it has revealed not one but three new hardware for your PC. Case fans, all in one liquid cooler and power supply.
There are not many details about the products themselves but one thing is one hundred percent confirmed, they come with Razer Chroma, all of them, even the fans.
Most interesting for me personally is Razers Katana, the power supply unit. It is a modular power supply ranging from 750W to 1200W with the additional option of Titanium rated one with an impressive 1600W of power. Power supply will start shipping in early 2022 and at the time of writing this article no price range has been released.
Hanbo liquid cooler will feature an optimized intake design so it can ensure greater heat transfer and fluid dynamic for improved reliability and silent operation. Radiator comes in 240mm size with two fans and a larger one of 360mm with three fans. The pump will be able to rotate in any direction of full 360 degrees so it can fit in any case. Hanbo will be released in November this year but no pricing has been released so far.
Kunai fans will boast high static pressure performance with lowered noise. They will go as far as 2200rpm for the 120mm version where the 140mm version will go up to 1600rpm. They will come with addressable LEDs and up to eight fans will be able to be connected to Razer’s PWM fan controller that will come with a magnet at the back for easy attachment to any steel part of PC casing.
PWM will use Razer’s Synapse software to customize pulse width modulation in order to improve airflow and noise. PWM will be priced at $49.99 in the Razer Store and it is available for preorder. Fans are priced at $44.99 for one 120mm or $129.99 for a three-pack of 120mm. One 140mm will go for $49.99 and a three-pack will be $129.99.
