PCCooler may seem like a new brand, but is at least 13 years old in the market now, with its claim to fame being the air+liquid CPU cooler from 2011. The company brought plenty of gear to its 2024 Computex booth. There are at least four PSU series, mostly covering mainstream, mid-range, and the performance segments of the market. The KF series is at the entry-level, and features fixed cabling, along with 80 Plus (baseline) efficiency. This sticks to the older ATX 2.53 standard. The YK series is the company's most affordable PSU series to meet ATX 3.1 and PCIe Gen 5.1 specs. You get fixed cabling here, too, including a fixed 12V-2x6 on some of the higher wattage models (750 W and above); but with 80 Plus Bronze efficiency. The YN series is a notch above, with capacities of up to 1000 W, ATX 3.1 + PCIe Gen 5.1, Cybenetics Gold switching efficiency, and Cybenetics A- acoustics. The YS series is on the top, with wattages going up to 1200 W. Both the YN and YS include a 600 W-rated 12V-2x6 connector.

What happens when you mash up a CPU tower-type air-cooler with a water-block? You get PCCooler OC3 W120. This innovative cooler combines a tower-type air cooler design with a water block. First, there's a typical heatsink that has a polished copper base and heat pipes originating from the base, conveying heat to a aluminum fin stack; next, at the top of the stack are fittings that connect the cooler to a liquid-cooling loop. The water tubes pass through the aluminum fin stack just like heat pipes, before reaching the base of the heatsink. At the base, a micro-fin plate and block chamber makes direct contact with the heat pipes and the base below.

The aluminum fin stack holds one 120 mm fan to ventilate it. The fins are of irregular shape and are dimpled to increase surface area and turbulence. With its unique hybrid design, the PCCooler OC3 W120 can handle thermal loads of up to 500W. PCCooler OC3 W120 is made by Chinese company Shenzhen Fluence Technology, its products are exclusively sold in the Asian markets.
