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.The I100 Mesh is an interesting SFF case by PCCooler, with a handle on top that gives it the appearance of a boom box. Inside, there's room for a Mini-ITX motherboard, and three vertical slots, with a PCI-Express Gen 4 x16 riser connecting your graphics card. An AC receptacle takes power to a forward-mounted SFX PSU bay. You get room for graphics cards up to 30 cm in length, and 60 mm clearance for a CPU cooler, which should be enough for an AIO block that has its 240 mm radiator mounted along the top panel.The C3 T500 ARGB is a cube-shaped Micro-ATX tower with a pillarless front-left corner, tempered glass on two sides, a recessed side-facing 240 mm radiator mount, and a wide crawl-space behind the motherboard tray which makes the case backside connectivity friendly.Among the CPU coolers shown were the DS360 AIO liquid CPU cooler with an on-block coolant temperature display; and the DR360, with a slender, puck-shaped block. The R200 and RZ500 are the company's entry-level air CPU coolers.
