This article covers Corsair MM800 RGB POLARIS ゲーミングマウスパッド MS285 CH-9440020-NA.

Overview

The Corsair MM800 RGB POLARIS is a long-running gaming mouse pad that pairs a low-friction glide surface with integrated RGB lighting. It is sold under the model number CH-9440020-NA, with the Japanese retail designation MS285, and its 350 x 260 x 5 mm footprint leaves comfortable room next to a full-size keyboard while still offering a generous aiming area. The micro-textured surface is designed to keep friction low for both optical and laser sensors, and the built-in USB passthrough adds practical cable management. For anyone who wants desk lighting without replacing their existing mouse, this pad is a simple upgrade that changes both feel and atmosphere.

Connectivity & Compatibility

The MM800 connects through a single integrated USB cable, so there is no external power adapter or separate hub required. That cable powers the RGB LEDs and provides one USB passthrough port, letting you plug a wired mouse or a wireless receiver close to your hand. Since the passthrough is a single port, users with several peripherals will still want a separate USB hub. The surface works with both optical and laser mice, and you can start using the pad immediately without installing drivers. For RGB customization, Corsair's iCUE software unlocks the full lighting profiles, although the pad still shows lighting in its default state without the software. It works equally well with desktop PCs and laptops that have a free USB port.

Product Info

The Corsair MM800 RGB POLARIS sits at the entry-to-mid tier of illuminated gaming mouse pads. It carries a two-year warranty, and the Japanese market unit (MS285) has generally been priced in the 7,000-8,000 yen range at major retailers. As a long-selling item, availability fluctuates and pricing can vary, but the integrated USB cable means no additional accessories are required to get started. Compared with newer RGB pads, its lighting is relatively straightforward, yet the combination of micro-texture glide, non-slip rubber base, and USB passthrough remains practical today.

Best Use Cases

For gamers who want desk lighting to match a Corsair setup, the MM800 makes sense because iCUE can sync effects across compatible devices. For those who prefer wired mice, the USB passthrough keeps the cable tidy and reduces drag by keeping the connection point near the mouse. Players who use low sensitivity and large arm movements will appreciate the 350 mm width, because there is enough surface for sweeping flicks. On the other hand, someone who only has limited desk space, or who prefers the soft feel of cloth pads, should look elsewhere — the micro-textured hard top has a distinct feel that is best tried before committing.
