3RSYS (3rsys.com) is the official website of Three R System Co., Ltd., a South Korean computer hardware manufacturer. The brand focuses on cooling and chassis products for the DIY PC market and is a well-known local Korean PC accessory brand. The site serves as a product showcase, after-sales portal, and customer inquiry channel.
The site's core features fall into three parts. First, a full product showcase covering CPU air coolers, all-in-one CPU liquid coolers, PC cases, case fans, custom liquid cooling components, and PC peripheral cables. Product specs are detailed and compatible with the latest mainstream platforms such as LGA1851 and AM5. Second, after-sales support with clear warranty policies and FAQ troubleshooting; users can request A/S service via three channels: online message, phone, or in-person drop-off. Third, an official store entry that directs users to purchase branded products.
As for pricing, the site does not publish unified product prices—users need to check Korean local sales channels, where products are priced individually by model.
On the plus side, 3RSYS offers a clear and user-friendly after-sales policy. Its AIO liquid coolers come with explicit hardware compensation for leaks, and mainstream products carry 3–6 year warranties—far longer than the industry average. The product line covers a wide range of build needs, from entry-level ITX cases to high-end workstation cases and high-TDP CPU coolers.
On the downside, the brand only serves the South Korean domestic market. The website is Korean-only, there are no official sales channels in mainland China, and warranty claims can only be filed in Korea, creating a high barrier for Chinese users.
The site suits DIY PC builders based in Korea who want to shop for PC components, as well as overseas shoppers looking to check product specs.
The site is currently accessible without a proxy, but the Korean-only interface poses a significant usability barrier for users in mainland China.
