Preparation Underway for InWin's 1650W GPU Power Supply, Featuring Four 16-pin Power Cables
Introducing the InWin IW-1650W, an exclusive power supply specially crafted to fuel up your graphics cards like never before. This beast delivers a whopping 1,650W of unadulterated power, primarily for your GPU-packed rigs. Initially unveiled at Computex 2025, its unique single-rail design makes it ideal for cranking up your high-end graphics cards such as the GeForce RTX 5080, supporting a maximum of four of them.
This powerhouse features four 12V-2x6 power connectors, compliant with the PCIe 5.1 CEM standard, and a modular design that lets you chop off the excess cables like a well-timed guillotine drop. The IW-1650W also boasts up to 90% efficiency, boosting an active PFC of 0.99, and it keeps itself chilled utilizing a 13.5cm cooling fan.
However, it's essential to keep in mind that, just like a racehorse needing the right pasture, the efficiency of the IW-1650W can vary from system to system. Depending on your graphics card's requirements, one might not be able to deploy the full 1,650W potential – so, be prepared to feed your rig with enough power to make it roar!
With the advent of 3000W power supplies hitting the market in 2025, pairing the IW-1650W with a lower-capacity unit might seem folly. While doing so would be a mere workaround for that pricey 3000W option, you could still dive into the pool of insanity by coupling two IW-1650W units, but let's be honest – who in their right mind needs 4650W, huh?
Although InWin hasn't yet spilled the beans on pricing for the IW-1650W, you can anticipate it to sport a premium tag compared to run-of-the-mill power supplies, much like its 1600W+ counterparts from leading manufacturers (often going for around $600 or more). Given the limited availability of such specialized products, we'll just have to wait and see if the IW-1650W is exactly what makes your GPU-loaded dreams come true!
