The Eurocom 780W AC Power Adapter Review: Big Power For Big Laptops While desktop PC power supplies receive the bulk of enthusiasts’ attention for good reasons – not the least of which being the vast selection of options that comes from being a standardized part – power supplies as a whole aren’t just a concern for big PCs. With the majority of PC sales having flipped to notebook sales some years ago, notebook power supplies already lead the market in volume. And while most laptops don’t need the kind of massively powered PSUs that dominate the desktop space, even that is slowly changing as desktop replacement-class laptops increasingly grow in performance and power consumption. Perhaps the poster-child for the high-performance, high-powered laptop is Eurocom, who has a long history of developing heavy-duty DTR laptops that are all but portable desktop systems. Following recent trends in GPU power consumption and in GPU popularity for both gaming and AI workloads, the company has been selling a range of “mobile supercomputers”, which are practically large, tailor-made laptops that rival even the best of desktop computers – and have the power requirements to match. In order to power their own high-end laptops, Eurocom has developed a rather unusual 780W AC adapter for high-performance laptops. Intended to power the most powerful of powerful laptops, their latest power adapter can supply over three-quarters of a kilowatt of DC power; a desktop-like wattage for a desktop-like device. It’s a laptop power adapter that’s unique in its scale, and with some room to scale up even further.

But it’s taken on a new life as more laptops have been released that use such a large adapter (or two smaller 300W-ish power adapters). And, critically, Eurocom has made additional DC cable/connector sets for other manufactuers’ laptops, significantly increasing the number of systems it’s compatible with. Currently, Eurocom offers DC cables for the following laptops: Alienware M17x M18x; 1x DC Cable ; w/ barrel AW connector; 193cm/6.4ft Alienware AREA 51m; 1x DC Cable + Splitter Box w/ 2x barrel AW connectors; 152cm/5ft ASUS ROG G18 Strix; GX501V; GM501; GM501GM; GX531GM; 1x DC Cable; w/ barrel ROG connector ASUS G703GX, GZ700GX; 1x DC Cable w/ 2x ROG barrel connectors; 152cm/5ft CLEVO, OriginPC, Sager, XMG, EUROCOM laptops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft CLEVO X370SNx; 1x DC Cable; w/ square connector; 120cm / 3.8ft CLEVO X170SM/X170KM; 1x DC Cable; w/ dual square connectors; 152cm / 5ft Dell Precision 7720/7710; 1x DC Cable; w/ barrel Dell connector; 120cm / 3.8ft MSI GE76, GT76, GT77, GE78HX Raider, Titan 18HX 1x DC Cable; w/ single square connector; 120cm / 3.8ft MSI laptops & MSI Trident AS Gaming Desktops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft
