Perfect for a tiny, fanless desktop PC, and you can use two in sync for double the power.
HDPLEX is known for its fanless PC cases, but the company just launched the world's smallest ATX power supply to complement them.
The HDPLEX 250W passive GaN AIO (All-In-One) ATX PSU(Opens in a new window) (via FanlessTech(Opens in a new window) ) uses what the company describes as "cutting-edge GaN (gallium nitride) technology" to achieve its small size. Measuring just 170-by-50-by-25mm, the slim profile PSU uses a full aluminum alloy body to help it quickly dissipate heat without need of a fan.
The use of a GaN chip allowed HDPLEX to break the 1W per cubic centimeter barrier, achieving 1.18W per cubic centimeter. As an added bonus it's also fully modular, which is highly desirable in compact PC builds where space is at a premium.
HDPLEX also made it possible to sync two of these PSUs within a PC using a cable included in the box. It means a silent 500W PC build is possible, or one PSU can be focused on providing power to a graphics card while the other handles power duties for the rest of the components.
Reducing the size of the power supply didn't come at the cost of efficiency. HDPLEX claims 94% efficiency at full load while satisfying the Level V Energy Efficiency standard(Opens in a new window) . The potential for vibration noise while operating has also been eliminated through the use of a unibody flat transformer.
The PSU is currently listed as out of stock, but HDPLEX says stock is expected for US customers at some point in June. The tiny power supply costs $145, but free shipping is offered worldwide. Included in the box alongside the PSU is that previously mentioned sync cable as well as five other standard cables for providing power to different components hooked up to your motherboard.

I've been working at PCMag since November 2016, covering all areas of technology and video game news. Before that I spent nearly 15 years working at Geek.com as a writer and editor. I also spent the first six years after leaving university as a professional game designer working with Disney, Games Workshop, 20th Century Fox, and Vivendi.
I hold two degrees: a Bachelor's degree in Computer Science and a Master's degree in Games Development. My first book, Make Your Own Pixel Art, is available from all good book shops.

All of my writing is done on a Windows 10 PC I built myself, which is hooked up to three 24-inch monitors. The software I rely on daily includes the Firefox web browser, Notepad++, VMware Workstation, Microsoft Excel, OneDrive, and a VPN for ensuring access to US websites because I'm based in the UK.
