ASUS ExpertCenter PN54-S1 Black 2026

A pint-sized port powerhouse for office work, but its graphics ability is basically a slideshow. Buy it for the connectivity, not the clock speeds.

Don't let the 'Ryzen 5' name fool you into thinking this is a desktop replacement powerhouse. In our testing, the Ryzen 5 220 lands in the 44th percentile for raw CPU grunt, which is solid but not staggering. What surprised us was how well it handles its designated lane. Multitasking across dozens of browser tabs, Office apps, and video calls is where this chip feels at home. It's efficient and stays cool, which means it's effectively silent even under load. However, for GPU-heavy tasks, the integrated Radeon 740M is a letdown, as expected, ranking in the bottom 15% for gaming. This box will not enjoy any title released in the last five years.

The Lenovo Legion Tower 5a is a direct competitor only if you squint. That machine is a gaming desktop in a mid-tower case with a discrete GPU, making it laughably more powerful for gaming but completely useless if you need a tiny, mountable office PC. The HP OMEN GT16-0364 is a similar story. If you actually need a mini PC, Apple's Mac Studio M4 Max is the elephant in the room. It crushes the PN54-S1 in CPU and GPU performance, but costs several times more and locks you into macOS. The ASUS isn't trying to win a benchmark war. It's here to be a Windows-based, impossibly small office PC with no distracting RGB or noise, a niche the gaming towers simply don't serve.

Pricing on this thing is all over the map, with vendors listing it anywhere from $815 to a completely absurd $23,860. Clearly, some listings are placeholder prices or bundled with expensive enterprise services. The real sweet spot, based on our data, lands around that $800 mark from retailers like Newegg. At that price, you're getting a connectivity monster with a current-gen processor and Windows 11 Pro. If you see it for over $1,000, close the tab. That's a markup on a convenience fee you don't need to pay.

The ASUS ExpertCenter PN54-S1 is a tiny desktop that knows exactly what it is, and that's refreshing. This isn't a machine for gamers or creative pros pushing 8K timelines. It's a workhorse built for spreadsheets, Zoom calls, and driving a command center of monitors. With an AMD Ryzen 5 220 and a port selection that's among the absolute best in our database, its mission is clear: be a reliable, quiet, and versatile hub for getting actual work done. The fact it can handle up to four 4K displays while sipping power is a real trick for something smaller than a hardcover book.

We dig the tool-free chassis, a design choice that screams 'IT department favorite.' Popping it open to swap RAM or storage takes seconds, not screwdrivers. And while the integrated Radeon 740M graphics won't set any records, that's not the point. ASUS shoved in Wi-Fi 7 and dual 2.5G Ethernet, making this a networking beast that feels ready for the next five years of office life. For the right person, this little box is a silent overachiever that disappears behind a monitor and just works.

Skip this one without a second thought if you're looking for even casual gaming. The integrated graphics here scored a 12.6 for gaming in our tests, which means it's effectively a non-starter for anything beyond Solitaire. If you want a small PC that can still play games, look at something with a discrete mobile GPU like a Zotac Magnus or an Intel NUC with Arc graphics instead.

Buy the ASUS ExpertCenter PN54-S1 if your priority is a dead-silent, tiny Windows box that can connect to everything you own. It's an exceptional digital signage player, a brilliant thin client, or the heart of a super-clean desk setup where performance demands are modest. This machine makes a strong case for being the most practical computer in the room. Just make sure you're comfortable with its ceiling. The moment you mention gaming or video editing, this conversation needs to end and you need to look at a desktop with a real GPU.
