Aperçu

The 30-Second Version

The HP 400 G9 is a compact business mini PC with a 12-core i7, 32GB RAM, and a 1TB SSD. It's great for office work and multitasking, but the integrated graphics and limited ports hold it back. Worth buying if you need a small, quiet machine for daily productivity.

Pros & Cons

Points forts

  • Compact chassis fits almost anywhere, even behind a monitor with a VESA mount 70th
  • 32GB of RAM is generous for a business mini PC
  • Runs cool and quiet thanks to the 35W T-series chip
  • Wi-Fi 6 and Bluetooth 5.2 built in

Points faibles

  • Integrated graphics can't handle gaming or GPU-heavy workloads
  • Port selection is limited compared to other mini PCs
  • DDR4 RAM instead of newer DDR5
  • Marketing copy is inconsistent about which CPU is actually inside

Les preuves

Performance

The i7-12700T is a 35W chip with 12 cores and 20 threads, which is plenty for office work, light photo editing, and running a bunch of apps at once. Our database puts the CPU right around the middle of the pack for mini PCs, which sounds underwhelming until you remember this is a low-power part designed to stay cool and quiet. The 32GB of DDR4 RAM is a nice touch, it's above average for this category and means you can keep a ridiculous number of Chrome tabs open without sweating. Storage is a 1TB PCIe SSD, which is solid and fast enough for boot times and file transfers. The weak spot is the integrated UHD 770 graphics, it's fine for driving up to three displays and handling video playback, but don't expect to do any real gaming or GPU-heavy work. Port selection is also a bit thin for a business machine, it lands in the bottom fifth of our database, so you might need a hub if you have lots of peripherals.

vs Competition

Stacked against the competition, the HP 400 G9 holds its own for pure office work. The Lenovo ThinkStation P2 Tower Gen 2 is a much bigger machine with more expansion room, but it's a tower, not a mini, so it's not really a fair fight for desk space. The ASUS ROG NUC is smaller and more powerful for gaming, but it's aimed at a completely different buyer and likely costs more. The Skytech Legacy and CLX SET are gaming desktops with discrete GPUs, they'll crush the HP in graphics but take up way more space and draw more power. For a compact business machine, the HP's main trade-off is port selection and graphics, you're choosing small and quiet over expandable and powerful.

Value & Pricing

Pricing is a bit murky here. We only see one listing at 34,590 MXN, which is roughly mid-range for a business mini PC in that market. For that money you're getting a capable office machine with plenty of RAM and storage, but you're not getting a discrete GPU or cutting-edge memory. If your needs are email, documents, and video meetings, the value is reasonable. If you want any kind of graphics performance, you'll need to spend more elsewhere.

En savoir plus

Overview

The HP 400 G9 is a mini desktop aimed squarely at business users who need a small, quiet machine for daily remote work. It packs a 12-core Intel i7-12700T, 32GB of DDR4 RAM, and a 1TB SSD into a chassis that's barely bigger than a hardcover book. The spec sheet is solid for office tasks, though the marketing copy is a bit confused, it mentions a 14th gen i5 in one spot and a 12th gen i7 in another. The actual listing title says i7-12700T, so that's what we're going with.

This thing is built for spreadsheets, video calls, and multitasking across a few browser tabs. It's not a gaming rig, and the integrated Intel UHD 770 graphics make that clear. But for the right buyer, it's a tidy little workhorse that won't take over your desk.

Common Questions

Q: Can this run games?

Not really. The integrated Intel UHD 770 graphics are fine for video playback and basic display output, but gaming performance is one of the weakest areas for this machine. Stick to office work and light media.

Q: How many monitors can I connect?

You can connect up to three displays using the two DisplayPort 1.4 ports and one HDMI 2.1 port on the rear. That's plenty for most office setups.

Q: Is the RAM upgradeable?

The 32GB of DDR4 RAM is already above average for this category, so most users won't need to upgrade. If you do want to, you'd need to check the internal layout, but mini PCs like this often have limited upgrade options compared to towers.

Who Should Skip This

Skip this if you need any kind of graphics horsepower. The integrated UHD 770 can't handle gaming, video editing with effects, or 3D work. Also skip it if you rely on lots of USB devices, the port selection is thin and you'll be buying a hub on day one. And if you want the latest memory tech, this uses DDR4, not DDR5.

Verdict

The HP 400 G9 is a sensible pick for remote workers, office staff, and anyone who wants a tidy desktop that handles everyday tasks without fuss. It's quiet, compact, and has enough RAM and storage to stay useful for years. Just don't expect it to do anything graphically demanding, and budget for a USB hub if you have a lot of accessories.
