Dell Pro Slim QCS1250 — compact business desktop

The Dell Pro Slim QCS1250 is a small-form-factor desktop built around an Intel Core i9-12900K processor with 16 cores. It ships with 64 GB of DDR5 4800 memory and a 2 TB PCIe NVMe SSD. Windows 11 Pro is pre-installed and the chassis uses an 180 W internal power supply with air cooling.

Suited for office workloads and multi-monitor setups

This system fits users who need strong single-thread and multi-thread CPU performance for productivity apps, video calls and dual-display work via DisplayPort 1.4a and HDMI 2.1. Integrated Intel UHD Graphics 770 handles general business graphics. Buyers who require a discrete GPU for 3D rendering, CAD or gaming should look elsewhere, as the 180 W supply and slim chassis do not support add-in graphics cards.

64 GB DDR5 and 2 TB NVMe provide generous headroom

The memory capacity is fixed at the platform maximum of 64 GB, so no further RAM upgrades are possible. The single M.2 2280 slot is occupied by the 2 TB NVMe drive; a 3.5-inch SATA bay remains available for bulk storage expansion. The 180 W power supply limits total system power, so high-wattage components cannot be added.

Questions about this item

What monitor connections do I need to use the DisplayPort 1.4a and HDMI 2.1 outputs on this Dell Pro Slim QCS1250?

Connect one monitor to the DisplayPort 1.4a port and a second to the HDMI 2.1 port for dual-display support. Both ports are driven by the integrated Intel UHD Graphics 770 and support high-quality video output without extra adapters.

Can I keep using my existing USB 2.0 keyboard and mouse with the front and rear ports on this system?

Yes. The front panel includes two USB 2.0 Type-A ports and the rear panel provides two more USB 2.0 Type-A ports, so legacy USB 2.0 peripherals work directly without hubs or adapters.

How can I verify the 64 GB DDR5 4800 memory is running at the correct speed after setup?

Open Task Manager, select the Performance tab, click Memory and confirm the speed reads 4800 MHz. The system ships with two modules filling both slots for the maximum supported 64 GB capacity.
