Pro Micro 1255 for Business Users

The Dell Pro Micro 1255 is a micro form factor desktop built for business professionals who need reliable performance in a compact chassis. It ships with Windows 11 Pro and includes a Dell keyboard and mouse for immediate deployment. The AMD Ryzen 7 Pro 8700GE 8-core processor handles office productivity and multitasking workloads efficiently. This system suits users who value space savings without sacrificing core computing power.

Sustained Load Behaviour with 90W Power

The 90W power supply defines the thermal envelope for the AMD Ryzen 7 Pro 8700GE during extended work sessions. With a base clock of 3.60GHz and a boost up to 5.10GHz, the processor manages frequencies within this fixed power budget. The 16MB L3 cache and 32GB DDR5 memory help maintain throughput on data-heavy tasks without relying on the 256GB SSD for swap. Builders who need higher sustained graphics or compute performance should look elsewhere.

Connectivity Limits of the Micro Chassis

Wired networking is restricted to Gigabit Ethernet, capping LAN transfers at that standard. Wireless connectivity uses Wifi-7 for modern client support. Video output relies on DisplayPort and HDMI for multi-display setups. Peripheral expansion offers 3 x USB 3.2, 2 x USB 2.0, and 1 x USB Type-C 3.2 ports. Buyers who require additional internal drive bays, discrete graphics slots, or faster wired networking cannot add them to this form factor.

Questions about this item

How much heat and noise does the 90W power supply generate during all-day operation?

The 90W supply is sized for the 8-core AMD Ryzen 7 Pro 8700GE and integrated Radeon graphics, so sustained loads stay within its thermal envelope without extra fan noise.

Which display cables must I already own to use the multi-display outputs?

You need your own DisplayPort and HDMI cables; the micro chassis provides both ports but no cables are included in the box.

Will my existing USB 2.0 peripherals work with the front and rear ports?

Yes, the system includes two USB 2.0 ports alongside three USB 3.2 and one USB Type-C 3.2, so legacy keyboards, mice or printers connect directly.
