Dell OptiPlex 990 Mini Tower for home office

The Dell OptiPlex 990 Mini Tower is a desktop computer built for student and home office use. It runs on an Intel 2nd Gen i7-2600 processor with 64-bit architecture. The system includes 16 GB of DDR3 memory and a 3.5-inch 1 TB SATA hard drive. Windows 10 Pro 64-bit comes pre-installed with a USB keyboard and mouse included.

265 W power supply with integrated graphics

A 265 W power supply unit delivers power to the components. The Intel HD Graphics 2000 integrated graphics controller handles video output without a discrete card. Integrated audio and Gigabit Ethernet are built onto the motherboard. This combination keeps heat output and acoustic noise low during typical office workloads.

Quad-core 3.40 GHz CPU with 3.80 GHz Turbo Boost

The i7-2600 quad-core processor operates at a base frequency of 3.40 GHz and can reach 3.80 GHz with Turbo Boost across eight threads. Sustained multi-tasking performance is supported by the 16 GB DDR3 configuration. The 1 TB hard drive provides ample capacity for applications and data files over long sessions.

Spurningar um þessa vöru

How do I install additional DDR3 memory in the 240-pin DIMM slots and which step is often missed?

Power off, unplug the cord, open the Mini Tower case, align the notch on each DDR3 module with the 240-pin slot key, press firmly until the retention clips click, then close the case before powering on.

Which components in this OptiPlex 990 Mini Tower are most likely to need replacement after several years of use?

The 3.5-inch 1 TB SATA hard drive and the 265 W power supply are the parts that typically wear out first and may require replacement.

What is the first performance limit reached when the Intel Core i7-2600 runs at 3.80 GHz Turbo Boost for extended periods?

The 265 W power supply and the Mini Tower thermal envelope limit sustained Turbo Boost operation before the processor can maintain 3.80 GHz continuously.
