Dell OptiPlex 990 SFF for home office

This Dell OptiPlex 990 small form factor desktop is built for everyday computing tasks. It runs on an Intel quad-core i5 processor clocked between 2.9 and 3.30 GHz with a 3.40 GHz turbo boost. The system includes 16 GB of DDR3 memory and a 256 GB 2.5 inch SSD. Windows 10 Pro 64-bit comes pre-installed for immediate use.

Sustained load behaviour with integrated graphics

The Intel HD Graphics 2000 handles general desktop work and video playback without a discrete card. Under continuous multi-threaded loads the quad-core CPU maintains performance within its thermal envelope. The 256 GB SSD keeps read and write speeds consistent during extended file operations. Gigabit Ethernet and a USB WiFi adapter provide stable network connectivity for long sessions.

Installation notes for the SFF chassis

The small form factor case limits internal expansion to low-profile cards only. Memory uses 240-pin DDR3 DIMM slots so upgrades must match that standard. A DVD±RW drive is already fitted in the single external bay. USB keyboard and mouse are included in the box for quick setup. Monitor is not included and must be sourced separately.

Questions about this item

How much heat and noise does the Intel Quad-Core i5 2.9-3.30GHz produce under sustained load in the SFF case?

The small form factor chassis uses a compact heatsink and a single system fan; under continuous multi-core workloads the CPU will reach its thermal limits quickly, so expect audible fan spin and warm exhaust air from the rear vent.

Which peripherals and cables are not included and must be supplied separately for first boot?

A display with VGA or DisplayPort input, a compatible video cable, and a mains power lead are required; the box provides the desktop, USB keyboard, USB mouse and a WiFi USB adapter only.

Will the Intel HD Graphics 2000 and DDR3 memory work reliably with a legacy PCI add-in card I still use?

The motherboard offers one low-profile PCI slot alongside PCIe x16 and x1 slots; the integrated graphics and 16 GB DDR3 remain active, so a legacy PCI card can be installed without disabling onboard video or memory.
