Compact desktop for basic tasks

The Dell OptiPlex 755 is a small form factor desktop aimed at students and home offices needing a simple machine for web browsing, email and document editing. Its 1.8 GHz Intel Celeron processor and 2 GB of DDR2 memory handle light workloads within the limits of the Intel Q35 chipset. The system arrives with a licensed copy of Windows 7 Home Premium pre-installed.

DDR2 memory and storage limits

The platform supports only DDR2 memory with a single installed module and a maximum of one module total, so capacity cannot be expanded beyond the fitted 2 GB. The 80 GB hard drive provides modest space for documents and media, while the integrated Intel GMA 3100 graphics rely on system memory and the 800 MHz front-side bus.

280 W power supply constraint

A 280 W power supply restricts the components that can be added, ruling out dedicated graphics cards or high-wattage upgrades. Buyers who need more storage, faster memory or a discrete GPU should consider a larger chassis with a higher-capacity PSU.

Questions about this item

Should I choose the 80 GB hard drive or look for a larger capacity?

The 80 GB hard drive is the only storage option listed for this OptiPlex 755 SFF.

What does the 1.80 GHz Celeron processor mean for everyday performance?

The 1.80 GHz Intel Celeron with 800 MHz FSB handles basic home office tasks and web browsing within the limits of the installed 2 GB DDR2 memory.

Does the DDR2 memory type limit what I can upgrade to later?

Yes, this system uses DDR2 memory only; other DDR generations are physically incompatible and will not fit the motherboard slots.
