Overview

The renewed Dell OptiPlex 390 is a second-generation Intel Core i5 desktop — a commercial-grade machine originally built for enterprise office deployments, now refurbished and packaged with a 22-inch monitor as a complete workstation bundle. The Core i5 at up to 3.4 GHz, 8GB DDR3, and 1TB HDD combination is a known configuration from this platform generation: capable of running Windows 10, Microsoft Office, and standard browser-based productivity tools without becoming a bottleneck on CPU throughput. What the spec sheet can't hide is the HDD — spinning mechanical storage at this generation is the defining performance ceiling, and it is felt on every boot and application launch.

The OptiPlex 390 chassis was built to commercial durability standards, which means it handles daily use reliably and the internals are accessible for straightforward upgrades. The jump to a SATA SSD is a low-cost, high-impact modification that any technically comfortable user can perform in under 30 minutes; the RAM can be taken to 16GB equally easily. For anyone setting up a light-duty workstation for basic productivity, point-of-sale, or an air-gapped internal-use environment, the all-in bundle value is genuine — keyboard, mouse, and monitor included at a total cost well below any new system with comparable connectivity. Just factor in a SATA SSD to the budget and you have a machine that punches well above its purchase price.

Pros & Cons

👍 Pros

  • Complete workstation bundle — 22-inch monitor, keyboard, and mouse included means zero additional purchases to be operational out of the box.
  • Core i5 up to 3.4 GHz handles core productivity tasks — Office, email, web, video calls — without bottlenecking on CPU throughput.
  • 1TB HDD provides ample local storage for documents, downloads, and media libraries without additional drives.
  • Both VGA and HDMI outputs allow connection to a wide range of monitors and enable dual-display configurations on a budget.
  • Renewed certification means the unit has been inspected and tested to functional standards, reducing the risk of receiving a broken machine.

👎 Cons

  • 1TB spinning HDD is the dominant performance bottleneck — boot times and application launches are significantly slower than any SSD-equipped system at this price point.
  • DDR3 memory architecture is a hard ceiling; no upgrade path to faster DDR4 speeds regardless of RAM capacity installed.
  • Second-generation Core i5 has no hardware support for modern security features like PTT/TPM 2.0, which may block a clean Windows 11 upgrade path.
  • Monitor brand and condition varies between units — screen quality and cosmetic state are not guaranteed to a specific standard.
  • Windows 10 is past end-of-support, meaning no further Microsoft security patches for internet-connected deployments.

Frequently Asked Questions

The Dell OptiPlex 390 uses a second-generation Intel Core i5 (Sandy Bridge), clocked up to 3.4 GHz. For everyday productivity — web browsing, Office applications, video calls, and light document work — the single-core performance is adequate. You will notice limitations running modern browser-heavy workflows with many tabs open simultaneously, or any workload that benefits from newer instruction sets (AVX2, AES-NI acceleration in some applications).
8GB DDR3 handles light to moderate multitasking in Windows 10 adequately. The OptiPlex 390 supports up to 16GB DDR3, so a RAM upgrade is feasible and inexpensive given DDR3 pricing. If your workload involves multiple browser sessions, Office alongside a video call, or any light virtual machine use, upgrading to 16GB would be the first recommended performance investment.
Yes — the spinning HDD is the most impactful bottleneck in this configuration. Boot times, application launch speed, and file transfer rates are all measurably slower than an SSD-equipped system. Replacing the HDD with a SATA SSD (a straightforward swap on this chassis) would transform the day-to-day feel of the machine more than any other single upgrade.
The OptiPlex 390 provides both VGA and HDMI outputs. The bundled 22-inch monitor connects via one of these — monitor brand varies by unit. If you already have a monitor with either connection type, the second output is available for dual-display use, provided the integrated Intel HD graphics can drive two outputs simultaneously (it can on most 390 configurations).
Windows 10 reached end of mainstream Microsoft support in October 2025. It remains functional, but will no longer receive security updates, which is a relevant consideration for any internet-connected machine. For isolated internal-network use or air-gapped environments it's a non-issue; for general internet use, a Windows 11 upgrade evaluation is worth performing (hardware compatibility varies on this platform).
