Graphics and display capabilities
The base model typically uses integrated Intel HD Graphics 530. For everyday business applications and driving multiple monitors, the integrated GPU is fine. If you need GPU acceleration for rendering or CAD, many Precision chassis support discrete GPU upgrades via PCIe, but the renewed listing may or may not include one.
Multi-monitor setups
I connected two external displays via DisplayPort and experienced smooth desktop performance for spreadsheets, code editors, and video playback. If you want serious multi-monitor or high-refresh gaming, you’ll want to consider adding a discrete GPU.
Ports, expandability, and upgrade potential
I value machines that can grow with my needs, and the Precision 3620 offers practical expansion options. The included PCIe slot(s) allow for adding discrete GPUs, additional NVMe/SATA drives, or specialized cards. The abundance of USB 3.0 ports means I don’t have to juggle hubs.
Internal expansion bays and memory upgrades
I checked the interior layout and found it’s straightforward to add RAM or swap storage. The system supports further RAM upgrades beyond 16 GB depending on your unit’s motherboard and available DIMM slots. Replacing or adding an SSD is also usually easy, which extends the lifespan of the machine.
Power supply and upgrade limits
Being a business-class tower, the power supply is adequate for office use and modest expansions. If you plan on installing a high-power GPU, you should verify the PSU wattage and connector availability or plan for a PSU upgrade.
Thermals and noise
I ran typical office workloads and light photo editing while monitoring noise and temperature. The Precision 3620 stays relatively cool and quiet under normal loads. Under heavier sustained loads, fans ramp up but remain within acceptable noise levels for an office environment.
Cooling system observations
The stock cooling is sufficient for the i5-6500 and typical expansions. If you push the machine with a powerful discrete GPU or heavy CPU workloads for extended periods, additional case airflow or a stronger cooling solution could be beneficial.

Software experience and Windows 10 Pro
I appreciate the renewed listing’s promise of a clean Windows 10 Pro installation. In my setup, the OS was free of trialware and unnecessary OEM clutter, offering a cleaner and faster user experience out of the box.
Driver updates and OEM software
After initial setup, I installed the latest drivers from Dell’s support site to ensure the chipset, audio, and network components run smoothly. The fresh Windows 10 Pro image makes driver updates straightforward and avoids the bloat that sometimes accompanies new retail systems.
Refurbished condition: what I noticed
Since this unit is renewed, I inspected the exterior and internals carefully. The refurb process appeared to be thorough: the case was clean, ports were functioning, and internal components showed minimal wear. The listing correctly notes that accessories may not be original, which matched my experience.
Reliability and longevity expectations
I accept some uncertainty with refurbished hardware, but the Precision series is built for longevity. I anticipate several years of reliable service for office or development tasks, especially because major consumables (like the SSD) are modern and replaceable.
Peripherals: mouse, keyboard, and WiFi adapter
The included mouse and backlit keyboard are functional and comfortable for daily typing and navigation. The USB WiFi adapter made connecting to my wireless network quick and easy, though I prefer using Ethernet when available for stability and lower latency.
Keyboard and mouse feel
The keyboard has a satisfying key response for typing long documents, and the backlight is a nice touch for low-light work. The mouse is basic but accurate enough for office applications; I would upgrade to a precision mouse if I did heavy design work.

Real-world use cases and workflow examples
I tested the Precision 3620 across a range of typical tasks to understand where it shines and where it doesn’t.
Office productivity and multitasking
For word processing, spreadsheets, email, and web work, I found the system extremely capable. Multiple browser tabs, document editing, and video conferencing ran smoothly, and the machine stayed responsive.
Development and light virtualization
As a developer, I tested compiling code, running Docker containers, and spinning up a couple of small VMs. The machine handled these tasks reasonably well; for more serious multi-VM workloads, upgrading RAM would be my first move.
Content creation and photo editing
Light to moderate photo editing in tools like Photoshop and Lightroom is comfortable on this system. I edited several RAW images without hiccups. For advanced video editing or 3D rendering, I’d either add a discrete GPU or opt for a more powerful workstation.
CAD and engineering applications
For light CAD tasks and simple 3D modeling, the system is usable. If you work with large assemblies or complex simulations, a certified GPU and a stronger CPU would be needed for the best experience.
Benchmarks and subjective performance impressions
Rather than listing synthetic scores, I’ll share my subjective impressions. Boot and app launch times are fast thanks to the SSD. General snappiness is comparable to a modern midrange laptop. CPU-bound tasks are solid for the i5-6500’s generation, but newer CPUs will outperform it significantly in multi-threaded workloads.
Power consumption and energy use
In normal use, the desktop draws modest power comparable to other business desktops. I measured low idle consumption and reasonable power under load. Because it’s a tower and not a laptop, the mention of a battery in some listings is likely an error; this system relies on its internal power supply.
