Dell OptiPlex 5090 | Intel Core i5 11th Gen | 8GB RAM | 500GB HDD | Small Form Factor
A compact business machine that frees up desk room and stays ready for quicker upgrades later.
Condition: Used
Note: price and availability are subject to change without prior notice
The Dell OptiPlex 5090 is in stock at Mascom International, priced at KSh 46,000, with an Intel Core i5 11th Gen processor, 8GB RAM and a 500GB hard drive. This used Dell OptiPlex 5090 comes in Dell's small form factor case, about 93mm wide, so it stands on a desk or lies under a monitor. It arrives as a lightly used international import with a tested power cable. Come and inspect it at the Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, where our staff will boot it up and walk you through the ports.
Designed for receptionists, lawyers, estate agents and bank-hall clerks, the Dell OptiPlex 5090 handles case files, client records, email and browser-based systems in offices where floor space is tight. A chambers in Upper Hill or a small agency in Kilimani rarely has room for a full tower under every desk. The Dell OptiPlex 5090 solves that with a slim case that still holds six processor cores, ten USB ports and two DisplayPort outputs. It also has an M.2 slot, so a solid-state drive can be added later for much quicker start-up.
Unlike other electronics retailers in Kenya that sell grey-market desktops with no paper trail, Mascom International tests each Dell OptiPlex 5090 and backs it with a six-month warranty from a physical shop. At Mascom International, we're seeing law firms and clinics replace older 6th Gen machines with the Dell OptiPlex 5090 for its newer chip. Buyers throughout Kenya report that the slim case is easy to carry between branches. Confirm on WhatsApp which accessories and operating system come with your Dell OptiPlex 5090, then order with pay-on-arrival delivery or collect it from Kimathi Street.
Common Questions About the Dell OptiPlex 5090
What is the Dell OptiPlex 5090 i5 11th Gen price in Kenya?
The used Dell OptiPlex 5090 with an Intel Core i5 11th Gen, 8GB RAM and 500GB HDD sells for KSh 46,000 at Mascom International, Nairobi CBD. You get the system unit, a tested power cable and six months of hardware cover. Payment happens on arrival, by cash or M-Pesa, once the courier hands the desktop over. Buyers who prefer a bigger case with more expansion slots can save KSh 6,000 with the Dell OptiPlex 7080 i5 10th Gen at KSh 40,000.
Is this Dell OptiPlex 5090 used or refurbished, and what is the difference?
The Dell OptiPlex 5090 we sell is used: a lightly used international import that came from an overseas office and was never deployed locally in Kenya. A refurbished machine goes through a formal restoration by the maker or a certified workshop, often with new parts fitted. Our used units are cleaned and tested, but the case may carry small marks from earlier service. Ports and fitted extras such as Wi-Fi or a card reader differ between units, so check the exact machine with us on WhatsApp.
Dell OptiPlex 5090 or Dell OptiPlex 7080: which suits a small office better?
The Dell OptiPlex 5090 suits a small office better when desk and floor space are limited, because its case is far slimmer than the Dell OptiPlex 7080 tower. It also carries a newer 11th Gen processor and an M.2 slot for a fast drive. The Dell OptiPlex 7080 costs KSh 6,000 less and has four expansion slots plus serial and PS/2 ports. Go with the Dell OptiPlex 5090 for a tidy, modern desk; go with the Dell OptiPlex 7080 for legacy devices.
Does the Dell OptiPlex 5090 have Wi-Fi for Safaricom or Airtel home internet?
Wi-Fi on the Dell OptiPlex 5090 depends on the unit, because Dell sold it with wireless as an option rather than as standard. Every unit has a Gigabit Ethernet port, which connects straight to a Safaricom Home Fibre, Airtel or Zuku router with a cable. Units without wireless still have an M.2 slot inside where a Wi-Fi and Bluetooth card can be fitted. A wired connection is often steadier in busy CBD buildings, where many neighbouring routers crowd the airwaves and slow wireless links down.
Who should buy the Dell OptiPlex 5090, and who should skip it?
The Dell OptiPlex 5090 is right for professionals who want a modern, quiet desktop for documents, eCitizen and KRA portals, case management software and video meetings. It fits receptions, clinics, schools and branch offices where space is short. Skip it if you plan to game, edit video or run CAD design software, because integrated graphics and a hard drive will slow that work. For those jobs, the Lenovo ThinkStation P340 with an i7 10th Gen, 16GB RAM and SSD at KSh 54,000 is the better fit.
Can the Dell OptiPlex 5090 run Windows 11?
Yes, the Dell OptiPlex 5090 meets Microsoft's processor requirement for Windows 11, since 11th Gen Intel chips are on the supported list. That gives the machine a longer software life than older 6th and 7th Gen office desktops, which Microsoft does not support for Windows 11. Mascom International does not sell this unit with a Windows licence included. Ask on WhatsApp which operating system is installed on your unit before buying, and we can advise on licensing from there.
Can I add an SSD to the Dell OptiPlex 5090?
Yes, the Dell OptiPlex 5090 has an M.2 slot that accepts 2230 or 2280 size NVMe solid-state drives, alongside the existing 500GB hard drive. An NVMe SSD reads data far faster than a spinning disk, so start-up and program loading become noticeably quicker. You can install the operating system on the SSD and keep the hard drive for documents and backups. Mascom International stocks SSDs and can fit one at our Kimathi Street shop if you ask when ordering.
How much desk space does the Dell OptiPlex 5090 need?
The Dell OptiPlex 5090 small form factor case measures about 290mm deep, 93mm wide and 293mm tall, roughly the size of a large hardcover book. It weighs from about 4.4kg, light enough to carry between branch offices in Nakuru or Mombasa. It can stand upright beside a monitor or lie flat beneath one. Leave a little space around the vents so warm air can escape, especially in hot ground-floor shops without air conditioning.
Technical Specifications
Processor
- Intel Core i5 11th Gen desktop processor — a six-core chip that keeps several business programs running smoothly together.
- Twelve threads — two task streams per core, which helps when a browser, Outlook and a database run side by side.
- Newer than the 10th Gen chips in many office desktops — and on Microsoft's supported list for Windows 11.
- Runs on mains power with no battery limits — performance stays consistent through long days at a reception or till.
- Good for office suites, legal and medical records software, and video calls — not meant for heavy 3D or gaming.
Memory
- 8GB RAM — comfortable for one user with email, a browser, a document editor and a video call open at once.
- DDR4 desktop memory — the common standard for this generation, so extra modules are straightforward to buy in Nairobi.
- RAM is the space programs use while open — more of it means fewer slowdowns when you switch tasks.
- Upgrading to 16GB helps people who keep many browser tabs or large spreadsheets open all day.
- Ask on WhatsApp about adding memory before delivery — our technicians can fit it at the Kimathi Street shop.
Storage
- 500GB HDD — a spinning hard disk that gives ample room for files at a lower cost than an SSD.
- Room for roughly 60 hours of Full HD video, or well over a hundred thousand smartphone photos, before it fills.
- One M.2 slot for a 2230 or 2280 NVMe SSD — NVMe drives load programs far faster than a hard disk.
- Three SATA connections inside — space for extra 3.5-inch or 2.5-inch drives, or a slim optical drive.
- Optional SD 4.0 card reader and DVD writer on some units — check with us on WhatsApp if you need either.
Graphics
- Intel UHD integrated graphics — built into the processor, so there is no separate video card drawing extra power.
- Two DisplayPort 1.4 outputs on the rear — run two monitors side by side for spreadsheets and case files.
- Older monitors with HDMI or VGA inputs need a DisplayPort adapter cable, which Mascom International can supply.
- One half-height PCIe x16 slot — a slim graphics card can be added later if your work needs it.
- Plays Full HD video, presentations and online meetings smoothly — not built for current games or 4K editing.
Connectivity
- Front ports: one USB 3.2 Gen 1, one USB 3.2 Gen 2 Type-C, two USB 2.0 and a universal audio jack.
- One front USB 2.0 port supports PowerShare — it can charge a phone while the desktop is switched off.
- Rear ports: four USB 3.2 Gen 1, two USB 2.0 and a line-out audio port that can also take line-in.
- RJ-45 Gigabit Ethernet — a wired network port for office LANs and home fibre routers, steadier than Wi-Fi.
- Wi-Fi and Bluetooth vary by unit — an internal M.2 2230 slot accepts a wireless card where none is fitted.
Build and Form Factor
- Small form factor case — about 290mm deep, 93mm wide and 293mm tall, so it fits on crowded desks.
- Weight starts from about 4.4kg — easy to move between offices or carry to a branch in another town.
- Power supply rated at 200W or 300W depending on configuration — confirm the one in your unit on WhatsApp.
- Second half-height PCIe x4 slot — space for a network card, extra USB card or similar add-on.
- Clean used condition — small marks from previous office use may appear, so ask for photos of your unit.
