HP ProDesk 400 G6 SFF | Intel Core i3 9th Generation | 8GB DDR4 RAM | 500GB HDD | Intel UHD Graphics 630
A compact business tower that keeps Nairobi offices, cyber cafes, and school computer labs running without stretching a tight budget.
Condition: New
Note: price and availability are subject to change without prior notice
HP ProDesk 400 G6 SFF with a 9th Generation Intel Core i3 processor, 8GB of DDR4 memory, and a 500GB hard drive is available now at Mascom International for KSh 27,000. This HP ProDesk 400 G6 SFF arrives as a carefully maintained international import, never deployed locally in Kenya, and every unit is bench-tested before it reaches the shelf. Find the HP ProDesk 400 G6 SFF at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, open Monday to Saturday from 9:00 AM to 7:00 PM. The chassis measures just 95mm across, so the HP ProDesk 400 G6 SFF sits beside a monitor on a standard office desk instead of swallowing the legroom underneath.
Accountants filing KRA returns, SACCO clerks posting member records, cyber cafe operators running eight machines at once, and school computer labs teaching Word and Excel all want the same thing from a desktop: it boots, it runs, and it keeps running for years. At KSh 27,000, the cost works out to KSh 750 a month across a three-year service life. The four-core i3 processor carries QuickBooks, Sage, Tally, and the iTax portal side by side without stalling. Small firms in Industrial Area and Westlands, and branch offices in Nakuru or Kisumu, get tested business hardware rather than a budget machine that struggles by month three.
Unlike traditional electronics retailers in Kenya that sell untested imports through a phone number and one blurry photo, Mascom International checks drive health, memory, ports, and the power supply on every HP ProDesk 400 G6 SFF before listing it. Buyers consistently report that the 180W 80 PLUS Gold supply pairs cleanly with a small 650VA UPS, which matters on lines that trip often. At Mascom International, we are witnessing steady demand from offices retiring ageing Core 2 Duo towers one desk at a time. Walk into Kimathi Street to boot the HP ProDesk 400 G6 SFF yourself, or order it for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the HP ProDesk 400 G6 SFF
What can this desktop handle in a normal working day?
Office workloads run comfortably: accounting packages, browser research, email, and printing, all at the same time. The four-core 9th Generation Intel Core i3 holds 3.6GHz across every core under sustained load, so Sage, Tally, and the KRA iTax portal stay responsive with fifteen browser tabs open beside them. What it does not suit is 4K video editing, 3D rendering, or current-generation gaming, which need a discrete graphics card and far more memory. For document work, data entry, and point-of-sale duty, it has room to spare.
Is this unit used or refurbished?
It is used, not refurbished, and the difference is worth knowing. A refurbished machine has had parts swapped by a certified workshop and is sold under that workshop's terms. This HP ProDesk 400 G6 SFF is a carefully maintained international import in clean used condition, never deployed locally in Kenya, with its original HP components intact. Mascom International tests drive health, memory, every port, and the power supply, then backs the unit with a 6-month warranty. You see the actual machine before any money changes hands.
Will the HP ProDesk 400 G6 SFF run Windows 11?
Yes. The board carries an Infineon TPM 2.0 chip and a UEFI BIOS with Secure Boot, which are Microsoft's two hard requirements. Intel 8th Generation processors and newer sit on Microsoft's supported CPU list, and the 9th Generation Core i3 in this tower qualifies. Most units arrive carrying Windows 10 Pro from their original deployment. Mascom International sells genuine Windows 11 Pro licences separately at the Kimathi Street counter if you would rather do a clean licensed installation than an in-place upgrade.
Can I fit an SSD later?
Yes, and it is the one upgrade that changes this machine most. A free M.2 2280 slot runs PCIe NVMe drives at read speeds up to 2,900MB/s, against roughly 120MB/s from the fitted 500GB hard drive. Boot times fall from about ninety seconds to under twenty. Three SATA ports also accept a 2.5-inch SATA SSD if you prefer that route. Keep the hard drive in place as bulk storage for scanned records. Mascom International stocks both drive types and fits them on request.
How much memory can this tower take?
Two DIMM slots accept up to 64GB of DDR4 in total, using 32GB modules. The 9th Generation Core i3 runs memory at 2400 MT/s, so paying for faster modules brings no gain on this chip. The practical step for most Kenyan offices is a second matched 8GB module, reaching 16GB and switching the board into dual-channel mode, which also lifts integrated graphics speed. Both slots sit within easy reach once the side panel slides off. Nothing is soldered down.
What comes with it at Mascom International?
The tower, a 240V power cord, and a warranty card. Used business imports do not arrive in original retail boxes, so expect no printed manual, no driver disc, and no branded packaging. Monitors, keyboards, mice, and Windows licences are priced separately, which is what keeps the tower itself at KSh 27,000 rather than bundled up. Ask about rollout pricing if you are kitting out a computer lab or an office with several units at once.
Why choose this over a Dell OptiPlex 3070 SFF?
Both are 2019 business towers built around 9th Generation Intel processors, and both are sensible buys. The HP ProDesk 400 G6 SFF runs a narrower 95mm chassis, an 80 PLUS Gold 180W supply, and a free M.2 NVMe slot alongside three SATA ports. Spare parts for HP business desktops circulate more widely in Nairobi's Luthuli Avenue trade than Dell equivalents, which shortens repair waits upcountry. Unlike other electronics retailers in Kenya, Mascom International tests and warranties the unit instead of selling it as seen.
Does it work with a small UPS during power cuts?
Yes. The 180W 80 PLUS Gold supply draws around 10 watts at idle and rarely passes 70 watts with an i3 under load. A 650VA UPS therefore holds this tower and a 22-inch monitor for roughly ten to fifteen minutes, which is long enough to save open work and shut down cleanly during a Kenya Power interruption. Mascom International stocks UPS units at the Kimathi Street counter. Pair one with the desktop if your building sits on a line that cuts frequently.
Technical Specifications
Processor Architecture and Real-World Speed
- 9th Generation Intel Core i3 runs four cores at a 3.6GHz base, climbing to 4.2GHz under load.
- The 65W chip carries 6MB of cache, which keeps large spreadsheet formulas and browser tabs answering quickly.
- Four cores and four threads suit accounting, payroll, and point-of-sale software rather than video rendering work.
- The Intel B360 chipset feeds the processor SATA and PCIe lanes, leaving clear room for later upgrades.
Memory Configuration and Multitasking Headroom
- 8GB of DDR4 ships installed, enough for roughly twenty browser tabs alongside Excel and an accounting package.
- Two DIMM slots accept up to 64GB in total, so the desktop grows as the workload grows.
- The i3 processor clocks memory at 2400 MT/s, which is Intel's rated speed for this particular chip.
- Adding a second matched 8GB module enables dual-channel mode and raises integrated graphics throughput measurably.
- Both memory slots are customer accessible, so a technician completes a RAM upgrade in under ten minutes.
Storage Capacity and Upgrade Paths
- The 500GB 7200RPM SATA hard drive holds roughly 100,000 office documents plus a decade of accounting backups.
- The drive uses a SATA 6.0Gb/s interface with a 32MB buffer and an 11ms average seek time.
- One free M.2 2280 slot takes a PCIe NVMe SSD, cutting Windows boot and application load times sharply.
- Three SATA ports and two internal drive bays allow a second disk dedicated to daily backups.
- A 9.5mm slim optical bay sits at the front for units configured with a DVD writer from the factory.
Graphics Output and Multi-Monitor Support
- Intel UHD Graphics 630 is built into the processor, so no separate card is needed for office duty.
- The DisplayPort 1.2 output drives a 4K panel at 4096 x 2160 pixels and 60Hz refresh.
- A VGA port handles the older monitors and projectors still common in Kenyan boardrooms and classrooms.
- Integrated graphics support up to three displays, useful for traders or dispatchers watching several dashboards at once.
- A low-profile card in the PCIe x16 slot adds capability for AutoCAD viewing or light design work.
Connectivity and Port Layout
- Four USB 3.1 Gen 1 ports move a 4GB video file to a flash disk in about two minutes.
- Four rear USB 2.0 ports run keyboards, mice, receipt printers, and barcode scanners without an external hub.
- Gigabit Ethernet through a Realtek RTL8111HSH controller connects straight to office fibre from Safaricom or Zuku.
- A free M.2 2230 slot accepts an 802.11ac Wi-Fi and Bluetooth combo card where cabling is impractical.
- A front headset jack plus rear line-in and line-out cover calls, Teams meetings, and desk speakers.
Chassis Build and Internal Expansion
- The chassis measures 95 x 296 x 270mm and weighs 4.6kg, fitting beside a monitor or under a counter.
- One PCIe 3.0 x16 slot and one PCIe 3.0 x1 slot accept network, capture, or graphics cards.
- The 180W 80 PLUS Gold supply runs at 90 percent efficiency at half load, trimming monthly electricity costs.
- Rated for 5 to 35 degrees Celsius operation, covering Mombasa and Kisumu office temperatures through the year.
- Idle noise measures 23 decibels, quiet enough for a shared reception desk or a small consulting room.
Security Features and Data Protection
- An Infineon TPM 2.0 chip stores encryption keys in hardware and unlocks the upgrade path to Windows 11.
- HP BIOSphere Gen5 restores damaged BIOS firmware automatically, cutting downtime when a power cut corrupts the boot code.
- Power-on and setup passwords block casual access on shared machines in cyber cafes and reception areas.
- A cable lock slot and padlock loop anchor the tower to a desk in open-plan offices.
- HP Secure Erase wipes drives to the NIST 800-88 Clear standard before a machine changes hands.
