The organisations we supply in Washington, D.C.
Government contractors and professional services across the District run the densest concentration of procurement-driven IT buying in the country. That work is documentation-heavy: a quotation has to carry exact manufacturer part numbers, stated condition and stated availability so it can sit in a file, be compared against competing quotes and survive review months later. A quote that says “refurbished server, 1 each” is a quote that gets questioned.
Associations, non-profits and policy organisations concentrated here run lean IT teams with long asset lifecycles, which makes parts for platforms already in service more useful than replacement systems.
Higher education and research at Georgetown, George Washington, Howard, American, Catholic, Gallaudet and UDC adds research computing storage, tape archive and campus procurement on purchase orders.
Healthcare across the District’s hospital systems and clinics runs patient identification, wristband and specimen labelling at scale, plus imaging archives that grow continuously and are read far more than written.
Museums, libraries and cultural institutions add long-retention digital preservation storage, where the archive has to remain readable for decades rather than quarters, and hospitality and retail across the District run POS receipt printers hard through conference and tourist seasons.

Getting the part right the first time
Most returns are compatibility, not quality, and the same five things cause almost all of them.
Drive carriers. A drive without the right caddy will not go in the bay. Carriers are chassis and generation specific — an HPE Smart Carrier from one generation does not fit another — and empty bays rarely ship with them. This is the most common omission in a drive order, which is why we stock caddies and trays alongside the drives.
Sector format. 512n, 512e and 4Kn are not interchangeable in an array, and the problem usually surfaces during a rebuild rather than at installation.
Memory rank and type. RDIMM and LRDIMM do not mix in the same system, and populating more ranks per channel can force the whole bank to downclock — DDR4-3200 modules running at 2933 or 2666 because of population rules, not because the modules are wrong.
Processor pairing. Both sockets need matching models, and a CPU upgrade frequently needs a BIOS level and sometimes a different heatsink.
Transceiver coding. Many switches only accept transceivers coded for that vendor, and an uncoded SFP+ is simply refused.
Tell us the server, array, switch or printer the part is going into and we check all of this before anything ships.
Urban delivery, secure buildings and older equipment rooms
Three things shape deliveries and installations in the District more than anywhere else we ship.
Building access. Loading dock restrictions, delivery windows, freight elevator booking, certificates of insurance and advance notice are routine here and frequently add a day regardless of the service purchased. Federal buildings, secure facilities and many commercial towers need the delivery scheduled and the driver cleared in advance. Tell us the access requirements when you order rather than after a failed delivery.
Older equipment rooms. A great deal of District IT lives in converted closets and basement rooms in old buildings, with marginal cooling and limited airflow. Equipment there runs warmer than the same equipment in a purpose-built room, which shortens drive life and causes throttling. If the room is warm, that is a data point worth telling us before you specify a dense configuration.
Summer humidity and power. District summers are humid, and building power in older stock sees sags and brief outages during heavy load. A UPS with working batteries matters, and batteries should be replaced on schedule rather than on failure and tested under real load — a self-test draws far less than a real outage.
Shipping to Washington, D.C.
The District is on the eastern seaboard corridor from our West Palm Beach facility, and standard ground service reaches every address well — it is a small geography and nothing in it is remote. Expedited service is available throughout. The variable is building access rather than distance, which is why we ask about docks, windows and clearance up front.
Purchase orders and District procurement
Organisations here run heavily on purchase orders, and the documentation standard is higher than in most markets. Universities, hospital systems, District agencies, contractors, associations and non-profits all require a supplier who can accept a PO, supply a formal quotation with part-level detail, complete vendor registration and supply a W-9.
Tech Seller USA accepts purchase orders from organisations and offers Net-30 terms on approval. Every quote is line by line, with the exact manufacturer part number, the condition and the availability stated on each line, so a procurement file can be evaluated without follow-up and defended later.
Request a quote for delivery in Washington, D.C.
Send the part numbers or the server, array, switch and printer models, plus any building access requirements. We confirm compatibility before anything ships.

Procurement and documentation
Can District agencies and universities order on a purchase order?
Yes. We accept purchase orders from organisations, offer Net-30 on approval, and complete vendor registration forms and W-9s as required.
Do you supply government contractors?
Yes, with the part-level quotation detail that contract documentation requires — exact manufacturer part number, condition and availability stated on every line.
Why does part-level quote detail matter for procurement?
Because the quote has to sit in a file, be compared against competing quotes and survive review months later. A quote that says “refurbished server, 1 each” is a quote that gets questioned.
Can you quote against a bill of materials?
Yes. Send the list with part numbers, quantities and the target system for each line, and you get it back priced per line.
How long is a quote valid?
We state a validity period on every quote. Ask for longer if your approval chain needs it and we will tell you what we can hold.
Can you complete vendor registration?
Yes, along with W-9s and any supplier forms your organisation requires.
Is sales tax applied in the District?
Sales tax is applied where we are required to collect it. If your organisation is tax exempt, send your exemption certificate before ordering.
How quickly do you respond to a quote request?
Our target is one business hour, Monday to Friday, 9:00 AM to 6:00 PM Eastern — the same time zone as you.
Delivery, building access and equipment rooms
Do you ship to Washington, D.C.?
Yes, to every address in the District.
How long does delivery to the District take?
The District is on the eastern seaboard corridor from West Palm Beach and standard ground reaches every address well. The variable is building access rather than distance.
Do you have a warehouse in Washington, D.C.?
No. We ship from West Palm Beach, Florida, and we would rather state that plainly than imply a local presence we do not have.
Can you deliver to buildings with dock restrictions or delivery windows?
Yes. Tell us the requirements when you order — dock hours, freight elevator booking, certificate of insurance, advance notice — rather than after a failed delivery.
Can you handle federal and secure facility deliveries?
Yes. Those deliveries frequently require scheduling, advance driver details or an escort. Tell us the process and we will work to it.
Our equipment room is warm. Does that change what I should buy?
It can. Converted closets and basement rooms with marginal cooling run equipment warmer than a purpose-built room, which shortens drive life and causes throttling. Tell us before you specify a dense configuration.
Why is my server slow with no errors showing?
Frequently thermal throttling. Processors reduce speed to stay within limits and report no fault. Check intake temperature, fans and air baffles — and check the RAID cache battery, which causes the same symptom for a different reason.
Do power sags and brief outages damage IT hardware?
Yes. Repeated sags and outages shorten the life of drives, controllers, printers and network hardware, and older building stock sees more of both.
How often should UPS batteries be replaced?
On schedule rather than on failure, and test under real load — a self-test draws far less than a real outage and can report healthy on a battery with little runtime left.
Storage, archives and retention
What storage suits long-retention digital archives?
High-capacity CMR nearline drives in a double-parity array, with LTO tape behind them. Archives grow continuously and are read far more than written, and tape remains the practical answer for long retention.
What storage suits research computing datasets?
The same shape — capacity-optimised nearline in a double-parity array with tape behind it, and flash only where the workload actually needs the latency.
Do you supply LTO tape drives and media?
Yes — LTO-6, LTO-7, LTO-8 and LTO-9 drives and media, plus autoloaders and libraries from HPE StoreEver, IBM, Quantum and Overland.
Which LTO generations are backwards compatible?
LTO drives generally read two generations back and write one generation back, with limits that changed from LTO-8 onward. Tell us the drive and the media you hold before you buy either.
Do you supply complete servers?
Yes — HPE ProLiant DL360 and DL380 Gen9 and Gen10, Dell PowerEdge R630, R730, R740 and R750, Lenovo ThinkSystem and Supermicro, as complete systems and as parts for specific models.
Can you supply parts for a platform we already run?
Yes, and for a lean IT team with long asset lifecycles that is frequently better value than a replacement system. Tell us the model and generation.
Hard drives and SSDs
What enterprise hard drive capacities do you stock?
600GB 15K SAS, 900GB SAS, 1.2TB, 1.8TB and 2.4TB 10K SAS, and 4TB, 8TB, 10TB, 12TB, 16TB and 20TB nearline drives, in 12Gb/s SAS and 6Gb/s SATA.
Which drive brands do you carry?
Seagate Exos, Western Digital Ultrastar and Toshiba, plus vendor-coded HPE, HP, Dell, IBM, Lenovo and NetApp stock.
What is the difference between 15K, 10K and 7,200 RPM drives?
Spindle speed trades capacity for latency. 15K SAS suits transactional workloads, 10K is the general-purpose middle, and 7,200 RPM nearline gives the most capacity per bay for archives.
What does nearline SAS mean?
A 7,200 RPM high-capacity drive with a SAS interface rather than SATA. You get capacity economics with SAS queueing and dual-port capability.
What enterprise SSD capacities and brands do you carry?
1.92TB, 3.84TB and 7.68TB in 12Gb/s SAS, 6Gb/s SATA and NVMe U.2, plus M.2 — Samsung, Micron, Intel, Seagate Nytro, Kioxia and vendor-coded HPE and Dell.
What is the difference between read intensive and mixed use SSDs?
Endurance. Read intensive drives are rated around 1 DWPD; mixed use is typically 3 DWPD for databases and virtualisation. A read intensive drive in a write-heavy role wears out early.
What do DWPD and TBW mean?
Drive writes per day and terabytes written — how much can be written over the warranted life. Match the rating to the workload.
What is power loss protection and why does it matter?
Capacitors that let an SSD complete in-flight writes when power is lost. It is the difference that matters most between consumer and enterprise flash, and it matters more in buildings that see power sags.
What is U.2 and how does it differ from U.3?
Both are 2.5 inch NVMe form factors. U.3 backplanes accept U.2 drives, but U.2 backplanes do not accept U.3 — the compatibility runs one way only.
What is sector format and why does it matter?
512n, 512e and 4Kn describe how a drive presents its sectors. Mixing formats in one array is refused or unpredictable, and it frequently surfaces during a rebuild rather than at installation.
Should I avoid SMR drives in an array?
Yes, always. SMR write performance collapses part-way through sustained writes, and a rebuild onto an SMR drive can fail outright. We state CMR or SMR on every listing.
Can you tell me the drive hours before I buy?
Yes. The drive reports it exactly and we check before listing.
Controllers, caddies, rails and spares
Do you supply RAID controllers?
Yes — Dell PERC H730, H730P, H740 and H965i, HPE Smart Array P440ar and P408i, plus LSI and Broadcom HBAs and QLogic and Emulex fibre channel HBAs.
Do you supply RAID cache batteries and capacitor packs?
Yes. This is the part that fails silently — the controller drops the array into write-through and performance falls off with no obvious error.
What is an IT mode HBA and when do I need one?
A host bus adapter that passes drives through to the operating system without RAID abstraction — an LSI 9207-8i or 9300-8i, for instance. Software-defined storage and ZFS need it.
Do you supply drive caddies and trays?
Yes — Dell drive caddies and HPE Smart Carrier trays, plus drive blanks. We stock them alongside the drives.
Will an HPE Smart Carrier from one generation fit another?
No. Smart Carrier trays changed across generations and do not cross. Tell us the server model and generation.
Do you supply server rails, risers, backplanes, fans and heatsinks?
Yes, all of them. Rails are chassis and rack specific; risers determine which PCIe slots are usable and at what lane width; heatsinks are frequently processor and chassis specific.
Memory, processors, power and networking
What server memory do you stock?
16GB, 32GB, 64GB, 128GB and 256GB DDR4 RDIMM and LRDIMM registered ECC in DDR4-2400 PC4-19200, DDR4-2666 PC4-21300 and DDR4-3200 PC4-25600, plus DDR5-4800 and DDR5-5600 and DDR3-1600 PC3-12800.
Which memory brands do you carry?
Samsung, Micron, SK Hynix, Kingston and Crucial, plus HPE and Dell coded modules where the platform expects them.
What is the difference between RDIMM, UDIMM and LRDIMM?
RDIMM buffers the address and command lines, LRDIMM buffers the data lines too and allows much higher total capacity, and UDIMM is unbuffered. They do not mix in the same system.
Why is my DDR4-3200 memory running at 2666?
Population rules. Filling more ranks or more slots per channel forces the bank to downclock, and the processor also has a maximum supported speed.
Do you supply Xeon E5 v3 and v4 processors?
Yes, along with Xeon Scalable Bronze, Silver, Gold and Platinum from 8 to 28 cores, and AMD EPYC and Opteron.
Can I mix different Xeon models in a dual socket server?
No. Both sockets need matching models. A mismatched pair either refuses to boot or runs on one socket.
Do you supply server power supplies?
Yes, by wattage — 495W, 750W, 800W, 1100W and above — for HPE, Dell and Supermicro platforms.
Can I mix power supply wattages in one server?
Generally no. Redundant supplies should match on wattage and usually on part number; a mismatched pair commonly logs a fault and may not provide redundancy at all.
Do you supply rack PDUs and UPS units?
Yes, including UPS battery replacements.
Do you supply SFP+ and QSFP transceivers?
Yes, including SFP-10G-SR, QSFP+ and QSFP28.
Will any SFP+ transceiver work in my switch?
Often not. Many switches only accept transceivers coded for that vendor and simply refuse others. Tell us the switch make and model.
Do you supply 10GbE network adapters and switches?
Yes — Intel X520 and X710, Mellanox ConnectX and Broadcom adapters, plus Cisco Catalyst and comparable PoE+ and 10GbE switches by port count.
Labelling, healthcare, POS and printheads
Do you supply label printers for District healthcare?
Yes. Zebra and SATO printers for patient identification, wristband and specimen labelling, plus genuine replacement printheads.
Should specimen labels be direct thermal or thermal transfer?
Thermal transfer with a resin ribbon for anything with a long life. Direct thermal fades with heat, light and time, and a specimen label that becomes unreadable means a sample that cannot be identified.
How many spare printheads should an operation hold?
At least one per printer model in continuous use. Printheads are consumables with a rated life measured in linear distance printed, not parts that fail unexpectedly.
How do I know which printhead my printer needs?
Read the part number off the existing printhead or the printer label. Printheads differ by resolution for the same printer model and do not cross between models.
There is a white line through every label. What is wrong?
A dead heating element in the printhead. It appears in the same position on every label, does not heal, and more elements will follow.
Why is my printer skipping labels?
Calibration. The printer detects label boundaries with a sensor, and changing media size, liner or gap requires recalibrating.
Why is my label print faded?
Check a dirty printhead first, then darkness setting, then whether the ribbon type suits the media, then printhead wear. Do not simply raise the darkness.
Do you supply scanners for asset tracking and inventory?
Yes. Zebra, Honeywell and Datalogic handhelds and rugged mobile computers, supplied with the correct interface cable for your host system.
Will a 1D laser scanner read 2D codes?
No. Data Matrix and QR codes are 2D and require an imager. A 1D laser cannot read them at all.
Do you supply POS receipt printers for District retail and hospitality?
Yes. Epson, Star Micronics and Bixolon receipt printers, including impact printers for kitchens where heat and grease make thermal receipts unreadable within hours.
Condition, testing and returns
What condition is your hardware in?
We state the condition on every line. Ask for the specific condition, the testing performed and the drive hours where applicable.
Is your hardware tested?
Testing is performed where applicable and we will tell you what was done. A power-on check and a full surface test are different things and we do not describe one as the other.
What is your return policy?
30 days. Raise a problem promptly — the sooner it is raised, the more options there are.
Should I test hardware when it arrives?
Yes, before it goes into production.
Will you tell me if I am buying the wrong thing?
Yes. Several of our guides recommend against a purchase where the workload does not justify it, and we apply the same approach to quotes.
Do you buy decommissioned hardware from District organisations?
Contact us with a list of what is coming out and we will tell you what it is worth and what is worth keeping as spares.
How do I contact you from Washington, D.C.?
Call (954) 601-5103 or email sarah.jane@techsellerusa.com. Business hours are Monday to Friday, 9:00 AM to 6:00 PM Eastern.
