Lenovo ThinkCentre M90S G6 SFF U7 /16GB /512GB SSD

General

This Configuration — From the Distributor Build Sheet for 12YU001FSG

Chassis and Platform — From Lenovo PSREF

Why this page separates "the chassis" from "this unit"

Lenovo publishes its specification book per machine type, not per part number. That book is authoritative about what cannot vary — the ports, the number of memory and drive slots, the dimensions, the security slot. But it lists the processor, memory, storage, wireless card, power supply, discrete graphics, operating system and warranty term as options, because Lenovo builds the same machine many different ways. The per-part-number pages that would settle which options a given SKU carries render only inside a browser.

So rather than presenting the option list as though it described this unit, this page shows you both: the chassis table is Lenovo's, and the This Configuration table is the distributor's own build sheet for this exact part number. Anything neither source states is marked as not stated. If one item decides your purchase, ask us and we will confirm it in writing before you order.

An AI PC, but not a Copilot+ PC — and the difference is a hardware bar

Lenovo's specification book carries an AI PC Category field, and for this machine type its value is "AI PC". The processors here carry Intel AI Boost, up to 13 TOPS. Microsoft's Copilot+ tier requires an NPU of 40 TOPS or more, so this machine does not qualify, and Lenovo does not claim it does.

That matters only if your organisation is specifically buying Copilot+ hardware for the Windows features that require it. If it is, the neo 50q Gen 6 in the ordering table is the one ThinkCentre here that qualifies — at the cost of soldered, non-upgradable memory. If it is not, 13 TOPS is ample for the on-device AI features people actually use, and you keep the upgradability.

M-series or neo? The difference is real, and it is not just price

Lenovo sells both lines into the same size classes, which makes them easy to confuse on a quotation. Comparing the two specification books side by side, these are the consistent differences:

• Manageability. The M-series carries an Intel I219-LM Ethernet controller and offers vPro; the neo machines use Realtek controllers. If you manage a fleet out-of-band, that is the difference that matters
• Expansion. In the 8.2-litre chassis, the M70s takes four DIMM slots and 128 GB against the neo 50s's two slots and 64 GB, and offers an NVIDIA graphics option the neo does not
• Warranty. The M-series books publish a 3-year limited onsite base warranty option. The neo books do not publish any 3-year base term at all — only 1-year options. Where a neo machine in our range carries three years, it is a configured upgrade rather than Lenovo's base term, and we say so on the page

None of that makes neo the wrong choice — for a fleet of standard office desktops it is often exactly right, and cheaper. It makes it a choice worth making deliberately. Tell us how the machines will be managed and we will tell you which line fits.

About the warranty, precisely

Lenovo's PSREF book for this machine type publishes a 3-year limited onsite service option among its base warranty terms, alongside 1-year courier or carry-in and 1-year onsite. That is a genuine difference from Lenovo's laptop lines, where no 3-year base term exists at all.

But the term is a configuration choice, not a property of the model. Lenovo does not publish which term a given part number ships with, and the distributor build sheet for this unit records 3-year onsite. Onsite means an engineer attends the machine rather than you shipping it, which on a desktop somebody depends on daily is the more useful half. Every unit SourceIT sells also carries local Singapore warranty support and a GST invoice, and we will confirm the exact term and start date in writing before you order.

In the box, per Lenovo PSREF:

• Lenovo ThinkCentre M90s Gen 6 desktop, built to the configuration above
• USB keyboard and mouse
• Power cable
• Quick start guide and safety documentation

Lenovo does not publish a carton contents list per part number for the ThinkCentre range. The build sheet for this unit is reflected above. A monitor, and a VESA or stand mounting kit, are separate items — ask us and we will quote the whole desk rather than the box.

Lenovo ThinkCentre Ordering Information

• Lenovo PSREF — ThinkCentre M90s Gen 6 specification book (PDF)

PSREF is Lenovo's own Product Specifications Reference. It publishes per machine type rather than per part number, so this SKU does not appear inside the PDF itself — the PDF is the authority on the chassis, the ports and the option menu, and the distributor build sheet is the authority on which options this unit carries. Both are reflected above.

Is the memory upgradable, and is a slot free?

Yes. Lenovo publishes four DDR5 UDIMM slots to 128 GB for this machine type with no soldered memory. What is not published — by Lenovo or on the build sheet — is whether the 16 GB in this unit occupies one slot or both. That is the difference between a cheap upgrade later and replacing what you already own, and it is the most-asked question we get. Ask us and we will confirm the module configuration for your order.

Can I add a graphics card?

Yes. Lenovo publishes NVIDIA GeForce RTX 3050, 6 GB GDDR6 or Intel Arc A310 LP, 4 GB GDDR6, in a 155 mm by 70 mm envelope for this machine type, in a low-profile 155 mm by 70 mm envelope. Lenovo does not publish a board-power figure for either card, so if you have a different card in mind, ask us and we will check what is actually supported.

What warranty does it come with?

3-year onsite service, per the distributor build sheet for this part number. Lenovo's book for this machine type does publish a 3-year limited onsite option among its base terms, so this is within Lenovo's standard menu. Onsite means an engineer attends the machine rather than you shipping it. Every unit SourceIT sells also carries local Singapore warranty support and a GST invoice, and we will confirm the exact term and start date in writing before you order.

Is this a Copilot+ PC?

No. Lenovo's AI PC Category field for this machine type reads "AI PC", and its processors carry Intel AI Boost at up to 13 TOPS. Microsoft's Copilot+ tier requires 40 TOPS or more. The neo 50q Gen 6 in the ordering table is the one ThinkCentre here that qualifies — at the cost of soldered, non-upgradable memory.

What is the difference between the M-series and the neo machines?

Three things, consistently. The M-series carries an Intel I219-LM Ethernet controller and offers vPro, where the neo machines use Realtek controllers — that is the one that matters if you manage machines out-of-band. In the 8.2-litre chassis the M70s takes four DIMM slots and 128 GB against the neo 50s's two and 64 GB. And the M-series books publish a 3-year onsite base warranty option where the neo books publish only 1-year terms. This machine is M-series. Neither line is the right answer for everyone — tell us how the fleet is managed and we will say which fits.

What lock fits it?

A Kensington lock in a 3 x 7 mm slot. Lenovo publishes the slot dimensions as 3 x 7 mm. We stock Lenovo's cable locks; ask us and we will match the lock to the machines you actually have, which matters in a mixed fleet where the laptops take the smaller Nano slot and the desktops do not.

Can you help me choose between these?

Yes, and it is worth two minutes of your time. The machines in the ordering table above look similar and are not: some take 128 GB and some 16 GB soldered, some have an Intel NIC and vPro and some do not, some carry a 3-year onsite term and some carry one year. Tell us what the machines will run, how long you intend to keep them and how they will be managed, and we will tell you which one fits — including when the cheaper one is the right answer.
