What counts as an AI PC?
The term covers two different machines. Laptops sold as “AI PCs” have a small chip for light features such as live captions. The machines in this guide are desktops built around a powerful graphics card, so that chatbots, document assistants and image generators run entirely on your own hardware. Our glossary explains the difference: AI PC.
What to ask any builder
- How much memory does the graphics card have? This is the spec that decides which AI models will run. 12GB is the entry point, 16GB suits most small offices, and 24GB to 32GB runs the strongest open models. See GPU & VRAM.
- Are the power supply and cooling sized for that card? High-end cards draw a lot of power and run hot. An undersized power supply is a common cause of crashes.
- Will you install and test the AI software? Drivers and tools such as Ollama or LM Studio take time to set up. Some builders hand over a machine that is ready to run models, and others hand over bare Windows.
- What does the warranty cover, and where do I bring the machine? One warranty for the whole PC is simpler than separate claims for each part.

Dreamcore: custom desktops and creator workstations
Dreamcore builds custom PCs and creator workstations to order, with stress testing before delivery and local support. Its marketing is aimed mainly at gamers and creators, so tell them which AI models you plan to run and ask for a build specified around graphics card memory.
Armaggeddon PC: ready-specified AI workstations
Armaggeddon PC lists builds sold specifically as AI workstations, from under S$5,000 up to about S$14,000 for a dual-card Threadripper system. Several of them use AMD Radeon AI PRO cards instead of NVIDIA, so check that the software you plan to use supports them.
BreakFixNow: built around your AI workload
BreakFixNow offers a custom AI workstation service that covers choosing the parts, assembly, and installing the operating system, graphics drivers and AI tools, so the machine arrives ready to run models. It builds single-card machines as well as dual and quad graphics card systems, with entry builds from about S$3,500.
Affordable Laptop Services: the budget route
Affordable Laptop Services sells local AI desktops from S$600, built around graphics cards with 8GB to 12GB of memory. Choose a 12GB build, which is the least you want for a useful private chatbot. This is a low-cost way to test whether local AI suits your business before spending more.
PhoneDoctor: upgrade the PC you already have
If your office already has a decent desktop, you may not need a new machine. PhoneDoctor repairs and upgrades desktops and gaming PCs at its Parkway Parade, Bugis Village and AMK Hub stores, including graphics card, power supply, RAM and SSD upgrades. It checks that your motherboard and power supply can take the new parts first, stress tests the machine before handover, and gives a 90-day warranty on the part and the work. It is the walk-in option for turning an existing PC into an AI PC.
Build new or upgrade?
AI PC FAQs
The businesses in this guide list entry machines from about S$600, custom AI workstations from about S$3,500, and single RTX 5090 workstations at roughly S$6,700. Multi-card systems for teams cost well over S$10,000.
Often, yes. A desktop tower with enough space, cooling and a strong enough power supply can take a new graphics card. Ask a technician to check compatibility before you buy the card.
Usually not. Those laptops handle light AI features. Running a capable chatbot or image generator locally needs a graphics card with at least 12GB of memory.
Not strictly, but most AI tools are built for NVIDIA first, so it is the lowest-hassle choice. AMD cards can offer more memory for the money. Confirm that your software supports them.
The bottom line
Start with the graphics card memory you need and work back from there. Upgrade an existing desktop if it can take the card, buy a budget build to experiment, and commission a full workstation only when AI is part of daily work. Whoever you choose, get the software set up and tested before you take the machine home.
