Quick answer: Singapore’s custom gaming desktop scene includes established builders AFTERSHOCK PC, Mansa Computers, and DreamCore, alongside more recently incorporated entities Invader PC (2021) and Define PC (2022, though it cites an operating history back to 2016). All five businesses below have been checked against the ACRA-sourced public business registry, with retail/showroom addresses independently verified against each business’s own current site rather than assumed from the original listing.
A gaming desktop is a box you’ll sit next to for years. The real question isn’t specs, it’s what you’re paying for behind the sticker—build quality, support, and whether the assembly charge is a fair markup or an atas premium. This list sorts the shops that understand value from the ones that just understand hardware.
1. AFTERSHOCK PC
AFTERSHOCK PC Pte. Ltd. (UEN: 201228133D) is a custom PC builder that has won Best Gaming Desktop Brand from Hardwarezone multiple times. ACRA registry records confirm this UEN as a live company, incorporated 15 November 2012, with a stated principal activity of custom computer manufacturing, at the Bendemeer Road address confirmed below. Correction: the originally-listed Suntec City Mall showroom has closed — Hardwarezone and the business’s own Facebook page confirm the Suntec outlet ceased operations in February 2026. AFTERSHOCK now operates a larger Experiential Centre at #01-05 in the same B-Central building as its service centre, confirmed via the business’s own current site.
Products or Services
Custom gaming PCs, workstation PCs for creators, and enterprise solutions including GPU servers.
Recognition
Best Gaming Desktop Brand from HardwareZone, seven years running, and Singapore’s Best Customer Service Award (2023/24) from The Straits Times.

- Website: AFTERSHOCK PC
AFTERSHOCK has shifted to Bendemeer, leaving behind the mall rental markup, so the build charge stays honest. Their multiple Hardwarezone awards tell you they’ve been doing this right for a long time. Walk in, spec out a machine, and you’ll leave with a system that feels like a work tool, not a showpiece. Good for the buyer who wants predictable, no-nonsense reliability.
2. Mansa Computers
Mansa Computers Pte. Ltd. (UEN: 201810609R) offers curated and custom gaming PCs. ACRA registry records confirm this UEN as a live company, incorporated 28 March 2018, with a stated principal activity of computer hardware/software retail (secondary: repair services). The registered office is #01-23 in the same Focus One building as the showroom below (#01-22) — an adjacent-unit back-office pattern; the showroom address was independently confirmed via the business’s own current site.
Products or Services
Curated collections including Gamer PCs, Pink PCs, Office PCs, and Streamer PCs, plus full custom builds from Tiny (ITX) to EATX sizes.

- Website: Mansa Computers
You’re not paying for a glitzy showroom here. Mansa keeps it simple: a working office with a display area, which means your money goes into the parts list and the assembly work. See the component boxes, confirm the spec, then they build. Suits the buyer who wants to physically verify what’s inside the case. Weekday visit makes sense — less queue, more time to ask the right questions.
3. DreamCore
DreamCore Private Limited (UEN: 201731282M) builds custom PCs from a 10,000-square-foot Dream Centre and offers corporate IT solutions. ACRA registry records confirm this UEN as a live company, incorporated 1 November 2017, with a stated principal activity of computer hardware/software retail, at the address below exactly. Corporate solutions include workstations for 3D modelling and multi-monitor setups; DreamCore’s site references its own warranty and service programme without stating specific terms on the pages checked.
Products or Services

Contact Information & Location
- Showroom: 55 Kim Chuan Drive, #09-01, Singapore 537098

- Operating Hours: Mon – Fri: 11am – 7pm; Sat: by appointment only; closed Sun and public holidays
- Website: DreamCore
DreamCore runs a 10,000-square-foot Dream Centre, so they’re not a backyard operation. They handle corporate workstations, which means their assembly line has to meet business-grade consistency. For a home gamer, that same rigour means your rig won’t be put together by someone in a rush. Worth a visit if you want the confidence of an outfit that builds machines for professionals who can’t afford downtime.
4. Invader PC
Invader PC Pte. Ltd. (UEN: 202130055E) builds custom gaming desktops with a focus on the latest hardware. ACRA registry records confirm this UEN as a live company, incorporated 27 August 2021, with stated principal activities of custom computer manufacturing and hardware retail. The registered address matches the location below, with the unit number confirmed via the business’s own current site (#01-19/20/21).
Products or Services
Custom gaming desktops featuring the latest hardware, built for both gamers and professionals with flexibility for future upgrades.

- Operating Hours: Mon – Sat: 10am – 7:30pm
- Website: Invader PC
Invader PC’s setup at #01-19/20/21 shows they’ve taken multiple units, which usually means volume—and that can translate to better part availability. They focus on the latest hardware, so if you want a build with the newest GPU or CPU without waiting weeks, this is where you go. Their custom configurations are specked by people who actually game, not just assemble. Steady choice for the enthusiast on a timeline.
5. Define PC
Define PC Pte. Ltd. (UEN: 202230266C), operating since 2016 per its own materials, offers pre-built and custom gaming desktops. ACRA registry records confirm this UEN as a live company, incorporated 28 August 2022 (the current Pte Ltd entity’s incorporation date, distinct from the business’s own longer operating history), with a stated principal activity of computer hardware retail (secondary: equipment rental), at the address below exactly.
Products or Services
Pre-built and custom gaming desktops for gaming, content creation, and professional applications.
Contact Information & Location
- Service Centre: 8 Ubi Rd 2, #03-05, Singapore 408538
- Contact: Hotline +65 6012 2904 or +65 6219 3260; WhatsApp +65 9716 9704 (all three numbers confirmed via the business’s own contact page)
- Email: [email protected]
- Operating Hours: Mon – Fri: 10am – 6pm; Sat – Sun: 12pm – 3pm
- Website: Define PC
Define PC has been operating since 2016, long before the current company entity, so there’s institutional memory that a fresh start-up can’t fake. They offer both pre-built and custom rigs, and their secondary business in equipment rental suggests they build machines tough enough to be loaned out. That’s a good sign for longevity. The showroom in Ubi is straight-up—you’ll see what you’re paying for without the glitz.

About this list
Each business’s Unique Entity Number (UEN) was individually checked against the ACRA-sourced public business registry — all five resolve cleanly to their stated businesses. Because a registered address can remain correct even after a showroom moves or closes, every retail/showroom address here was additionally cross-checked against each business’s own current website. This surfaced a genuine, significant change: AFTERSHOCK PC’s Suntec City showroom closed in February 2026 and has been replaced by a larger Experiential Centre at its Bendemeer Road building — corrected above. DreamCore’s phone number and Saturday hours were also found to have changed.
Disclaimer: Information is current as of July 2026 and compiled from publicly available sources, including each business’s own website and the ACRA-sourced public business registry. While we have made every effort to ensure accuracy, details such as pricing, hours, and showroom locations may change — please confirm directly with the retailer before visiting. If you find any errors or have concerns about the content, please let us know so we can address them promptly.
