I recently chance upon ByteSize from a friend. To put it simply, they are a team of dedicated PC specialist who strive to understand their clients’ needs. Utilising their expertise, they thoughtfully select parts to cater to the requirements while not forgetting the discussed budget. Being a newbie in this gaming PC field, I had a lot of queries about the individual parts and they were able to explain it such that it is clear and concise, leaving you with salient points that are important to note. They were also super responsive and willing to help in the after sales stage. All in all, a pleasant and swift process. Quality builds, quality customer service. 10/10 Would recommend them to anyone out there who is looking to own their first PC, or even planning to upgrade their current gaming rig. Great job Bytesize!

Lazy at building your own? You’ve come to the right place! After months of research I finally decided to order at ByteSize and they did not disappoint. Like many others have said with their 5-star reviews, the quality of not just the build itself but customer service and candid communication is just above and beyond. Thank you so much for putting so much care and pride in what you do. 🦾

I have no idea how I found this shop. But they are selling what I wanted. It was a smooth transcation and the cards are laid out honestly by the seller. I have not compared prices before I decided to buy as I doubt it will be much of a difference. Overall the build quality and low-noise setup was better than I expected and I will use/recommend they again if I need another custom built.

Was browsing for laptops and desktop for home use, and decided to go for custom PC. After looking at other websites, ByteSize suits what I am looking for. Zhi An recommended a better cpu cooler and ram memory based on your choice of items. Didnt know they provide building and setup of the PC. the constant update from them keeps me assurance. He also helped to put those necessary items in a box. the PC comes together with the parts packaging as well. Overall, i am satisfied with the product and the service.

Had a great experience getting a custom pc from ByteSize. Service was top notch with Zhi An providing insightful recommendations and regular updates with pictures throughout the building process. He even accommodated my tight schedule over the weekend for the delivery. Appreciate the after sales support. Highly recommend!

I ordered my PC online here. The staff were quick to help me with any missing parts in my order and also frequently updated me with how my system was coming together. I got my PC delivered with minimum hassle, very good service.

I am rather new to PC assembly and I followed what my sister wanted me to build for her. Turns out that the processor did not have a CPU fan and ByteSize saved me by giving me a spare CPU fan. They even went all out to explain why the processor series comes without a fan and what sort of processor type I should get instead. I decided to write this review just for their friendliness, and going miles further to help out even without any business transactional benefits. I will definitely support their shop again in the future. My sister likes her new setup 🙂 Thanks again !

Bought a motherboard in 2020 from them, amazingly patient and understanding (covid delays). Had an issue troubleshooting my new setup in Feb 2024 and Zhi An was such a talent to troubleshoot and revive a minorly short circuited desktop + stress test some parameters to check for functionality. No regrets would definitely go back to them for any components, build and troubleshooting in the future. You're in extremely talented and resourceful hands.

Frequently Asked Questions (FAQs)

I can't decide on which parts I should get.

You will most often see the greatest performance benefits by focusing on your (i) Graphics Processing Unit (GPU); and (ii) Central Processing Unit (CPU) as these two components play the biggest roles in determining your overall system performance and capability. Next, you should ensure that you have sufficient RAM capacity for your applications.

Chat with us and we'll be more than happy to guide you in choosing the components that would best serve your needs for a Gaming PC and/or Workstation. 

What's the difference between Small Form Factor (SFF), Mid Towers and Full Towers?

Our Bytes are segregated into 3 different categories based on their physical dimensions in increasing order: (i) Small Form Factor (or commonly abbrieviated as SFF); (ii) Mid-Towers which utilise micro-ATX motherboards; and (iii) Full-Towers which utilise ATX motherboards.

SFF systems are suitable for users with physical constraints on the placement of their systems. It's advisable to add additional cooling to ensure sufficient ventilation for a SFF system due to their limited internal airflow.

Mid-Tower (micro-ATX) systems offers the greatest balance and flexibility between physical footprint and internal hardware components. Plus, they offer the best bang for your buck!

Full-Tower (ATX) systems are the ideal centerpiece of every gaming or workplace set-up. They sport the largest hardware compatibility and internal airflow for keeping the system cool under extreme and stressful conditions.

Do you provide all of the PC components boxes and packaging?

We certainly can! We use only brand new components in all of our Custom Gaming PCs, Desktops & Workstation builds. If you'd like to retain the PC component boxes and packaging do let us know when placing your order and we'll deliver the original packaging together with your system!
