Custom Computer Builds in San Marcos, TX

Want a computer built specifically for you? San Marcos Computers provides custom computer builds in San Marcos, Texas, including custom gaming PCs, high-performance desktop computers, workstations, and other systems designed around your needs and budget.

Whether you want us to select the components, you already know exactly what you want, or you have purchased your own brand-new parts, we can assemble, configure, and test your custom computer.

San Marcos Computers is locally owned and operated and has been serving San Marcos and Central Texas since 2010, with more than 40 years of hands-on computer service experience.

How Our Custom Computer Builds Work

There are several ways we can build a custom computer for you.

We Design, Purchase & Build the Computer

If you know what you want to accomplish but don't know which components to purchase, we can help design the system.

We can discuss how you plan to use the computer, determine the appropriate performance level, select compatible components, source the parts, assemble the computer, install the operating system and drivers, and test the completed system.

You Choose the Components

If you already know which processor, graphics card, motherboard, memory, storage, case, power supply, and other components you want, we can review the configuration for compatibility and assemble the computer for you.

Before assembly, we can help identify potential compatibility issues or component combinations that may create problems.

You Purchase Your Own Brand-New Parts

You do not have to purchase the components through San Marcos Computers to have us build your computer.

If you have purchased your own brand-new computer components, we can provide assembly and testing services, subject to the condition and compatibility of the parts.

We strongly recommend keeping all receipts, warranties, and documentation for customer-supplied components.

Custom Gaming Computers

A gaming computer should be designed around the games you actually play and the performance you want to achieve.

We can help configure systems around factors such as:

• Gaming resolution
• Graphics performance
• Processor performance
• Memory requirements
• Storage capacity
• Cooling requirements
• Power supply requirements
• Future upgrade plans

Whether you want a balanced gaming system or a high-performance gaming PC, the goal is to build a system where the major components work together rather than simply selecting the most expensive parts available.

Custom Performance & Workstation Computers

Custom computers are not just for gaming.

A custom-built system can also be designed for demanding applications such as photo and video editing, content creation, engineering and design software, development, virtualization, productivity, or other workloads that benefit from specialized hardware.

We can help select components based on the software you use and the type of work you need the computer to handle.

Choosing the Right Components

A custom computer is more than a collection of individual parts. Components need to be compatible and properly matched to the intended use of the system.

Depending on the build, we may evaluate:

• Processor (CPU)
• Motherboard
• Graphics card (GPU)
• Memory (RAM)
• Solid-state storage (SSD)
• Additional storage drives
• Power supply
• Computer case
• CPU cooling
• Case airflow
• Operating system
• Expansion requirements

Compatibility Matters

One of the advantages of having a computer professionally assembled is having someone review the entire configuration before everything is installed.

Potential compatibility issues can involve processor and motherboard compatibility, memory specifications, power requirements, physical component clearance, cooling, storage interfaces, graphics card requirements, and other factors.

We can identify these issues before assembly whenever possible.

Professional Assembly & Testing

After the components are selected and available, we assemble the system and perform appropriate testing.

Depending on the build, testing may include:

• System power and startup testing
• Hardware detection
• Memory testing
• Storage testing
• Graphics testing
• Cooling and temperature checks
• Operating system installation
• Driver installation
• System updates
• General stability testing

The goal is to deliver a properly assembled and functioning computer rather than simply putting the components together.

Customer-Supplied Parts

We can assemble computers using brand-new components supplied by the customer.

Because customer-supplied parts are purchased outside San Marcos Computers, the manufacturer's warranty and return policies generally apply directly to those components.

We recommend that customers verify return policies and retain original packaging until the completed computer has been tested.

Used, damaged, modified, incomplete, or incompatible components may not be suitable for a custom build. We will evaluate the situation before proceeding.

Custom Computer Build vs. Prebuilt Computer

A custom-built computer allows the system to be configured around your specific requirements instead of selecting from a predetermined configuration.

Depending on your needs, however, a new or refurbished prebuilt computer may still be a practical choice.

San Marcos Computers sells new and refurbished computers in addition to building custom systems. If you are unsure which option makes sense, we can help you compare the choices.

Custom Computer Builds vs. Computer Repair

A custom build is for creating or assembling a new computer.

If you already own a computer that is having problems or needs upgraded components, that generally falls under our Computer Repair services.

For example, replacing the graphics card in an existing gaming computer, upgrading RAM, replacing a failing SSD, or installing a new power supply would normally be handled as a hardware repair or upgrade rather than a new custom build.

See our Hardware Repair & Upgrades page for existing-computer upgrades.

Custom Gaming PC Upgrades

If you already have a custom-built gaming computer and want to improve its performance, we can evaluate the existing system and determine which upgrades may provide the most useful improvement.

Depending on the system, upgrades may include memory, storage, graphics hardware, cooling, power supply, or other compatible components.

We recommend evaluating the existing configuration before purchasing upgrade parts so that the new components work properly with the rest of the system.
