Custom Computer Builds in San Marcos, TX

San Marcos Computers builds custom desktop computers and gaming PCs in San Marcos, Texas. Whether you need a computer designed specifically for gaming, work, creative applications or general high-performance use, we can help you choose the components and build the system.

We offer custom computer builds for customers who want something different from an off-the-shelf computer.

Three Ways We Build Custom Computers

Our custom computer service can work in several different ways depending on what you need.

We Build a Computer for Our Inventory

San Marcos Computers builds custom desktop and gaming computers for our own inventory. These systems are designed, assembled and tested by us and are then offered for sale as complete computers.

These computers are part of our Computers for Sale inventory.

We Design and Build a Computer for You

If you know what you want your new computer to do but don't want to select and assemble all of the components yourself, we can design the system around your needs.

We can help determine the appropriate processor, motherboard, memory, storage, graphics card, power supply, case and other components based on the intended use of the computer.

Once the configuration is established, we purchase the necessary components, assemble the computer and test the completed system.

You Supply the New Parts

You can also provide your own brand-new computer components and have us assemble the system.

This can be useful if you have already purchased the parts or have selected the components yourself but would rather have an experienced technician handle the assembly.

We can assemble the computer, connect the components, configure the system and test the finished build.

Custom Gaming Computers

Gaming computers often require more careful component selection than a basic desktop.

The processor, graphics card, power supply, cooling, memory and storage all need to work together as a balanced system.

We can build gaming computers around the games you play, the resolution you want to use and the performance you are looking for.

We can also help determine whether upgrading an existing gaming computer makes more sense than building a new one.

Build a Computer Around What You Actually Need

One advantage of a custom computer is that the system can be designed around the way you actually use it.

Depending on your needs, a custom system might be designed for:

• PC gaming
• Home and office use
• Photo and video editing
• Music production
• CAD and engineering applications
• Streaming
• Content creation
• High-performance multitasking
• Other demanding applications

Not everyone needs the most expensive components. The goal is to build a computer appropriate for the intended use rather than simply adding expensive hardware that provides little practical benefit.

Component Selection

A custom computer is more than a collection of individual parts. The components need to be compatible with each other and appropriate for the intended use.

Depending on the build, components can include:

• Processor (CPU)
• Motherboard
• Memory (RAM)
• Graphics card (GPU)
• Solid-state storage
• Additional storage
• Power supply
• Computer case
• CPU cooling
• Additional case fans
• Operating system

Gaming PC Graphics Cards

The graphics card is one of the most important components in many gaming computers.

The appropriate graphics card depends on the games you play, monitor resolution, desired settings and overall system configuration.

We can help select a graphics solution that makes sense for the rest of the computer rather than choosing a graphics card in isolation.

Storage Options

Modern custom computers can use different combinations of solid-state storage and additional drives.

We can help determine how much storage you need and whether your system should use a single high-capacity SSD or a combination of storage devices.

Memory and Performance

The amount of RAM needed depends on what you do with the computer.

A gaming computer, office computer and workstation used for demanding creative applications may have very different memory requirements.

We can configure the system based on the intended workload rather than simply maximizing the amount of memory.

Power Supply Selection

The power supply is an important part of a custom computer, particularly when using a high-performance graphics card or multiple power-hungry components.

We select a power supply appropriate for the components in the system rather than treating the power supply as an afterthought.

We Build and Test the Computer

Once the components have been selected, we assemble the computer and verify that the major components are functioning correctly.

Depending on the build, testing can include checking system operation, memory, storage, graphics hardware, cooling and other components.

The goal is to provide you with a properly assembled and tested computer rather than a box of components that still needs to be put together.

Customer-Supplied Parts

If you already purchased brand-new components, you can bring them to us for assembly.

Before beginning the build, we can check the parts for compatibility and identify obvious issues with the proposed configuration.

Customer-supplied parts must be new and appropriate for the intended system. We do not guarantee compatibility simply because individual components were purchased separately.

Custom Computer Builds vs. Computer Upgrades

Sometimes you don't need an entirely new computer.

If your existing desktop is still a good platform, replacing or upgrading individual components may provide the improvement you need.

Our Hardware Repair & Upgrades service can help with compatible upgrades such as SSDs, RAM, graphics cards and other hardware.

If the existing computer has reached the point where several major components need to be replaced, a new custom build may make more sense.
