All used components from PCSP go through a thorough inspection and testing process. Our technicians are experts with this equipment, and they can be trusted to spot any defective equipment before it leaves out facility. All components also come with a standard 90-day warranty from the date of purchase. So, purchase with peace of mind knowing that you can get a full refund or replacement in case anything with the component goes wrong. Here is a quick explanation of some of the components we sell:


Think of the CPU as the computer's command center. It interprets and processes data from software and the operating system. This involves fetching, decoding, and executing instructions, either by conducting calculations, making decisions, or coordinating with other components.


Random Access Memory (RAM) is a critical component of any computer system, acting as the short-term memory that stores data for quick access by the processor. The right amount and type of RAM can significantly impact the speed and efficiency of your tasks, from simple browsing to complex computational processes. Below, we will demystify RAM selection, provide insights into its functions, how to choose it, and what factors to consider for optimal performance.


A Hard Disk Drive (HDD) is a data storage device used in computers to store and retrieve digital information using rapidly rotating disks (platters) coated with magnetic material. HDDs are known for their large storage capacities and ability to retain data even when powered off. They use a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This technology is one of the oldest and most widely used forms of computer storage due to its cost-effectiveness and ample storage size, making it a popular choice for secondary storage in personal computers and servers.


An SSD, or Solid-State Drive, is a storage device that uses integrated circuits to store data. Unlike traditional Hard Disk Drives (HDDs), which store data on spinning metal platters and use a moving read/write head, SSDs have no moving parts. This results in faster performance, increased durability, and less power consumption compared to HDDs.

Trays and Adapters

Server trays (or caddies, carriers) are small sleds that hold a hard drive which slides into the server and connects to the backplane. To install an HDD or SSD in your machine, you will need a compatible tray. Trays are brand specific and must be matched with the same form factor as the bays on your server.

Graphics Cards

A Graphics Processing Unit (GPU) is a specialized electronic circuit designed to render images and videos to a computer’s display. GPUs accelerate the creation of images by performing parallel operations, which makes them highly efficient for graphics rendering and computation-heavy tasks. They consist of thousands of smaller cores capable of handling multiple tasks simultaneously, making them indispensable for tasks like gaming, 3D rendering, and scientific simulations.

RAID Cards

Redundant Array of Independent Disks (RAID) technology is a cornerstone of data management and protection strategy in both servers and workstations. RAID cards, also known as RAID controllers, are pivotal components that manage this array, enhancing data integrity and performance. In this guide, we delve into the functionality of RAID cards, provide insights on how to select the right one, and discuss the critical considerations that should inform your decision.

Network Cards

A network card is a hardware element that creates the communication gateway between your server and the network. It converts data from a digital format that your server can understand to an electrical or optical signal suitable for transmission over a network, and vice versa. 

SAS Expanders

SAS Expanders play a critical role in enabling this scalability by allowing multiple Serial Attached SCSI (SAS) devices to connect to a single SAS controller card. This article will explore the functionality of SAS Expanders, guide you through selecting one for your server or workstation, and discuss essential considerations for ensuring optimal performance and compatibility.


The motherboard is the central hub of a computer, a vital component that connects all other parts of the system, enabling them to communicate and function harmoniously. From power management to data flow, the motherboard's influence is pervasive and critical to performance. In this comprehensive guide, we will illuminate the role of motherboards in various systems, detail how to select the perfect board for your needs, and outline key considerations to make an informed choice.

Power Supplies

The Power Supply Unit (PSU) is the unsung hero of computer systems, dutifully converting electrical energy into usable power for all components. Its significance extends beyond mere electricity provision; it ensures stability and longevity for sophisticated hardware. This guide is tailored to help you navigate the nuances of PSUs, making an informed selection that aligns with your system’s demands, and highlighting considerations to ensure peak performance and reliability.


Heatsinks are crucial in managing the thermal output of various components like CPUs, GPUs, and even some high-performance ICs. They come in various forms, such as active, passive, and phase-change heatsinks.

Server Rails

Server rails are integral components in the IT realm, especially when dealing with rack-mounted servers. They are essentially mounting supports that are designed to hold servers, network equipment, or other rack-mounted devices securely within a server rack.

Server Bezels

A server bezel is a component often found in rack-mounted server equipment and data centers, designed to fit over the front face of the server. Bevels have evolved in the past 20 years in terms of utility within server configurations.
