Build your custom PC by selecting components
Everything you need to know about graphics cards before you buy.
A GPU (Graphics Processing Unit) is a chip dedicated to rendering images, video, and animations on your screen. Unlike a CPU, which handles a few complex tasks at once, a GPU excels at running thousands of smaller tasks in parallel — exactly what rendering 3D graphics, ray-traced lighting, and high-resolution video requires. For gaming, the GPU is almost always the single biggest factor in how many frames per second you get. For creative work like 3D rendering or video editing, a faster GPU dramatically cuts down processing time.
Video RAM is the GPU's dedicated memory for textures, frame buffers, and assets. Running out of VRAM causes stutters and crashes.
Measured in MHz. Base clock is the minimum sustained speed; boost clock is the peak the GPU hits under load. A higher boost clock generally means better performance, but architecture matters more than raw clock speed.
Thermal Design Power is how many watts the GPU consumes at peak. This directly determines what PSU you need. High-end GPUs (RTX 4090: 450W) require 850W+ PSUs with multiple PCIe power connectors. Always add 100–150W of headroom above your total system power draw.
How fast data moves between the GPU and its VRAM, measured in GB/s. Higher bandwidth reduces bottlenecks when textures and frame data need to be fetched quickly. This is especially important at 4K where more data is processed per frame.
The GPU's underlying design generation. Newer architectures bring better performance-per-watt, improved ray tracing, and new features like upscaling. Current generations:
Good for 1080p gaming at medium-high settings. Not ideal for ray tracing or 4K.
The sweet spot. Comfortable 1440p gaming, capable ray tracing, enough VRAM for modern titles.
For 4K gaming, max settings, or professional workloads like 3D rendering and ML inference.
Everything you need to know about processors before you buy.
A CPU (Central Processing Unit) is the brain of your PC — it handles every instruction your software sends, from running the operating system to executing game logic and processing physics. Unlike a GPU which runs thousands of tiny parallel tasks, a CPU excels at running a smaller number of complex, sequential tasks very fast. For gaming, a strong single-core speed matters most; for creative work like video editing or 3D rendering, having more cores significantly reduces processing time.
The number of physical processing units. More cores help with multitasking and parallel workloads, but most games still rely more on single-core speed.
Measured in GHz. Base clock is the default operating speed; boost clock is the maximum speed reached under single-core load. A higher boost clock generally means snappier single-threaded performance, which matters most for gaming.
How many watts the CPU consumes at peak load. Higher-end CPUs (125W+) generate more heat and require a capable cooler — stock coolers are often insufficient. TDP also affects your total system power budget when sizing a PSU.
On-chip memory that stores frequently used data for ultra-fast access. A larger L3 cache reduces latency for gaming workloads. AMD's 3D V-Cache technology dramatically increases cache size and measurably improves gaming frame rates.
The CPU socket must match your motherboard. Sockets are not interchangeable between brands or generations.
CPUs specify which DDR generation they support (DDR4 or DDR5) and the maximum officially supported speed. Running RAM at its rated speed (via XMP/Expo) can noticeably improve performance, especially on AMD Ryzen platforms.
Solid gaming performance, handles most tasks without bottlenecking mid-range GPUs.
Strong gaming and productivity balance. Great for gaming + streaming simultaneously.
For no-compromise gaming, heavy multitasking, video production, or 3D work.
Everything you need to know about motherboards before you buy.
A motherboard is the main circuit board that connects every component in your PC — the CPU, RAM, GPU, storage, and power supply all plug into or communicate through it. It determines which CPUs and RAM are compatible with your build, how many storage drives you can connect, and what expansion options you have. Choosing the right motherboard means matching it to your CPU socket, your use case, and your budget — a more expensive board doesn't always mean better performance, but it does unlock features like overclocking, more USB ports, and better power delivery.
The physical slot the CPU locks into. Socket must exactly match your CPU — there is no cross-compatibility.
Controls which features are available: overclocking support, number of PCIe lanes, USB ports, and M.2 slots. Higher chipsets cost more but unlock more capability.
The physical size of the board — determines what cases it fits in and how many slots it has.
Most ATX boards have 4 DIMM slots; Micro ATX usually 4; Mini ITX typically 2. Check the maximum supported RAM capacity and speeds. Always verify your RAM kit is on the motherboard's QVL (qualified vendor list) for guaranteed compatibility.
M.2 slots are for fast NVMe SSDs. More slots = more high-speed storage. SATA ports connect older SSDs and HDDs. Budget boards may have 1–2 M.2 slots; high-end boards can have 4+. Check whether slots support PCIe Gen 4 or Gen 5 for maximum SSD speed.
The Voltage Regulator Module (VRM) controls power to the CPU. A stronger VRM is essential for overclocking or running high-TDP CPUs. Budget boards with weak VRMs can throttle or overheat under sustained load with powerful processors.
Solid for non-overclocked builds. Enough M.2 slots and USB for most users. Skip if pairing with a high-TDP CPU.
Better VRMs, more M.2 slots, more USB, and usually overclocking support. The right tier for most builds.
Flagship VRMs for extreme overclocking, PCIe 5.0 M.2, premium audio, and extensive connectivity.
Everything you need to know about system memory before you buy.
RAM (Random Access Memory) is your PC's short-term working memory. When you open a game, browser, or application, it loads data from your storage drive into RAM so the CPU can access it instantly — storage is far too slow for real-time use. More RAM means more things can run at once without slowdown; faster RAM means data gets to the CPU more quickly. Unlike storage, RAM is volatile — everything in it is cleared when the PC powers off.
How much data RAM can hold at once. More capacity lets you run more programs simultaneously without the OS swapping to slower storage.
How many data transfers per second the RAM can perform. Faster RAM reduces latency between CPU and memory. AMD Ryzen is especially sensitive to RAM speed — running at the rated speed (via Expo) can noticeably improve gaming FPS.
DDR4 and DDR5 are not interchangeable — the physical slots are different. Your CPU and motherboard dictate which generation you use. DDR5 is faster and the current standard for new platforms, but DDR4 is cheaper and still very capable.
Expressed as numbers like CL16 or CL30. Lower CL numbers mean faster response. Timings and speed work together — a DDR5-6000 CL30 kit can outperform a DDR5-6400 CL36 kit. Don't focus on speed alone.
Using two matched sticks instead of one activates dual-channel mode, effectively doubling the memory bandwidth available to the CPU. This is one of the easiest free performance gains — always use RAM in pairs (e.g., 2×16 GB instead of 1×32 GB).
RAM ships running at a conservative default speed (often 2133–4800 MHz) regardless of its rated speed. XMP (Intel) and Expo (AMD) are BIOS profiles that unlock the rated speed with one toggle. Always enable this after building — it's safe and often free performance.
16 GB DDR4 or entry DDR5. Handles everyday gaming and general use without issue.
32 GB DDR4 or fast 32 GB DDR5. Ideal for gaming + multitasking or light creative work.
64 GB DDR5 or high-speed 32 GB kits with tight timings. For video editing, 3D work, or heavy multitasking.
Everything you need to know about power supplies before you buy.
A Power Supply Unit (PSU) converts AC power from your wall outlet into the stable DC voltages your PC components need to run. Every component in your build — CPU, GPU, storage, fans — draws power through the PSU. Choosing the right one means matching wattage to your system's demands, picking a reliable unit with a good efficiency rating, and leaving enough headroom so the PSU isn't running at its limit. A low-quality or underpowered PSU is one of the most common causes of system crashes, instability, and in extreme cases, component damage.
The total continuous power the PSU can deliver. Add up your CPU TDP + GPU TDP + ~100W for the rest of the system, then add 20–30% headroom.
Measures how efficiently the PSU converts AC to DC. A higher rating wastes less power as heat, runs cooler, and costs less to operate. The rating tiers from lowest to highest:
Determines which cables are permanently attached to the PSU.
Modern PSUs deliver power primarily on a single +12V rail. The 12V rail powers the CPU and GPU — the components with the highest power demand. Check that the PSU's 12V amperage rating matches the combined draw of your CPU and GPU, not just total wattage.
Quality PSUs include hardware protections that cut power before damage occurs:
Most desktop builds use ATX PSUs. Small form factor builds may require SFX or SFX-L units, which are physically smaller but often cost more per watt. Always check your case's PSU size spec before buying.
650W 80+ Bronze or Gold. Reliable for mid-range builds. Stick to known brands — cheap no-name PSUs at this tier are a risk.
750–850W 80+ Gold, fully modular. The right pick for most gaming builds including RTX 4070/4080 tier.
1000W+ 80+ Gold/Platinum, fully modular. Required for RTX 4090 / RX 7900 XTX builds or dual-GPU workstations.
Everything you need to know about CPU cooling before you buy.
A CPU cooler draws heat away from the processor and dissipates it into the surrounding air. CPUs generate significant heat under load — without a cooler, a modern CPU would overheat and shut down within seconds. The cooler sits directly on top of the CPU, connected via a thin layer of thermal paste that fills microscopic gaps and improves heat transfer. A better cooler keeps temperatures lower, which allows the CPU to sustain higher boost clocks for longer, reduces fan noise, and extends the component's lifespan.
Thermal Design Power — the maximum heat load the cooler is rated to handle, in watts. Match or exceed your CPU's TDP rating. For overclocked or high-end CPUs, go higher than the rated TDP to give yourself thermal headroom.
Measured in decibels. Lower is quieter. Most coolers list noise at maximum fan speed — real-world use is often much quieter since fans rarely hit 100% under normal gaming loads. Anything under 35 dBA is considered quiet; under 25 dBA is near-silent.
Air tower coolers can be 150–170mm tall. Check your case's maximum CPU cooler clearance before buying — a cooler that's too tall simply won't fit with the side panel on. Low-profile coolers (under 60mm) are available for compact builds.
Coolers mount via a bracket that must match your CPU socket. Most modern coolers support both Intel (LGA1700, LGA1851) and AMD (AM4, AM5), but always verify before purchasing. AM5 in particular has seen some cooler compatibility issues with older mounting hardware.
Higher RPM moves more air but creates more noise. Good coolers use PWM (Pulse Width Modulation) fans that automatically adjust speed based on CPU temperature — fast when needed, near-silent at idle. Look for PWM support when comparing fans.
For All-in-One liquid coolers, the radiator size determines cooling capacity. Larger radiators have more surface area to dissipate heat.
Solid air coolers for CPUs up to 125W. A major step up from stock coolers with better temperatures and quieter operation.
High-performance air towers or 240mm AIOs. Handles most CPUs including 125W+ chips with excellent thermals.
Flagship dual-tower air coolers or 280/360mm AIOs. For overclocking, 170W+ CPUs, or silent builds.
