If you’ve ever shopped for a power supply unit (PSU), you’ve probably seen bold numbers like 650W, 750W, or even 1250W slapped across the box. But here’s a hard truth — not all wattages are created equal.

In this post, we’ll dive into some critical things to check — especially the 12V rail, where most of your system’s power actually goes — and expose how some budget PSU brands overpromise and underdeliver.

Now let’s level up and talk about fine print specs that can make or break your build.

1. Don’t Trust the “Wattage” at Face Value

That big number on the box (e.g. 750W) often refers to the total peak wattage, not continuous wattage. But what really matters is how much power the PSU can reliably deliver on the 12V rail — the rail responsible for powering your CPU, GPU, and other high-draw components.

A cheap “500W” PSU might only provide 360W on the 12V rail, with the rest split between 3.3V and 5V (which modern systems barely use). That’s not enough for a gaming PC with a modern GPU.

2. Always Check the PSU Label (or Official Spec Sheet)

Flip the PSU or check the official website for the detailed rail breakdown, especially the +12V rail rating. A good-quality 650W PSU should provide at least 90% of its rated wattage on the 12V rail (e.g. around 600–630W on +12V).

✅ Good sign: High amperage and wattage on +12V rail

🚫 Red flag: If +12V wattage is much lower than total PSU wattage

3. Look for Independent Testing (Optional but Powerful)

While not every user will do this, some PSU reviewers (like JonnyGURU, TechPowerUp, or Aris from Cybenetics) conduct in-depth testing and even cross-check rail performance under load. Check their reviews if you're buying from lesser-known brands.

4. Single vs Multi +12V Rails: What’s Better?

Most gamers and users are fine with single-rail designs, as long as they come from reputable brands.

5. Beware of Fake 80+ Badges and No-Name PSUs

Some budget brands fake 80+ logos or show specs that don’t match real performance. Unless it's certified by Plug Load Solutions or Cybenetics, take it with a grain of salt.

Your PSU might be the least flashy component, but it’s the lifeline of your entire system. Make sure you're not being misled by flashy numbers — always read the label, check the +12V rail, and when in doubt, go with a reputable brand.

4. Single vs Multi +12V Rails: What’s Better?





Single-rail designs are common today and generally easier to work with.



Multi-rail PSUs offer overcurrent protection per rail, but can sometimes lead to power distribution issues if not well documented.

Most gamers and users are fine with single-rail designs, as long as they come from reputable brands.



5. Beware of Fake 80+ Badges and No-Name PSUs







Some budget brands fake 80+ logos or show specs that don’t match real performance. Unless it's certified by Plug Load Solutions or Cybenetics, take it with a grain of salt.

Avoid PSUs with:





No brand or OEM info



Unrealistically high wattage for dirt cheap prices



Lightweight or suspiciously small housings

Case fans play a critical role in keeping your PC running cool and stable. When they malfunction—whether it’s strange noises, erratic spinning, or not spinning at all—it can lead to overheating, performance drops, or even hardware failure.



In this guide, we’ll walk you through common case fan problems and how to fix them step by step, ensuring your system runs smoothly and quietly.







Common Reasons for PC fans not spinning





Dust buildup: Over time, dust and debris can accumulate on fan blades and bearings, leading to reduced performance or complete failure.



Power issues: Loose cables, faulty connections, or inadequate power supply can prevent fans from operating properly.



Physical Interference: Inadequate cable management might cause the fan blades hitting the cables and lead to slow downs or immobilization.



Faulty motors: Fan motors can degrade with use, eventually failing to spin at all.



BIOS misconfiguration: Incorrect settings in the BIOS may disable the fan or restrict its speed.



Software issues: Malfunctions in fan control software can cause the fan to behave erratically or stop working.



Identifying and Resolving Fan Issues

1. The Fan Isn’t Spinning





⚠️ Common Causes:





Insufficient power due to daisy-chain wiring



Improper cable splicing or loose connections



Malfunctioning fan hub or controller



Fan blades hitting loose cables

👉 How to Fix:





Power down your PC and unplug it from the wall



Open your case and check the fan connections—ensure the fan cable is securely plugged into the correct motherboard header or fan hub.



Try connecting the 4-pin fan directly to another motherboard header to isolate the issue.



You can also test the fan individually by unplugging it from the hub or series connection and powering it separately.

If the fan still doesn’t spin, the fan itself may be defective and should be replaced.



2. The Fan Is Noisy or Makes Strange Sounds





⚠️ Common Causes:





Dust buildup in the bearings or blades



Fan blades hitting loose cables



Vibration-induced resonance between the fan and case

👉 How to Fix:





Turn off your PC and inspect the fan closely.



Clean the blades and bearings using compressed air, a soft brush or alcohol wipes to remove any dust.



Ensure no cables are interfering with the blades.



Check for any physical damage like bent blades or worn mounts.



Test the fan in another system or on an open bench to rule out case vibration as the cause.



If the fan still makes strange noises, the fan itself may be defective and should be replaced



3. The Fan’s RGB Lighting Isn’t Working





⚠️ Common Causes:





Outdated or missing RGB firmware/software



Inadequate power supply



Improper RGB header connection

👉 How to Fix:





Connect the fan’s RGB (3-pin or proprietary) cable to a different RGB header on your motherboard or controller.



Ensure your motherboard lighting software is installed and updated (e.g., ASUS Aura Sync, MSI Center, GIGABYTE RGB Fusion).



If the issue persists, consider using a powered RGB hub to supply sufficient power to the lighting.



As a last check, test the fan’s lighting functionality outside your current build to confirm if it’s a hardware issue.



4. The Fan Spins Too Slowly





⚠️ Common Causes:





Fan speed settings configured to low via BIOS or software



Fan blades hitting loose cables causing slow downs



Internal temperature not high enough to trigger higher fan speed

👉 How to Fix:





Check if the cable is interfering with the fan blades.



Boot into BIOS or open your motherboard’s fan control software.



Adjust the fan curve to increase speeds earlier or set a custom performance profile.

Keep in mind that fans often spin slowly at low system temperatures—that’s completely normal for smart fan profiles.

If the fan still spins abnormally, the fan itself may be defective and should be replaced.



Final Thoughts

A malfunctioning case fan doesn’t just make noise—it can compromise your whole system’s cooling efficiency. Thankfully, most fan issues are easy to identify and fix with a little inspection and testing.

Visualize Your PC Build in 3D — No More Guesswork

While many modern games come with built-in benchmarks to help you instantly assess whether your system runs the game smoothly or if settings are too high or too low, not everyone buys a PC just for gaming. For productivity or professional use, third-party benchmarking tools are a better way to measure your system's performance through detailed data.

Developed by Maxon, Cinebench R23 is a free CPU benchmarking tool that evaluates both single-core and multi-core performance using the Cinema 4D rendering engine to simulate real 3D scene rendering. It’s one of the most widely used benchmarking standards in the industry and among DIY enthusiasts. Bonus: It also supports macOS!

Created by CPUID, CPU-Z is a popular tool for viewing detailed hardware information. It also includes a built-in benchmark module that tests both single-core and multi-core performance using compute-heavy tasks. Unlike Cinebench, it doesn’t simulate real-world scenarios but provides quick and simple performance data.

3DMark is a professional-grade benchmarking tool for testing GPU and overall system performance. It can simulate gaming scenarios, heavy graphics rendering, ray tracing, and more—providing a performance score based on your hardware.In addition to GPU tests (like ray tracing and DirectX 12), it can also evaluate CPU performance. 3DMark is an all-in-one solution, but it comes with a price tag.

FurMark is a stress-testing tool specifically for GPUs. It pushes your graphics card to its limits with a highly demanding "furry donut" rendering, helping you test stability, temperature, and cooling efficiency. This type of testing is often referred to as a “burn-in test.” Thanks to its signature rotating donut graphics, FurMark is jokingly nicknamed "the donut test."

Recommended Software for Testing CPU and GPU Performance

Your PC works hard—whether it’s powering through work tasks, running games, or keeping you connected. But while we rely on our computers every day, cleaning and maintaining them is often overlooked. 

One of the biggest hidden threats? Dust. It builds up over time and can seriously impact performance and even damage your hardware. Let’s break down why regular cleaning is important, how often you should do it, and the best way to safely clean your PC.

Dust might not seem like a big deal, but inside your PC, it’s a different story. Dust buildup can block airflow, causing your system to overheat. When that happens, your CPU and GPU may throttle their performance to stay safe—meaning slower speeds for you. In extreme cases, it can even damage parts permanently.

Performance Drops, Hardware Risk, and a Shorter Lifespan

When fans and vents get clogged with dust, cooling becomes much less efficient. That means higher temperatures, louder fan noise, and increased wear on components. Plus, dust on the motherboard, graphics card, or RAM can lead to static discharge, corrosion, or even short circuits.

Shut down your PC and switch off the power supply. Unplug everything before you open the case.

Most cases have dust filters on the front, top, or bottom. These are easy to remove—some slide out, others are magnetic. You can rinse them with water or wipe them with a damp cloth. Just make sure they’re completely dry before reinstalling.

Remove the side panel carefully. With your compressed air can held upright, blow short bursts of air to clear dust from top to bottom. Focus on fans, heat sinks, and vents.

Use a soft brush to get stubborn dust off fan blades and heatsinks. It helps to hold the fan blades in place while using compressed air so they don’t spin wildly.

5. Be Gentle with the Motherboard and RAM

These parts are delicate. Use short bursts of air only—don’t brush them directly.

A microfiber cloth is perfect for wiping your hard drives, SSDs, and any other visible areas. Use compressed air to clean the PSU vents too.

It depends on your environment and how heavily you use your computer, but here are some general guidelines:

Keeping your PC clean isn’t just about looks—it makes a real difference:

Remove the side panel carefully. With your compressed air can held upright, blow short bursts of air to clear dust from top to bottom. Focus on fans, heat sinks, and vents.



4. Use Brushes and Cloths

Use a soft brush to get stubborn dust off fan blades and heatsinks. It helps to hold the fan blades in place while using compressed air so they don’t spin wildly.



5. Be Gentle with the Motherboard and RAM

These parts are delicate. Use short bursts of air only—don’t brush them directly.



6. Wipe Down Other Parts

A microfiber cloth is perfect for wiping your hard drives, SSDs, and any other visible areas. Use compressed air to clean the PSU vents too.

How Often Should You Clean Your PC?

It depends on your environment and how heavily you use your computer, but here are some general guidelines:







Every 3 to 6 Months is a good rule of thumb for most users.



If you have pets, smoke indoors, or live in a dusty area, aim for every 2 to 3 months.



If you’re a heavy gamer or use your PC for demanding tasks, clean it more often due to higher heat output.



For light users in clean environments, cleaning twice a year is usually fine.







Why It’s Worth It

Keeping your PC clean isn’t just about looks—it makes a real difference:





Better Performance – Lower temps mean your system can run faster and more efficiently.



Longer Lifespan – Less heat and dust stress mean your parts will last longer.



Quieter Operation – Clean fans don’t have to work as hard, which cuts down on noise.

A little maintenance goes a long way toward keeping your system running smoothly, quietly, and for years to come.

Keeping Your PC Clean: How and When to Do It

When using the latest ATX 3.1 power supply, the most important thing to be aware of is the 12V 2x6 connector used for GPU power cables. Although this revised connector has significantly reduced the risk of connector burnouts, improper handling can still cause damage. Please pay special attention to the following points:

Connection Status Between Power Cable and GPU Connector

When connecting the GPU, ensure the direction of the cable and GPU connector matches. Also, confirm that the latch is fully engaged and locked in place.

Avoid Bending the Cable Within 35mm of the Connector

Whether installing the GPU horizontally or vertically, you'll likely need to bend the power cable. If the cable is bent too close to the connector, it can cause the plastic sheath near the connector to peel off, potentially leading to short circuits. It is recommended to bend the cable only after at least 35mm of straight length from the connector.

Do Not Force or Repeatedly Bend the Cable

While modern power cables are built to be durable, excessive force or repeated bending can still damage them, increasing the risk of electrical issues.
