I’m begging all you high-end GPU enthusiasts out there😭—please don’t ignore your GPU power cables anymore! An RTX 4090 or 5090 that cost over 10,000 yuan could be completely fried by a crappy cable that costs just a few dozen yuan—it’s a lesson learned the hard way…

I’ve compiled the most concise tips to help you avoid these pitfalls—even beginners can understand them. Don’t get ripped off anymore 👇

✅ Don’t pick connectors randomly: Make sure the 12VHPWR connector is plugged in securely! You should hear a “click” to confirm it’s locked in—even a 1–2mm gap can fry the connector. Never use a “splitter” adapter for dual 8-pin or triple 8-pin connectors!

✅ Don’t skimp on cables: Prioritize the power supply’s original modular cables. For third-party custom cables, you must verify the pinout (different brands have different pinouts—plugging them in wrong will fry your card).

✅ Know your wire gauge: High-end graphics cards require 16 AWG pure copper wire; 18 AWG is barely sufficient; skip aluminum-clad copper cables entirely!

✅ Choose the right connectors: Phosphor bronze with gold or tin plating ensures durability. Unplated brass connectors will loosen after just a few insertions and are prone to arcing.

💡 Quick troubleshooting: Open your case right now—are your cables OEM? Are they plugged in securely? Do the connectors get hot to the touch under heavy load?

PCIe (Peripheral Component Interconnect Express) slots on a motherboard are high-speed expansion slots used to connect additional hardware components like graphics cards (GPU), Wi-Fi cards, sound cards, SSD adapters, and capture cards; these slots come in different sizes such as x1, x4, x8, and x16, where larger slots provide more data bandwidth for high-performance devices—modern PCs rely on PCIe slots for faster communication between the motherboard and connected hardware, improving gaming, processing, storage speed, and overall system performance; choosing the right PCIe slot is important because it affects compatibility, speed, airflow, and upgrade flexibility in a computer system.

If you’ve ever tried editing a video and your computer started lagging, freezing, or crashing, the most common reason is insufficient RAM. RAM (Random Access Memory) is one of the most important components for video editing performance, often even more noticeable than the processor or graphics card. It determines how smoothly your editing software runs, how many tasks you can handle at once, and how easily you can work with large video files.

What RAM actually does while editing

RAM is your computer’s short-term working memory. When you open software like Adobe Premiere Pro, Final Cut Pro, or DaVinci Resolve, the program loads important data into RAM so it can access it quickly. This includes:

video clips and images in your timeline

transitions and visual effects

preview files

program background processes

multitasking apps like browsers or audio tools

The more RAM you have, the more data your computer can keep “ready to use” instantly. With too little RAM, your system is forced to use the hard drive as temporary memory, which is much slower — that’s when stutter and crashes begin.

How much RAM do you need?

The right RAM amount depends on what kind of work you do:

8GB RAM – Only for basic, low-resolution editing; expect lag

16GB RAM – Good for 1080p editing and beginner projects

32GB RAM – Ideal for 4K editing and professional workflows

64GB+ RAM – Required for 6K, 8K, RAW footage, or studio projects

Higher video resolution means more data, and more data means more RAM is required.

RAM speed also matters

RAM isn’t only about capacity. Speed (measured in MHz) affects how quickly data moves between RAM and CPU. Faster RAM:

improves timeline responsiveness

speeds up preview playback

helps with multitasking

reduces render and export slowdowns
