If your gaming rig’s starting to hiccup, crash, or struggle to handle those glorious triple-A titles, the issue might not be your graphics card or RAM—it could be your power supply unit (PSU). Often overlooked, your PSU is the backbone of a stable, high-performance gaming PC. And here at Lithgeek Custom Gaming Computers, right in the heart of 85 Main Street, Lithgow, we know exactly how crucial a solid PSU is when it comes to building or upgrading your dream gaming setup.


💥 Why Your Power Supply Deserves More Respect

Imagine this: You’ve spent $1,200+ on a shiny new GPU, maybe a Ryzen 9 CPU, and a few RGB fans for flair. But the whole thing’s being powered by a no-name, 500W power supply you got in a budget case bundle two years ago. That’s a recipe for disaster.

Here’s what a good PSU brings to the table:

  • Consistent power delivery under high loads (think Cyberpunk 2077 at max settings)
  • Protection for your components from power surges and brownouts
  • Headroom for future upgrades, including higher wattage GPUs and more RGB than a dance floor
  • Improved thermals and airflow with modular cable setups

🔧 PSU Wattage: How Much Do You Really Need?

While 500W might be fine for an office PC, most modern gaming builds need at least 650W to 850W, especially if you’re packing an RTX 4070 or higher. Overclocking? Add another 100-150W buffer. Here’s a quick wattage guide based on common builds:

RTX 3060 Tii5-12400F650W
RTX 4070 TiRyzen 7 7700X750W+
RTX 4090i9-14900K1000W+ (Gold-rated)

At Lithgeek, we carry trusted PSU brands like Corsair, EVGA, and Seasonic, all available on our online store.


⚙️ Modular vs. Non-Modular vs. Semi-Modular

  • Modular: Best for clean builds. Plug in only the cables you need.
  • Semi-Modular: Some cables (like the 24-pin) are fixed, others detachable.
  • Non-Modular: Cheapest, but messier and harder to manage airflow.

Modular PSUs are a dream when paired with custom PC case mods—like our local fave: the cyberpunk case mod with RGB strips and sleeved cables.


🎮 Three Games That Demand PSU Power (And Why)

  1. Cyberpunk 2077 – Ultra settings with RT Overdrive Mode can spike your GPU to max draw.
    • Recommended Specs: RTX 3080, 750W PSU minimum
  2. Starfield – CPU and GPU-intensive, especially with large modded installs.
    • Recommended Specs: RTX 4070, Ryzen 7, 800W PSU
  3. Escape from Tarkov – Complex real-time environments can cause unstable power draw during firefights.
    • Recommended Specs: i7, RTX 3070, 700W PSU
