Finding the best power supplies for ASUS GeForce RTX 4060 DUAL EVO 8G OC WHITE Gaming Graphics Card 2535MHz Boost Clock GDDR6X PCIe Gen 4 DLSS 3 3x DP v 1.4a HDMI 2.1a is genuinely important. Get it wrong and you risk instability, crashes, or worse. Get it right and your build runs quietly and efficiently for years. This guide covers eight carefully selected PSUs, from a sensible 750W Gold unit all the way up to a 1600W Titanium powerhouse, so you can pick the one that actually fits your build and budget.

Compatibility Guide: Best Power Supplies for Asus Geforce Rtx 4060 Dual Evo 8g Oc White Gaming Graphics Card 2535mhz Boost Clock Gddr6x Pcie Gen 4 Dlss 3 3x Dp V 1 4a Hdmi 2 1a

The ASUS GeForce RTX 4060 DUAL EVO 8G OC WHITE has a rated TDP of 115W, which makes it one of the more power-efficient cards in its class. But that number only tells part of the story. Under gaming loads, GPUs regularly produce transient power spikes that can briefly hit two or even three times the rated TDP for microseconds at a time. A cheap PSU with poor capacitors will struggle with these spikes, causing voltage drops, crashes, or in bad cases, hardware damage.

So what does that mean in practice? For a typical gaming build with a mid-range CPU like a Core i5 or Ryzen 5, 650W to 750W is genuinely enough. Add a high-end CPU like a Core i9 or Ryzen 9, multiple NVMe drives, and case fans, and you are looking at 800W to 850W being a more comfortable target. None of the PSUs in this guide are undersized for the RTX 4060.

On connectors: the RTX 4060 DUAL EVO OC WHITE uses a single 8-pin PCIe power connector. You do not need a 16-pin 12VHPWR cable or PCIe 5.0 compatibility. Any PSU made in the last six or seven years will have the right connector. That said, several PSUs in this guide are ATX 3.0 or ATX 3.1 compliant, which means they handle transient spikes more gracefully. Worth considering if you plan to upgrade to a higher-end GPU later.

Efficiency ratings matter too. 80 Plus Gold means the PSU is at least 87% efficient at 50% load, which is where most gaming builds spend most of their time. Platinum pushes that to 90%, and Titanium to 92% or higher. The difference in electricity cost over a year is modest, but the higher-rated units tend to run cooler and quieter because they generate less waste heat. For a card as efficient as the RTX 4060, Gold is genuinely fine. Platinum and Titanium are nice to have rather than essential.

For more detail on how the RTX 4060 performs in real-world scenarios, TechPowerUp's RTX 4060 GPU database entry is a solid reference. And for ASUS's own product documentation, the ASUS UK product page for the DUAL EVO OC WHITE covers official specs and requirements in full.

Understanding PSU Wattage and Efficiency for the RTX 4060

Here is the thing: choosing a PSU is not just about picking a number bigger than your GPU's TDP and calling it done. There is a bit more to it, and getting it right makes a real difference to system stability and long-term component health.

Start with your GPU's TDP. The RTX 4060 DUAL EVO OC WHITE sits at around 115W under typical gaming loads. Add your CPU. A mid-range chip like a Core i5 or Ryzen 5 pulls around 65W to 125W under load. Add storage, RAM, case fans, and a motherboard, and a typical gaming build is pulling 300W to 450W total. So why do people recommend 650W to 850W PSUs? Two reasons.

First, transient power spikes. GPUs do not draw constant power. They spike hard for milliseconds at a time, sometimes hitting two to three times their rated TDP. A PSU running at 90% of its rated capacity has very little room to absorb these spikes, which causes voltage instability. Running a PSU at 50% to 70% of its rated capacity is the sweet spot for both efficiency and spike tolerance.

Second, efficiency curves. Every PSU has a peak efficiency point, typically around 50% load. An 850W PSU powering a 400W system is running at roughly 47% load, right in the efficiency sweet spot. A 550W PSU powering the same system is at 73% load, still efficient but getting warmer and working harder. The 80 Plus rating tells you the minimum efficiency at 20%, 50%, and 100% load: Gold means 87% at 50%, Platinum means 90%, Titanium means 92%. For the RTX 4060, Gold is genuinely sufficient. Platinum and Titanium are worth it if you run your PC for long hours daily and want lower electricity bills and cooler operation over time.
