Before you spend a penny, it's worth understanding exactly what the ASUS RTX 3060 DUAL V2 OC actually needs from a power supply. The card has a rated TDP of 170W and draws power through a single 8-pin PCIe connector. Simple enough. But the full picture is a bit more involved.
First, wattage. NVIDIA's own system requirement is 650W, but that figure assumes a relatively modest CPU. Pair the RTX 3060 with a Ryzen 9 7900X or an Intel Core i9-13900K and you're looking at combined peak loads well above 350W. Add case fans, RGB, NVMe drives, and a few USB peripherals, and 650W starts to feel tight. A 750W to 850W unit is the sensible target for most mid-range to high-end builds.
Second, transient spikes. Modern GPUs, including the RTX 30-series, can draw power well above their rated TDP for very brief periods during heavy rendering or load transitions. A PSU with good transient response and solid capacitors handles these without the voltage rail drooping. This is one reason why brand and build quality matter far more than the wattage number alone.
Third, the connector. The ASUS RTX 3060 DUAL V2 OC uses a standard single 8-pin PCIe power connector. Every PSU in this guide provides at least one 8-pin PCIe cable, so there are no compatibility issues on that front. You do not need a 16-pin ATX 3.0 adapter for this card.
Fourth, form factor. All eight PSUs listed here are standard ATX units, which fit the vast majority of mid-tower and full-tower cases. The ASUS ROG Loki is SFX-L format, so if you're building in a compact ITX case, that one deserves a closer look. For standard ATX cases, any of the others will fit without issue.
Finally, efficiency. UK electricity costs make 80 Plus Gold the minimum worth considering. Gold certified units hit 87 to 90% efficiency under load, meaning less wasted energy as heat and lower electricity bills over the lifetime of the build. Platinum and Titanium push that further, which matters if the PC runs for long hours.
As a reference point, Corsair's official PSU range page gives detailed technical specs for each unit, and Tom's Hardware's GPU hierarchy provides independent context on the RTX 3060's position in the current GPU landscape.

Understanding PSU Wattage and Efficiency for the RTX 3060 DUAL V2 OC
Right, let's talk numbers. The ASUS RTX 3060 DUAL V2 OC has a TDP of 170W. But your GPU doesn't run in isolation. Add a modern gaming CPU (anywhere from 65W to 253W depending on your chip and workload), storage drives, case fans, and USB devices, and your total system draw climbs fast.
A rough calculation for a typical mid-range build: 170W GPU plus 125W CPU plus 30W for everything else equals around 325W under full load. A 650W PSU running at 50% load sits in a comfortable efficiency range. But add a power-hungry CPU, push both to 100%, and factor in transient spikes, and 650W starts to feel less comfortable. That's why 750W to 850W is the real sweet spot for the best power supplies for ASUS GeForce RTX 3060 12G DUAL V2 OC gaming graphics card 1867MHz boost clock GDDR6 PCIe Gen 4 DLSS 2 1x DP v1.4a 1 x HDMI 2.1 1 x DVI-D.
On efficiency ratings: 80 Plus is a third-party certification scheme. Bronze means at least 82% efficiency at 20% load and 85% at 50% load. Gold pushes that to 87 to 90%. Platinum hits 90 to 92%. Titanium reaches above 92% and is the highest available. Higher efficiency means less energy wasted as heat, lower electricity bills, and a cooler-running PSU. For a PC that's on for several hours a day, the difference between Bronze and Gold adds up over a year.
Modular cabling is another consideration. Fully modular PSUs let you connect only the cables you need, keeping unused ones out of the case entirely. Semi-modular units have the main 24-pin ATX and CPU cables fixed, with the rest detachable. Non-modular units have all cables permanently attached. For an RTX 3060 build where airflow around the GPU matters, fully modular is the right call.
Common Mistakes to Avoid
- Mistake: Buying the cheapest PSU to save money on a build.
Instead: The PSU powers every component in your system. A dodgy unit can damage your GPU, CPU, and motherboard. Spend properly on a reputable brand with at least 80 Plus Gold certification. - Mistake: Assuming wattage is the only thing that matters.
Instead: Build quality, capacitor grade, voltage regulation, and transient response all affect real-world stability. A quality 750W unit beats a cheap 1000W unit every time. - Mistake: Ignoring modular design and then struggling with cable management.
Instead: Choose a fully modular PSU for an RTX 3060 build. Unused cables stuffed behind the motherboard tray restrict airflow and raise GPU temperatures unnecessarily. - Mistake: Not checking the PSU connector type before buying.
Instead: The RTX 3060 DUAL V2 OC needs a single 8-pin PCIe connector. Verify your chosen PSU includes one. All eight units in this guide do, but it's always worth confirming.
