The Gigabyte GV-N3060GAMING OC-8GD is based on the Nvidia Ampere architecture and has a TDP of around 170W, with the factory overclock pushing it a touch higher under sustained load. Nvidia officially recommends a 650W system PSU, but that figure assumes a fairly modest CPU. In practice, pair this card with a modern 12-core or 16-core processor and you'll want more breathing room.
On the connector side, things are simple. The RTX 3060 Gaming OC V2 uses a single 8-pin PCIe power connector. No 12VHPWR adapter, no dual 8-pin setup. Any PSU with a standard 6+2 pin PCIe cable will connect cleanly. All eight PSUs in this guide include at least one PCIe cable, so you are covered on that front regardless of which you choose.
For form factor, every unit here is standard ATX, except the ASUS ROG Loki which is SFX-L. Check your case specifications before ordering that one. Standard ATX PSUs measure 150mm wide by 86mm tall, with depth varying from around 140mm on compact units to 200mm on higher-wattage models. Most mid-tower cases handle up to 180mm without issue, but check the PSU clearance in your specific chassis.
On wattage, here is a practical breakdown. A typical RTX 3060 Gaming OC V2 build with a mid-range CPU like a Ryzen 5 7600X or Core i5-13600K will draw around 350W to 400W under gaming load. A 650W PSU covers that, but runs at over 60% load, which is fine. A 750W unit brings that load down to around 50 to 55%, which sits right in the efficiency sweet spot for Gold-rated units. If you are running a high-end CPU, adding NVMe drives, RGB fans, and other peripherals, 850W is the sensible ceiling for this card.
All eight PSUs in this guide are verified compatible with the GV-N3060GAMING OC-8GD. The card connects via PCI-E 4.0 x16 on the motherboard side, and the PSU connects to the card directly via the 8-pin power cable. No special PCIe slot power considerations apply here.

Understanding PSU Wattage and Efficiency for Your RTX 3060 Build
Here's the thing: PSU wattage and efficiency ratings are two separate concepts that both matter, and confusing them is one of the most common mistakes builders make.
Wattage is simply the maximum power the PSU can deliver. Your system draws what it needs, not what the PSU is rated for. A 1000W PSU in a 350W system just runs at 35% load, which is fine but not ideal for efficiency. The sweet spot for most Gold-rated PSUs is 40% to 70% load, where they operate closest to their rated efficiency.
Efficiency ratings tell you how much of the power drawn from the wall actually reaches your components. An 80 Plus Gold unit at 50% load converts at least 87% of incoming power into usable DC power. The rest becomes heat. Platinum gets you to 90%, and Titanium reaches 94%. Over a year of gaming, the difference between Gold and Titanium in electricity costs is modest, but the higher efficiency tiers generally indicate better components throughout.
For the RTX 3060 Gaming OC V2 specifically, independent benchmarks from TechPowerUp's GPU database confirm the card's TDP sits around 170W. Add a mid-range CPU at 65W to 125W TDP, storage, fans, and RGB, and a realistic full-system load is 300W to 450W. That puts a 750W PSU at a comfortable 40% to 60% load under gaming conditions.
Transient spikes are brief, sudden power demands that can exceed the average load significantly. Modern ATX 3.1 PSUs are designed to handle these without voltage drooping. All the ATX 3.1 units in this guide handle transients properly. Corsair's own PSU product pages go into detail on how their digital control systems manage transient response, which is one reason the AX1600i earns its Best Overall badge.
Common Mistakes to Avoid
- Mistake: Choosing a PSU based purely on wattage without checking efficiency rating.
Instead: Look for at least 80 Plus Gold. Platinum and above is better for high-load or always-on systems. - Mistake: Buying a non-modular PSU to save a few pounds, then struggling with cable management.
Instead: All eight PSUs in this guide are fully modular. The cable management benefit is real, especially in smaller cases. - Mistake: Under-specifying wattage to save money, then running the PSU at 80% to 90% load constantly.
Instead: For an RTX 3060 Gaming OC V2 build, 750W to 850W gives you the efficiency sweet spot and comfortable headroom. - Mistake: Assuming a cheap no-name PSU will do the job because the wattage number looks right.
Instead: Stick to reputable brands with proper certifications. A dodgy PSU can damage every component in your system if it fails badly. - Mistake: Buying an SFX-L PSU for a standard ATX case, or vice versa.
Instead: Check your case's PSU specification before ordering. The ASUS ROG Loki in this guide is SFX-L only.
