The ASUS GeForce RTX 5060 LP BRK is a low-profile card built around the Ada Lovelace successor architecture, running 8GB of GDDR7 memory over a PCIe 5.0 interface. Its TDP sits at roughly 150W, which is genuinely modest by modern GPU standards. But that figure alone doesn't tell the whole story when you're choosing a PSU.
Here's the thing: modern GPUs don't draw power smoothly. They spike. Hard. The RTX 5060 can briefly pull two to three times its rated TDP during sudden workload transitions, something that catches older or budget PSUs off guard and causes the system to crash or reboot. This is exactly why ATX 3.0 and ATX 3.1 compliance matters. These standards require PSUs to handle 200% peak power excursions for up to 100 microseconds. It sounds technical, but in practice it means your system stays stable under gaming loads.
For connector compatibility, the RTX 5060 LP BRK uses a standard 8-pin PCIe power connector. You won't need the 16-pin 12VHPWR connector found on higher-end cards. That said, any of the PSUs in this guide will have the right connectors sorted.
Form factor is another consideration specific to this card. The LP BRK designation means it's designed for low-profile cases. Some of those cases only accept SFX or SFX-L PSUs. If that's your situation, the ASUS ROG Loki SFX-L is the obvious pick. For standard ATX cases, you have the full range to choose from.
In terms of wattage, a 750W unit comfortably powers the RTX 5060 LP BRK alongside a modern mid-range CPU like a Ryzen 5 or Core i5. If you're running a more power-hungry CPU (Ryzen 9, Core i9) or plan to add multiple storage drives and fans, step up to 850W or 1000W. The extra cost is small, and the peace of mind is worth it. Always aim for the PSU to run at 50 to 70% of its rated capacity under typical loads. That's where efficiency peaks and thermals stay sensible.
For a deeper technical breakdown of what makes these units tick, TechPowerUp's PSU reviews are an excellent reference. And for the official ASUS product page on this GPU, see the ASUS UK graphics cards page.

Understanding PSU Wattage and Efficiency for Your RTX 5060 Build
Choosing the right PSU wattage isn't complicated once you understand the basics. Start with your GPU's TDP (around 150W for the RTX 5060 LP BRK), then add your CPU's TDP (anywhere from 65W for a modest Ryzen 5 to 170W for a Core i9), then add a flat 50W for motherboard, RAM, storage and fans. That gives you your total system draw. Now double it. That's your ideal PSU wattage target. Why double? Because PSUs run most efficiently at 50% to 70% of their rated capacity, and you want headroom for transient spikes.
So for a typical RTX 5060 build with a Ryzen 5 9600X (65W TDP): 150W + 65W + 50W = 265W total. Double that is 530W. A 650W to 750W PSU is therefore the sensible sweet spot. Going to 850W gives extra breathing room and keeps the unit running cooler and quieter.
On efficiency ratings: the 80 Plus scheme tests PSUs at 20%, 50% and 100% load. Bronze hits 82% to 85% efficiency. Gold reaches 87% to 90%. Platinum hits 90% to 92%. Titanium pushes past 92% and peaks above 94%. The difference in electricity cost between Gold and Titanium over a year of typical gaming is real but modest. For most users, Gold is the right call. Platinum makes sense if you run your PC eight or more hours daily. Titanium is for enthusiasts and professionals who want the absolute best regardless of cost.
One more thing worth knowing: Cybenetics certification (seen on the NZXT C1000 Gold Core) uses a more rigorous real-world testing methodology than 80 Plus. A Cybenetics Platinum rating often means the unit outperforms its 80 Plus Gold badge in actual use. It's a good sign when you see both certifications on the same unit.
Common Mistakes to Avoid
- Buying a non-ATX 3.0 PSU: Older PSUs weren't designed for the transient power spikes of modern GPUs. They can trip protection circuits mid-game and cause crashes.
Instead: Choose any PSU in this guide. All are ATX 3.0 or ATX 3.1 certified. - Choosing a PSU that runs at 90%+ capacity: Running a PSU near its limit increases heat, reduces efficiency and shortens lifespan.
Instead: Target 50 to 70% load under typical use. For most RTX 5060 builds, that means a 750W to 850W unit. - Ignoring form factor for compact builds: Standard ATX PSUs won't fit in SFX or SFX-L cases. Buying the wrong form factor means a return trip.
Instead: Check your case's PSU form factor specification before buying. If it's SFX-L, the ASUS ROG Loki is your option here. - Skipping modular cabling to save a few pounds: Fixed-cable PSUs force you to stuff unused cables into the case, blocking airflow in already tight low-profile builds.
Instead: Every PSU on this list is fully modular. Stick to these and cable management is sorted from the start.
