The ASUS GeForce RTX 5060 LP BRK is a low-profile card built around the Ada Lovelace successor architecture, with 8GB of GDDR7 memory and a PCIe 5.0 interface. Its compact, dual-slot low-profile design is aimed squarely at slim cases and small form factor builds where space is at a premium.
In terms of power draw, the RTX 5060 sits in a comfortable mid-range bracket. Expect around 115W to 150W at full load under gaming conditions. That's not demanding by any stretch. But here's the thing: your GPU is only one part of the equation. A modern mid-range CPU can pull 65W to 125W on its own, and once you add storage, RAM, cooling, and fans, a complete system can hit 300W to 400W without breaking a sweat.
So what does that mean for PSU selection? A 650W unit is technically sufficient for most RTX 5060 LP BRK builds. But 750W is the sensible starting point because it gives you 20 to 30% headroom above your actual load. PSUs run most efficiently and quietly at around 50% load, so a 750W unit running a 350W system is operating in its sweet spot.
On the connector side, the RTX 5060 LP BRK uses a standard PCIe power connector rather than the high-amperage 16-pin 12V-2x6 connector you see on RTX 4090-class cards. Any PSU from the last five years with a 6+2 pin PCIe cable will connect cleanly. That said, buying an ATX 3.0 or ATX 3.1 compliant PSU is still smart because those standards improve transient spike handling across the board.
For compact builds, fully modular PSUs are the right call. You only plug in what you need, which keeps the inside of a small case tidy and maintains proper airflow around the GPU. Semi-modular works in a pinch, but the fixed cables always seem to end up in the wrong place in tight builds.

Understanding PSU Wattage and Efficiency Ratings
Calculating the right PSU wattage is simpler than most guides make it sound. Add up the TDP of your CPU and GPU, then add roughly 50W to 100W for the rest of your system (storage, RAM, fans, motherboard). Then apply a 20 to 30% headroom buffer on top of that total. So if your CPU pulls 95W and your RTX 5060 LP BRK pulls 150W, your base system load is around 280W. Add 20% headroom and you're looking at 336W. A 650W or 750W PSU is the right size. Simple.
On efficiency ratings, the 80+ programme certifies that a PSU delivers at least 80% of the power it draws from the wall to your components. The rest becomes heat. The tiers work like this:
- 80+ Bronze: 82 to 85% efficiency. Acceptable, but not what you want in 2026.
- 80+ Gold: 87 to 92% efficiency. The sweet spot for most builds. All eight PSUs in this guide hit at least Gold.
- 80+ Platinum: 90 to 94% efficiency. Meaningful savings on electricity bills over years of use.
- 80+ Titanium: 92 to 96% efficiency. The top of the standard programme. Reserved for premium units like the Corsair AX1600i.
Transient power spikes are a separate consideration. Modern GPUs can spike well above their rated TDP for brief moments during scene transitions or shader compilation. ATX 3.0 and ATX 3.1 specifications require PSUs to handle spikes of up to three times the rated GPU power connector capacity without tripping protections. For an RTX 5060 LP BRK, this is less of a concern than for a 4090-class card, but a compliant PSU handles it cleanly regardless.
Common Mistakes to Avoid
- Mistake: Buying a non-modular PSU for a compact or low-profile build.
Instead: Always go fully modular when building in a small case. Fixed cables create clutter that blocks airflow and makes assembly a nightmare. - Mistake: Choosing a PSU based on wattage alone without checking the efficiency rating.
Instead: Aim for 80+ Gold as a minimum. A 750W Gold unit is a better buy than a 1000W Bronze unit for an RTX 5060 system. - Mistake: Ignoring the warranty length when comparing similarly priced PSUs.
Instead: A ten-year warranty versus a five-year warranty is a meaningful difference. PSU failures can take other components with them, so longer coverage matters. - Mistake: Assuming an SFX PSU will fit because the case is small.
Instead: Check whether your case takes SFX or SFX-L specifically. The two sizes are not interchangeable, and buying the wrong one means returning it.
Final Verdict: Best Power Supplies for ASUS GeForce RTX 5060 LP BRK 8GB GDDR7 Graphics Card
After comparing all eight options, the Corsair AX1600i 1600W 80+ Titanium is the best power supply for ASUS GeForce RTX 5060 LP BRK 8GB GDDR7 graphics card if you want the absolute best with no compromises. But most people building around this GPU will be better served by the MSI MAG A750GL for budget builds or the Seasonic Focus V4 GX-850 for a premium mid-range option. SFX builds should look at the ASUS ROG Loki SFX-L 1200W. There's a proper answer here for every scenario.
