What PSU Do You Need for the NVIDIA GeForce RTX 5060?
Manufacturer specifications for NVIDIA GeForce RTX 5060 reference specification list 145W board power and a 550W system PSU recommendation. Our starting capacity class is 550W; select a CPU allowance below to see when that changes.

What matters for this card
NVIDIA lists 145W total graphics power and 550W system power for the RTX 5060, using a Ryzen 9 9950X system. Its family page includes both 8-pin and PCIe Gen 5 cable options, so inspect the exact partner card. The 180W / 600W figures in the adjacent column belong to the RTX 5060 Ti.
Estimate your system load
Estimated component load: 315W · Sizing target: 550W
Suggested capacity class: 550W · Estimated load: 57%
Estimate only: board-power rating + CPU allowance + 75W for supporting components. A 25% buffer is applied before rounding up, with the starting PSU class as a floor. This is not a measured peak, efficiency prediction or transient certification.
Three CPU allowances, with the arithmetic shown
| CPU input | Est. draw | PSU class | Est. load |
|---|---|---|---|
| 95W CPU allowance | 315W | 550W | 57% |
| 140W CPU allowance | 360W | 550W | 65% |
| 230W CPU allowance | 450W | 650W | 69% |
For the 95W example: 145 + 95 + 75 = 315W; multiplying by 1.25 gives 393.75W before the capacity floor and rounding. Load is component draw divided by PSU capacity: 315 ÷ 550 × 100 ≈ 57%. It is not the buffered target divided by capacity.
Can you keep your existing PSU?
An existing 550W supply needs an exact-model check, not an automatic replacement or an automatic pass. Read its continuous 12V rating, required cable count, condition and the GPU vendor’s system guidance. The estimate cannot inspect protection behaviour, cable condition or a motherboard removing CPU power limits.
Reference power connection: 1 × PCIe 8-pin or a ≥300W PCIe Gen 5 cable, depending on the card. Use a manufacturer-approved cable or the supplied adapter exactly as documented; never assume modular PSU cables share a pinout. Read the GPU connector guide.
Two power supply options for the NVIDIA GeForce RTX 5060
Load figures assume this card using a 145W board-power allowance alongside a 95W CPU allowance and 75W for the rest of the system, giving an estimated DC component load of 315W (not a measured wall draw). Reference connection: 1 × PCIe 8-pin or a ≥300W PCIe Gen 5 cable, depending on the card. Confirm the exact card before choosing cables.
Balanced
Best fitCorsair CX550 (2023) 550W 80+ Bronze
550W · 80+ Bronze
Non-modular but compact at 125 mm, with one dual 6+2 PCIe cable. The honest floor for a single mid-range card on a tight budget.

Corsair CX650 (2023) 650W 80+ Bronze
650W · 80+ Bronze
The small step up from the CX550 for a build that will take a hotter CPU. Same 125 mm body, same non-modular caveat.
Check the CX650 on AmazonThe CX550 is the starting option because it meets the page's capacity and connector filters. This is not a measured efficiency, noise or reliability ranking. Verify the exact model and its included cables. Specifications are taken from each manufacturer's product page; confirm the exact revision before ordering, as connector counts change between refreshes of the same model name.

Sources and limitations
Official specification for NVIDIA GeForce RTX 5060 reference specification. Board power and system recommendation checked September 12, 2026. These are vendor reference figures; factory power limits and connectors can differ on partner models.
A wattage class does not measure PSU quality or guarantee quiet operation. Efficiency, fan control and power-excursion response depend on the exact unit and operating conditions. See the worked PSU headroom guide or enter your components in the full PSU calculator.
Frequently asked questions
Is 145W the whole PC’s power consumption?
No. It is the GPU board-power allowance used on this page. The 95W CPU example totals 315W after adding 75W for the rest of the system. Wall power also includes PSU conversion losses; this calculation does not model them.
Does choosing 550W guarantee enough headroom?
No. Compare the actual CPU limit, card variant and peripherals. In our 230W CPU example, the capacity class is 650W at an estimated 69% load. Changes to power limits or hardware can change the result.
Where should I check fit and cables?
Start with the manufacturer manuals, then use the PC compatibility checker for supported parts and the SFF clearance checker for dimensions. A family-level power estimate does not verify an exact physical build.
