The excitement about Nvidia’s new graphics cards, the RTX 5090 and RTX 5080, is increasing. A big concern is their power usage. These powerful GPUs are expected to consume more power than the current models. You may need to upgrade your power supply unit (PSU) to use them.
Reports suggest that the RTX 5090 has a Total Graphics Power (TGP) of about 575W, while the RTX 5080 is around 360W. By comparison, the RTX 4090 has a TGP of 450W, and the RTX 4080 is 320W. This shows a notable increase in power requirements.
Nvidia recommends a 1000W PSU for the RTX 5090 in most systems, depending on your other hardware. If you have a high-end CPU or extra components like multiple storage drives, a 1200W or higher PSU might be best for more capacity. For the RTX 5080, you should use at least an 850W PSU, but a 1000W unit is better for added safety.
To handle these power demands, a good PSU is essential. For the RTX 5090, a 1000W PSU or higher is likely needed. The RTX 5080 will probably work best with an 850W PSU or higher. These are just estimates. The actual needed wattage may change when the cards officially launch.
The RTX 5090 and RTX 5080 utilize the new 12V-2×6 power connector. This connector is specifically designed to meet the higher power demands of next-generation GPUs. It is an updated version of the 12VHPWR connector found on some RTX 40 series cards and can provide up to 600W of power. This ensures that high-performance graphics cards receive the necessary power to operate at their full potential.
It is important to ensure that your power supply unit (PSU) includes this connector or comes with an adapter if you plan to use one of these new GPUs. Using the correct connector is crucial for safe and stable operation.
Besides wattage, PSU efficiency is very important. Look for PSUs with an 80 Plus Gold or Platinum rating. These ratings mean the PSU wastes less power as heat. This is important for powerful GPUs that use a lot of energy. A more efficient PSU saves you money on your power bill and keeps your system cooler.
If you plan to buy an RTX 5090 or RTX 5080, check your current PSU. If it does not meet the recommended wattage, you will need a new one. This adds to the overall cost of upgrading your graphics card.
Reports suggest the RTX 50 series will launch around January 30, 2025. The RTX 5090 may cost around $1,999, and the RTX 5080 may cost around $999. These are projected prices and could change.
The trend toward more powerful graphics cards will likely continue. This means power needs will probably keep going up. When you build a new PC or upgrade an old one, think about future power needs. A good PSU can last for many years and handle multiple upgrades.
Cooling is also crucial, especially with high-power components like the RTX 5090 and 5080. Adequate cooling prevents overheating, which can cause performance drops and even damage hardware. Consider investing in a good CPU cooler and ensure your PC case has good airflow.
Finally, the motherboard you choose should support the features of your chosen CPU and GPU, such as PCIe 5.0 for the fastest data transfer speeds. Check the motherboard specifications to ensure compatibility.
NVIDIA has made headlines with its introduction of the GeForce RTX 50 series graphics cards, setting new standards in power requirements and efficiency for high-end gaming systems. As gamers and content creators plan their ultimate builds, there are pivotal aspects to keep in mind, especially concerning the power supply unit (PSU). For the new RTX 5090 and RTX 5080 GPUs, understanding the necessary wattage and efficiency ratings of PSUs is critical. Gone are the days when a simple plug-and-play was sufficient; now, a high-quality PSU is crucial to unlock the full capabilities of these powerful GPUs.
Power Needs of RTX 5090 and RTX 5080
As noted in announcements, the GeForce RTX 5090 is designed for top-tier performance but comes with an impressive power hunger that cannot be ignored. NVIDIA recommends a system power of at least 1200W to support the RTX 5090, a substantial increase from its predecessor. According to NVIDIA’s specifications, the RTX 5080 requires slightly less power, demanding an 850W system power with a total graphics power of 360W.
Nevertheless, these figures may serve as a baseline. Many users in the community advocate for choosing a PSU with capacities well above the minimum recommendations to accommodate future upgrades, overclocking, or additional peripherals.
“It’s always better to have headroom,” one enthusiast shared, underscoring the importance of a robust PSU for long-term reliability.
When it comes to selecting a suitable PSU for the RTX 5090 and RTX 5080, several prominent features should stand out:
These power supply units come from a variety of manufacturers, with noteworthy products emerging from brands like ASUS, CORSAIR, and EVGA. For those aiming for the absolute peak performance, ASUS’s ROG Thor 1200W Platinum III stands out, featuring innovative components designed for high efficiency and stability during intense gaming sessions.
Before finalizing any decisions, it is advisable to utilize the interactive power calculator provided by various manufacturers. This tool factors in all the components of your build and provides an accurate assessment of wattage needs. Most calculators allow users to input their complete setup, including CPU, GPU, cooling solutions, and additional peripherals, to yield a tailored wattage requirement.
As you consider the right PSU, here are some distinguished units recommended for both GPUs:
Users must remember that the choice of PSU could greatly influence the overall performance and longevity of their gaming rig. Reliability makes a huge difference, and premium PSUs are typically built with high-quality components that ensure consistent power delivery even under heavy loads.
The importance of efficiency cannot be overstated, as a higher efficiency rating (like 80 Plus Gold or Platinum) indicates lower energy wastage, meaning more of the power drawn from your wall socket makes it to your PC components.
“Less heat means a quieter system and better performance over time,” noted a gaming hardware expert, highlighting how effective power delivery positively impacts your experience.
The current crop of ASUS and CORSAIR power supplies ensures an efficiency rating that often exceeds minimum certification requirements—turning roughly 90% of drawn AC power into usable DC power for your build.
Additionally, modern power supplies come equipped with features catering for active cooling and thermal management. By utilizing premium components such as GaN MOSFETs, these power supplies can optimize power delivery while reducing the waste heat generated during operations. This results in a better overall thermal profile for your rig, which can be particularly important during marathon gaming sessions.
For any PC builder, cable management is both an aesthetic and functional concern. Most top-tier PSUs are now modular, allowing users to connect only the cables they need while leaving the rest aside. This significantly reduces cable clutter, improves airflow within the case, and ultimately enhances cooling efficiency. Additionally, the newer models utilize etched cables, made from flexible materials that operate at lower temperatures than standard cables, ensuring safe and efficient routing inside the chassis.
The modular and less bulky cables allow you to lay out your internals in a way that optimizes accessibility and airflow; important for those builds that incorporate liquid cooling or other high-performance needs.
NVIDIA’s introduction of new graphics cards has also transitioned towards the ATX 3.1 standard, which provides improved power delivery capabilities for next-gen GPUs. With features such as the new 12VHPWR connectors, users can expect better efficiency and current handling for powering these robust graphics solutions. It’s anticipated that power supplies supporting the ATX 3.1 standard will pave the way for exciting advancements in power management, with increased stability across the board as demand for power-hungry components grows.
Finally, while it may be tempting to go for lower-end power supplies, the risks associated with underperformance—like system crashes and component damage—make choosing a reputable, high-quality PSU an essential task for anyone serious about their gaming performance. The combination of the right wattage, efficiency, and thoughtful features will ensure your high-end NVIDIA GPUs run at their absolute best.
