A power supply unit, while seemingly a straightforward component, possesses various attributes demanding attention. Beyond mere wattage, the PSU’s efficiency, often denoted by its 80 PLUS rating, signifies how effectively it converts power from the wall outlet to your system, with Platinum and Titanium being the top tiers.

For a GPU as powerful as the RTX 3080, a higher efficiency PSU can be advantageous, not only for power consumption but also for ensuring stable performance. 

Furthermore, consider the PSU’s modular nature. Fully modular PSUs provide the advantage of connecting only the necessary cables, leading to a cleaner setup and potentially better airflow inside the chassis. Chek out some other options for the best PSUs for RTX 3080 too.

1000W is too much for an RTX 3080. Nvidia recommends a 750W PSU for the founder’s edition. If you want to be on the safe side, especially considering other system components and potential future upgrades, an 850W unit is ample.

Is 750W enough for RTX 3080?

Yes, 750W is what Nvidia recommends for this GPU. However, if you’re looking to ensure optimal power, especially when considering partner GPUs and overclocking endeavors, stepping up to an 850W unit would be a prudent decision.
