The use of a cutting-edge PFC circuit in combination with a fully digital platform seems to be the key for record-setting performance. Besides its super efficiency, the AX1600i also offers great load regulation, amazing transient response, a long hold-up time, and unparalleled ripple suppression. Moreover, the great benchmark results are accompanied by quiet operation, enabled by a relaxed fan profile and a high-quality FDB fan. Using the Corsair Link software, you're able to choose between three fan modes: performance, balanced, and quiet. An ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature
It's worth noting here that the SF850L does not feature the side-mounted connectors of the RMx SHIFT PSUs. That being said, it doesn't matter much as small form-factor cases don't allow for such features anyway. Let's look at the specs for this one. Consider upcoming GPU power requirements. Although the best graphics cards are usually more power-efficient than previous generations, their power consumption increases overall. This is why the latest 12+4 pin connector that the upcoming generation graphics cards will use will provide up to 600 W of power. Currently, a pair of PCIe 6+2 pin connectors on dedicated cables are officially rated for up to 300W, and three of these connectors can deliver up to 450W safely. You should also add the up to 75W that the PCIe slot can provide in these numbers.

The Corsair AX1600i is the best PSU that money can buy today, period. It offers top performance in all areas and uses an innovative platform, which provides a glimpse at the future of power supply design.
A dedicated single +12V rail offers simple configuration and maximum compatibility with the latest graphics cards and other components
Yes, you can be safe knowing that as long as it's got 750W of power capacity, it'll be good for an RTX 4080, however, it's always nice to know more just in case, so here's the power table and cable configuration for the CORSAIR RM750x SHIFT.
Great Deal
