The RM750x achieves 80 PLUS Gold and ETA-A efficiency. Cybenetics also gives it a LAMBDA-A+ certification. A roughly 15 dB(A) overall noise output makes the RM750x one of the quietest 750W PSUs available. Although Seasonic's Focus Plus Gold and EVGA's 750 G3 are strong competitors, neither of them are as quiet. 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.

A dedicated single +12V rail offers simple configuration and maximum compatibility with the latest graphics cards and other components Complies with the European Union ErP Directive (2009/125/EC) so the power consumption of the whole system, in either standby or off mode, can be less than 1W when used with a properly configured, ErP-compliant motherboard 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. This is probably what Corsair determined as well through wear testing, decided that not only would that reduce their warranty fulfillment costs but also improve customer satisfaction by having a longer lasting product.DC-DC Converters: 2x UBIQQM3054M6 (30V, 61A @ 100°C, Rds(on): 4.8mOhm) & 2x UBIQ QN3107M6N (30V, 70A @ 100°C, Rds(on): 2.6mOhm) A five year warranty and lifetime access to Corsair's legendary technical support and customer service Besides, it's all a bit silly. If your system is pulling that many amps it's going to need its own more audible fans running anyway. For good lifespan. An internal, reward-facing exhaust, oriented fan is the least audible way to pull or push air through a system. Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components

Electrolytic: 7x Nippon Chemi-Con (1-5,000h @ 105°C, KZE), 7x Nippon Chemi-Con (4-10,000h @ 105°C, KY), 1x Rubycon (4-10,000h @ @ 105°C, YXJ) This would be the perfect Gold PSU if they would have implemented the same fan curve as the older 2018 revision.Disagree. It's still very quiet and I'd rather a tiny noise increase to reduce temps, increase lifespan.
