The RTX 3090 Ti is one of Nvidia’s most power-hungry graphics cards ever created, but that doesn’t mean you need a massive power supply to run it. In fact, a standard 750W unit should be sufficient if you’re building an HTPC or gaming PC. But it’s important to ensure your PSU is high-quality and capable of providing adequate power to the GPU as well as other components in your system. You don’t want to fry your pricey new GPU because of a cheap or low-quality PSU.
Recommended psu for 3090 ti
The Corsair SF750 is a compact, true SFX PSU that offers excellent electrical performance. It’s the best SFX PSU for RTX-3090 Ti systems, as it delivers great transient response and ripple suppression. In addition, it has superb load regulation. In Tom’s Hardware’s extreme 120%, 160%, and 180% load tests, the RM850x only exhibits a minor deviation of 1.09% on its 12-volt rail.
Another great option is the EVGA SuperNOVA 1000 GTR, which provides 1,000 watts of power and has a Gold rating instead of Platinum. If you’re looking for a budget-friendly option, try the Thermaltake Smart BX1 RGB 750W. It’s a semi-modular PSU with a 80 Plus Gold certification. In terms of efficiency, it’s not as good as the EVGA SuperNOVA 1000 GTR, but it should be sufficient for most RTX-3090 Ti systems. In addition, it comes with a nice cable management kit.
