While NVIDIA recommends a 750W PSU for the RTX 3080, it tested a system with a 10th Gen Intel Core i9-10900K processor (CPU). That's a rather hefty CPU with a TDP of 125W, so depending on your personal system setup, you might be able to get away with something like 650W, especially if the PSU is new.

Is A 1000 watt power supply overkill?

Is 1000 watts too much? 1000W is for SLI builds. But if you are using a RTX 3080 or a 3090, then yes, 1000W is a safe point. It is overkill for 2000 series NVIDIA cards on single, or if you have a lot of ram sticks(8), tons of SSDs and HDDs (4+4) on a big Z motherboard.

Is it bad to have a high wattage power supply?

There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout. The power supply will only provide the needed wattage. For example, a device that needs 50 watts will only get 50 watts from a 250 watt supply, not the entire 250 watts.

Is 750W good for gaming?

750W is the recommended spec but I would go higher if you plan to overclock and upgrade other power hungry parts in the future.

How much RAM do I really need?

Is A 750 watt power supply overkill?

This helps us sort answers on the page. It is overrated because your PSU efficiency is highest at 50% load and 330W is presumably the peak load, so a 650W PSU would be a better match. 750W is close enough to still run efficiently though and it gives you a bit of wiggle room for upgrades.

How big should your power supply be?

A modern power supply must output at least 18A (amps) on the +12V rail(s) for a mainstream up-to-date computer, more than 24A for a system with a single enthusiast-class graphics card, and no less than 34A when it comes to a high-end SLI/CrossFire system.

Is 500W enough for RTX 3060?

Nvidia recommends a 550W PSU as minimum for the RTX 3060. A 500W model might be enough, but you might also see occasional shutdowns if the power use spikes on both CPU and GPU to above 500W. I would buy a 650W PSU for those components just to be sure.

How long will a 1000W UPS power a PC for?

A 1000VA UPS might be able to power a small office computer for around seven minutes. Make the upgrade to a 10kVA UPS, and you might see this figure jump up to around twenty-sevenminutes. Go too small, on the other hand, and the available time shrinks to just a few minutes or less.
