you should be fine with a 750w psu. They did the test with an i9–10900k and RTX 3070 and said you should be able to scrape by with a 650w psu but I would recommend going with a 750 gold psu to be safe. Was this worth your time?

The 3080 requires a 750W PSU, while the 3070 only requires 650W.

What PSU do I need for RTX 3070?

NVIDIA recommends a 650W PSU for the RTX 3070, but if you're currently working with, say, a 600W PSU, you might get along just fine depending on other hardware in your system.

Do I need a 650 or 750 watt power supply for 3070?

This is from the Nvidia website: Finally, for the Nvidia GeForce RTX 3070 PSU requirements, you'll "only" need 650W for Core i5/i7 & Ryzen 5/7 systems, 750W for Core i9/Ryzen 9 systems, and 850W for HEDT/Threadripper platforms.

Is a 650W gold PSU enough for an RTX 3070 Ti? For a 3070ti+ you should have atleast a 750w PSU, and if you want room for future upgradability or addons get an 850w PSU. All gold/plat ratings, don't get a bronze.

Is a 750w Power Supply the Bare Minimum For New GPUs?

Is 850W PSU overkill for RTX 3070?

Yes, assuming your PSU isn't incredibly cheap and providing way less power than advertised you should have absolutely no problem running those. Nvidia technically recommends a 650-watt power supply along with the 3070 but that is to cater to massive overclockers and people with power supplies much worse than claimed.

Is 750W enough for RTX 3070 and i9?

Yes. Nvidia recommends 750W psu for it and it exactly what you are asking about .

Does a 750 PSU always use maximum power?

Keep this in mind when considering higher wattage PSUs: a 750-watt power supply does not consume 750 watts by default. If your system is drawing 500 watts, your power supply will supply 500 watts, regardless of maximum capable output.

What happens if your PSU is too weak?

What happens if your Power Supply is too weak for your GPU or PC? Well, best-case scenario, your PC or GPU will just underperform. Most likely, though, it'll crash outright – and worse.

Do I really need a 750 watt power supply?

In conclusion, if you're looking to replace the power supply of a typical branded computer, a 400 watts would be just fine.

What PSU wattage do I need for a GeForce RTX 3070 Ti? The card itself uses up to 290W.

Does 3070 need 2 PSU cables?

Answer: it's a single cable with two 6+2 pin plugs on it. It's recommended to use separate cables for each of the two 8 pin PCI-E power connectors on the card. However, the card is rated for a maximum power draw of 220W.

What power supply do I need for 3070 and 3080?

As such, you'll only need a 650W PSU in your system to keep this card humming along. The 3070 Ti uses the same flow-through cooling solution that we saw in the 3080, 3080 Ti, and 3090, but we'll tackle that in a bit.

Is 750W PSU enough for 3070 and Ryzen 7 5800X?

Assuming it is a decent unit (check PSU tier list on other forums or straight from jonnyguru's content), 750W is plenty. Your main components require about 325 to 400W (5800X is rated for 105W TDP and 3070 220W).

Is 750W enough for RTX 3070 and 5800X?

I agree. I'm using the 750W Nvidia recommendation (Corsair SF750) for a stock 3090 and 5800x w/ PBO and its been flawless. For a 3070, 550-600W is still fine.

What are the signs of not enough PSU?

Random program crashes, system freezes and the Blue Screen of Death are all symptoms of a computer that's not getting enough power. Like with graphical degrades, system instability symptoms often follow adding new hardware or upgrading existing components.

How do I know if my PSU is not enough?

What happens if you underpower a GPU?

What happens when a graphics card is underpowered? I presume you mean electrically underpowered, not weak. A few things can happen but they are mundane. It could just not turn on, it could perform worse than expected or it could become unstable.

Is A 750 watt power supply overkill?

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.

What happens if you buy a too powerful PSU?

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.
