I'm wondering if a 750W power supply is enough power for my setup, specifically with a Gigabyte 5070 graphics card. I have a DeepCool Gamerstorm PN750M. Would this be adequate or should I consider a higher wattage?

Make sure to consider all components: CPU, memory, number of drives, and cooler types. If it's just the 5070, then a 750W is adequate, but if you have a more demanding CPU, then consider a bit more wattage.
I have an i7 14700F with 32GB DDR5 and a couple of SSDs, plus an air cooler. I'm thinking of upgrading to a liquid cooler soon.
If you're pairing the 5070 with a high-end CPU like the 14900K or Threadripper, then a 750W power supply might not be enough. But for standard setups, it should work just fine!
I have an i7 14700F; should that setup be okay?
That’s not true though; I had my 3080 running just fine on a 650W PSU for three years. The 5070 uses less power, making your 750W more than sufficient.
750W should be plenty for your i7 setup, but if you want some extra headroom for future upgrades, going with an 850W model is a more conservative and safe bet.
I run a 5070 TI with a 7500X3D and some case fans on my 750W PSU, and I've never experienced any issues. The highest I've seen it pull is under 500W, even during spikes.
An 850W supply is smart. Even though the 5070 doesn't need it, having extra wattage can help if you upgrade to a more demanding GPU later, like a 3080. The price difference is usually small.

Actually, the 5070 will be fine with 750W regardless of those other components.
