Which PSU Should I Buy For RTX 4070 Ti In 2023?
We know many gamers who love building and keep upgrading their gaming PC mostly get confused about choosing the perfect PSU for their build. The PSU should be not an overkill PSU, an overkill PSU means that if you are having a small build or a less power-hungry GPU and you installed a 1200Wattage or higher PSU then it will be overkill for the build which totally don’t worth buying. The PSU should also not be very low wattage which doesn’t comply with your build total wattage requirement.
There is an easy method to calculate your build total power usage and we have given the example below in the table form. You can make the same calculation by searching your build components specifications online and then calculating all the TDPs which will lead you to the total build power usage, then you can buy a PSU according to that.

1. EVGA 220-G5-0750-X1 Super Nova 750 G5, 80 Plus Gold 750W
EVGA 220-G5-0750-X1 Super Nova 750 G5 Review:
EVGA Super Nova 750 G5 is the PSU that I will recommend for any build with the requirement of 750 watts because this PSU is one of the best-rated 750 Watts PSUs in the year 2023.
As everyone wants to give their builds enough power and stability that does not cause any problems in the future while gaming or heavy workloads that are why better is to choose a PSU wisely and that’s why we choose this PSU for NVidia RTX 4070 Ti because the power requirement is just little below 750Watts even if you are running it on the latest Intel’s Core i9-13900K (Raptor Lake) CPU and the power usage of the complete build is already uploaded above, make sure you read that and compare it with your build.
Best PSU at 750W:
This PSU is best for single GPU builds, but if you are planning for multiple GPUs then I will not recommend any of the 750Watts PSU because the power requirement for that will be above 900 Watts, also this PSU is not recommended for NVidia RTX 4090 and RTX 4080 GPUs because their power draw is higher than NVidia RTX 4070 Ti, thus this PSU will not be having enough watts to run that GPU with any compatible build.
Very Good Value For The Money:
The best thing about this PSU is the price and performance ratio, it has a good price of only $129 right now at amazon, which is very much worth it for its insanely fast performance. The stability of the GPU is also very much impressive under a high workload and also at a minimum workload.
The holdup time for EVGA supernova is too long which won’t bother anyone. The best thing about this PSU is that it will directly improve the power delivery to all the components on the motherboards, and it has almost all the necessary connectors and cables so you can have your RGB and coolers done.
If you want a PSU with a higher wattage than 750 then I will recommend going for the second PSU we recommended and that’s an 850 Watt PSU which is capable of running anything either an RTX 4070 Ti or RTX 4090.
If we talk about the build quality of this PSU then at this price range there is no other PSU more reliable than this one because this PSU is made up of 100% premium material, the capacitors are aluminum made, and are pure Japanese electrolytic capacitors which can bear a temperature upto 105 degree easily, thus meaning that this PSU has the lowest risk of getting dead and it can simple runs for a year without any problem. This PSU is the best option for long gaming sessions because that will not affect the life span of this PSU and also the performance will be stable all the time.
Cons: High Vampire Power:
There are some cons of this PSU that I will mention and explain to everyone, the first major one is the high vampire power of this PSU, vampire power is actually the standard power usage of the PSU when the PSU is not in use and it consumes power or electricity that the vampire power usage, so this PSU sometimes has a vampire power of 0.25W and above with 230V input which is not efficient as it should be.
One more con of this PSU is the fan speed and its noise, when the PSU comes under heavy load or the components on the PC require more power then the PSU goes to peak performance level, and there the fan speed increases with a high level of noise, which the EVGA should have improved.

3. Thermaltake Toughpower Grand RGB 850W 80+ Gold Fully Modular PSU
Thermaltake Toughpower Grand RGB 850W Review:
This Thermaltake Toughpower Grand RGB 850W PSU is best for those who are not satisfied with the 750W PSU which we recommended above the best 750W “EVGA Super Nova G5” PSU, maybe many people like high wattages PSUs for their builds or some maybe will be planning to upgrade from their current NVidia RTX 4070 Ti or any other mid-range GPU to the latest top-tier NVidia RTX 4090 GPU which requires a higher watt PSU like this “Thermaltake tough power grand 850 W”.
If you guys really want to get the best PSU for NVidia RTX 4090 with a build of 13900K then you should read our article about “Best PSUs for Intel core i9-13900K“, there we have recommended the best PSUs for RTX 4090, and intel core i9-13900K.
The best thing about this PSU is 850 Watts of power and the price of the PSU which is totally worth it, this PSU is a fully modular PSU that is rated as 80+ Gold and this rating is quite efficient. The reason we recommended this PSU for NVidia RTX 4070 Ti is the efficiency and wattage that this PSU is all about.
At a price of below $150 it is really hard to find a good 850 W PSU for NVidia RTX 4070 Ti that’s why this PSU is worth buying if you are looking for the best 850W PSU. The performance of the PSU is very impressive, it has very low vampire power thus reducing the cost of electricity, and power usage will be minimal while the PSU is idle.
This PSU comes with 6 PCIe Connectors so you can connect many PCIe components to your PC. The unique thing is that this PSU has built-in RGB lighting which can also be controlled manually, this further improves the looks of your builds. The PSU has Hydro Dynamic Bearing Fan which allows minimal noise at top speed, thus the PSU is great for quiet environments.
There are some bad points about this PSU that I will like to mention and clear to all of you, the first one is the price-for-performance ratio of this PSU which is lower than the above “EVGA 220-G5-0750-X1 Super Nova 750 G5” because this PSU has loose load regulation which means that this PSU is having less potential for maintaining a constant and stable voltage or power, thus this can cause some performance instabilities but not all the time because the load regulation is not that bad.
The other thing I will mention as a con of this PSU is its transient response which is not good as required, it has just an average transient response meaning that this PSU cannot perfectly respond to sudden load changes which also can have an impact on the performance if a sudden change in load occurs.
