Question750w PSU + RTX 4070 TI
Hello!
My current setup includes:
Power Supply: be quiet! Straight Power 11 750W 80 Plus Platinum
Processor: AMD Ryzen 5 5600X
Board: ASUS TUF GAMING X570-PLUS
Cooler: Noctua NH-D15 chromax.black 2x140mm
Hard Drive: WD 1TB M.2 PCIe Gen4 NVMe Black SN850 Heatsink
Memory: G.SKILL 32GB (2x16GB) 3200MHz CL16 Ripjaws V Black
Case: Fractal Design Meshify 2 Compact TG
I plan to switch the graphics card to RTX 4070 TI.
On the manufacturer's site, the specs say:
- Total power usage (W): 285
- Power supply needed (W): 700
Is the PSU enough? Are there any connection issues or overheating concerns? I assume the high power draw is mainly from the 4090.
Will the CPU become a bottleneck with this new card?
Welcome to the forums, newcomer! With many AIB partners available, which RTX4070Ti models are you interested in? What is the age of your PSU? If you haven’t bought a PSU yet, opt for a higher wattage and a build quality unit that offers more headroom. Connection issues? Cable burning problems? It seems the issue mainly affects the 4090, which consumes a lot of power. If you’re using the RTX4090, a PSU with at least 1.2KW is recommended. To address the burning problems, ensure the cable is properly seated in the GPU connector. If you can feel a click or latch when inserting it, everything should be fine. The RTX4090 is top-of-the-line and power-hungry, so expect higher energy consumption from this card.

Consider retaining the same SMPS or proceed with the suggested alternatives.
Gigabyte GeForce RTX 4070 Ti GAMING OC 12GB GDDR6X or ASUS GeForce RTX 4070 Ti TUF OC 12GB GDDR6X are good options. They should last around 20 months, which is close to two years. I think I’ll keep using what I have now. Appreciate the suggestion. I’ll keep this in mind while setting up.
If I were you, I'd purchase a 1000 watt Corsair power supply and connect it using the Corsair Cable to link directly to the GPU. That's exactly what I'm planning to do.
I believe your power supply should suffice, but if budget isn’t a concern, I’d think about switching to a reliable 850 watt model which would provide a bit more capacity.
The optimal efficiency for a power supply tends to be near half of its rated load. Therefore, the higher the overhead you need, the more economical it becomes to operate. Of course, these savings can range from just a few cents to a few dollars each month, depending on your usage. It’s best to keep the power supply well below 10% of its maximum capacity, and ideally not exceed 20%. For example, if your system draws 650 watts, adding just 20% overhead brings it to around 780 watts. A 750-watt unit would be more suitable for safety, while 1000 watts isn’t unusual. However, 850 watts seems like a solid choice for a setup aiming for close to 650 watts.
Regarding CPU performance, this is often overstated. Certain games rely more on the GPU, while others depend more on the CPU. CPU-heavy titles will drop in frame rates if your processor isn’t powerful enough, just like with a weak graphics card. A perfect balance between GPU and CPU is rare unless your computer is built around one specific game. The wisest approach remains sticking to what you can afford, without stressing over limitations.
I am considering purchasing a 1000w unit. Will this work?
The RMx Series™ RM1000x — 1000 Watt 80 PLUS® Gold Certified Fully Modular PSU (EU) — or should I opt for the platinum version?
What’s the distinction between these options? Does it affect my setup?
Could you clarify what you mean by that statement? It seems connected to something else.
Here are the links for cables and the back of the PSU.
Which cables should I use, or do I need extra ones?
The budget isn’t an issue. I only play on Full HD 1920 × 1080 at 144hz. Based on the rankings here on TH, checking FPS (especially with ray tracing) suggests the RTX 4070 TI will suffice.
I just want to avoid overspending. That’s why I’m asking these questions on the forum.
That’s why I’m choosing a 1000w model. Thank you for your response.
I plan to play games such as Cyberpunk 2077, Witcher 3 Next-Gen, Red Dead Redemption 2, Valheim, Souls-like titles.
Either one of those Corsair power supplies would be perfectly adequate. Platinum is going to save you a few pennies a day on electricity, of course it's difficult to say at what point a platinum rated power supply pays for the difference in cost between it and a gold-rated in electricity savings. If there's a web article pointing to such a study, perhaps one of the folks here has seen it. I wouldn't kick either power supply out of bed for eating crackers, regardless. Whether or not the additional cost is justifiable is solely up to you, my friend. I'll never recommend against buying the best quality power supply you can get your hands on and afford.
