I'm planning to upgrade my GPU from a 2080 Ti to a 9070 XT, but I'm a bit concerned about whether my power supply will be sufficient. I have a Corsair RM750x that's almost seven years old, and here are the specs of my setup:
* **CPU**: Intel Core i9-9900K 3.6 GHz Eight-Core LGA 1151
* **Motherboard**: ASUS Republic of Gamers Maximus XI Hero LGA 1151 ATX
* **GPU**: Currently using a Gigabyte AORUS GeForce RTX 2080 Ti
* **RAM**: CORSAIR Vengeance RGB PRO 32GB (2x16GB) DDR4 3600MHz C18
* **Fans**: Four Corsair LL120 RGB 120mm fans
* **PSU**: RM750x - 750 Watt 80 PLUS Gold certified
* **Case**: NZXT H700 ATX Mid-Tower
* **AIO**: H150i PRO RGB
* **Storage**: Two NVMe M.2 drives, two SATA III SSDs, and a 3TB Seagate HDD (7200RPM).
Given the age of my PSU and the new demands of the 9070 XT, will it handle everything without issues?

Your 750W PSU should be perfectly fine for the 9070 XT. I’ve been using a similar setup with a 750W PSU on my AM4 platform with a 9070 XT and haven't had any problems at all. Plus, the RM750x is a solid unit with a good reputation.
You might want to test your PSU voltages with a multimeter just to be sure everything is solid before making the upgrade. Also, you can check some guides on optimizer settings to minimize power consumption. If you ever decide to go for an 850W PSU later, I can recommend some options!
Thanks! I'll definitely look into that before I transfer to Germany and upgrade.
I'd say your 750W is the minimum for the 9070 XT. If you have a lot of other components running, you might want to keep an eye on power management, but it should work.
As long as your PSU is in good condition, it should handle the 9070 XT well. The RMx series has a 10-year warranty for a reason! Just keep in mind that your CPU is getting a bit old, which might limit your performance improvements. Also, consider undervolting and optimizing power settings if you're worried about power draw.
Yeah, I'm planning to upgrade my CPU and motherboard eventually, but I really need the GPU upgrade now.

Great, thanks for the reassurance!
