Hey everyone! I'm looking for some advice on my power supply unit (PSU) as I'm planning my PC build on a budget. Here's what I have:
- GPU: RX 9070 XT
- CPU: Ryzen 7 7700 (considering an upgrade to 7800X3D later)
- RAM: 32GB DDR5 7200 MHz
- AIO cooler: 240mm
- Case: James Donkey Stark S800
- Standard SSD and a few fans
Currently, I'm using a 750W PSU that came with my case, but I'm worried about its quality.
My main questions are:
1. Is a 750W 80+ Gold PSU sufficient for this setup?
2. Should I upgrade to an 850W PSU to better handle GPU spikes and future upgrades?
3. Is investing in something like the Corsair RM850x worth it compared to cheaper alternatives?
I'm not looking for extreme upgrades like an RTX 4090, just something reliable and steady. Thanks for your help!

The PSU is crucial for your build! I think the Corsair RM850x would be a solid investment. It's a reputable brand, and you'll get great reliability. With your setup, it sounds like a safe bet for future upgrades, so you won't have to worry about power spikes either.
Just to add, that 9070 XT can draw about 600W at peak. So opting for an 850W PSU will definitely help handle any spikes and keep your system stable.
If you're really on a tight budget, consider the RM850e instead. It’s a solid unit and typically cheaper, while still delivering decent performance.
While 750W could work, I highly recommend upgrading from a no-name PSU for safety. A good quality PSU like the RM850x or even the RM750x is definitely worth it for peace of mind.
To get a better idea of what you need, calculate the total power draw of all your components, including fans and SSDs. Then, add 10-20% for safety. For your rig, an 850W PSU is a good choice to extend the longevity of the build.
