I'm replacing my RTX 3070 (which draws about 240W) with an MSI 5070 Ti (estimated at 300W) this week. According to pcpartpicker, my total wattage estimate is around 628W. I currently have a Seasonic Focus 750W 80 Gold power supply. Will this be sufficient for my setup? I'm planning to upgrade to a 1000W PSU in a few months, but I'm worried because I've seen various wattage estimates from different websites like Newegg that suggest my rig might use significantly more power. Here's my full PC build:
- CPU: AMD 7800X3D
- Cooler: Thermalright Peerless Assassin 120 SE
- Motherboard: MSI B650 Gaming Plus WIFI ATX
- RAM: Corsair Vengeance 32GB (2x16) DDR5-6000
- Storage: Samsung 970 1TB M.2, Samsung 870 1TB SSD, Seagate 2TB HDD 7200RPM
- GPU: MSI 5070 Ti Gaming Trio OC
- Case Fans: 4x120mm

Honestly, I'm not entirely sure. But if you do the math, your total power consumption might hover around 600W when you're maxing out your CPU. So your PSU should handle it, but I would recommend being cautious with such close estimates.
From what you described, it seems like it'll be fine. Your specs look solid for that PSU.
Your PSU should be fine for now. The Seasonic Focus 750W is a high-quality power supply. The AMD 7800X3D shouldn't draw more than about 100W, usually even less. Having a 12V PCIe connector for your GPU is key, and given that the 5070 Ti has a lower wattage requirement than the higher models, you should be good to go. Upgrading to a 1000W PSU later on is a great idea for future-proofing, but if everything's running smoothly, you might not need to rush into it.
Thanks for sharing the info and the link! I'll definitely check that out. : )
True! It's good to have a solid PSU but sounds like you're in a good spot.
If I were in your shoes, I would aim for a PSU around 850W - 1000W just to be safe. Even though it's rated for 750W, it's good to have some headroom for future upgrades. That's just how I see it, though.
Yeah, I'm planning for a bigger PSU in the next few months, but I'm just trying to make do for now without breaking the bank.
The PSU will work but it might not be the safest option since you're running close to its limit.
