I'm looking to upgrade my graphics card to a 5070 Ti and I'm wondering if my current power supply unit (PSU), which is a Gigabyte AORUS P 850W, is sufficient for gaming and 3D rendering in software like Fusion 360 and Solidworks. I've consulted various PSU calculators, and they seem to give mixed advice, with some saying I need 850W, others 750W, and even 650W, which has left me feeling pretty confused about what I really need. Here's my current setup:
- **CPU:** AMD Ryzen 7 5800X (custom water cooled by Alphacool and Corsair)
- **Pump:** Corsair XD5
- **Cooler:** XP3 Light Copper CPU cooler
- **Radiator:** Alphacool NexXxoS ST30 V2 240mm and Corsair XC5 360mm
- **GPU:** Alphacool Eisblock Aurora GPX-N 3070 Ti
- **RAM:** ADATA XPG Spectrix 64GB DDR4 3200MHz (2x 32GB)
- **Storage:** Samsung 980 Pro M.2 NVMe 512GB, Adata 512GB Legend 710 M.2 SSD, Kingston NV3 512GB, Samsung EVO860 250GB, TEAM GROUP DELTA RGB SSD 250GB, Toshiba P300 1TB, Samsung 870 EVO 2TB
- **Case:** Lian Li Dynamic D0-11 Razer Edition with Chroma Controller
- **Fans:** 3x InWin Jupiter 140mm, 3x InWin Jupiter 120mm, 1x Be Quiet Silent Wing 4

You should definitely check if your PSU is one of the models known for issues. The Gigabyte PGM series has had some exploding reports. It might be safer to consider replacing it with a different brand or model, especially given the upgrade. Just to be cautious!
Hey there! It looks like your setup is pretty demanding, especially with that water cooling and the additional components. Generally, an 850W PSU should handle a 5070 Ti just fine, assuming the rest of your components aren’t drawing too much power simultaneously. Many people recommend having a bit of headroom, so sticking with the 850W is a good choice. Just make sure everything is well connected and monitor the temps under load.
Yeah, I’ve been running an 850W PSU with a similar setup, and it’s worked great for me. Just ensure the PSU is of good quality and you're good to go!
I’ve heard about that too. Might need to look into this! Better safe than sorry.
