Question Is EVGA Supernova 850 P5, 80 Plus Platinum 850W the right PSU for future build?

[luisperera89]

I already bought 7800X3D and I'm planning on buying the upcoming 4080 Super. From my old build I'm planning on keeping EVGA Supernova 850 P5, 80 Plus Platinum 850W. Will that PSU be good enough for those two components?

Here are details of the components in my current build:
- EK Mana distro plate
- 2 HDD of 7200 RPM
- 1 HDD of 5400 RPM (will be replaced soon)
- 1 SSD
- 2x16 RGB RAM
- 2 NVME SSD
- 6 RGB Fans
- Usual usb 3.0 and 3.2 + sound for the case

Thanks in advanced!

P5 is an entry level Platinum rated unit with outdated platform. I don't recommand it with recent hardware. You better look for an ATX3.0 PSU. Good start is to read https://hwbusters.com/best_picks/best-atx-v3-0-pcie-5-0-ready-psus-picks-2023-hardware-busters/

Is it because of the wattage or something else? I don't plan to overclock any time soon

Nothing wrong with the wattage. The internal design of ACRF+DC-DC ATX2.4 is outdated for recent GPUs. You need a ATX3.0 unit with LLC+DC-DC platform and PCIe5.0 connector.

Quick update, I went with the ASUS 4070 TI Super and it's been working fine, I planning upgrading the PSU next time I upgrade the GPU. Thx @--SID-- for your guidance.
