PSU Upgrade

Cooners · 2025-01-30T15:42:00+0000

I've (hopefully) got a 5080 coming tomorrow but in all the choas I kinda forgot I only have a 650W PSU. Can anyone recommend a good new PSU (I think 850W will be enough) without going mad as I'm going to get murdered for spending so much money as it is.
I have a a 3900X cpu (going to grab a 5700X3D once I sell my old GPU) on a X570 mobo, a few fans and a couple of NVME's (no HDD's as they are all in my NAS).

At 850W this is your best cheap option, Phanteks are generally reputable, but I don't know about this model. It's ATX 3.0 and PCI 5.1 standard so I'd think it's fairly new. Someone else might be along to advise you mroe about this particular PSU. But i'd guess it'll be fine.

What model is your 650? If it is a good one you'd likely get away with it, especially if you tweak the power usage.

Asus TUF Gold has been on offer a lot lately. At the higher end, maybe Antec's HCG Pro which is derived from a Seaonic Vertex.
