Is it time to upgrade?

[John204]

I currently have a Toughpower 850W GOLD Semi-modular (PS-TPD-0850MPCG) power supply (not the GF1 versions) but the one that advertises that it is "haswell" ready (4th gen intel). I got this as a gift around 5 years ago. My setup currently includes: CPU: Ryzen 7700x, GPU: RTX 4080, so it is fairly high end. I don't know whether this power supply has any safety features where I could potentially wait until it does fail to buy a new power supply. If someone more knowledgeable can comment on this it would be great. Otherwise, do you reckon that I should just upgrade to a Silverstone Hela 1200R?

it won't be able to handle transients well but if you want to upgrade you can to a 1200w but a 1000w would also be good

Absolutely no reason to "upgrade" if it works fine already

A GPU with 300W TDP can have a peak load spike of 450W. If you 8pin rails can handle that on your PSU, you're fine. 850W is enough for your setup, the only thing you have to worry about is potential safety locks if you pull too much from one of the rails. 

 

Some will say upgrade, but as long as the combined PSU power of 8pin rails exceeds the 150% GPU TDP spike, you're more than okay. Some older PSUs have 850W over many rails and can't actually push that much over just 2-3 rails. So just check that.
