Hi everyone,
It's been many years since I've last built a PC from scratch or even upgraded any parts. I've been using a prebuilt Lenovo Legion Cube C530‐19ICB for several years now and I'm generally happy with it mostly because the case fits nicely in my living room cabinet (hooked up to the TV).
I have an option to purchase a new RTX 40 Series card in a few days for a decent price and I'm wondering which of these will be compatible to my existing PC:
-
4060Ti (8GB)
-
4070 Super
-
4080 Super
I assume I need to check dimensions (not sure if everything has a standard like "full height" etc.) and PSU Watts (how strict are these requirements?). Not sure if there's PCI type/width issues or anything else I need to cover, or what do I get the info for both my PC and each card from.
If anyone can help guide me through figuring out which of these cards could be compatible, I'd appreciate it a lot!
Edit: Seems like the 4080 is too much for my current build (card length, PSU, etc.) but both the 4070 and 4060 could work. Thanks everyone for your advice!
Do you mean a new PSU for any future upgrades, or that I'm pushing it a bit hard with the 4070 and it will give out at some point?
A psu doesn't give out because of load, it gives out because of broken components. Heat might damage a psu but this is just wear. And your GPU will not be using 225W at every point.
It's important to realise how power is drawn from the psu by all components. With normal usage, your components will still ask short burst peaks of power, which is partly the reason to go with large overhead capacity. Your 500W psu might have to deliver 600 or 700 for a millisecond and do this just fine. But a 700W psu does this more comfortably.
So what I'm saying is your 500W psu is fine, until it's not. If your pc turns off under heavy load, the psu is the first part I'd consider upgrading.
