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!
I forget where I saw the data, but you can aim for ≈70-80% power saturation on a Gold or better PSU, and you won't lose anything meaningful in the way of efficiency or longevity (might spin the fan more often).
Double is good for future upgrades, but since this is an older pre-built, they could cut costs that way and still be alright.
