Recommended Posts

Posted · Original PosterOP

So here is my build (approximately) There are a couple more hard drives in there. Anyways How many watt power supply will I need if I intend to go balls to the walls overclocking... I have a 550 Watt power supply atm, but I don't think that will be good enough for my new build... Or am I mistaken?

PCPartPicker says it'll use approx 380W. If you're going to OC your 3900X and 1070, I'd be sure to get at least a 650W PSU, if not higher.

The thing is that I will probably end up getting a pretty crazy graphics card like the rtx 3080 ti or something in the future... So I was thinking if I upgrade to a much beefier graphics card then I probably would want a very high wattage psu.

Then yeah, I'd definitely go for 650W+. 850W wouldn't hurt.

I've got an EVGA G3 850W in my PC with only an overclocked i7 8700K, a GTX 970, a couple hard drives, and an SSD. Sure I'm not pushing it to its limits, but damn has it been quiet, and there's plenty of room for upgrades in the future.

550w is more than enough for a Ryzen CPU and GTX 1070. You didn't mention which 550w PSU you have though.

When/if you buy the RTX 3080ti you can look at whether or not a new power supply is needed. We can't tell you the power requirements of something that doesn't exist that you might consider buying sometime in the future.
