Hey guys! May I need some help? i used the Cooler Master Calculator to get the W. i know it's not accurate but i wanna hear from experienced users. If ever I want to upgrade my gtx 680 or SLI it, i would also buy a newer PSU. so the PSU in the new build will also be replaced sometime.
GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.
If this is just a temporary PSU, then get a 550w. However, why don't you invest a bit more money now and just get a 750w PSU for the future? Or is the SLI not set-in-stone which is the reasoning for a lower wattage PSU?
