Is 400w good enough fro this?
Hey! I am planning to upgrade i5-9400f GTX 1060 6gb to a i7-8700k RTX 2070 and was wondering if 400w would be enough. I currently use 400w for the i5-9400f GTX 1060 6gb. The wattage calculator said that I'd need 484 but I have seen similar posts saying that it massively overestimates. Help would be appreciated.

I always go with design-maximum figures for selecting a power supply unit. The ASUS® PRIME H310M-E R2.0 packs two PCIe x1 and one PCIe x16 slots, one M.2 Socket 3 with M Key for up to a 2280 solid-state drive, and a CPU power regulator capable of sourcing 100W (the intel® 9th-Generation Core Processors™ i3-9350KF/i5-9600KF/i7-9700KF are rated for 95maxW). That would make 400maxW for the mobo circuitry and expansion provisions and 120maxW for the CPU power regulator. Highest-power-draw implementations of the geForce® RTX™ 2070 use two 8-pin PCIe auxiliary power connectors; each, ideally, should be on its own +12VDC rail. The minimum power supply from these requirements - it's better to have excess power than insufficient - is the Antec® High Current Pro™ 850 Platinum, which packs four 40A@12VDC rails and a dual-ball-bearing cooler and is rated for a +3.3VDC/+5VDC total draw of 130W.

short answer is no. 400W is nowhere near enough for a gaming level computer.
the video card alone requires 400W...

I wouldn't, go with anything below 600W.

"My" power calculator https://www.bequiet.com/en/psucalculator says 335 Watts should be enough, provided you don't use any power for externals through the USB connectors. So a good quality 400 W PSU (i.e. one where the 400 W are actually the sustained power) should do the job - provided it has enough outputs to supply the 2070.
