Power supply requirement for rtx 2070 and i7-8700

[Rhythm]

Currently planning out a build in a case that only accepts flex-ATX PSUs. The best one I could find so far is a Silverstone 350 watt PSU that's 80+ Gold certified. Looking into using an RTX 2070 (170mm long) and an i7-8700 (non-K). In theory it should be enough power, as the tdp of both parts is 250 watts combined, and because the PSU is gold certified, that *should* leave me 300 watts usable.

So in theory it should be enough, but does anybody have any experience with using high performance parts like these with a small wattage PSU? I just want to make sure there's for sure enough power before I order everything.

Also if anybody has any suggestions on flex-ATX PSUs, then that would be greatly appreciated!

I won't comment on if you can run it on 350W or not, but the following PSUs can all put out more power.

• FSP400-60FGGBA
• FSP500-50FGGBN
• ENP-7660B

There's also the modular-moded delta unit Geeek offers, but it is a bit longer.

Thank you! Those Geeek power supplies are definitely looking the best so far, and with more wattage.
