Thanks for that GN video, that explains a lot of what we're seeing with GPUs, PSUs, and mobos.
I've been perusing Newegg almost daily (and Amazon much less so), and watching AM4 ATX mobos almost completely dry up, except for China-sellers in the marketplace scalping boards for 2.5-5x the original MSRP of the board.
Thankfully, I snagged a few micro-ATX B450 boards for MSRP, which will do me for basic gamer and browser builds for the near future. Longer-term, though, I hope supply tightness eases up a little.
PSUs is crazy, virtually nothing available that's "decent" at a reasonable price. (Looking at $300 for a 650W 80Plus Gold??? Crazy. I bought those around BF 2018 for $60.)
I even broke down myself, and bought a few EVGA "White" PSUs, 500W, with a couple of 6+2-pin connectors on them. (They were on sale for $40 + ship + tax.) About the only PSUs I could afford, that would be remotely acceptable for builds. (JG in another thread, basically said that a Potato was a better PSU, when asked about those. Oh well.)
Video cards, still seeing some availability at MSRP, oftentimes when a new card model debuts, on initial shipment, then they sell out, and scalpers take over. Keeping my eyes out for "Factory refurbs".
Snagged 3x GTX 1660 ti (ITX single-fan model) for $230 + tax ea. Those were worth it, I thought. Been seeing GTX 1660 ti 'Gaming X' models for $450. (I paid $310, which was MSRP, for mine, some time ago before "human malware".)
