  1. This protection applies to the PSU output, which is DC. As such, impedance isn't really involved. 12V rails were originally not supposed to allow more than 20A (240W assuming nominal voltage) per the ATX12V 2.0 specification, but as power demands escalated everyone just started ignoring that part of the specification. It was dropped in later versions.
  2. Just because the standard supports VRR doesn't mean a particular TV has to support VRR. AFAIK VRR is an optional feature, so manufacturers can advertise HDMI 2.1 support without actually offering VRR functionality.
  3. Sure there's a market, it's just much smaller.
  4. Maybe they should start with apartment simple networking?
  5. Basic files on other drives would be unaffected. Installed programs (including games) would no longer work. But with Steam, for example, it can "discover" those pre-existing files when installing the game, so it won't have to redownload everything.
  6. Yes, but it depends whether the manufacturer actually bothers to make the BIOS update required (and how long it takes them).
  7. The memory controller in that CPU usually can't handle memory speeds that high. If there are no XMP profiles for eg. 3200 or 3000, you'll have to set those speeds manually. You should enter very loose timings initially, then lower them stepwise, testing stability each time.
  8. The Vega 10 GPU used in the RX Vega cards had 12.5 billion transistors. The Navi 21 GPU used in the RX 6000 cards has 26.8 billion transistors. Manufacturing that at 14nm would not be feasible. Way too expensive, way too power-hungry, and even the yields wouldn't be good since the chip would be enormous. Over a thousand mm2 in theory.
  9. Each combination of 2 pixels of 24-bit color would of course be 48 bits. The number of combinations of colors would be (224)2 = 248 assuming you care about the order (ie. black + white different from white + black). So then the theoretical amount of storage required for an uncompressed bitmap of all of that would be 248 * 48 bit = ~ 13.51 Pb = ~ 1.69 PB = 1.5 PiB (exactly).
  10. No, something will always be the bottleneck. Most often the GPU. It's just a matter of how badly it's holding back the rest of the system. If you have like a Ryzen 9 5950X and it's being bottlenecked by a GTX 750 Ti, yeah that's bad. But if it's an RTX 3080 then whatever, it's fine even if it's technically the GPU bottlenecking in most games.
  11. One SATA Express port consists of two SATA ports plus a little extra port next to them. So yeah, B450 supports more than 2 SATA drives. Also bear in mind these figures are just what the chipset itself can offer, it is possible for a manufacturer to add more ports with extra controllers (but uncommon with budget boards).
  12. Task manager isn't always accurate. Try checking the memory frequency with CPU-Z - it should be 1467 MHz (equivalent to 2933 MT/s).
  13. Watts per hour is not a useful unit. Do you mean watt-hours per hour? Also, the wattage rating of the power supply is not directly relevant to how much power the system uses. A 550W power supply can deliver up to 550W DC power to the PC components, but its AC power draw will be slightly higher than the DC power delivery, and it will only use as much as is necessary; if the components draw eg. 200W, the PSU will likely draw less than 250W from the wall.
  14. Samsung does the same thing on its phones. I wouldn't put it past them in the SSD market.
  15. PCIe 2.0 x1 provides 500 MB/s of usable bandwidth. The WiFi card advertises 3000 Mbps which is equivalent to 375 MB/s. So it should be okay.
  16. Not surprising under the circumstances. Over here, shipping companies have been offering a chance to win a prize if you pick up packages within a day from drop-off points (which are swamped).
  17. Great news. Of course the first version of this will probably have some flaws, but it's important to get started on making repairability a priority.
  18. The price difference between 240/256GB and 480/512GB is so small I'd generally go for the latter. Next game you want to play might well have a larger install size so it's nice to have a bit more space to work with.
  19. They're a garbage-tier brand, so they rarely get reviewed. They know their products are crap, so they have no reason to send samples to reviewers. Gold certification only measures efficiency and does not guarantee quality.
  20. 2010 is when Nvidia GPUs were notoriously hot and loud though.
  21. Nobody really knows, but bear in mind we are right on the cusp of a new console generation, where VRAM requirements can increase faster than usual.
