  1. The local Corsair PSU Division has spoken
  2. Mainly demand. Very few people are using SAS drives on USB-only systems, whereas many people would want to connect an old hard drive to a laptop. There's no incentive for anyone to produce a mass-market SAS to USB adapter, so the only ones that exist are small-run and expensive.
  3. If you don't mind having a second PSU, you can get the second board out of the equation by either using a PSU jumper tool (available pretty cheaply) or jamming a paper clip between the green and black wires on your PSU. The real problem is that server boards like this are designed to be used in proprietary chassis where fan mounts, drive bays, etc are all built into the case/backplanes, so they often are missing those features in the way you'd see them on a consumer board.
  4. I'm confused as to what you're saying here. If you're saying that the GPU core would only be as expensive as a midrange CPU, that doesn't add up. CPUs are very small dies, comparatively - they only have a few cores, and clock those cores very high. A 10900K costs $500 and has a die area of only 206 mm^2. Meanwhile, a 3090, the closest consumer GPU to your $2000 number, has a whopping 628 mm^2 of die area. Die area costs tend to increase exponentially, as you have to essentially bet on a larger area of the wafer being perfect - you can reduce the cost with GPUs by oversizing and binning down, b
  5. I don't have a ton of experience with mining pools, but as far as I know your description is kinda backwards. You don't have a share of a fixed pool; rather, the pool is the sum of all of its users' individual hashrates. Your individual hashrate doesn't change much, but as users join and leave the pool, its total hashrate changes.
  6. Those voltages are generally generated as needed at whatever point they're needed, rather than using a dedicated power supply, for space reasons.
  7. Laptops don't use any particular form factor; instead, each motherboard is custom-designed for each laptop model.
  8. If an RTX 3070 is only using 90W, your benchmark is definitely not using it to its full potential.
  9. The entire question depends on the exact memory you're looking at. This is not necessarily true. Performance of memory is entirely based on the timings & speed, and both Corsair and other manufacturers offer a wide range from very low-performing to very high-performing kits.
  10. It depends on the laptop. DDR3 and DDR3L are in theory intercompatible, but some laptops either only support one or the other, or will give you a warning if you install the wrong type.
  11. Oh hey, didn't realize it was the same OP! Yep, if I understand correctly, all 3 combinations draw from separate resource pools, so you can mix and match as you please within those restrictions.
  12. The main two PCIe slots are running off the CPU lanes, while the M.2 and SATA are running off chipset lanes. They won't affect each other. Two of M.2_2's lanes share bandwidth with SATA ports, and M.2_1's embedded SATA port shares bandwidth with SATA_2. I understand this is worded kinda badly, so in answer to your questions: The manual says that ONE sata port is disabled, if the M2 runs in SATA mode. I want it running in x4. Is this possible, or running x4 on the first slot FORCES the videocard to fall back to 8x? Yes. 4x on either M.2 doesn't affect PCIe1.
  13. Do you have XMP enabled and memory installed in the correct slots for dual channel?
