Hey everyone, I’ve been spending way too much time lately looking at the upcoming hardware shifts, specifically the jump to PCIe 5.0. It’s pretty wild to read that we’re moving from the 7GB/s speeds we saw with PCIe 4.0 into this new territory where 10GB/s+ is becoming the standard for consumer drives. I’m currently running my Unraid setup on an older 10th gen Intel system, and while it’s been a workhorse, I’m starting to map out a migration path to an AM5 or Raptor Lake platform to take advantage of these insane NVMe speeds for my cache pools. One thing that’s been bugging me, though, is the power side of the equation. As I’ve read more about drives like the Corsair MP700 reaching those 10,000 MB/s sequential reads, I’ve noticed they seem to be getting a lot thirstier and significantly hotter. In my experience, once you start pushing the performance envelope this hard, the margin for error with your power delivery gets a lot thinner. I’ve always just used a high-quality single PSU, but with the increased wattage demands of modern CPUs and now these high-speed drives, I’m starting to wonder if my current power strategy is sufficient. In the past, I had a drive drop out of an array due to a minor voltage ripple on a cheap unit, and it’s made me a bit paranoid about stability. When you’re moving data at 10GB/s, a power hiccup feels like it could do a lot of damage very quickly. I’m seriously considering whether it’s time to look into a chassis that supports redundant power supplies, just for that extra peace of mind, or if a high-end Titanium-rated unit is enough. Has anyone here started experimenting with PCIe 5.0 drives in their Unraid builds yet? I'm curious if you found the power draw and heat to be a significant factor, or if the "real world" impact on your PSU overhead was less than the spec sheets suggest?
