I own an HP Z620 and recently added an Asus Turbo GTX 1080 from a relative. The system runs smoothly, with no issues in post or windows, and the graphics card is recognized. I can play games, PUBG at around 30 fps, and Halo Infinite at similar levels. There seems to be a problem. On the GPU Z, it indicates the card isn’t getting PCIe 8 power. I had to switch to a 6-to-8 pin adapter, but the PSU supplies more than expected. Originally the machine came with adapters, but they’re no longer available. The GPU clock is set at 139 MHz and can’t be adjusted via afterburner or Asus tools. The Z shows insufficient voltage, not watts. I’ve tried various fixes: BIOS updates, driver reinstalls, Windows updates, cable swaps, speed settings, power control tweaks, NVIDIA controller adjustments, PCIe slot changes, and even the Asus tuning app. Setting power to 100% didn’t help. I’m planning to remove the PSU and test it with a multimeter tonight. I suspect the card might be faulty. I bought a new 6-to-8 adapter, though it’s not ideal, but others have had success with it. I’m open to other troubleshooting steps without that adapter. Over the years I’ve handled many computer issues, mostly software, and this one is hardware-related. I’m a Mac user and manage big AV networks. The system runs Windows 10 Pro with the latest HP bios, a 1600 MHz 4GB RAM, 8GB 4GB SSD, and the GTX 1080 at 800W, 90% efficient.
