HP Z840 fails to start with 3070 TI, instead launches Radeon HD 5830
I ran a test and tried to boot the GV-R583UD-1GD without connecting power. I received beeps but didn<|pad|> to fail to boot. It might mean insufficient power reaching the card or a faulty adapter cable. This model doesn’t require adapters—it’s designed for direct use with a 6-pin connection. The 3070ti uses dual 8-pin connectors.
It was power! I moved to different slot and reset some BIOS settings. But the key was using the second PSU in tandem plugging into the 4th 6 pin plug. Now to figure out making it boot... I had to move my NVME ssd thats in a PCI slot. edit: Which this is also a problem... a 1300W power supply isn't enough for a dual cpu system with a 3070.... I need to try and convince my boss a regular AMD system with 32gb of ram and a 3070 is better for my job than this beast.
It's interesting, I'm using an RTX A4500 in my z840 without any problems—it performs quite well. The graphics card has an 8-pin connector, but I'm connecting it with a single 6-pin to 8-pin adapter.
Wiring connects ground and green signal together for synchronized activation. It features a dual six-to-eight pin adapter. One six pin connects externally to the PSU, the other internally. The second six pin also links to the internal PSU. This setup is likely for a 3070 TI model, possibly a refurbished PC. The power delivery might be less efficient than advertised, or the power routing could be suboptimal. It includes dual CPUs.
