RTX 5070 Ti Resurrected Using a Radeon RX 580 as a Power Supply
An unbelievable engineering feat was accomplished by a bunch of hardware enthusiasts from Brazil in the form of resuscitating a completely dead NVIDIA GeForce RTX 5070 Ti. The card suffered from burn-out VRM, and a physical hole broke into the hole. Thus, to avoid throwing it away, they came up with an innovative hybrid GPU.
Building a Hybrid GPU
This is how the team plans to fix the RTX 5070 Ti, not by using an older AMD Radeon RX 580 for its graphics processing capability but as an external power supply. They repurposed the RX 580's entire power delivery system, which became quite an exercise in determination as the two incompatible cards had extensive modifications made to allow them to work together.
The Technical Challenge of Power Management
The most gnarly part of the whole project is the fact that they had to synchronize the two power architectures of the cards. As you know, AMD and NVIDIA have fundamentally different power management systems, and so the engineers had to manually attach the power circuitry and fine-tune the synchronization by hand between the NVIDIA GPU and the AMD hardware implementing the power-delivery circuitry.
It Booted
It was a successful technical trial nonetheless. The modified RTX 5070 Ti booted into life and could handle a few very light tasks. Although it's still a fair way from being ready for serious use, it's good enough for an initial proof of concept that it works.
Future Plans for the Hybrid Card
To advance the performance and stability of the card, the power scheme is the next step for the rest of the team to perfect. The full test bench is next to see how well the card performs under load.
