I have an HD Radeon 7970 GPU and an FX-8350 CPU. My power supply is the XFX ProSeries Core Edition 550W PSU. I'm planning to overclock the GPU but am unsure how much I can push it without risking damage. Will the PSU be able to handle it? How much overclocking is safe for a 925 MHz base clock? Please help. Is there a way to perform a very safe overclock that gives me clear feedback on voltage or temperature limits?

Your system operating at full capacity with standard speeds is approximately 500 watts, which means you should avoid overclocking unless necessary, except perhaps for RAM, as it consumes relatively little power. If you insist on pushing it further, you might reach around 1ghz without needing additional voltage, but be mindful of the close proximity to the 550 watt limit based on your card's power draw. I’ve already pushed my GPU to its limits once, drawing 100 watts beyond its thermal design power. That’s 350 watts in total for that single card—so proceed with caution.

I would attempt to push the 7970 as high as possible with stock voltage. Gradually increase the GPU frequency by 25MHz at each step and continue running the Unigen Valley test until instability appears or fragmentation begins. It’s unlikely you’ll reach 980–1000MHz on stock voltage. Don’t worry about limiting VRAM. Or consider using a RX470 instead.
