This may just be a question for clarification and confirmation, but I wanted to make sure there isn't an issue I need to dive into:
I have a brand new system with a MSI GeForce RTX 3090 Gaming X Trio 24GB . As a result I'm still running through benchmarks and stress tests to gauge performance and stability. In online comparisons my performance is good but the numbers always seem to be a bit below where they should be for a comparable system.
I tried some tweaking with Afterburner, but that was unsuccessful with being told that it couldn't stabilise due to power limitations.
I ran various GPU benchmarks (Superposition, Time Spy, Port Royal) while watching stats in GPU-Z and HWINFO. What jumped out at me was that the #3 8-pin connector was pulling significantly less power than #1 and #2. Just glancing at it right now on my idle machine, it's #1 59.3W, #2 45.8W and #3 11W. During benchmarks, #1 and #2 will jump to around 120W, whereas #3 stays behind at around 58-60W.
It should be noted that the *overall* power draw then is measured at around 350W - which is precisely what's documented for the card.
So, now I'm wondering if that notably lower draw on the 3rd connector is an indicator of a problem or actually shows that MSI is limiting the overall draw somehow?
Further info, as considered pertinent:
- 5800X CPU on MSI Unify X570
- Corsair RM850x PSU, each connector to GPU is a separate lead, no sharing
