First, let’s start with the obvious. Purchase price €720 in August 2021 was quite reasonable for the period, as there were no stock available. Is €720 worth it for the performance? If you were thinking of a 2019 purchase, no; if you were thinking of a 2021 purchase, then yes.
Temperatures in a midi tower with water cooling on the CPU: 70 degrees max and it’s not particularly loud.
Rest of PC:
8600k, 32GB RAM, 750W Thermaltake power supply, old (analysis for the power supply below)
Performance in games at 2K resolution
Cyberpunk everything ultra 45-50 fps without Ray Tracing, 70-80 fps without Ray Tracing with DLSS Quality
Battlefield 5 everything ultra without Ray Tracing 100-120+ fps in multiplayer
I’ve only done a little overclocking on the memory because the power limit doesn’t go above 100%
Power supply:
(note: the card has one 8-pin PCI power cable)
tldr
Because it’s old, even though it’s above Nvidia’s recommended wattage, it can’t run the card at full power.
Analysis:
Thermaltake 750W Gold, around 2010-2012, a beast BUT.
The power supply has 4 rails, each delivering a max of 215W, and the card’s maximum is 200W. However, RTX 3000 cards at times when they are under heavy load draw more power than that and thus trigger the power supply’s overcurrent protection because they exceed the rail limit. This also happens with newer Seasonic Focus series power supplies. A possible solution is a combination of 2 6-pin PCI cables from different rails into 1 8-pin so the power is shared and the PC doesn’t shut off. The card works normally up to 85% of its power limit.
