Transients and power supply recommendation
As I have already demonstrated in detail in my basic article “The battle of graphics card versus power supply – power consumption and load peaks demystified”, higher loads in the millisecond range do exist for short periods of time, which can already lead to inexplicable shutdowns in the case of poorly designed or improperly equipped power supplies. The TBP (Typical Board Power) measured by the graphics card manufacturer or the reviewers is not really helpful for a stable system design.
Peaks with intervals between 1 and 10 ms can lead to shutdowns in very fast reacting protection circuits (OPP, OCP), especially in multi-rail power supplies, although the average power consumption is still within the norm. For this card, I would therefore calculate a graphics card load of at least 200 to 250 watts proportionate to the total system power consumption on the secondary side, in order to have sufficient reserves for the worst case scenario. A short excerpt with higher resolution now shows us the 20-ms measurements (10 μS intervals), as I run them automatically to determine the value:
