Last time I checked it was 150 watts for 8 pins PCIe connector?A single 8-pin can deliver up to 225W safely
These are server GPUs, they use the fans in the rack units for cooling. ITs not passive.Last time I checked it was 150 watts for 8 pins PCIe connector?
also looking at the card , single slot , and passive cooled , how can this card cool 150+75 watts power used ? something is not right here
Anything without a fan on top is called passive .. PC airflow does not mean it is not passive .These are server GPUs, they use the fans in the rack units for cooling. ITs not passive.
Correct this please . the 225 is the Total 150 (8 pins power) +75 (motherboard) = 225WA single 8-pin can deliver up to 225W safely, and the PCIe slot can deliver 75W; we're looking at a possible 300W maximum power draw for the card.
You underestimate what server fans are capable of. There's a reason why people at the office quip about jets taxiing for takeoff when someone powers on a server that had been off. Likewise, people compare the backs of some of the servers to hair dryers. Most components are designed to take advantage of the array of powerful fans near the front. I'm not sure that much airflow and noise qualifies as generic case airflow -- seems more like active cooling with detached fans.Besides , look at the Pic , they are one slot thin cards , Air flow there needs a blower fan on top .. air wont be pushed inside from Server fans enough.

and there is no possible 300 watts here
The writer mistake is clear , he said 225 watts for 8 pins which is actually 150 (8 pins) + 75 (mobo) ... then he added another 75 watts above it. this is not a coincidence.https://www.gpuminingresources.com/p/psu-cables.html
The 150W rating is an artificial limit most likely for "covering all bases" safety reasons. If you build the connectors to the appropriate specifications as defined by Molex (who designed it) and use the appropriately sized wires, you can get well over 150W on an 8-pin PCIe power cable.
