I was reviewing the power phases of my GPU (Rx 9070 Hellhound). There are 8+3 phases of 50A MP87993, which add up to a maximum of 400A.
In the image attached to the post, there is a comment from Buildzoid explaining the heat losses of the 400A configuration of the rx 9070 Swift OC, which is the same as in my 9070 hellhound.
I want to know if, when using a TDP of 300W, how many amps would be passing through the phases when undervolting the voltage down to 0.86/0.9mv for the core. If the power (300W) is maintained, the amperage should increase. Is that not the case?
I understand that exceeding a certain percentage of the maximum capacity of the phases is dangerous in the long term. Buildzoid mentions this when he says that exceeding 350A in this configuration is not recommended.
I want to check if it is safe in the long term to increase consumption to 300W and undervolt in this way. I plan to use the BIOS of an XT.
Thank you very much in advance.
