Hello guys,

For over a year i've been building rigs and powering gpu's based on this scheme:

But then one google search later, all information i find is that 8pin pcie cable can provide up to 150W, while the scheme says that it can provide up to 288W. If it really was only up to 150W, many of my rigs would be crashing all the time and i constantly would have to change melted connectors, although i never had any problems.

Surely i'm missing something, can someone give me some information?

First let's be clear that PCI-SIG lists the maximum rating of its 6-pin PCI-e connector at 75 watts, and its 8-pin PCI-e connector at 150 watts. That is the safe rating, and you go any higher than that at your own risk.

Cables and connectors can work at high power values, but you need to read the documentation for your equipment to assess the risks.
