AMD Updates its Statement on Radeon RX 480 Power Draw Controversy

[sutyi]

the loss in one 3.3 V pinn will therefore be 13 = (3,6 * 3,6) times higher than in a 12 V pin at the same power transfered.

was mostly just thinking it out while typing, and what is there to look at?
even with the 12 V pins beeing alowwed more A than a 3.3 V pin i still think the slightly to big power draw problem is blown out of proportions.

Depends really. Even if you have a relatively new budget MB, then you should've been okay even without the latest driver fix. On older budget boards however with cheaper components used, especially having flimsy PCIe connectors in mind, there might be concerns. Having a cheap connector work @ 115% capacity especially for prolonged periods of time probably not a good idea.

This whole PCIe power malarky raised two I think valid points:

1. PCI-SIG certification methods need to be looked at and probably reworked.
2. Why on earth isn't there built-in limit baked in to motherboards, so add-in boards (VGA, soundcard, etc.) wouldn't be able to draw dangerous amounts of current trough slots / pins that are not rated for it?

I dont even understand this problem to begin with, why would a motherboard even be allowed to give so much current via a PCIe slot that it could destroy itself?
Why would there not be a hard limit on that?

Because no one wants to open their computer to replace a fuse, most likely.

There's a replaceable fuse for that????????????????????
