ezst036 This is exactly what Nvidia wanted all along. Nvidia gets to reduce its own costs. Who cares if it increases costs on the other side at the power supply side right? Reply

Notton While this is a nice feature to have, it's also not very helpful if the PSU doesn't have a debug LED or something to tell you why it tripped. And that's assuming you can even see the PSU, as the current trend is to cover and hide it. A breaker switch is easy to figure out. You'll hear an audible "click" and the switch will be flipped if you overload a circuit. Reply

hotaru251 & more wasted $ on an issue that isnt theirs and doesn't "fix" the issue it just retroactively powers off. (really hope you werent in middle of something important you wanted to save) All the $ various companies have wasted on this flawed connector they could have ACTUALLY redesigned it by now to actually fix the issue. It is 100% ok to blame nvidia and pci-sig….they arent your god/deity. Reply

KE=MV2 It can be easy to not have the connector fully inserted when you believe it is, as this can require some force. The blue color used on the cable pins are useful in ensuring it's fully inserted. You should see ZERO color when properly inserted into the GPU and PSU. Reply

Yes that is pretty insane. They product they make WireView Pro II GPU looks awesome but so expensive to add on to a card after forking over $1000+. Reply

George³ Is the question how to sell you solutions to problems? It's not complicated, first we will sell you the problems, and then wll sell the solutions to them. Reply

thestryker Nothing is ever going to fix the inherent problem of there not being enough margin of error. With the 8-pin connectors paying much attention wasn't particularly required because each one is wired separately and it is has a giant margin of error. With the 12VHPWR/2×6 connectors one really needs to be mindful of plugging them in entirely, the degree of cable bending and making sure no cables were pulled on. I don't think anyone involved with the design really took into account all of the things that minimized issues in the past. There's nothing particularly alarming from a technical standpoint, but fewer safeguards are a bad thing. Had the connector been limited to 300W I'm not really sure we'd really be talking about it even with the melting that has happened on lower than halo cards. Reply
