PCI Express 4 No more GPU power cables!

[Kaapstad]

While we are on the subject of nice cable management, there is nothing stopping manufacturers from doing it the same as on the Nano with the power lead at the end of the card.

And thats a board which wont be having 2000W of graphics cards in it. Imagine how many more power connectors they will have to put on the board for enthusiast boards.

It will be a cabling mess running them to several bits of the board. WOuld prefer cabling to the card.

Better if all card manufacturers dis the connector option at the end of the cards personally.

What a mess

I think high end enthusiast boards will continue much as they are with the power going to the cards.

PCI-E 4.0 has to allow the above for backward compatability with PCI-E 1.0 2.0 and 3.0 cards.

Value boards and midrange boards could always have a mix of slots for the next 10 years or so to cover old hardware.

Surly this is only for looks? It would indeed look excellent without the cables but at the same time am thinking what's the point? Mind you I not read anything on this.

Feels more like a ploy to get more money into the economy since you'll need all new parts again.

Always the same - technology moves on yet some are being old and stubborn and not seeing the positive aspects of such a change.

PC's are getting smaller and smaller. Eventually the most powerful 'PC' will be inside our mobile phones - this is just one small step towards that goal. Less cables = less clutter and even smaller cases can be used.

PCI Express 4.0 Will Deliver 75 Watt over PCIe not 300W

Last week some news hit the web that detailed specification of the new PCI-Express Gen 4.0 standard that is being developed. It was indicated that the motherboard slot would be capable of delivering 300 Watts through the PCI-Express slot, this is erroneous as it will remain to be 75 Watt, much like it is these days.

The info was shared to tomshardware, who accidentally got it wrong in their assumptions and findings. The PCI Express group contacted them and shared the info that the guys probably retrieved and thus explained wrong information. The 300 Watts is intended for the certification process but the maximum slot power will remain to be 75 Watts:

Update, 8/24/16, 2:06pm PTCI-SIG reached out to tell us that the power increase for PCI Express 4.0 will come from secondary connectors and not from the slot directly. They confirmed that we were initially told incorrect information. We have redacted a short passage from our original article that stated what were originally told, which is that the slot would provide at least 300W, and added clarification:

PCIe 3.0 max power capabilities: 75W from CEM + 225W from supplemental power connectors = 300W total
PCIe 4.0 max power capabilities: TBD

New value “P” = 75W from CEM + (P-75)W from supplemental power connectors

PMSL like we said all along, putting that much power through the mobo would be expensive and a nightmare.

What do you mean? AMD have already done this with the RX480

Sorry, even though I use AMD cards.....I just couldn't resist.

Like the 480 Nitro's, right? That sticks out of the end rather than the side. Only reason I struggled to get the damn thing installed.

We need more of this sort of thing, they should come with the graphics cards so they are tailor made for each model.

As above - not going to happen guys! Was pretty impractical of an idea anyways.

 

[D1craig]

if the main thing is to get rid of cables then why hasnt a board designer came up with a board that has holes under the gpu at the end of the pcie slot and then went on to make a gpu with the power connectors underneath instead of ontop of the card and then the cables would be hidden?

 

[thelonecrouton]

At this point they should just glue a mobo to the backplate of the GPU and you could plug your CPU and everything else into that.

(The two 980Ti's in my box absolutely dwarf everything else.)
