Even if that is not considered daisy chain, how do you split the 12VHPWR into 2 PCIe ones? Modify cable ourselves? Or use a 2 X PCIe to 12VHPWR adapter? Either method is not sanctioned by AMD, Nvidia or even the PSU makers themselves. So that means if something goes wrong, warranty is out of the window.
why do you need to plug 2 x 8pin EPS to your motherboard? one is enough.. 2 is overkill.. unless you doing LN2 overclocking..Issue is not enough for 3 x PCIE without resorting to daisy chain or sacrificing one cpu header. If you see the ones I posted, all except the MSI one have only 2 spare PCIe connections on the psu end.
For enuser, .. what GPU are you using? do you require 12VHPWR or you doing future proving? and do you require 2 x EPS for mobo? if yes then get the season vertex lor. if you decide to just use GPU with 12VHPWR, you can just grab any PSU that are ATX 3.0 ready.What you are proposing then is custom method is not something laymen will be keen on taking up. Hence my concern about the issue. If use such method and something goes wrong, will amd or psu maker cover? No right?
Is nothing custom bro.... im just implying that this stupid 12vhpwr connector is nothing special. And in the box. This connector is provided for with every psu atx3.0 purchased. And it is never a daisy chain. Im least concern that things go south. Cause if things go south with their original connector. They better take up the responsibility.What you are proposing then is custom method is not something laymen will be keen on taking up. Hence my concern about the issue. If use such method and something goes wrong, will amd or psu maker cover? No right?
why not, i've been using on both platforms with just one EPS.. run smooth without issues.Will something like a 13900k or 7950x run on a single EPS even if never overclock?
If all atx 3.0 psu got 5 x PCIe then I no need so tao tia already ma. You see the following, where got 5? At most 4 nia. And these are the better and expensive ones. Those that got 5 would be something like the MSI one that costs 599.
I see. if you intend to keep your current PSU and it's still workable on future GPU that requires 12VHPWR connectors. search to see the manufacturer does provide sales on those cables which fit only to your PSU Brand or you can consult Cablemod.com before getting any custom cable for your PSU. they response super fast. https://store.cablemod.com/compatibility/I'm not looking to change now. I'm just thinking out loud about in future if I do decide to change my PSU.
Issue is not enough for 3 x PCIE without resorting to daisy chain or sacrificing one cpu header. If you see the ones I posted, all except the MSI one have only 2 spare PCIe connections on the psu end.
Like I pointed out in my example, there's no issue if the person buys an atx 3.0 psu now to use with a 4xxx gpu. There's also no issue in future if such a person continues to buy Nvidia GPU and if Nvidia continues to use 12VHPWR.
The issue comes up if such a person decides to switch to a gpu that has 3 x PCIe connectors in future, be it amd or intel. How then if the atx 3.0 PSU that they intially bought for the 4xxx got only 2 PCIe connections on the psu end? That means got to either use daisy chain for one of the cables or sacrifice(assuming the model allows EPS to be used as PCIe as well) one of the EPS or switch PSU to one that got 3 dedicated/spare PCIE connections on the psu.
As for the 12VHPWR, my understanding is that he is referring to a 12VHPWR to PCIE connector heads adapter. That means an adapter that connects to the 12VHPWR and terminates in PCIe connector heads so that can use the 12VHPWR on the PSU as PCIe and connect to the PCIe connectors on the GPU. Not PCIe to 12VHPWR one provided by nvidia that is for connecting to a 12VHPWR slot on the GPU. AFAIK, there's no such adapter provided by the PSU makers or gpu manufacturers.
I don't think it is an issue about overloading either because the most expensive models like seasonic vertex px and msi meg provide more PCIe slots on the PSU side.
Arh... understood your concern. Actually i will wait for more PSU to be release then make a decision. Anyway, concern only when want to purchase. But to me, it's best the PSU have 2 cpu, at least 4-5 pcie + 1 12vhpwr.Issue is not enough for 3 x PCIE without resorting to daisy chain or sacrificing one cpu header. If you see the ones I posted, all except the MSI one have only 2 spare PCIe connections on the psu end.
I bought the Seasonic Vertex 1000W.. it has just nice 3 x PCIE 8pin cables which is just enough for my 7900XTX.... but I am still 1 short to connect to the mainboard to support Quick Charge 60W... so without it.. the front type C port on my casing can only do 27W.. which is not a big deal since I dun even use my PC casing USB port for charging.As you all probably know by now, PSUs from here on out will be ATX 3.0 with PCIe 5 12VHPWR. However, I find that most of the current offerings are in a somewhat awkward position with regard to PCIE connections.
For example, seasonic vertex has 4 "PCIE/CPU" connections(not to be confused with connector heads on the cable) on the PSU end. If we use two of them for the CPU, that means we actually only have 2 PCIE connections left, aside from the PCIE 5 one.
So my question is, if we have a 3 pcie 8 pin connector GPU, how then? While NVIDIA GPUs will likely stick to 12VHPWR, AMD ones might still stick to conventional PCIE 8 pin x 3. Also, the common refrain is that we should avoid using daisy chain connectors for GPU, especially for the higher end ones. That's to say, only use separate PCIE cables. As I mentioned, we only have 2 pcie connections left on the PSU end so that means we can only use 2 single PCIE cables if we don't use daisy chain ones. Like that how?
That means we got to either use daisy chain or use only one CPU header. Is it ok to use only one cpu header for high end ones like 13900k or 7950x even if we only use stock(ie non-overclcoked)?
Seems like an oversight. The darkpower 13 lagi worse because it only has two PCIE connections on the PSU end, the two CPU connections cannot be utilized as PCIE ones.
Only the MEG AI1300P/1000P has three PCIE connections on the psu end in addition to two CPU ones.
