Does the RX 460's (No 6 Pin) Power Consumption Rise higher than 75w?

[Dylan_111]

Im planning to buy GPU's that run off of the motherboard's PCI E slot (750Ti, 1050, 460), but i dont know if there power consumption can rise higher than 75w?
If the motherboard can only provide 75w of power, can the gpu exceed it or not?
I need to know this because of my low power Power Supply
Thanks.

ithe pci express slot delivers only 75 watts

if the gpu asks for more, there won't be more guaranteed, pci express slot can offer a bit more sometimes on some mainboards, perhans 5 watts more, but it is not guaranteed to happen and some mainboards will just shut down or restart when the load is applied

they depend on the 75 watts delivered by the pci express slot, but they don't use all 75 watts, some of them use only 50 or 40 watts(the 750ti), so you can overclock them a bit, just don't go crazy overclocking them

i do that with a r7 250(uses 70watts more or less), from 925mhz i set it to 965mhz, same for ram, i gain 4 fps more or less, a bit more stable the games i play

don't buy a 750ti, the minimum now is a rx460 2 gbs or a 1050, it is a better money investment and the 750 is very slow when compaered to those two

Thanks dude, the RX 460 No 6 pin can only use 75w anyway i believe, so i think imma go for that one.
I heard the 750 Ti isnt good anymore, but i was just using that as an example of gpu's which use low tdp. i dont think im going to overclock anyway.
Anyways, thanks for the help!

Im not sure how this website works, so i dont know if you'll get this;
Since my psu is only a 12v 18A, the rx 460 requires 21A which is obviously a problem.
Since its running on a PCIE Slot, is the 12v rail still relevant or not? hopefully not because i dont want to get a power supply AND an graphics card since my budget is seriously low.
thanks

You will need to list your full specs, including the make and model of the PSU.
If you have a low power usage CPU like one of Intel's dual cores, then you may be fine. If you have an 8 core AMD, then you have a problem. The power requirements listed with the card always assumes the worse, so will recommend a larger PSU than what you probably need.

i have a i3 2100
its a prebuilt lenovo pc 280w
so if the gpu runs on a pcie slot, does the 12v rail matter?

put the gpu and let us know how it went, surely will be all fine

I was hoping you would say an i3. In short, yes the 12v rail matters. However, as you have an i3, then you won't require 21A on the 12v rail.

Assuming that you somehow run your CPU to it's max TDP of 65w and take 75w from the PCIe slot, that's 140w or just under 12A on the 12v rail. Not much else uses the 12v rail, so in theory you're fine. It all comes down the quality of the PSU that's in the Lenovo, personally I think they're ok, by others may disagree.

I havent got the gpu yet, but hopefully it will be ok.

Ok, ill see how it goes when i buy the gpu. I never really understood the 12v rail thing, but i just assumed it wasnt an issue until i researched more that it could be a problem. thans for clearing that up for me
