Asrock Rx 580 D 6 pin connector

[Enedjon]

Can you tell me if the as rock RX 580 Phantom Gaming D not X will work on a Asus H81M-C motherboard? I ordered this card but did not see that it had only one 6 pin power connector and not 8 pin. The RX 580 has 185 watt TDP . Will this card work with only 75 watt from the motherboard and 75 watt from the 6 pin power connector for a total of 150 watt ? This card has only one 6 pin.

Yes, because TDP =/= power draw

If I understand correctly, you're asking if your 6 pin cable from your PSU in addition to your motherboard will power your graphics card?

If so, then yes, it will work.

not from Intel, but Nvidia and AMD actually intend to let the public know how much their components need,

It will work, because this Chinese only card (atm) is the 2048 stream processor variant, pretty much a renamed RX 570. It only has TDP of 150w.

 

but seriously, upgrade your PSU because one without at least a 6+2 or 8pin connector for PCIe devices really suck.

TDP is Thermal Design Power, how much heat a chip will output. It has some but not a total direct impact on how much power it draws. It can give you an idea but is not a direct comparison.

For example this card can draw up to ~246 watts peak

Additionally, to OP's question, PCIe 6-pin on a quality power supply can handle more than 75 watts. It can, in theory, go up to 150 watts give or take.

at the online page there it says it has a 2304, the PSU is a Cooler master 600 watt bronze 80 +
Is ok for this build. But i didn't understand how could a rx 580 have a 6 pin and not 8 pin connector because a rx 580 as i know at its max needs 185 watts.

hopefully the PSU's not below tier 4

 

Not totally sure. Maybe the power limit in the BIOS is lowered, maybe Asrock doesnt follow PCIe spec. It's fine though, after all the extra 2 pins are ground pins and do not supply 12v.
