Hi guys! I have bought an MSI GTX 1070 8GB Gaming X edition. I have some predicament with my power supply. My power supply is a Seasonic SS-430GB (430 watts) and my PSU has no 8-pin connector, only 2pcs. 6-pin connector.
The GTX 1070 has two power socket, one 6-pin and one 8-pin. I have the following questions based on these assumptions:
The 6-pin from the PSU supplies 75w of power and 8-pin supplies 150w (correct me if I am wrong)
According to MSI, the GTX 1070's power consumption is 150 watts, this is also the same on nVidia's site which states that the 1070's requirement is 150 watts: http://
My questions are:
1. If the GTX 1070 consumes 150 watts, why are there two power connectors on the card (one for 75w and the other for 150w) It doesn't make sense. Does it mean I can use one 8-pin connector only to satisfy the 150w requirement?
2. Most of the forum threads I have read (including the manual) says that we should connect both 6-pin and 8-pin, if that is the case isn't it that you will be supplying both 75w and 150w to the card simultaneously wherein the card only requires 150w? If you connect the two then you are supplying 225watts.
3. Can I only use the 8-pin connector (using a two 6-pin to 8-pin adapter)? theoretically this will supply the required power of 150watts right? This will also make me use all two 6-pin power cables available from my PSU.
4. I also read on a forum that if my PSU only has two 6-pin connector, then I can substitute the 8-pin with a 6-pin to 8-pin adapter, this will theoretically provide 75watts + 75watts power, BUT the card has 8-pin connector which should receive 150watts. Can I just use one 8-pin connector (see question 3 above)
4. Will my Seasonic SS-430GB PSU provide enough power to the GTX 1070 or should I replace this?
I have read in PCPartPicker that my PSU is sufficient for the GTX 1070 but the PSU has no built-in 8-pin connector, and most of the forums thread I've read tells me that if the PSU has no 8-pin connector for your graphics card then I should replace it. Isn't it over simplification or is that the best course of action?
My current setup is:
i7-7700
8GB RAM
3 SSD drives
mini-ITX
