In total that equals 1352 watts!
GPU's only pull 75 watts from the mobo, two in SLI would draw 150w
Thats leaving 1202 watts just for the CPU, memory, drives & pumps/fans etc.
I can't even begin to think of a scenario where a motherboard needs more than 1088 watts (24-pin & 8-pin).
What could cause a 1352 watt draw (requiring an additional 4-pin) when there is already a 24-pin & 8-pin?
I am intrigued, lol.
If you take your time to check your PSU spec, you will see which rails the majority of the Power Output go.
Rails exclusive of +12V - max of 120W.
And check the pin assignment on the 24-pin to see if that is capable of 560W.
In a 24-pin motherboard pinout, there are only FOUR +12V rails. Compare that to a 6-pin PCIe cable that is rated to 75W - 150W and you get the idea.
Do not assume maximum theoritical Wattage each type of socket is capable of.
God knows what kind of connector they put into the 8-pin and 4-pin EPS sockets. If you are too keen to look, check out the difference between the actual pins on the 8-pin EPS your mobo has and compare those pins to what your GPU has on the PCIe Power.
8 Pin EPS uses thin folded pins on the motherboard side.
8-pin PCIe uses solid pins.
Modular PSU sockets have solid pins.
Thin folded pins are easily prone to loose connections that result to incidents like burnt EPS sockets.
Again, if your PSU does'nt come with an Extra 4+4 pin EPS, it's just crap. But you can always convert one of those PCIe cables to an EPS if you want to. Simple job. Not rocket science.
