[SOLVED] Will my EVGA 1300W g2 power 5 gpus, where 3 of them needs 2x 8 pin connectors?

[RohanWillAnswer]

I google myself to death on this issue. The thing is, I have three risers, and some splitters, if I want to power RX 6800 x2 plus RTX 3080 and two more GPUS, I need to use 8 pin to 6 pin Y splitter that goes to 6+2 + 6+2 pcie connection. Meaning one rail feeding one GPU with two powerconnectors. Will I risk fire or will it be fine for mining at least?

What are the "2 more gpus"?
What matters the most in this case is not how much the cables can feed, but how much power can the rail feed.
On the spec sheet of that PSU, it can put all 1300 watts on the 12 volt rail, meaning you are fine.
Having Y split cables is fine, just don't Y split a Y split cable using extensions. but since the PSU only has 8 Pci-e connectors, you might have to get a few custom cables added to power all the gpus.

Now, if 1300watts is enough for 5 gpus.
rx 6800 - 275x2 = 550 watts
rtx 3080 - 330 watts
say, 900 watts or so.
The wattages I'm listing are peaks, not averages.
you have 400 watts left on the PSU, if the 2 other gpus do not exceed that, you should be golden.
(Also if you do not have a cpu and mobo connected.)

Thank you so much for your reply. The remaining gpus are 2x Rtx 2060. It's on a Mobo, z590 card, and I7 11700k. I'm mining only, with reduced power and volt on the gpus. I have the custom cables.

The rtx 2060 is a 165 watts peak card.
165*2 = 330
leaving you 70 watts for an i7 11700k and everything else in the machine.

I think it should be fine, but it's on the knife's edge.

TBH, it will probably work just fine, but when it comes to power supplies, you want to be sure.
If you have undervolted the cards as well, and they aren't at peak draw, you should be fine.
