Goodbye my 1200 watt PSU

[Pterosaur]

I lost a 1200watt PSU yesterday, I'm running 6 graphic cards on this rig using an inverter and solar panels, the whole rig consumption is 460watts using an inverter calculator and watt matter, now that the PSU is gone I want to ask if I can use a 700watt PSU I have laying around.

Sure, if the 700W psu have enough cable.

700watt PSU don't normally have enough PCIe 6pin and 8pin plugs this is why I don't go lower on PSU, anything under 850watt is not for me, you should try getting female to male PCIe 6pin to PCI dual 8pin cables.

I have not seen 700 watt power supplies with 6x 8 pins either. Most likely you will have to buy a 900 watt or higher power supply. 850 watt PSUs may not have 6x 8 pin connectors or they will be very short distance on 1 wire, so you have to mount video cards close to each other.

what kind of 1200w PSU was it?

I have one from EVGA. But it is an old one.

only a quick research - i am sure i can find many more

I have a corsair TX850 power supply here with four 6/8pin PCIe cables available, I ended up buying four extenders so now I can power 8 graphic cards that use a single 8pin slot like 1660 Ti and 1660 super, Corsair PSU rocks.

I would not take this power supply for 6 video cards if using an open case. For a closed case, the proximity of video cards is not critical.
For example, I use a 1000 watt power supply, and there are more 8 pin connectors. And I take the cables from the old broken corsair power supplies.

I think you will understand the difference

Sure i mostly use also 1000w psu, but for new mining 6x rigs with Nvidia RTX A2000, a 750w psu is more than enough. I only want to say, that their are 750w psu with 6 or more 8pin connectors for gpu´s  

But why you wouldn´t use such psu in a open case, only because the connectors on the PSU side are close together? That is no problem for the PCIe connectors, only for the SATA connectors, but i avoid this? I have 1 running for 4 years without a problem, and some of my other 1000w PSU has also close connectors and never had an problem.
1x 8Pin PSU side = up to 600w on the GPU side 1x 6Pin PSU side = 450w on the GPU side possible. So on a 750w PSU i never use a line on full wattage.  

Don´t overcook it, it is not so difficult as many think - if you avoid SATA - all is good.

SATA cable is good for mining too, you just have to avoid using high-end GPU on them like RTX3060 3070 3080 and 3090, I'm running a rig with gtx 1650 and 1660 with SATA cable and it's running very cold and smooth, these cards pull just 50watt to 70watt.

Do not provide bad advice on the forums to the general users. People who know what they're doing and can measure the actual voltage pulled through the SATA connector can probably get away with using SATA and know which ones have real 16 or 18 gauge wire. Most cheap SATA adapters use smaller 20 gauge cables or even 20 gauge labeled as 18 with extra thick insulation. These connectors provide too much resistance, burn out and catch fire all the time.

If a card is pulling most of it's power from the riser instead of the PCIe plug based on the way it's designed and configured when overclock, the SATA risers will burn up because the SATA port is not rated for anywhere near 75 watts, not even 45 watts.

It's fine you use 1660 super and Ti on risers that are powered with SATA cable, it's fine for a single card per SATA cable I've seen two friends using it for over a year already and no problem or any burnts.
