Third psu for mining rig safe ?

w33dhit · May 15, 2021

Hello.

Is it safe to have a total of 3 psu's on a mining rig ?
Currently i got a corsair cv550 connected to the asrock h110 btc+ mobo, then i got a hp server psu 1200watts that one is connected to the five 3070's and their ricers.. now i got 5 leftover pcie 6 pin cables minus three of them for the leftover three risers. Also, i got 3 3070s left too... My question is, is it safe for me to buy a third psu, connect it to the mobo with other psu ( wich one ) and buy a splitter ( link plz ) and connect that new psu to the leftover ricers and gpu so that they are on the same psu ? I mean they wont be with the psu that is connect to the current 5 3070, damn this is confusing... Hope someone understands..

Thanks for any reply !!

If you mean normal atx power supply then you just have to short pin 16 to basically any ground available to trigger the psu, and just leave like that, but you're saying to power the riser, if that's the case i would prefer just to buy another one of those server psu...

Tbh your questions do be confusing to me, so if my answer is unrelated to your questions please reply to me
