I am using an EVGA SuperNOVA 850 G2 to power 4x6TB SAS Drives (HUS726060AL5210 specifically) I cut out the orange wire/3.3v wire to disable the power-disable feature. My SAS controller is a Dell H200 and I have 8087 to 8482 ports but each of them seem to be working.
My SATA power cables are off-brand using 2 COMEAP Sata Power cables for my power supply, 6pin to 3 sata power. I had to use offbrand since the power supply was used before and I threw away the extra cables a few years ago when I built with it.
My issue is that I can power 3 SAS Drives no matter which combination of the 2 Sata Power cables that I got (e.g. 3 on line, or split 2 and 1 between the both of them), but as soon as I try to add a 4th it does not spinup. I've tested each drive and each breakout cable end individually and they all work, so I am suspecting a power issue. Possibly the 5v, but I am not entirely sure.
Does anyone know what could the issue? Let me know if I should include any more details to troubleshoot, thank you!
