January 12, 20215 yr Hi All, not sure where to post this. I assume a lot of people here is using LSI 9207-8i to connect hard drives. If you do, please take a look and check out my findings. Before I installed the SAS Host controller card, my system is running about 45w on average. I have 4 SATA hard drive connected. Afterward, it is running about 120 w on average. So the LSI 9207-8i using 75w by itself when it's at idle. I have verified this as I can see all my drives are on standby. Looking at newegg site for description of LSI 9207-8i, It claimed "PCI Power (Nominal): 9.8W" https://www.newegg.com/lsi00301-sata-sas/p/N82E16816118182 Can someone else have the same card take a look at their system and let me know if yout card is running around 9.8w on average. Or is there something I am not setting correctly. Thanks!

I have a Single SAS cable connected to 4 SATA drives. Once I did that, it jumped from 45w to 120w usage. Thanks! Edited January 12, 20215 yr by treecats
January 13, 20215 yr Most power meter ( or equipment) just report wrong reading, pls ref. active, reactive, and apparent power, you need others meter to verify. If HBA draw 70w without active cooling, it will burn-out. Edited January 13, 20215 yr by Vr2Io
January 26, 20215 yr Author figure out the issue, it appears to be a faulty wattage meter. I bought a new one. It's showing correct power usage now. Thanks All! Please close this thread.
