I have a 3TB HDD + 6TG HDD + 250GB SSD + 32GB SSD

with my old system , my psu had 4 sata power cables so I connected each HDD with single cable and 2 SSD's with a single cable .This is my older system https://www.userbenchmark.com/UserRun/28815028 , note the "WD Green 3TB (2011) " performance 72%

but my new psu has only 2 sata power cables so I serried each HDD with a SSD with each cable . And this is my new one https://www.userbenchmark.com/UserRun/35411151 , note the "WD Green 3TB (2011) " performance that is dropped to 57%

My psu has couple of other mulex cables too, should i get a mulex to sata convertor and seprate the power for each hdd? or this performance drop has nothing to to with the power cables?



And also I have "intel rapid storage" activated in my new system. could it be because of this?

If your specs are that listed in your sig space, please find it in your heart to list them in the body of your thread since sig space specs can and will change over time. When that happens this thread and it's accompanying suggestions will be irrelevant to the user in the same boat as yourself.

That being said, what is the make and model of your PSU? CoolerMaster is the brand while 650W is the wattage, it does not state the model from their portfolio. You're advised on powering the devices in your system with native connectors and now adapters. On that note, if your PSU doesn't have the necessary connectors for your build, you're not using the right PSU for the job.

"or this performance drop has nothing to to with the power cables? "

Nothing to do with the power.
I suspect UBM might be giving a poor reading, due to it maybe waiting for the WD Green to spin back up after putting itself to sleep.
