PC does not start after I installed bunch of drives

my hardware:

Asrock z97 extreme 6
Intel i7 4790
8gb x4 DDR4 3200mhz
HBA 9207-8i inspur in slot 2
Intel x520-da2 in slot 4
Intel i350 quad nic in slot 5
Seasonic 760 platinum psu
6x WD Ultrastar DC HC530 14TB drives connected to the hba. I used power cable to motigitae power mode pins.
3x 4tb WD 7200rpm HDD. One is connected via hba and the rest using on board SATA
2x kingston 240gb ssds
2x samsung evo 2tb ssds
1x nvme on board

The problem

I cannot get the PC to start with all drives connected. I made the HBA and I can see max of 7 drives not 8 for some reason. I made sure the cables are working. On the PSU I can use up to 3 sata slots before the PC does not start;essentially, turns on juat enough to turn on the fans then shuts off.

My question:

How to solve this problem? What ia limiting my machine, the psu should be more than enough.

From a stated wattage rated point of view, yes it should be. the question I have is how old is the psu? Just like everything else they do not keep that ratting over time!!!

If you bought that psu with that board and cpu at the time of release it’s roughly 10 years old. And at that age I wouldn’t be surprise if 1 or more of the power rails are out of spec and cannot handle the demands your now making of it.

How are the drives connected? The motherboard spec page specifically states:

On a side note, that old Haswell CPU is really starting to show it’s age, I would invest in a B550 + 5500GT + 32GB DDR4 combo for ~$350-$400. Since the Haswell will idle at 40W and most low power AM4 CPUs will draw 30W at full load, that means a 24/7 operation with ~25W difference would save you at least ~18 kWh a month or ~219 kWh a year. Multiply that with whatever you pay for electricity, and chances are you could make all the money back within a few years and have a faster system to boot.

Your money, time, and power bills though :slight_smile:

Would take Decade to just brake even

Yeah, I pay around 25c per kWh, so for me that is ~54 bucks a year, so for me 5-7 years to break even. That is why I posted what you could save in electricity so you can convert to your own tariffs. :slight_smile:

Edit:comment was offtopic

On topic, has OP checks for the resource exhaustion (m2/sata conflict)

And tried with no HBA, just a couple drives in?

Or drives only connected to HBa, not mobo?

Haswell chips were DDR3 only, and the clocks are too high for DDR3 too.

As for the problem, the power draw from that much spinning rust starting at once is probably tripping the PSU’s protection mechanism. HDDs consume the most power when spinning up and you have a lot of HDDs in one machine.

Try configuring the HBA card to only initialize its 6x Ultrastar disks after a boot delay, and on a staggered spinup.
