750-103D want: I want to install a 3rd HARD drive but the system will not start

Desktop motherboard has 5 heads SATA (of which 2 were used for the first DvD and HARD disk in the original Setup) and the box has 3 bays for HARD drive, but there is no additional power from the PSU cable.

I installed a new SSD as my main and designated record the 1 TB of HARD drive that came with the desktop as my secondary school and office works just great.

Now I tried to install an another 1.5 TB HARD drive for storage. I used a SATA power cable Y (1 male to 2 females) to extend the existing cable. However, to my great disappointment, the system is unable to start up. I guess that supply POWER 300 watts current is insufficient to start 3 disks to a single supply with extension cable.

Issues related to the:

1] sells HP a 500-watt power supply with power cable for SATA 3 HARD drive?

[2] is a compatible power supply on the market (ie. not HP) who can stand in 750-103D envy? Brand/model and how much?

Thank you.

Hello

Probably, you have misunderstood my response.  Unplug the original HD boot drive.

Your question is not the power supply lack of insufficient power.  I have observed remains with HP computers with a power supply that would support three HDs off a 300 Watt SATA power cable voltage.

Perhaps the third HD is formatted incorrectly or is defective.  The other possibility is that your SATA Y cable connection is defective.  You also need good 5V and 12V.  In addition, if you have made any hardware changes to your PC you have not indicated, then it is possible that you may need a bigger power supply.
