I'm looking to add three drives to my system. However, I only have two SATA power connectors.

1. SATA-II 320 GB (OS installed)
2. SATA-II 1TB
3. SATA-II 1TB

I have enough spare molex connectors. when I connects my third drive using SATA power connector (4 pin) system start hanging/freezing and in worst case my third drive disappeared.


Processor: [Intel® Core™2 Duo E8400 @ 3.00GHz
Motherboard: P5E-VM DO
RAM: 2GB (667MB)
Super Drive: disconnected
using built in VGA
TOWERS power Supply AT-400 watt


what should i do?
Is 3.3V necessary for SATA-II.

My question is why molex to sata connector 3.3v orange cable missing. Lets say if i cut SATA connector (including orange 3.3v cable) from other faulty PSU can i use it for third HDD.

Note: I have changed many sata power connector (molex to sata connector) but the result is the same

This guy says you can do it.

Hi muhammad jamil

Your PSU (power supply unit) may not be powerful enough.
Please provide some more information about your PSU, brand and model name or number.

I suggest that you try a known good PSU if you can, you could also try connecting the drive with one of the other HDDs SATA power and data cables to see if the issue is the same.

Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

Thanks for the screenshot :thumbsup:
The results are inconclusive in that there is no +5V PSU reading and if this is faulty it may explain your issues.
Please run HWMonitor and again post a screenshot of the readings http://www.cpuid.com.../hwmonitor.html

Your +5V is showing as being too low and this will affect the performance of your HDDs and USB ports etc.
Trying the HDD that you are having issues with on one of the other SATA and power feeds and swapping in a known good PSU are still my suggestions, a 500W PSU would be best and using a quality brand such as Antec, Corsair or Seasonic is recommended.
