DIY Making IBM x3650 M4 8x2.5" HS HDD Expander Power Spliter Cable

 Recently I have project that needs to extend IBM x3650 M4 8 bay HDD expander and the kit in online shopping such as ebay, aliexpress are very expensive due to the card has SAS module.

The picture looks like below cost around USD $300 


Alternatively , I found cheaper 8 x HDD expander and the cable with cheaper price and the LSI 9211-8i (Dell H310) will cost you around $60 which is cheaper then the expander kit.

But the problem is the power cable, you can't buy power splitter from above kit. So I bought two single power cable and solder to 14 pin 5557 molex connector. 

14 pins molex, this one goes to motherboard.

16 pins goes to 8 bay expander.


You need to remove the molex pin with tools mentioned below.

Before I remove molex cable from 14pin 5557 connector, I use multimeter to test the connectivity from end to end.

I have removed one pin by one pin and solder to each other the attached back to the first 14 pin molex connector.

 My Acer Aspire Z3-605 AIO PC speaker has buzzing noise. So I decided to replace the speaker. Unscrew 8 screw from the back side. Total 8 screw at back side Pry up starting from below silver color area. Take out speaker You can see the vibrating membrane or sound film has melted. I search in ebay and the price is about USD $19. So I decided to open and see whether I can just replace the speaker only.  The size of the speaker is 24mm diameter and 10mm thickness. I don't see any label or model no on the back side. I search in google about the wattage of the speaker found it's 3 watts. Then I measured with multimeter and it's 4 ohm. So I searched in China site and found the speaker about SGD $2.  So I just purchased 2 pieces and approximately 2 weeks time to reach to Singapore.  To be continued
