I have a Dell Optiplex 755 and I'd like to add a second hard drive ( 160GB 3.5" SATA Hard Drive Western Digital WD1600AAJS) to have more space available since I think the stock 75GB isn't enough for me. So I'm wondering if I need a new power supply or additional data and/or power cables.
The Mini-Tower has two positions for hard drives. See Manual ........
The two hard drives positions are one next to each other.
Yes, you will need to supply a SATA cable
You need a data cable. That's about it.
I'm really surprised your system came with only a 75GB drive. Are you sure that's right? Seems tiny.
Please post back and let me know if you need more help.
Welcome to the Community
Please let us know what type of chassis you have, as this system model use to come with 4 different chassis type and of those 4, 2 of them have “Two 3.5-inch hard drive bays” and other 2 have “One 3.5-inch hard drive bay”.
If you have two 3.5-inch hard drive bays then you will only need a data cable and an additional power connector should be there on your computer.
Always glad to help.

I have a mini-tower chassis. Is it one with the two hard drive bays? If it is, do I need a SATA data cable?
Just hard to believe the original drive is 75GB. Haven't had a drive that small since my Dimension 4100.
Thanks so much,
I assume my hard drive was sold as an 80GB HD but HD manufacturers treat a GB as 1,000,000,000 bytes and not as the actual value 1,073,741,824, so we don't get the full capacity. :[
Glad to help.
You're correct, but that's still a very small drive. For example, you would have no trouble finding a 1TB SATA drive for well under $100.
Yes, Mini- tower has two hard drive bays available and you will only a SATA data cable to connect a new hard drive.
Please reply for any further assitance
Hello, anybody still watching this thread?
I just looked inside a 755 to add a second drive, and there does not seem to be a spare POWER connector for it, even though there is clearly room for the second drive, and an empty SATA connector on the MOBO.
Am I missing something?
