MiSTer FPGA Forum

I've got a 2,5 SATA HDD that I could use with the MiSTer, I'm not sure how to power it though.

My setup is powered with a 20W PSU (4A) that's connected to both the USB 2.0 Hub and the MiSTer itself.

Most of the 2.5 HDD cases you can find today are USB 3.0 and they get power through a single USB cable, while old USB 2.0 2.5 HDD cases typically have a Y cable with 2 USB A plugs. That's because, according to its specs, USB 2.0 delivers 500mA while USB 3.0 outputs 900mA.

So, apparently it would be better to use an old USB 2.0 box because with the 2.0 Y cable I'd be getting 1A while with the single 3.0 cable I'd get only 500 mA.

Does this make sense or is there something I'm getting horribly wrong?

I am using an old WB Elements 1TB USB 2.0 HDD which is USB powered, my power supply is rated for 5A (I had it in my junk box). I don't know the power consumption of the drive.

With or without the Y cable?

Sorry, no Y cable.

Update: I'm using an old SATA/USB 2.0 interface (with an Y cable) I found on a drawer and it's working fine.
