Question Question usb sata adadpter ugreen

I still haven't been able to contact Ugreen; they haven't responded yet.

Using a 12V 5A power supply, does this Ugreen new CM257 adapter support this Asus 5.25" SATA DVD drive and can it read and write discs or no? i use Windows 10

From what U can find, that Ugreen adapter comes in two versions: one with, and one without, a power supply "brick". You NEED the power supply unit with the one model. It plugs into the main adapter body to provide power to the attached drive. That should supply all the power required for an optical drive - it is rated to supply 12 VDC up to 2.0 A, and that is required for the drive's motors. (The power for the adapter's electronic conversions is the 5 VDC supplied at up to 0.9 A by the USB3 connection.)

You have not given us the model number of the optical drive so we cannot check its specs to be sure about power.

I do see in some online posts that some optical drives do not operate exactly as SATA hard drives, and so whether this can work for you may depend on whether the "translator" chip in the adapter that converts (in both directions) between SATA and USB3 interfaces can deal with whatever the optical drive is doing. One certainly would hope it can work if the drive is designed to work with any common SATA port on a mobo, but that might depend on the driver used by the SATA port.

Thanks for that detail. Unfortunately the ASUS website for that drive does not provide any detail on power requirements. So we have to assume that any "standard" SATA power supply connection from a PSU would be sufficient. The SATA standards do not specify any general power supply values. They do require that the connectors and cable be able to carry three different supply Voltages at up to 4.5 A each, but that does NOT tell us what any particular SATA device may use. Of the three Voltages, very few SATA devices actually use the 3.3 VDC supply, and I doubt that optical drive would need that. I expect the max current from the 5 VDC supply required by that optical drive (doubtless for its electronics) is available easily from the power supplied by the USB3 port you plug that adapter into. And I am sure the 12 VDC power supply module supplied with the adapter (which you MUST use), capable of up to 2.0 A, is sufficient for the motors of the drive. So in summary it certainly appears that the adapter you linked CAN supply all the power the drive needs. Of course, it also provides the data communication needs, too.

I would point to one small caution. The adapter says it is usable also with a USB2 port. That is true in many ways except one. A USB2 port can supply 5VDC power up to 0.5 A, whereas a USB3 port can do better at up to 0.9 A. Of course, USB3 is also much faster at data transfer rate. But consider that we do NOT know what current max that optical drive needs at 5 VDC. IF it is over 0.5 A but less than 0.9 A, then this system can work only using a USB3 port. Further, because of this power requirement, I strongly advise you use this system connected directly to a computer USB3 port and NOT via a simple unpowered USB3 Hub. If you ARE going to use it though a USB3 Hub, make sure that Hub has its own power supply module to ensure all output ports do provide the full standard power.
