Question Ugreen USB/Sata adapter

You can use a 12V 5A power supply electrically (more amps available is OK), as long as it is the correct voltage (12V DC), correct polarity (usually center‑positive), and correct barrel size for the adapter. Using the wrong polarity/voltage can damage the UGREEN adapter.
Now to your main questions (chipset + DVD drive support):

1) Does the UGREEN CM257 / 60561 use ASM1153 / ASM225CM?​

UGREEN usually does not print the bridge-chip model (ASM1153/ASM225CM/JMS578, etc. on the box/manual, and different production batches can use different chips. From what you’ve shown on the box (“For 2.5”/3.5” SATA Hard Drives”), UGREEN markets it as an HDD/SSD adapter, not an optical-drive adapter.
The only reliable ways to know the exact chip in your unit:

1. Check the USB descriptor in Windows (often shows the vendor like “ASMT” or “JMicron”).
2. Open the adapter and read the chip marking (if possible).

How to check in Windows 10 (no disassembly)​

Use a USB descriptor tool such as UsbTreeView (common freeware) and look at the device details when the adapter is plugged in. If it shows something like ASMT or JMicron, that tells you the bridge vendor. (Sometimes the exact chip name appears too.

2) Will it support an ASUS 5.25" SATA DVD drive (read/write discs)?​

What the bridge chip could support (in theory)​

Many USB–SATA bridge chips can support ATAPI/ODD (optical drives) at the chipset level:

• ASMedia’s ASM1153E family lists ATA/ATAPI Packet Command Set support.
• JMicron’s JMS578 explicitly says it supports HDD/SSD/ODD (optical disc drive) and ATAPI packet commands.

So if your UGREEN adapter used a bridge/firmware that fully exposes ATAPI, it might work.

But the specific UGREEN CM257/60561 is often sold as NOT compatible with optical drives​

Multiple listings for UGREEN 60561/CM257 explicitly warn it does NOT support optical drives (Blu‑ray/DVD/CD devices). For example, an EPCOM listing says it is NOT compatible with Blu‑ray/DVD/CD devices. A marketplace listing for the same model repeats “Do NOT support BLU-RAY DVD, CD-ROM, DVD-ROM, …”. Because of those explicit “not supported” warnings, I cannot honestly tell you “yes, it will read/write discs.” The safest expectation is:
Most likely: it will NOT work properly with your 5.25" SATA optical drive (especially writing).

3) Powering the 5.25" drive​

A 5.25" SATA DVD drive needs both 12V and 5V through the SATA power pins. Many 3.5" HDD adapters generate 5V internally from the 12V brick, but not all of them do it reliably enough for optical drives under load. One reseller page describing this model claims it outputs 12V (for 3.5") and 5V (for 2.5"), which suggests internal conversion exists, but it still doesn’t guarantee ODD write support.

4) The practical test (best way to confirm on your PC)​

If you want to test without buying anything else:

1. Connect the 12V supply to the UGREEN adapter.
2. Plug the SATA connector into the ASUS DVD drive.
3. Connect USB to the Windows 10 PC.
4. Check:
   • Device Manager → “DVD/CD-ROM drives”
   • This PC → does an optical drive appear?
5. Try read first (insert a data DVD).
6. Then try write using ImgBurn or Windows built-in burning.

If it does not show up as a DVD/CD drive, or shows but fails to read/write reliably, the adapter likely doesn’t pass ATAPI correctly (or doesn’t provide stable 5V/12V for ODD load).

5) Recommendation (if you need this to work reliably)​

Buy a USB-to-SATA / enclosure explicitly stating “supports SATA optical drives / ATAPI / ODD” (and ideally 12V + 5V power designed for ODD), or a dedicated USB external DVD writer enclosure.

Quick question (important)​

What exact ASUS model is the 5.25" drive (DVD-RW only, or Blu‑ray)?
If it’s Blu‑ray, the chance of “not supported” is even higher, matching the warnings on listings for 60561.

Ugreen replied to my email and said that this adapter uses the chip ASM225CM, designed for use with 2.5-inch and 3.5-inch hard drives

That reply from UGREEN is very helpful: ASM225CM is the bridge chip.

1) With ASM225CM, can it work with a 5.25" SATA DVD drive (read/write)?​

Chip capability: The ASM225CM does support ATA/ATAPI Packet Command Set according to ASMedia’s own product page. That means the chip itself is capable of talking to optical drives at the command level. But real‑world result: Whether your UGREEN CM257 / 60561 will actually work well with a 5.25" DVD drive depends on UGREEN’s firmware + USB bridge implementation. Many “HDD-only” adapters still don’t support optical drives reliably even if the silicon supports ATAPI.
So the correct answer is:

• It might work (chip supports ATAPI), but
• UGREEN explicitly designed/marketed it for HDD/SSD, and optical-drive support is not guaranteed.

What I recommend (quick test on Windows 10)​

1. Power the adapter (see PSU notes below)
2. Connect the ASUS DVD drive by SATA data + SATA power (through the adapter)
3. Plug USB into PC
4. Check Device Manager → DVD/CD-ROM drives and try:
   • reading a data DVD
   • burning a small test disc

If Windows detects it as a DVD drive and burning works, you’re good. If it’s unstable or not detected, it’s the adapter/firmware limitation—not Windows.

2) Is your 12V 5A power supply OK?​

Generally yes if the adapter expects 12V input and your supply is:

• 12V DC
• center-positive polarity (most are)
• correct barrel size

A “higher amp” adapter (5A) is fine; the device only draws what it needs.

Important: 5.25" optical drives need BOTH 12V and 5V​

A 5.25" SATA optical drive requires 12V + 5V on the SATA power pins. Many 3.5" HDD adapters generate 5V internally from the 12V brick, but some do it poorly or not enough for optical-drive load (spin-up + burning). That’s one common reason “HDD adapters” fail with DVD drives.

3) Is it ASM1153 or ASM225CM?​

UGREEN told you ASM225CM, so you can trust that for your unit.
If you want to double-confirm in Windows:

• In Device Manager → Universal Serial Bus controllers (or via UsbTreeView), you’ll often see ASMedia as the USB vendor (sometimes VID 174c). A Linux lsusb example shows ASM225CM often appears as ASMedia VID 174c with product ID 225c.

Bottom line​

• Chip (ASM225CM): supports ATAPI packet commands → possible optical support.
• UGREEN product intent: “for 2.5/3.5 HDD/SSD” → optical drives not guaranteed (even if chip supports it).
• Best answer: Try it; if detection/burning fails, you likely need a USB optical-drive enclosure/adapter that explicitly states ODD / ATAPI support and provides stable 5V+12V.

If you tell me the exact ASUS drive model (e.g., DRW-24D5MT, etc. and what happens when you plug it in (Device Manager result + any error), I’ll help interpret whether it’s a power issue or an ATAPI/firmware limitation.

My drive is ASUS DRW-24F1MT/BLK/B/AS
