You do have to factor in the 12v and 5v. Unfortunatlly, without specs from the manufacture (which may not always be avalable, welcome to computer hardware), you have to play a guessing game and maybe take a little risk (most liklly wont hurt the hardware, at least not at first), but if it crashes/corupts (at all), It might be a good sign that there is not enough power. I’m just going on a wild tangent here (I really don’t remember accuratlly), but I seem to recall benq burners (earleir models anyway), having a habit of performing very badlly if they do not have enough power. Tht might be a good indication, if you try it and your burner has problems.
As far as actual power, you are really playing a guessing game (a possibly dangerious one). People go off on how inportant a power supply is for your computer (and I’m defanatlly one of them). While it is most important to the motherboard/cpu/ram, it is important to every device in your system. I’m a little nervious running that pow max power supply at all.
If you are good with electronics, here is a test. With the enclosure open so you have access, check the voltage on the lines with the computer running and one device installed. Just tap into the molex’s that feed the drives, and hook up a multi meter. Check both if you have two multi meters or one at a time. With the drive conected, a multi meter conected, and the computer on (conect both before you power up), check voltages with just a hard drive (at idle for a little while). Then check what happens with sandra file system test running (or anything that will max the hard drive). then hook up both drives. Monitor it with it just idle. If the voltage is very much more unstable, stop there, it probably isn’t providing enough power. If it is still stable (fluctuations are fine but should be close to voltage), with both drives hooked up, check voltage with one drive taxed (Like during an actual high speed burn, and or a sandra benchmark, but NOT both at the same time). If voltages are still stable, then do both, tax your burner (like a high speed burn), and tax your hard drive (like a sandra benchmark on the hard drive), at the same time. If voltages remain stable, do it again, if they are still stable, the enclosure is woring fine and the power supply seems to handle both drives just fine.
I’m sorry and that seem very complicated, but without any specs or brand to go off of, thats the only way I know to test a power supply?
Fyi, if there are any ul numbers/symbols+numbers on it anywhere, you might be able to track it to the manufacture if the power supply is seperate (it may be built in but still seperate).
Hope that help some.
