I have a custom build and while everything is up and running, I am wondering if it is OK to have your HDD and an optical drive on the same power cable?

I have two HDD's and two DVD drives. The main HDD and main DVD writer/burner are on the same power cable. I have a 850 watt PS. When I burn a disk, my computer flips out and runs really slow...basically starts doing weird stuff. Is this because of the two being on the same power cable?

Thanks for any input!!

yeah, its not a power issue, whats the full specs for your system? It is likely a bottleneck somewhere else in the system.

^Did you increase RAM voltage? Usually you need 2-2.1v esp. when you have 4 DIMMs.

Could you describe how your computer "flips out" and does "weird stuff"? We may be able to diagnose the problem if we knew what the problem was.

Sorry, I didn't mean to be vague. It basically comes to a stand still. It is slow...almost to the point of shut down. If I try and click on a program, it certainly won't load it. If I already have a program open, such as CS4 and or Bridge, it is unusable, won't load images. This only happens when using the DVD multi drive. Also, many times the drive won't open when I try to use it. And it seems to have a high refusal rate of DVD's that I try to format/burn. It will say that it is unable to format disc. Could the drive simply be bad?
