PSU worries

[FNHack]

I'm having some concerns about powering a HDD from the dreamcast. After some searching I found this post from member ozone...

“btw, it’s probably not a good idea to run a big HDD on the poor DC power supply.
It struggles slightly to spin up (fan slows down for a second), and will probably kill the PSU eventually.
I’m running the 80GB from the DC PSU atm, but it’s worth mentioning that it could damage something in the long run”.

Does this include 2.5" drives using the 44 wire cable or is the concern just towards running a 3.5" 12v drive directly to the psu?

Any help would be great, thanks for you're time.

If you want use both devices on IDE interface, I recommended in any case use separated PSU. If you have BIOS mod and you not use GD drive (or only motherboard) I think you can connect 2.5" HDD to DC PSU. But not 3.5". For it need detach GD drive fully and monitoring PSU temp, because I do not know how it will behave.
I use DC PSU for CF and external PSU for 3.5" HDD.

Thanks for the response. This really helped me out. I've been worried about pulling that much power from the DC's psu.

Thanks for all the work that you are doing by the way. I've had a lot of fun doing this mod.
