Is it okay to have my 9800 pro and 80 gb hard drive on the same power cord? My power supply is an Antec Truepower 430.
 
I used to run my 9700 on the same wire as my hard drives with no problem. Then I changed mobo's and installed a SATA adapter on one of my HD's and my machine wouldn't boot. I switched to another power line and the problem went away.
I've also read on this forum about someone cooking 3 HD's by running his 9700 on the same line as them.
I don't know if the power requirements for the 9800 are similar, but it probably wouldn't be a bad idea to run it off another line.
 
I would say no. I killed 3 WD 80gb drives running my 9700 Pro and drive on the same power line.

didn't you learn your lesson after the 2nd death?

Actually no. I had no idea what was causing the issue until I decided " Hey let me try this 9700 Pro on its own power line" and then everything worked flawless after that.

Besides I'm used to having that kind of dumb luck.:(
 
is it just video cards that cause this problem? can you hook two hard drives up on the same line?

You don't really want any device that can have high draw in bursts on the same power cable as a hard drive.

Its not good.
May not hurt a CDROM, they're not used as much, but it would probably still be a risk.

all the 3v 5v and 12v hots are coming from the same switching power supply - they are generated from the same coils... so whlie i agree that its not good to have high draw equipment on the same phyical daisy chain whip (possible voltage drops, surges, etc), isnt all the hots connected anyway? what i mean is, each daisy chain whip isnt a DEDICATED 5v, 12v etc feed from the power supply, they're all tied into the same coil, aren't they? or is the problem the raw amperage when you're at these voltages, when too many amps are on one whip, there is more resistance in the line and starts heating up / burning out the drives / devices internally?

'm not tryin to argue, im just curious as to why you say this
 
i had lots of issues with my first Radeon 9700 pro on the same line as my hard drive .. i would hear my hard drive going into a automatic power saving mode (not the power saving mode in windows ) i got worried and shot a email to tech support only to find out that they don't recommend putting the 9700 pro on the same power line as the hard drive .. because it can cause such a surge in voltage at times it would make the hard drive force its self into a Safe mode if you will to avoid serious damage.. needless to say i was pretty worried about it ..and i took it off the hard drive line and gave it a its own line directly to the power supply so i wouldn't have to worry .. no problems after that ..on a unrelated note recently i got a AIW 9800 pro .. it kept giving me visual garbage ..like a matrix style screen garbage .. i couldn't figure it out for the life of me .. i never thought it would need more than a 350 watt PSU which is what i had ..but until i got a new PSU it wouldn't work with dick .. radeon's are just so touchy on power geez ..:eek:

Very true, my 9700 pro was on the same line as the hard drive, and going into 3D mode (i.e. drawing more power) made the HD stall and the computer shut down.

A new and powerful 420W PS and the vid card on its own channel solved all probs. But still and important experience regarding power supplies and video cards.
 
I put my 9700NP on the same chains as my non-controlled case fans. Enermax recently released a new line of PSUs that have a dedicated lead that's supposed to be used with your videocard, and only your videocard.
 
my 9800pro 256mb is on a chain from HDD1 HDD2 and side fan. runs flawless. and using a the 420watt supply that came with my X-alien case.
 
So...its ok to hook up two HDD's on the same power line, or two CD Roms, but just not video cards? Are they too fluctuant in power consumption or something?
