Sentinel power warnings with my sn95g5 and 6600gt.

Please help me...This is driving me nuts.
I've got an sn95g5 with an amd 3500+ cpu, maxtor 80gig 7200rpm hdd, nec
7900a writer, and an inno3d 6600gt. I ALWAYS get the sentinel warning
when i boot up windows.

Getting a 3dmark score of 1998 with all that plugged in. And a score of
3317 when i unplug the cd writer (no sentinel warning).

I connect the 6600gt using an extension off of the one that is powering
the cd-writer as its my only option.

As i cant actually purchase a higher wattage silentx psu for my system
in asia (my location), my only option is looking to be to get an
external power supply purely for my vid card... and a) thats riduculous
b) looks ugly c) goes against the point in having a shuttle.

Do you think that it might be that
1) my psu is faulty?
2) i should use a power cable solely for the vid card (and if so.. how
do i get another out of the psu?...my warranty will void too)
3) my cd-writer is taking too much power away from the system
unneccesarily? (its old and hardly works now)
4) could i disable the power sentinel?

Ive tried putting new bios updates, using different vid drivers... no
help

Please help me! my gaming is suffering!


Oh also... my cpu case temperature is approx 35.C , my system temp is
54.C and my GPU core is 62.C. Is this normal? (no overclocking)
