It's no driver issues or graphic card (it's working fine).
I want to know if those voltages that i get are normal.

+3.3: 3.15V (min: 3.12V - max: 3.20V)-->average: 3.16V

+5.00: 4.73V (min: 4.60V - max: 4.78V)-->average: 4.72V

+12.00: 12.10V (min: 11.98V - max: 12.40V)-->average:12.12V

- 12.00:-12.60V(min: -12.93V - max:-12.44V)-->average:-12.62V

-5.00: -5.49V (min: -5.64V - max: -5.34V)-->average: -5.46V

Voltages where taken from Motherboard Monitor 5.
My PSU is a no-name 300W (LC:A300ATX, total output 300W max)

My configuration:
CPU: AMD Athlon XP 2100+ (palomino)
RAM: 512 DDR Infineon Pc2100
2XHDD 80giga Hitachi 7K250 Raid 0
DVD-ROM
SB LIVE! Platinum
Ati Radeon 9800PRo with moded cooling (cpu cooler for gpu)
Cooler: Titan CU5TB
1x 80mm Thermatltake Fan

"I think my PSU is to weak for it"

i think , YES!

u can calculate yourself:

CPU ~70W
GPU ~80W
2xHD ~30W?
Board ~20W?
Fans ~10W
Controller /Audio ~20W
......
weak /cheap PSU are not always 300w even when they are named as 300w
and the fluctuations on the PowerLines are rel high and if it´s too high/low, ur PC will restart/crash

and u can say ,for a PSU, +-5% fluctuations is maximum to be ok

short: My opinion :YES

i almost forgot:
if someone knows more/better than me, PLEASE TEACH ME :D

yes, i also own an Enermax with 460W and if got a "bigger"PC and had never probs with it, since i changed my 4 small HD with 2 Big :-)

but others believes now in the new OCZ PSU, that thing should be great, a test of some PSU it won, the link is on the MainPage, search for it
and i heard, that this PSU is BTX ready, but i can´t remember fully

Mertsch can tell u more :D

OCZ Powerstream? Hmmm, i read about it, it's btx ready, very good quality, a little to overpirced i think but i've heard they are not that good.
Anyway oppinions are different, people have diffrent tastes etc.
I will wait 1 week for research and than i make my choice.
Thanks

I really like my new Powerstream PSU ...
voltages are more then rock stable



note: the instable CPU voltage is motherboard ralated
also not that the detection is quite incorrect some times ... see that 119°C ?
hell on time it even detected 0.00V LOL

this statistic represents 1 full day ...
~12h idle
~6h normal usage
~6h non-stop UT2004
