My soon-to-be-upgraded system specs:

AMD Opteron 180 dual-core 2400MHz (939) -- Upgraded from an AMD Venice 64 3800+ @2400 MHz
Asus A8N-E (bios 1013)
2 X 512 Kingston DDR PC3200/400
Gainward 8800GTS 320MB-- Upgraded from a GeForce 6800GT 256MB
1x Maxtor Diamond Max 300GB SATA HDD
2x DVD/RW drives
+
1x USB external HDD 500GB
1x USB Printer/Scanner
1x Wireless PCI Adapter card
Thermaltake black aluminum full tower blue LED case-- How big is the 8800GTS?
(fans: front; 120x120x25mm fan 2000RPM Rear;120x120x25mm blue LED fan, 2000RPM)
BENQ FP91V+ 19" TFT monitor

500W ATX PSU (Ednet, Germany. looks like a Be Quite Blackline. This company also makes CD paper sleeves and headphones, etc.)
[code:1:b13c8e0733]http://www.ednet-gmbh.de/?lang=de&page=1&cat=10,90,6[/code:1:b13c8e0733]

Output +3.3V@28A; +5V@30A; -5V@0.3A; +12V@34A; -12V@0.8A; +5VSB@3.0A

Is 34a on the 12V rail enough for the 8800GTS and the rest of my system?
Any other comments about the above system would be welcomed. Thanks in Advance.

this is what you have ?
if so they are good,real good german quality ...no fancy looking or commercials but ..GOOD

in europe we use these
in case you didn't know about these take a look...you may add them to your PSU list

No I don't have a Be Quiet but my PSU looks very similar to the 500 watt Blackline model made by the Be Quiet company:

I live in Switzerland. I was surprised that my 'no-name' PSU had 36a on the 12v rail. Do you think I can stick with what I have?

here is a pic of my PSU out of the machine:



the label reads: Output +3.3V@28A; +5V@30A; -5V@0.3A; +12V@34A; -12V@0.8A; +5VSB@3.0A


Any thoughts?

I would say that you should definitely give it a try. Run some stress tests on the rig to confirm stability after the install is complete. If it is stable, then save your money for something else.

Specifically, what stress tests would you recommend?

Run Prime95 in a loop to stress the CPU and 3DMark06 in a loop to stress the GPU.

Hmm..Check out my voltage values. Everest shows:

Idle
Vcore 1.41
3.3 3.26
5V 4.95
12V 11.39

100% load (WinRAR benchmark) for 15 minutes:
Vcore 1.40
3.3 3.24
5V 4.94
12V 11.33

Are my values for 12V normal? This is not for the updated system but the system I have now (3800+).

Your 12V is within spec +-10%(+-1.2V), but I'm more comfortable staying within 5%(+-.6V). As long as you are stable while the system runs the programs that you want, then you should be good. Did you get any lockups or shutdowns while loading the system?

Good catch.

Ran some stress tests with my current system and under load the system is completely stable and 12v voltage values stay at 11.39 (Everest). I have seen on various websites that the minimum 12v voltage value is 11.40. Should I risk trying this PSU with my new 8800GTS?
