I'm looking to power the following:

EVGA 680i A1
C2Q @ 3.6Ghz
4x1Gb DDR2 1066
GTX260 (700c/1512s/1215m)
8800GTS640(700c/1600s/1000m)
4x7200rpm SATAII drives
Auzentech X-Mystique (upgraded op-amps)
4xUSB devices (mouse, Kb, cardreaders)


I currently have an OCZ GameXtreme 600w powering the system and I've done some power supply calculators online and have come up with ranges from 503w - 692w. Would the Tagan 800w here be good enough?

Here's the specs:
Article Name: TG800-U33 ITZ Series
Article Number: 10075
Power Max: 800W
Protections:
Over Current/Yes, Over Power/Yes, Over Temp/Yes, Over Voltage/Yes
Under Voltage/Yes, Short Circuit/Yes
Type: ATX12V/V2.2 & EPS12V/V2.92
dB: 25@2280RPM
Fans included: 2x80mm
Connectors:
1xMain(20+4pin)
1x12V(4pin)
1x12V(4+4pin)
2xPCI-Express(6pin)
2xPCI-Express(6+2pin)
6xPeripheral Molex(4pin)
1xVGA(4pin)
8xSATA(15pin)
2xFloopy(4pin)
1xGround Wire
Input Frequency Range: 50/60Hz
Input Voltage: 115-230Vac(?10% Tolerence)
Input Current: 18-10A
Output: +3.3V@26A, +5V@26A, +12V@64A(6 Rails), -12V@0.8A, +5VSB@3.0A
Approvals: TUV, UL, CE, CB, FCC,CSA, CRUS, Semko, Nemko, Demko, and Fimko


Thanks,
 
Are you really going to allow the GTX260 and G80 8800GTS to co-exist? ;)

Disregard most online psu calc recommendations.Your current psu is more than adequate for either gpu and your C2Q. You might be able consume 300-325W @ the wall under a torture test, so factor in 80% efficiency and that is a 240-260W load on the psu. Basically that is a 50% worst case load on your OCZ, therefore save your $$ for future upgrades.
 
wow sweet... If I don't have to upgrade I most certainly won't ;)


Anyway, the GTX260 and the 8800GTRS640 are co-existing by my using the GTS640 for physx only and having the GTX260 handle all the graphics rendering. They're not in SLI mode and right now they're working fairly sweet together in that configuration.


:EDIT: Actually... come to think of it after re-visiting the specs was the real reason I was looking to upgrade. The Specs for the 260 call for 36A available on the 12v rails. My OCZ 600w offers JUST THAT... 4 12v rails totalling 36A. Assuming the 260 uses that at full load, that leaves little to nothing left for the rest of the system. The Tagan offers a total of 64A across the 12v rails (6 of them). I'll admit, I'm not too keen on the seperate rails and why they exist, but I've been doing some reading when I can. I still take it a single 12v rail is better?
 
The GTX260's 36A recommendation is for the entire system and not just the graphics card. NVIDIA specs it to use a max of ~185W.

In all honesty I see no benefit of leaving the 8800GTS in your system if you are using <2 monitors and allow it to function as a 2d only card. If you insist on leaving it in then factor in another 50-75W overhead.
 
I like to game, and instead of throwing the 8800gts in a box and letting it collect dust until i find a better use, it provides a very nice function as a physx processor not to mention I do use it with a 2nd monitor. The 2nd monitor has system monitoring functions on it when I'm playing a game, and while I'm working I have a virtual machine in fullscreen on it. I realize I can do the same with the 260, but I'd rather use the gts for physx and not bother the primary card with the function.
