Do I have enough power?

post #1 of 4
Thread Starter 
I have this as a HTPC rig:
GIGABYTE EP45-UD3L
Q6600@2.8GHz
8800GT (Flashed to 9800GT)
6GB DDR2-800 RAM
1x750GB WD BLACK
1x500GB WD CAVIAR

I only have a 400w PSU to spare...is this enough?

If it's an ATX 2.0 or later it is enough as these PSU have most of their power deliverable on the +12V rails and this is what you need for the CPU & GPU. If it's an older design that supplies much of the 400W on the +5V and the 3.3V then it may not be enough.

Post the specs Amps/Rail of the PSU to give a better feedback.

Post what brand/model of PSU you're talking about. Wattage alone is a pretty meaningless piece of information

Although I agree with the above posters, I'm going to venture a future guess and say yes. That's a pretty meager draw system. 9800GT systems typically eat < 250Watts from the wall. Of course that's 12V draw mostly, so that's why the previous posters requested PSU specs.
