Could I run this on a 400W Corsair PSU?

post #1 of 6
Thread Starter 
I was wondering if it would be safe to run a 3870x2 off of a corsair 400W Power Supply for the sole purpose as using it in my HTPC to run XBMC (and essentially playback all my 1080p mkv files).

I know it doesn't come with the appropriate power hook up for it however I have adapters for bolth the 6 and 8 pin power connectors.

The HD3870x2 requires a minimum of 500w. Considering that AMD bases those figures off junk and garbage units, you'll probably be just fine with a 400w Corsair unit. Especially considering it'll NEVER see full load in a media machine.

EDIT:
With a QX9650 (pretty power hungry CPU), and a FULL SYSTEM LOAD (at the wall mind you), here's what it consumes:

Why not? I plan to throw the biggest GPU I can possibly squeeze into the smallest case I can for my HTPC's.

Cheap low end cards can playback high definition content without using a buttload of power. I see this as a waste of electricity, but that's just my opinion.

Either way it should be enough.

The only reason is that I have a 3870X2 laying around at home and my current passive GPU has DDR2 ram, which sometimes takes a few seconds to decode 1080p content when i first load the movie/tv show.

The rest of the system consists of a 80GB 2.5" Hard Drive (which only runs the OS and XBMC) and an Intel Pentium Dual Core G620 Processor which has a max TDP of 65W
