650HX and tri/quad 5850?

post #1 of 19
Thread Starter 
I wonder if it is possible to run 3x 5850 on a HX650?

cpu would be 1.325v 3.40ghz 965BE.

2*2gb DDR2 800.

Asus M4A78-E Motherboard.

6-8fans running at 600-1100rpm.

Maybe 8x 5400rpm harddrives but not if can't have trifire/quad 5850.

Quad is definitely out. Tri is extremely close.

Based on what AMD's site says, I think that you'd be at the limit if you were to have three 5850s in Crossfire. But if you were to only have two, then you'd have more than enough power.

sorry I meant motherboard powerconsumtion, incase of tri I'm actually going to change motherboard.

I am running 2x 5850 right now, cpu overclocked.

might consider trifire but I have to make some more research if my psu can handle it.

It might be at the limit for powering a system with three 5850s in it, but I think it would certainly work. I mean, you'd have room for small upgrades, but it certainly wouldn't power a system with four 5850s in it.

is there any device to measure total watt used?

I guess I need to remove Harddrives and not overclock cpu?
my cpu i s currently 3.7ghz/1.40vcore.

You would be cutting it close (nothing wrong with having your PSU at or near full load though) but I'm pretty confident it would work.

The easiest (and cheapest) way might be to measure it at the wall and then try to guess that your efficiency is between 80 and 85% in order to figure out what your system is drawing from the PSU. Such a device would be the Kill A Watt:

http://www.newegg.com/Product/Produc...82E16882715001

So you take the wattage reading and them multiply it by .80 for 80% efficiency, or .85 for 85%.

For example: if the total power draw at the wall under full load is 400W, and if the PSU's efficiency during the power draw is 85%, then that means the system was drawing 340W from the power supply. But if the efficiency were 80%, then the system was pulling 320W from the PSU.

does this mean that a HX650 gives MAX 650w from the wall and 650*0.85= 552.5w at most to pc components?

google TDP: CPU: 125w + 3x GPU: 3*170 = 635w, ouch?
