Would 650w be enough to power this? - Page 2

post #11 of 36
honesty folks, after i did the switch i have had no issues. at all.

and i am still using the neo eco and 5770 in a different system that is on 24/7. once again with no issues.

yes after i bought the gx750 i heard about the ripple issues. but i have had no issues.

it is working and if i ain't broke i aint fixing it.

and lol at my system being able to be run on a 450w psu! people really underestimate the power consumption of this toxic 6850. my oc'ed 965 and the gpu would annihilate a 450w cpu.

I'm not making this up, in fact the Toxic Edition is hardly more power hungry than a reference 6850 because of the way Sapphire designed the card. Even if they hadn't done that, the Toxic Edition's overclock is negligible and wouldn't make much of a difference in terms of power consumption.

Yes, your system would be fine on a good 450W unit, and I still hold that something was wrong with that Neo Eco 620.

yes definitely something was wrong with ur eco psu
most probably its not providing its rated wattage...and it does not mean it will stop working altogether...that is why it worked after u removed one additional card.....

Your ECO is faulty-or the combination of 5 HDD's and the way you had the 6850 powered(PCIE plugs) was overloading the 12v rail.Re-arranging the way you had it connected probably would have fixed it if the PSU is fine.It is not just the overall wattage-but the available amps on your rails.

It's a single rail power supply, one OCP circuit...

that was the problem. and with the 60 amps (vs. 48 on the neo eco) i now have no issues.

and the toxic 6850 power consumption is ~350 watts or more by itself when it is being pushed. 450w will not cut it. if i wasn't on my netbook right now i would go get the supporting links.

350W is a figure taken at the wall for the entire system, I can guarantee you that.

this is true at idle. i had no trouble at idle.

but when playing challenging games or running multiple graphics apps at once there were instant shutdowns. no blue screen. no black screen. instant shutdown like someone pulled the plug from the wall socket.

the card gets hungry when challenged.

That sounds like the OCP on your PSU was faulty, there's no way your system would ever try to draw >48A from your Neo Eco (48A being its rated power output capacity at 12V).
