GTX 285 / GTX 295 Power requirement issue

I have an apevia iceberg 680 Watts.
My pc does not have any extra lights and fittings..2 hard drives...3 cd drives...quad core...and 3 fans...

Can I run a single 295 gtx..

can i run a single 285 gtx..

thank you

why?
Blue Screen

2x285 gtx or 1x295 gtx

which is better?

why can't i run this 295 gtx

does the amps of the 12V have to do anything with this

what does it mean when atleast 46 amps is required to run the gtx 295

will this run one gtx 295

not much more for having only one power cord, and a good PSU that doesnt that down the rest of your system

they would probably work, but the new PSU isnt much more than those units that are just for the GPU's, and like i keep saying the current PSU is really bad, you need a new one anyways

you can close this post...solved..

thank you mindless728 and BlueScreenDeath for all your help

I think i am going to stick with the 285 gtx and in a few months swtich out the psu

OR

I am going to get the 295 gtx with the gpsu and then switch out my other psu in a few months

thank you again

The GTX285 should be more than enough...it's a great GPU. GTX295 is overkill unless you have a huge monitor.

If the OP's current PSU is one of these http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=78, it's not even worthy of being used as a doorstop.

i don't understand what you mean

He means that your overpriced 680Watt power supply, produces no where near that much, it can handle at best 550Watts on its 12 volt rails but likely something closer to about 480 which a good 500 Watt PSU can handle easily for less money too. Basically buy smart not just because its shiny.

Did you read the review?

will i be able to run a 285 gtx on the apevia iceberg 680 watts????????????????????

indeed......
i will switch out my psu in a 3 months but i have to stick with the current psu now
so
will i be able to run a 285 gtx on the apevia iceberg 680 watts????????????????????

please tell me i can

The Apevia is crap. I'd give it a good boot into the nearest rubbish bin before it costs you money. At your res., a 285 would be overkill. A 275 would be appropriate for most games. Ever thought about using an ATI solution? You can get very similar performance, and spend a lot less dosh.

But then again, it's your money to throw away as you see fit.

^ That is shockingly wrong.
For example A Corsair 620W can power a system with GTX295 OC , 3 HDD, q6600@3.7GHz v1.55 with no problem.

Yes for an apevia, because nvidia recommend minimum 680W with +12 Volt current rating of 46 Amps and apevia iceberg 680W have 46A. So it will be fine to power a GTX295.

Also do you care to re-think your shockingly wrong statement?

so you are saying i can run a 295 gtx on current psu

how about on a Visitiontek dedicated power 450 watts.....??

The Apevia iceberg 680W have:
+12V1 22A
+12V2 24A

46Amps in total

Each rail can output that much, however the primary power source for the rails rarely is capable of outputting the max current listed for both rails at the same time. For most of them it seems that the two rails combined can only handle about 80% of what their sum would indicate.

+10

Problem 1) You cant just add up the rails to find out how many amps you have.

Problem 2) Apevia PSUs are low quality POSes that greatly exaggerate their capabilities.
