GTX 285 / GTX 295 Power requirement issue

[bluejamesbond]

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

You can run 1 GTX285
You can not run 1 GTX295. (which is basically 2xGTX260s)

 

[bluejamesbond]

why?
Blue Screen

 

[bluejamesbond]

2x285 gtx or 1x295 gtx

which is better?

I agree

 

[Mrbumbum]

2x285 gtx or 1x295 gtx

which is better?

I think 2 285's are better then 1 295 (not including Asus Mars possibly)

 

[bluejamesbond]

why can't i run this 295 gtx

 

[mindless728]

PSU, i would recommend swapping it out for a similar power corsair, seasonic, or pc power & cooling, apevia is a really bad brand (aka, that 680 may only give u 450)

 

[bluejamesbond]

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

 

[mindless728]

that is the main voltage used now in computers

 

[bluejamesbond]

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

 

[mindless728]

that 46 amps or amperes are needed on the 12v rail in order for the GPU to be powered in a system, usually the amps are for the whole computer and are usually exaggerated, even so that PSU can't handle it and that PSU is poor quality, get rid of it, if it goes, your whole computer could go

 

[bluejamesbond]

will this run one gtx 295

or this one

Sorry about all this confusion


thank you

 

[Bluescreendeath]

You need a good 750watt PSU to run a GTX295 + all your other components.

You have neither 750watt PSU (and thus probably not enough amps on 12v rails) and you do not have a good brand name PSU.

 

[mindless728]

just get a good 750w
Corsair 750TX

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

 

[bluejamesbond]

so
http://www.newegg.com/Product/Prod [...] 6817206001

or this one

http://www.newegg.com/Product/Prod [...] 6817104019

will not work
?
just wondering

 

[mindless728]

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

 

[bluejamesbond]

ok...i agree

 

[bluejamesbond]

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

 

[mindless728]

im still saying it would only be like 30 or 40 more for the new PSU and GPU, though it should work fine

 

[Bluescreendeath]

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

 

[AKM880]

What are the rest of your specs? You'd need a nice system to get full use of that GTX295.

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.

 

[bluejamesbond]

i have to samsung t260hd monitor running at 1920 by 1200
and i sadly have a 7300 GS right now
