GeForce GTX 460 review (roundup with 8 cards)

Yeah, your PSU will be more than enough, dont worry.

 

450w/24a is very nice, just had a look at the box for my 192SP GTX260, 500w/36a.

I wish i didn't have to wait till payday, maybe i can thief the GF's credit card, for a loan of course lol.

 

Advertised GeForce GTX 460 TDP = 150W (768MB) 160W (1024MB)

GeForce GTX 460

* On your average system the card requires you to have a 450 to 500 Watt power supply unit.

GeForce GTX 460 in SLI

* A second card requires you to add another ~200 Watts. You need a 650 ~700 Watt power supply unit.



So i am also happy that i also can buy 2x GeForce GTX 460 1GB in SLI

 

thanks alot

 

Your welcome.

 

You guys think a corsair 400CX (400W) could juice it? That's the the PSU I have. I know nVidia says it requires 450W but we know sometimes those requirements are bloated. The rest of my rig isn't so power demanding (detailed on sig).

 

You can try but, you can get a lot of problems.


What would happen if your PSU can't cope with the load?:

* bad 3D performance
* crashing games
* spontaneous reset or imminent shutdown of the PC
* freezing during gameplay
* PSU overload can cause it to break down




So to be on the save side, ugrade to a better PSU like Min 750 Watt or more
so you do not have to buy a new PSU again if you upgrade your Hardware.

 

A 750 for a freaking 460 is insane man. Not everyone can just toss out money on a completely useless extra 300W.

The corsair 400w will be sufficient.

 

Can you read?

ugrade to a better PSU like Min 750 Watt or more so you do not have to buy a
new PSU again if you upgrade your Hardware.

Yes if you are smart you upgrade to a Min 750Watt and not 500 or 550, so if
you buy new Hardware that will ask more watt's you don't get in trouble.

It can be he will later upgrade to a new MB like a P55 or X58 so he can get a
Second Geforce GTX 460 Card.



And yes 400Watt PSU is a little bit on the low side, but he it's his Computer.


Update: but if he only will stay with his old Computer for 2 years or more and
use a Geforce GTX 460 1GB, then a 400Watt PSU is good Enough.

But it's best to always look into the future.

 

Thanks for the replies. I'm only thinking about upgrading he video card for the time being, that's what my budget allows at the moment. This GTX 460 model is the card I've been waiting for. Nice performance, good pricing and decent power consumption. And since my Mobo supports it, I think it's logical to go for it.

When it's possible for me to do a full upgrade (Mobo, CPU, Memory, etc.) then I will surely get a beefier PSU too.

 

Tomorrow i will receive first Gigabyte GV-N460OC-1GI. Maybe in future i will order another one and make SLI. U think my PSU will be enough ? Corsair CMPSU-650HX

 

Got my MSI Cyclone 1GB on the weekend, and it's a cracking card

Soooo much better than the Palit I had. You can't hear the fan at all. Under load you can hear the air being shifted, but there is no actual fan noise (unlike the palit which was a whiny thing).

The noise of the MSI easily blends in with ambient case noise which is great.

Stock volts were a rather low 0.9750V @ 725MHz.

Upping the volts to 1.0025V gives me 800MHz solid as a rock.

What is even better is that I can run 800/1600/4000 with a fan curve that tops out at 60%, which is pretty much the same noise as my case fans.

Couldn't be happier with it! Sonic Plat clocks, with none of the noise :banana:

 

Guru3D says you must have:



Advertised GeForce GTX 460 TDP = 150W (768MB) 160W (1024MB)

GeForce GTX 460

* On your average system the card requires you to have a 450 to 500 Watt
power supply unit.

GeForce GTX 460 in SLI

* A second card requires you to add another ~200 Watts. You need a 650
~700 Watt power supply unit.



And you have a high end computer so, i do not know you can try but you
can get problems like:

* crashing games
* spontaneous reset or imminent shutdown of the PC
* freezing during gameplay

That 400 Corsair you said you have is a really fine quality PSU. It should power the 460 no problems. As long as you arent driving insane voltage / clocks through your CPU =) Should more than be fine!

As a side note, if your PSU is "struggling" in any way the most prominent way you should see it react is by shutting itself down, meaning PC will randomly just shut off or reset.

Performance issues and most of the things mentioned above are not how a PSU would act in most cases by being over burdened.

They have a OCP circuit in them and that is their true "stress" point, if its tripped it will just shutdown not perform worse.

 

Thanks amdking. Nice to know that because I don't have the money right now to go for a more powerful quality PSU.

I mean, I could get a cheap generic 700w-800w POS (I mean PSU) no problem, but I won't go down that road again. A generic PSU was found guilty of murdering an innocent Western Digital 1TB Green drive and a young 4GB GSkill memory kit from my rig. Eventually, the sucker suicide himself.

So if this one can handle it, then hopefully I'll get the GTX460 shortly.

 

Im not sure about my psu for 460 sli, heres what i have. OCZ Game Xtream 700w pn ocz700gxssli. It only has 2 6 pin connectors and here are the specs.

I know the evga cards come with 4 to 6 pin adaptors but is the amperage requirements too low on my psu? thanks for any help

 

Nvidia recomends 450watts with 24amps on the 12v rails, but they always
say to high Watts and AMPs.

The Geforce GTX 460 draws around 13.5 amps or 160 watts just by it self on
the 12v rail.

The Geforce 8800GT draws around 9 amps or 105 watts on the 12v rail.

So it has to work.

 

Good thinkin, cuz a quality 400watt PSU such as yours will be able to handle power much better than a cheap 700watt...many cheap 700watts are rebadged 300-400watt units. They end up dying sometimes when you put too much load on them =P

 

That should be fine, remember the PCIe PSU connectors dont power the card alone, there is some power coming from motherboard as well, forgot the exact watts from PCIe slot but yeah....
So if that PSU is indeed a 4 12v rail PSU, and the PCIe connectors are on their own rail, then you have 36amps just in those alone and the power coming from the motherboard.

Thats more than enough for a single GTX 460
36amps x 12v = 432watts and they use like a 1/3 of that haha

 

I figured it would 1 ok, but my whole question was about running 2 460's Is it going to be too low amperage for 2 of them? Thanks
