GTX 460 1 Gb SLI on 700w??

[milbrandt1]

So I recently upgraded my entire pc besides my PSU, at the moment I have an OCZ ModXStream Pro 700w seen here:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341018&cm_re=ocz_700w-_-17-341-018-_-Product

The rest of my rig contains the following:
i7-860 @ 3.8
Corsair H50
3x Spinpoint F3s
GTX 460 1Gb
plus 3 case fans and DVD-Ram Drive

Anyways to get to my question, I'm thinking about adding another GTX 460 1Gb to my build but I'm not sure if my present PSU can handle it. Anyone with experience with this PSU or can chime in?

Thank you Again TH

the 460's draw about 300w at stock iirc so if you've got one of the OC'd model I would definitely be looking for a beefier PS

The GTX 460s in SLi are only pulling 470W from the wall, add in about 150W of CPU load and you are still good.

 

[Timop]

^^Agreed with popatim.

for stock it should be enough, barely. With 550W available on the 12V rail, you're coming really close to its limit with an OCed 870

Based on a few GTX 460 SLI reviews I looked at that OCZ ModXStream Pro 700W PSU should do OK.

This is what TechPowerUp calculates for power consumption for various video cards.

Thanks for the info guys, I'm going to try my luck with the OCZ. Is there a risk of physical damage going this route? Like cutting components short?

Also, WR2, or any of you guys, have any idea where I can get that GTX 460 EVGA Precision Skin on WR2's FudZilla link? I want that thing haha

And Timop thanks for the reply, I feel like you're always there when I ask a question haha, and I appreciate that, Thanks Again

When running any computer on a power supply that has a chance of not being powerful enough, there is a small potential of parts being damaged. With a unit from OCZ you should be fine though because you can be certain that it will have an overload control which will shut it down if you're trying to draw more power from it than is safe.

EDIT:

What even is the precision skin? A physical skin or what?

 

[Timop]

^ Its a skin for the EVGA precision program, which is a nifty OC program like Rivatuner/Afterbuner.

 

[Guest]

Ah right, thanks. I thought that it could be the name of the program but then I thought it would be silly to call a program a "skin" xD

It's obvious now; should've worked it out really.

I'd roll back your CPU overclock to stock for your initial testing. Once you have your system running stable and have tested everything out under load you can start bumping up your CPU in increments, testing as you go.
That should reduce the chance of an unpleasant experience.

I did find one 'knock' on the OCZ ModXStream Pro 700w Hotbox @ HardOCP
I'm pretty sure that unusually hot PSU/case condition they're talking about won't apply to you. The PSU pulled is full rated power @ 40C.

That control panel skin is probably part of the EVGA software package for it's GTX 460.
I didn't see a download option for the control panel software.

Thanks Alot for this WR2, and you're right, I just explored the software disc that came with the GPU and the skin was on there. If anyone wants them (460, 465, 470, 480) let me know and I can upload them to Megaupload.

the ocz modxstream pro 700w has only two pci-e connectors. you will need two molex to pci-e convertorseach needs two molex conncetors.

 

[Guest]

Wow. None of us had actually managed to notice that

 

[WR2]

I had noticed it - but since he owns the PSU already and the molex to PCI-e adapters are in the card's accessory pack I didnt think it was an issue to be concerned about.

Lucky for me I already have like 4 of them , Thank You for the response

 

[hunter315]

Damn, he is right! How did we all miss that?

Chances are each card came with one, my 4850 did, if they do then you will be okay.

 

[WR2]

EVGA are a class act. He might have two for each card.

I received 2 with mine, also have 2 from my GTX 260 card, I think I'm set

 

[WR2]

Be sure to let us know how things work out for you!

 

[Guest]

In that case then it is not a problem

Will do, I probably won't be getting my second one for a month or so, but I'll report back, Thanks Everyone

it has a max of 25a per rail, if pci-e and molex connectors are on same rail they will draw to much power.

 

[Guest]

With dual rail PSUs, it is set up so that the CPU draws power from one +12v rail and EVERYTHING else from the other. Therefore it won't actually make a difference.
