Advice for SLI + Overclock
Hay everyone, Was looking for some friendly advice. Please check my Sig for my current Rig.

Okay im looking at grabing this payday..

- 2nd GTX680
- 16GB RipJaw Ram
- 2x 250GB SSD's
- PSU (Please Advise)

Okay so my current PSU is a 650 which is too low for the SLI setup, im also looking at overclocking my CPU to around the 4Ghz+ marker, Ram and both Grahpics Cards a little as well.

I was thinking about pushing the boat out and looking for a 1000Watt+ PSU, but wanted a strong brand/well known and good quailty so it lasts.

Any Advice is welcome :)

OK so X58 is triple channel RAM. Ideally you want 3 or 6 sticks. Not more or less. Make sure you match the memory if you plan on adding to your current setup.

I'm sure some one will recommend the Corsair AX1200W for the PSU. May as well do it now.

That's pretty much because it is a good choice. :)

Thanks for the input everyone, Well my goal is enough power for the Overclocks on my Ram/GPU/CPU and the extra power for the 2nd GTX680.

It might be worth considering a 3rd GTX680 in the next few months when they drop below £300ish, so the PSU would need to do 3-way (To play it safe, for a 3rd card if i go that way)

ive read for 2-way SLI you really need a 750watt, but i dont think this includes any overclocks or SSD Raids, Watercooling, extra fans ETC.

Thanks again everyone,

Just wondering is there any other PSU's around the 1000Watt marker, that will last a while?

Logic is i dont want to buy somthing i will replace within a year :P

Right with the memory side of things, im running 2x4GB Ripjaw X. Im adding a further 4x Sticks of the same memory [url="http://www.ebuyer.com/264750-g-skill-8gb-2x4gb-ddr3-1600mhz-ripjawsx-memory-kit-cl9-9-9-9-24-1-5v-f3-12800cl9d-8gbxl"]My link[/url] Sooo in total there would be 6x 4GB Sticks. all matching memory (Total 24GB - Overkill i know, but future proof for a while)

Any Other PSU options for the 3-way + overclocks please let me know, im not looking at the cost more the life of the PSU before being replaced.

Can your x58 mobo do 3 way SLI? Mine can't, 2 way only with only 2 pci-e slots.

As for ram, the X58 is triple channel so its optimum to buy a matched triple channel kit. You may get lucky if adding an additional 4 gb to what you have now but a chance it will not match close enough, even if it the same brand/type/specs. May also want to look at the need for 24 gb based on the software you run as it increases the PSU load and can add a lot of heat in the case. Most games and other software are still 32 bit so top out below 4 gb. Assuming win 7 64 can be quite sweet for 64 bit photo or video editing but there is a system cost.

Same goes for a bigger than needed PSU... there can be a heat penalty plus your operating cost is much higher.

If spending money you may want to look to upgrade your mobo anyway so you can go Pci-e 3.0 (which will also mean may mean different socket cpu etc.). Doing all of what you are suggesting on an x58 to support multiple GTX 680's seems like its mixing old tech with new which may not give you the system you really want or fully utlize the new tech.

Yup my board can handle 3-way SLI or 3-way Crossfire, sadly no 4-way :( [url="http://www.gigabyte.com/products/product-page.aspx?pid=3776#sp"]Mobo Linky[/url]

With the memory, i see what you mean now. i did think of it this way. i guess i hope they all match up, or i sell on the 2x4GB's i have and order the whole 24gb in one lot to save the chances.

I was looking into the X79 Boards/CPU's but wanted to leave that until closer to x-mass, the logic is the x79 is new tech so there pushing out the first gen of that tech. give it a few months maybe half a year and im sure there will be massive improvments over what they have now. (Could be wrong)

Thanks again for your help

If you are considering 3-way SLI in the future, then get the AX1200. It can handle 3 cards and overclocks easily.

Hay everyone, Was looking for some friendly advice. Please check my Sig for my current Rig.

Okay im looking at grabing this payday..

- 2nd GTX680
- 16GB RipJaw Ram
- 2x 250GB SSD's
- PSU (Please Advise)

Okay so my current PSU is a 650 which is too low for the SLI setup, im also looking at overclocking my CPU to around the 4Ghz+ marker, Ram and both Grahpics Cards a little as well.

I was thinking about pushing the boat out and looking for a 1000Watt+ PSU, but wanted a strong brand/well known and good quailty so it lasts.

Any Advice is welcome :)

850 Watt is enough for 2 way SLI but not much more than that. Add a bunch of drives and a third video card, you'll be out of juice.

Having a PSU that's "overkill" for the situation is advantageous in many regards, chief among them:

1. Obviously the power's there when you need it. Digital electronics are simple - either the signal's there or it isn't. If it's there, no problem and no ambiguity. If it's NOT there, the system doesn't know to seperate out an intentional low from an environmental, and the strange sets in. Trying to pare things down to the bare minimum leaves too many things - like the true build quality of the PSU itself - outside of your control to provide any real certainty.

and

2. The wider the margin, the greater the safety factor while reducing more and more the workload placed on the PSU. Again, cutting the PSU to the bare minimum causes it to work at or near peak capacities all the time - like asking a body to run a Marathon at 50-meter Dash pacing. Personally, if I'm to go 26 miles anywhere and can't ride, then I'm walking - not even jogging.

I tried to factor in what I thought was a mere 15% safety margin on a highly-clocked Lynnfield 3-Way GTX 470 system all decked out with SSDs, VelociRaptor RAID0s and an IPS monitor.

I'm still trying to sort through the remaining pieces to find survivors after the PSU blew up. And that was with a CoolerMaster UCP 1100.

Pretty expensive miscalculation there...


Edit -

Holy Crap!

I've seen double posts before, but can't say as I've EVER seen a post quote itself until now...
