SeaSonic X750 w/ 2x Titan

[lambchops511]

Can the SeaSonic X750 support 2x Titan + i7 3770 no overclocking at all?

 

[Agent-A01]

Should be OK. but cutting it close perhaps

 

[dmoney1980]

here are total system power consumption numbers for a single titan at load playing BF3. This was with a i7-3960X, a 130w CPU. Titan's TDP is 250w, so you can add 250w to the figure below to give you a good idea of the kind of psu you'll need. Should be ok, but it's cutting it close man, I'd jump up to an 850w unit if I were you

Suggest you buy a XFX KM3 850W for much cheaper and forget about it. XFX 750, 850 & 1000W are KM3 - Same as Seasonic and Corsair.

The XFX 850W KM3 are $120 on Sale and Delivered from NCIX.

The 750W XFX KM3 about $100 on Sale.

i mean i already have a X750W... I have 2 titans coming in... should i risk it or should i get a new PSU?

 

[lambchops511]

what is KM3?

I would start with this - http://www.newegg.com/Product/Produc...82E16817151108

or move up to this - http://www.newegg.com/Product/Produc...82E16817151102

You spent over $2k on the video cards, now spend some money on the juice for those bad boys!

I think it will be fine, but your stressing your PSU quite a bit. Long term I'd look for a 850w unit.

XFX 850w units are great.

Approx. 486W for the cards themselves in 2-way SLI. Add 150W for the rest and you're running pretty close to the PSU's rated wattage... I would go 750W at minimum, preferably 850W.

If you can afford two titans then there is no reason not to buy a pus which can handle everything heavily overvolted if required. Id say get a 1000 watts seasonic and chillax.

 

[lambchops511]

Actually I'll be getting the Titans for free... But the consensus seem to be I'll be at the edge and I should get a 1k PSU?

 

[lehtv]

Consensus definitely isn't a 1K PSU. Only one person has recommended it. Three people have recommended 850W.

 

[lambchops511]

Im thinking whether to get even more power now actually, there's a high possibility I might get 4 cards and I want to put them all in one system... I suppose that means I would need a 1250W? I can't find a seasonic for that power on newegg.com ... what would you recommend?

 

[dma0991]

If you could afford 4 Titans, you can definitely afford a higher wattage PSU. With 4 Titans and a Core i7 3770, there would definitely be a CPU bottleneck. I recommend sticking with the original 2 way SLI. As for the 2 way SLI, don't risk it and go for the 850W.

I am getting the Titans for free.. the rest of the system is still out of pocket =\

Its better not have a weak link in a beastly rig. There are others to choose from besides Seasonic. To narrow down your choices, stick with Silverstone, XFX, Corsair and PC P&C. Lepa unit looks good too based from JG's review. There's also the Seasonic X-1250.

 

[Geforce man]

Corsair AX-1200 is supposedly one of the best power supplies out there, I personally always rock corsair PSU's. (HX-850 now)

 

[birthdaymonkey]

Since it's a Seasonic X750, I would imagine you'd be fine.

Before the recent range of Seasonic platinums came along, the X-series was the cream of PSUs. I'm sure they're capable of reliably delivering their rated wattage and then some.

 

[lambchops511]

I find out my lab is using supermicro 1800W PSUs, however they are not ATX format but some custom server format?

I am surprised to see the highest rated seasonic is only 1250W...

Is it a good idea to invest in a 4U chasis + PSU??? That should last me a lifetime? But I guess power supply formats change as well...

 

[UNhooked]

Titan's for free ...Wow! You got People

 

[xeledon20005]

how you get titan for free

 

[TheUnk]

I have 2 Titans, highest I saw my PSU was almost 800 from the wall.

 

[UNhooked]

how you get titan for free

Gotta have people. I got the 4870X2 free before it hit the market Alas don't have people anymore

 

[lambchops511]

how you get titan for free

step 1] become a grad student
step 2] work around 100 hrs per week
step 3] don't complain when you get paid $6 per hour

after you have accomplished step 3, you have been deemed worthy by the research gods and hardware will be thrown at you.

thanks... i think i might get a higher wattage psu, since im going to be running CUDA and that might hit the cores a lot harder than games.
