I would get the Antec, but the EVGA is not a bad choice at all. My previous comment explains why.

The antec is over 320 and and I cant find any reviews that rate it higher. I know its platinum efficient but thats the only real diff I can see

where has lutfij been?

There she is. Everything i have found on the web google searching says its an awesome performer. The only negative reviews were the few on newegg itself which as we all know anyone can run into issues.

-10 year Long warranty! (EVGA is great from what I read. Hope I never have to use warranty from them so far)
-80+ Gold so less wasted power to make your ungodly amount of power. You may be able to jump a car with that thing 😛

I see no negative aside of the larger size(but you need it for that much power). Well that fact that is has enough power to burns its own wires, but you would have to try to run the entire system off a single molex to do it.

The few bad reviews could be bad luck. It happens.

I could run 4-5 systems on that with power to spare

 

[azzazel_99]

Lol yea with the custom bios on the 780ti its said to be able to pull around 500+ per gpu. I had them running at 1406mhz core and 3600mhz on the vram trying to run valley and thats when it ran outta power lol. The cards in single run at 1406mhz easily.

 

[RussK1]

Like any reviews, customers who mess up will blame the company.

I cannot agree with you more.

The EVGA is good (and a Super Flower) and they do have excellent 24/7 support. But I'm partial to Delta (and Seasonic).

ran outta power? The psu went, "Oh crap, I can't give you anymore power. I give up." And everything shut off instantly? Or was it more dramatic.

 

[nukemaster]

If it is quality it will do exactly that, just shut off. no damage or nothing.

And WOW that 780 ti must have one hell of a VRM system to pull that(500+).

 

[azzazel_99]

I was reading the specifics on the skynet bios and it allows me to run instead of the 115percent power cap I can run 200% power and 1.212 volts. Running at 1406mhz core and 3600mhz on the ram speed at 200% power I can see it pulling that much I guess?.

 

[tiny voices]

I really doubt you would get close to 500w draw per card.

 

[RussK1]

I really doubt you would get close to 500w draw per card.

It won't... you can use KBT and modify the power target to 300% and it would be pointless. The board will only pull what it's designed to pull.

 

[tiny voices]

A stock 780ti pulls like 265w under full load and there is no way you will even get close to doubling that wattage.

 

[azzazel_99]

Then why with the cards clocked at 1406mhz core and 3600mhz memory would the power supply start giving out on a 850hx? Obviously with the second card its pulling more then the 850 the psu is rated at right?

To be 100% honest with you, I do not think your system ran out of power.

 

[azzazel_99]

Runs fine with the cards at the stock settings even on the modified bios. If i run them overclocked i get shutdowns. If i run them indvidually they work perfect overclocked.

EVGA today not only released the clearest image of their upcoming GTX 780 Ti Classified graphics card showing off a robust heatsink design, but they also gave us a clear shot of the impressive power connector configuration as well. In total the board includes dual 8-pin power connectors and single 6-pin power connector and the PCIe rail. Combined this gives the card a max power draw of 450W! That is well over the 250W TDP of the GTX 780 Ti and it is sure to give this card impressive overclocking results. It should also allow EVGA to max out the GPU Boost clock out-of-the-box.

Of course the power connectors are only part of the puzzle when it comes to overclocking the board needs a robust delivery system with chokes, captors and resistors as well. I am sure the VRM is going to be just as impressive as the heatsink and the power options though – this is one card I am really excited to get my hands on!

I SERIOUSLY doubt you will pull anywhere close to 450w per card. I would guess more like 360w max with your modded BIOS and overclocks.

Just because a card has the connectors, do es not mean that it can pull as much wattage as they can give.

I ran 2 6990's a sound card, SSD, 5 HDD's and an OC's 2600K on an HX850 and never had a problem even though I knew I was pushing the limit... reason I bought the HX1050. I'd say it was something else causing your shutdown... have you monitored the output voltages and checked whether they were spec?

 

[azzazel_99]

people are measuring a draw of over 400 on the 780ti already.

Got any trustworthy links for that claim? That sounds interesting.

I dunno if those are trust worthy or not but they recommend a 600w just for 1 and these cards have a max of 450w draw....even if they do 360-390 with the heavy overclock thats on them thats still very close to 800 already plus the fans in the case, the sound card, the ssd and hdd i have plus the cpu overclock. Im willing to bet im flirting with that 850w line.

 

[tiny voices]

Well, your first link doesn't give any facts. Your second link is TOTAL SYSTEM WATTAGE, which includes a top of the line ASUS overclocking motherboard, i5 3570k at 4.2ghz, and 8gb of 2400mhz RAM. The actual 780ti consumption here si really something like 240w.

The third link again is total system power draw including a 4770k at 4.8ghz, the same crazy motherboard as the previous link, and 16gb RAM. Again I doubt the card pulled over 240w.

Your system is not close to 850w. I'm guessing, with overclocks, 750w MAX as an overestimate.

 

[azzazel_99]

Ah i see that now. All i know is i can push each card individually to its max with not issues and both run perfect together in sli at stock but once i turn up the clocks is when the psu gives out. (or so it seems to be psu)

 

[tiny voices]

I'm still pretty confident it is not the PSU. Could be a weak link with SLI software and two overclocked BIOS modded cards, could be a voltage regulation issue (not a wattage problem), could be one card not playing nicely with the other one with custom overclocks (happens VERY frequently). It took me forever to get my 560s overclocked and happy together.
