That looks like an absolute beast of a system you have running on that psu!

Now that's a HOT system, put intended in both performance and heat generation. Waiting on the R295x2 review to see how hot the Rad's actually got. You mentioned it in the video. I can't imagine having 2 of those cards in my system at $1600 or so apiece.

Awesome review, it actual;ly made me check my Corsairlink software to see my power loads in and out as I have never ever checked it lol. Just under 650 watts on my dual HD7970's on a Corsair Ax1200i. Yes probably an overkill where the psu is concerned but I need the high amps on the 12v as my old 850psu just could not cope with the crossfired cards, worked ok when not linked but would freeze in less than 15 seconds when crossfired.
A pricey investment but hell, like TTL said if you are going to spend a lot of money on graphics cards and whatnot then don't compromise on the psu.

I'm impressed with the way it destroys everything and with those kind of efficiency and ripple figures it is amazing but I don't know if I would every buy one. Say you had a 900D quad titan rig, the classic full loop overkill, wouldn't it be better to run two AX860's. It's significantly cheaper (260 vs 330), probably 2% less efficient, shorter so easier to package around radiators, would have a higher rating and should failure occur it would only take down half of your kit and leave you with a mostly operational system. The price per watt seems vastly disproportionate to Corsairs other PSU's of the similar quality.
Has the AX1200i been discontinued for this or will there be a second gen AXi series coming, not many people have stock of it at the moment.

Although the 900D has support for two PSU's in the bottom if you're going Quad-SLI you're most likely going to put a 480mm radiator in the bottom which would mean you could only fit a single PSU in the bottom unless you did some seriously ugly modding to squeeze a second PSU in along side the first 860.
In my own 900D I filled the bottom with a 480mm radiator and the top with another 480mm. With the cables for everything it doesn't leave a lot of room in the base, I could probably have squeezed another 240mm radiator in the bottom but it wouldn't look great, sticking a second PSU down there would be really difficult without it looking terrible.
I think the AX1500i would definitely be something someone who is buying four titans would afford without even thinking about it.
EDIT:// I just thought if you did stick a 480mm radiator in the bottom and then tried to stick two PSU's down there the 2nd PSU would exhaust heat straight in to the case as it wouldn't have its back bolted to the panel for exhausting heat outside. That would probably be an issue.

Wouldn't they sit back to back at the bottom and intake from each side of the case? Yeah I did kinda forget nobody put's rads in the front of 900D's, I was thinking you could have two 240's, a 360 and a 480 but yeah I guess that having the rad go right down behind the back PSU gains a little rad space in the bottom. My hypothetical 900D would be different
. And yeah after £5k+ I guess who cares about £70.JR
Really not got much of a clue with this PSU stuff but still a good watch anyway, haha love the shirt, I thought it was Brian from the car insurance advert, "You told her you have a red, Italian sports car, it is infact red, Italian hatchback, you're also a trainee plumber, not a trainee pilot, hope that helps!"
Edit: Video has just finished "ITS BRIAN THE ROBOT!" I guess I was right.

Corsair AX1500i Power Supply - Quite a beast. Big, expensive, well designed, all modular, great performance, quiet, and should last forever. Although I'm nowhere near overloading my present AX1200i, if I was in the market for a new PSU the AX1500i would be it.
In the past, fellow engineers and I discussed the criteria to be used in selecting power supplies. Suggestions came from several other sources as well. Online calculators don't use this method, but here's our suggestion:
If you are building a computer, or modifying a present one, you should know the system's components. Determine the maximum power required for that set of components as if all were operating at full load simultaneously. Granted, they will seldom be operating such, but you never know the exact load at any moment unless you measure it.
Select a PSU with that rated load somewhere in the "middle third" of its output power rating. In this case, the initial sizing range should be between 500W and 1000W.
Note this method is quite conservative by most standards, but there are several reasons why:
- The "middle third" is usually the most efficient operating range for any PSU, and it will cost the least to operate.
- It doesn't disrupt everything if you add a healthy load such as another graphics card, and should remain in the middle third. Unanticipated system growth can spell the death of equipment already operating at or near its maximum capacity.
- The unit should last forever, because you aren't operating it "balls to the wall" every time it is used. Excessive heat due to overloading is one of the best ways to shorten the life of electronic components.
One last comment: Electronic components, of which a computer is full, are very sensitive to PSU problems, whether they be poor regulation, ripple, or other. This unit is excellent regarding all measured parameters.
Even though this kind of money is a sizable outlay, think of it as an investment that will likely carry you well into your next build (or two), while protecting everything you throw at it.
Be sure your case is large enough to accommodate it and has good ventilation.
But don't take this as the only unit to buy, especially if your system doesn't need all that power. Select accordingly.

Hey guys,
( My english gramma is not the best but i hope you understand what i want from you)
I got 4 x Asus Matrix R9 290X Platinum
This Cards are Running by 250 TDP, i got 1000W with these cards if i calculate it right.
I want to Overclock them to max with Watercoolers. So i can set the Power Target to +50% so i will be @ 375W TDP. That mean 1500W under full Load.
Can i run this setup + mobo pumps and cpu and the crap on this Supply?
Or is the third and fourth Card never going to consum that much ?
Mfg
Damnati

What's the rest of your spec's mate?
