For the 1000W output power supply, it can output 1000 W, while it can draw 1000W/91% 1098W. So it still has some redundency.

I thought that efficiency is related with the difference between the load needs and the power that you need from the wall.

For example, if you have a load that needs 100W, and you have a PSU with an efficiency of 90%, then you get from the wall 110W.

you get a 91% efficiency with a rm1000i that use almost 95-100% of its power

I don't think so:

http://www.corsair.com/en/rmi-series-rm1000i-1000-watt-80-plus-gold-certified-fully-modular-psu

that must be wrong, i have one working at 91%

For the 1000W output power supply, it can output 1000 W, while it can draw 1000W/91% 1098W. So it still has some redundency.

it is actually higher than 1098, with mine the peak was 1200w for power in

If that is the case, then the efficiency of the power supply at 1200W for power in would be much lower than 91%.

i have a corsair rm1000i
is it enough for 6x 480 8GB Ref ? (1 rig)

With modded 480x I think it's enough, but take into account the efficiency of the supply.

In your example, imagine that you can mod your GPUS, and each modded GPU uses about 140w.

With a 6 gpu rig, you need about 140w x 6 + MOBO aprox 940W.

Well, if your psu is a 80+ gold, that comsuption gets you a 0,88 efficiency, because you are using near a 100% of PSU power.

Half of the power comsuption of your system, gets you a 0,99 efficiency.

In other words, you can save money in your power bill, if you try to use the half part of your PSUs power!

I hope you understand what I'm saying... and sorry for my english! Wink

Corsair RM1000i with 50% load has efficiency 93,18%
with 100% aprox. 91%
https://www.techpowerup.com/reviews/Corsair/RM1000i/5.html

Ok, then someone is wrong, Sad

The techpowerup page or the corsair page, this is what you can see in the tech specs tab for RM1000i in the corsair page:

I tested it with the similar result as in techpowerup review (230V).

Hey,
maybe someone can explain the hex values in that picture ? Maybe that leads us to this hashrates.

On the new H97 Anniversary ASRock Boards, if you have 3+ cards it wont boot unless you plug in the molex on the board. At least that was my experience, even with USB PCI-e risers.

I confirm that, I have a H97 Anniversary and mobo doesn't boot if you don't connect the molex on the board. I'm using it with 5 cards.

At the end my mobo is fried.

This morning I checked it because I couldn't connect via SSH ... and... Sad

The problem is like roitpls said, if you don't connect the molex in the H97 Anniversary, the mobo don't startup...

Now I'm thinking buy a H81 Pro BTC, if the mobo let's the user connect the cards without connect the molex...

Well, now waiting for a new mobo Cry

I run H81 mobos in all my rigs and have done it for years. I have never used the molex connectors because i have always used good quality powered USB risers.

Ok, I know it, and I readed a lot of information about not connect the molex to the mobo, ... but the problem with H97 Anniversary is that the mobo doesn't boot with +3 gpus if you don't connect the molex.. a message is displayed, and it's impossible boot.

Ok, then I will buy a H81 Pro btc. I expect the memory and cpu are ok!. 1st lesson! Undecided

Did you message say if you press the N button and it will boost and will never ask the same question again?

I don't remember if a pressed N, I don't think so. But I remember that the mobo couldn't boot, and I remember also that the screen doesn't show any messages about press any key to pass the check of molex.

I readed before about don't plug the molex connector, but as a said I couldn't boot the mobo. The rig was running about one month. Now, is too late to check if I can press the N key to pass the check. Embarrassed

To me it's really important to know if it's possible pass the check pressing N in that mobo, because I need to buy a new mobo and also in the future I think we couldn't find a H81 Pro BTC. Do you have a H97 Anniversary mobo without molex connected?

The cpu and memory should hopefully be ok, i have burned other kind of mobos in the past without killing something else.
