didn't mean to steer anyone wrong I was told it wasn't going to be in till June I'm glad I was told wrong didn't buy anything.

meanwhile I have the ax1200i and the R9 295X2 hooked up without any problems I connected 2 separate power connectors just to be safe b/c I didn't feel like looking up power stuff I don';t know how to upload pictures I will put something on youtube shortly prob this weekend

A lot of folks have 15A circuit breakers running at 110v. 1500w/110v = 13.6A. If by chance you do run it at peak, make sure nothing else is on that circuit!

I'm all in for beefy power supplies. I want nice clean, efficient, cool, and quiet power for my overclocked SLI rigs. Sure you can go with lower rated power supply. It will be less efficient meaning it runs hotter, and now that cooling fan is running at high RPM to keep it cool making it noisy. Also unless your incoming power is a beautiful 120 V sin wave your power supply is going to struggle to keep your system at spec voltage without a bunch of ripples. As far as computers getting more power efficient, that is true, but then again now we have the options of trying to drive multiple 4K monitors and you are not going to drive those effectively with low power solutions for a long time.

Um, no it is NOT available. Not one website has it in stock yet and Corsair is showing "SOLD OUT".

LatiosXT

It is available.

Everyone just bought the stock before you got to it.

This is nice, I won't argue that point but why are PSU manufacturers concentrating on higher rated capacities when everything else in the market is continually lowering power consumption. For a 1500w PSU max efficiency is 750w and in 2 years or less it will be very difficult to bulk a PC simply to hit that number.

I think the big thing is that 94% efficiency at 50% load, when was the last time your PC actually got near maxing out your PSU? Most of the time they barely run above idle, and for that you want the best efficiency possible. Less money to the power company, more money to %online game vendor of choice% at the end of day.

"Most of the time they barely run above idle". My point exactly. Since the max efficiency is ~50% why wouldn't a smaller PSU be more effective? PC consumption of ~100-200w would recommend a PSU of about 300w.

This isnt for that kind of computer.

This is for heavy OCers and Muilple GPUs....

Enigmatistical

Even 4-way SLI rigs in 3-4 years time won't consume more than 100w each. Now that $450 7 year warranty PSU is obsolete. If you're not running a PSU at max efficiency you're simply not getting your money's worth. 1500w is a waste and that's why it's warrantied for 7 years. Corsair knows you'll replace it well before then.

i beg 2 differ, 2x295x2 reuires a 1200watt PSU, BARE MINIMUM.

Additionally, Smart techs NEVER run PSUs over 80% load.

At 50% load this power supply is more efficient than a 750W power supply at 100% load. Using just 797.9W of power compared to 862W. In fact, it will be more efficient at any load. It will also be much more stable. Things I'm looking for in a performance build.

I think I'm having trouble counting...

10 pci-e + 20 sata + 12 4-pin = 42 connectors.

But excluding the floppy, EPS & ATX connectors, I only count 16 connectors.

Is it me, or is something not right here? Are there more connectors on the long side that we can't see?

avatar

LatiosXT

The cables you attach have multiple plugs. And you probably can't attach them all.

avatar

The Mac

does it have the 28A requirement per PCIe connector for 295x2?

avatar

LatiosXT

The PCI-Express spec, as far as I can find, only allows a maximum of 150W for 8-pin. That's just above 12A per connector.

I mean, I guess each one could draw more since if you're using 16AWG wire, Wikipedia says you can draw 18A per wire maximum if the insulation is rated for 90C. They don't have anything lower though, and lower rated insulation allows for less amps.

According to Corsair it does also since its single rail you don'g have to work about getting connectors correct I have a AX1200i and have a R9 295X2 on its way today

avatar

The Mac

its less about the rail, and more about wire/connector itself.

If you draw 25A through a connector rated at 10A, its going to melt.

Just so everyone is aware I have confirmed with Corsair this will not be available until June

Don't know who you talked to at Corsair supposedly, but that's wrong. It was temporarily out of stock yesterday, and in stock as I'm typing this comment. Here's a screenie:

Thanks percy615 - very useful information! That gives me time to save up a few extra pennies ;)
