2 out of 5 eggsGood, when it works.

Pros: Provides lots of power when it works.

Cons: I used this in my main system since the end of May of 2014. Suddenly I started having random shutdowns when I'd be playing a game or using a distributed computing app that maxes out the unit. It worked fine for about 3 months with no issues and randomly these events started. Decided to RMA the unit for a replacement. Put in an old 1350 watt Enermax and that solved the problem. But I still want to use this unit, so I'll wait for the RMA to be completed.

Other Thoughts: When it worked, it was a great power supply, but now I have to RMA it. I realize that you can't get everything 100% perfect all the time, so I'm going to give Corsair the benefit of the doubt here. I'm not a big fan of the flat cabling, I prefer the smaller round ones.

5 out of 5 eggsWell worth investment

Pros: Supplies power to three AMD R9-295x watercooled GPU cards (6 total GPUs) and an i7-4770K all running at 100% utilization 24 x 7 for protein folding simulations using OpenCL.

Power draw ranges between 1,370 and 1,420 as measured by the USB connection from the power supply itself and efficiency is between 93% and 95%, also measured on the same connection. Has been running for 3 weeks without any issues. Even running at close to 95% of the power supplies rated 1,500 watts, it produces a surprisingly small amount of heat.

Being used in a Chenbro RM-413000 server chassis/case (4u) - fits perfectly.

Cons: Non-standard connection on the power supply connection, which forces the use of Corsair's power cable. The cable should be another 12 to 18 inches longer, which would make it much easier to choose the placement of the server within a 45u rack. Either that, or have the option to purchase a longer one.

Other Thoughts: Unsurprisingly, the power supply is heavy, so think carefully about the case you're using and if it can properly support the weight. Not a con, just a caution.

Suggestion for Corsair: Update the monitoring software to provide a configurable log-file for user-selected data fields, like power draw, efficiency, etc over time. The overall application could be streamlined with fewer graphics and more focus on obtaining access to the data it creates, either pure text file or XML

4 out of 5 eggsCrazy stupid powerful

Pros: It's a true single 12V rail. Other supplies like the Lepa may have 1600 total watt output, but it's spread across a half dozen rails which doesn't help you if you have a high overclock GPU burning 600W of power by itself.

This one comes with a real USB plug on it, unlike the AX1200i that forced me to use one of my mobos USB headers. I just ran a USB cable through a hole in my case and plugged it into an actual USB port.

All of the specs on this thing are top notch. Titanium efficiency, full modular, etc.

Comes with more cables than you'll ever need. Even comes with a super long CPU 8 pin-er for giant cases. could probably run quad GPU's with 10 hard drives and still have leftover cables.

Didn't need to use the cables that came with it. AX1200i cables that were already installed in my case plugged in fine (except CPU one due to length below)

Cons: There needs to be a blackout mode for this thing. One LED stays green while the PSU is on, another LED obnoxiously blinks red and green when it's connected to the software. Give me an option somewhere to turn both LEDs off.

Corsair reversed the positioning of the 8 pin connectors and the 6 pin connectors vs. the AX1200i this replaced. This means you might need to re-wire a bit if you're upgrading from the 1200i.

I wish it came with 2 of the 800mm 8 pin CPU power cables. A lot of high end mobos will have 2 CPU power sockets on them for insanely high overclocks.

Other Thoughts: It's very likely you don't need a power supply this big. If you're only running a moderate CPU overclock and 2 GPUs, save your money and buy a smaller (<1000W) power supply. IME people hugely overestimate how much power supply they actually need.

Corsair has amazing customer support. My AX1200i had some whine and they did a cross ship free replacement no problem.

Some people might complain that the power cables are ribbon-style instead of sleeved round-style like the AX1200i. I don't really care since I'll make whatever ties fix everything.

It's a couple inches longer than the AX1200i. My case has tons of room so this wasn't an issue.

It doesn't use the standard wall outlet'll have to use the one they provide.

5 out of 5 eggsFor Overclockers

Pros: I do a lot of vga overclocking with my 2 kingpins and this psu is by far the best I've ever owned. I replaced a seasonic 1000 & 860 with this one for the needed space. The price tag is high but you get what you pay for. Simply the best..

Cons: The only con is of course the very high price, Be sure you have the space in your case because this is the biggest psu I've seen..

3 out of 5 eggsGood quality, bad software

Pros: Lots of power. it can power just about anything. Has been running 24/7 since I got it.

Cons: everything is big, from the box to actual PSU. you will have a hard time to work with it if you have a mid-tower case.
Don't even bother with the software, it does work. I tried countless times, but can never get it to work.

Other Thoughts: While the titanium efficient is great, it will not save you much unless you have it on 24/7. There are other big wattage PSUs offer better ratio.

4 out of 5 eggsHardware so much

Pros: Quiet, Powerful, Plenty of cables.
No problem with installation. Fired right up with no hardware glitches.

Cons: Software doesn't want to work. Maybe because I use Windows XP, but can't tell for sure...haven't found specs for software on web site. You have to cdrom included. Keep getting NET framework error when I activate the Link software.

Other Thoughts: Software is not necessary for use of power just adds bells and whistles. Unit is replacing a 1000 watt installed 13 years ago.
It would have gotten 5 stars except for the software problem...if it last as long as my last power supply I'll be ecstatic and give it 5 stars.

5 out of 5 eggsWOW

Pros: Silent, NO Coil Whine, Efficient, Just Oozes nice construction. Love this thing so far.

10/10 @ jonnyguru not an easy task

They put a mini-usb-B jack on the psu for the usb/link interface and ditched the tiny-connector-to-huge-usb dongle cable that the 1200i came with. Great move for reducing cable management clutter.

Cons: NONE.. (lil pricey, but no regrets)

Other Thoughts: Its pretty long, makes the 1200i seem like 'normal' sized psu.

I like the non-braided flat cables shipped with it, as they are easier to completely tuck and hide. But may not be the case for everyone.

1 out of 5 eggsSweet Paperweight

Pros: Looks pretty nice. Probably works really well, assuming you CAN use it.

Cons: Came packaged with a European power plug, despite being the NA version. Corsair's customer service is a joke.

Other Thoughts: I'm almost certain no one works in Corsair's customer service. My ticket has been completely ignored. Their phone hours are atrocious. When I have had a chance to call, I get patched through to the black hole of their phone mailbox. It seems like a simple fix: send me the CORRECT power plug for the product I ordered and I can be on my way. Apparently I am wrong, though, and I am left feeling like a less-than-valued customer.

It seems the only option I have at this point is sending it in for an RMA through Newegg, which I would rather avoid for such a trivial issue (full return for something as small as missing one cable? What a bummer!) As such I will

Manufacturer Response:

Hello Zach,

Thank you for the review, we're sorry for the inconvenience caused by the EU plug. Please give us a calll at 888-222-4346 so that we can investigate the issue and replace the plug with the NA plug.

5 out of 5 eggsA serious PSU, maybe the best 1500W for PC in the world.

Pros: Digital, incredibly efficient + powerful + quiet. A true zero-noise PSU. The fan only turns on when I put the rig under a real load, and my rig is a true monster. Even then it's a slow speed. The only time the fan kicks on max speed is during powerup (part of its POST) and immediately goes to a low and then a zero speed state.

Cons: The ribbon / flat cables suck bad. They remind me of black versions of rigid ribbon cables from 1980 floppy and other stuff. MUCH more important than looks though (to me) is they're simply a PITA to deal with.

Very difficult to route making it hard to get them where you need, especially in giant case like mine (Corsair 900D) and near impossible to do a clean organized set up. The quality of the PSU itself (so far) deserves 5 star regardless of the cables. But, Corsair should take a page from EVGA "for cables ONLY"... the cables for Super Nova 1500 are awesome, the SuperNova PSU itself is [ proven unreliable ] and should be avoided though. That thing is the reason I needed another PSU and bought the AX1500i.

Other Thoughts: Make sure you have room for it. 225mm x 150mm x 86mm. The height and depth are fairly standard out of necessity (bolt patterns) however the length is on the extreme end.

I run 2 PSU (other is a Corsair HX1050) in my 900D case. The 900D is massive. Even with one of my rads (240XTX) mounted in the bottom toward the front, glass side and my bleed tube on that rad there's plenty of room for the AX1500i. Smaller case owners - definitely - need to measure before purchase. Don't get surprised by it after it shows up.

Back to the efficiency of the AX1500i. I run triple D5 pumps and several misc with my HX1050. The AX1500i is dedicated to running 2xTitan, Asus R4E, i7-3960X, 32g G-Skill 2133, 4xSSD, 2xHDD(storage stripe). When putting this beast under extreme SLI and CPU (Intel Burn Test) loading, the AX1500i fan turns on, at a slow speed. This is absolutely amazing. I have 18 noise blocker multi frame fans, 3 pumps all on medium, so overall the system is essentially silent. Because of that, a loud PSU ramping up to carry heavy loads makes a big impact.

The SuperNova (when it was working...) cranked up like a jet. The AX1500i is so quiet under load you can't even tell (at all) if the fan is spinning or not (it's usually not) unless you physically look at it. If the AX1500i holds up this has got to be the finest, real 1500W PC-PSU in the world. Time will tell. I'll post back in 6 months or a year about how it's doing.
