5 out of 5 eggsPays for itself

Pros: At $0.15 / kWh, if your current PSU at its normal load gets you 84% efficiency, and this at the same load would get 92% efficiency, and you leave your system online 24/7, this PSU will pay for itself (plus an extra $80 that you save on top of that) within the warranty period.

Cons: Have to spend an extra $100 on a nice set of individually sleeved cables.

Other Thoughts: Several reviews (here and on other seller's sites) have complained about the power cord to the wall being "non-standard". They are wrong; it's a perfectly standard IEC 60320 C20 connector on the PSU end and a NEMA 5-15P on the wall end.

4 out of 5 eggsGreat Power Supply

Pros: Very Efficient. Reasonably quiet. Very well built. Good Looking Power Supply, for those who want to show off builds.

Corsair reliability. Their power supplies have a good reputation for trouble free use.

Handles 2 X AMD Radeon 295x2 cards, with power to spare.

Cons: The cables could have been a little bit nicer considering the price of this power supply. (this is a really minor complaint... almost feel bad making because the cables work just fine, but are not very flashy)

1 out of 5 eggsPower Supply with Little to no Output

Pros: Everything written in their specifications were pros.

Cons: Unfortunately, the power supply wasn't outputting properly so none of the pros could be verified.

Other Thoughts: Finally went to a shop to test out the power supply and other components. Everything checked out fine except for the new power supply. My best guess is that this is a day one problem since everything else I replaced checks out fine.

5 out of 5 eggsRelatively small for it's Power Rating

Pros: -Doesn't take up as much room as my previous, lower wattage PSU
-Lots of cables provided
-Virtually noise-free
-Talks to the H100i cooler with the supplied communications cable
-Fits in my RV-02E case with enough room to fit a H100i cooler below it

Cons: - Cables are flat instead of sleeved, so the are hard to route through the case

Other Thoughts: I suppose I could separate the wires and sleeve them myself, but it's kind of a hassle. Not enough of a problem to ding an egg, though.

Pros: Corsair Quality. I do not own this product but have similar Corsair power supplies, they are truly some of the best on the market.

Cons: BUYER BEWARE! This is actually 1300w when used on a traditional 110v power plug (normal USA house power). Power Supply requires a 220v (aka 220 line) for full 1500 watts.

Nowhere does it say this except on the sticker in the pictures where it says.

Total Power
1500W 115 - 240V
1300W 110V

Just thought I would point this out since it is somewhat misleading. The cost to run a 220 line in your house to run this at it's max power would cost as about half the cost of the power supply itself, if done by a professional.

1 out of 5 eggsDisappointing because of cables

Pros: Nice Specs and Technical reviews

Cons: Ribbon cables are left overs from the 80's and 90's and are a joke at best.

Other Thoughts: As already mentioned the ribbon cables are a joke. The cable don't bend, they obstruct air flow and are about impossible to stuff inside a ;large computer case if you have more than one GPU. I'm guessing they include these sub-standard ribbon cables to persuade you into buying there $100+ proprietary sleeved cables that Corsair makes. If you don't have the budget for an additional $100+ for extra cables on top of the $420-$450 you will spend on this power supply, you may want to consider one of the other powers supplies that Newegg sells.

I'm giving the power supply one egg because of the cables. The service from Newegg was great as usual, but my one egg rating is on the product itself. I can't really tell you about my satisfaction of the power supply itself because I haven't been able to to use yet because of the cables.

1 out of 5 eggsWhat a shame, such below standard cables with such a nice power supply.

Pros: Power supply has excellent specs and tech reviews

Cons: Accessory flat ribbon cables.

Other Thoughts: The cables that come with this power supply are a joke at best. The design of the cables are from the 1990's when were were concerned about computer case cooling and we went to round sleeved cables that air could flow around. Don't get me wrong they do offer round sleeved cable for an extra $100+ and even then it cost extra for the motherboard supply cable. If you're thinking about buying this power supply, plan on shelling out extra bucks for the optional proprietary cables to have decent cooling in your computer case. If you have multiple hard drives and video cards you won't have much choice because the ribbon cables take up so much space and obstruct the air flow.

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
