CORSAIR RM1000i 1000W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Active PFC Power Supply
  • eggxpert iconEggXpert
  • Owned For: 1 week to 1 month

Pros: I'd like to make a correction on the description I had before. Sorry for the error, but I had spent so many hours testing and writing down and remembering all the info I was getting from this PSU and the set up.

The "default" set up for this power supply is set to "multi ON" for multiple rails, which total are 12 rails @ 40A each. You would need the Corsair LINK software, which you can only get a copy from (just google Corsair LINK and it'll take you there directly), and once installed you can change it.
But giving that each port (6 to 8 and PSU) has its own rail, it's just best leaving it as is, rather than dumping all 83.3A on the few ports you may or will use. But if you're going for SLI or CrossFire set up? Then it would be up to the user to change for what he/she would feel most comfortable with.

During my test with the two 9800 GTX in SLI mode, I decided to leave it with the default setting of "Multi-ON" and the system was fully stable. I know have left it with the default setting for my personal main rig. Long time ago I only bought and use PSU with a single RAIL but things have changed for the best now.

Another great thing about this PSU that I left out was that the power cord is super heavy gauge, not sure if it's a 10 or 12 gauge but it's definitely better than the Supernova 750 I had, which I had to change it with the PC Power and Cooling's power cable, a massive 12 gauge. I really don't feel comfortable with anything less than 12.

Cons: None

Other Thoughts: Another thing to mention is that your motherboard comes only with two USB 2.0 headers, be prepare to lose one of the ports for the LINK cable to be connected from the PSU to the USB header.
I really didn't care much about this but some of you may still be using the USB 2.0 ports that came with your case. In my case, the 450D does not come with USB 2.0 ports so I didn't care much for them and definitely, I rather the USB 3.0 now. I don't consider this a negative for the fact that USB 2.0 should be obsolete immediately, I no longer have any USB 2.0 storage devices and USB 3.0 is backwards compatible with 2.0. So no need to keep using slow devices.

5 out of 5 eggs For SLI, Tripple SLI and CrossFire system. Enough power to deliver 07/26/2015

This review is from: CORSAIR RM1000i 1000W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: -7 year warranty (newegg description says 5)
-Switchable from Single 83.3A rail to Multi 12x 40A
-Real time efficiency exceeds 80%
-1st Generation Link cable included
To name just a few.

Thank you Corsair and Newegg for letting me review this PSU, and for that I did prepare and got as much hardware as possible to push this as far as I could go.

Testing first with my main system (GTX 960 + 4690K 800mhz to 4.50ghz, SB-Z, 4x 140mm + 1x 120mm fans, 4 mechanical HDD and 1 SSD).
For power consumption I used an Electric Power Meter and also the Link software.

On Stand-by: 1W
During booting (fluctuating): 160W-110W
PSU temperature was 27.8.
Idle power: 96.2W in - 76W out
82.50%-84.75% efficiency
Both Link and Power meter right on the dot.

For system running full power I used the fallowing stress test programs: Prime 95 for CPU and Furmark for GPU.

4690K running at 4.50ghz @ 100% full load with Prime: Power consumption was 195.8W in - 176.0W out with an 89.91% efficiency. Very impressive.
Fans turned on at full 12V (or full speed) system jumped to 225W in - 196W out for a 90.14% efficiency.

GTX 960 at 100% full load with FurMark 1.16.0:
356W in
328W out
For a 91.81% power efficiency. A jump of 131W from CPU at full load to GPU's power consumption at full load.

Temperatures with all fans at full speed as fallow: CPU 85-94c and GPU at 60C. Room temperature was at 77F (25C).

When I received the invitation to review this PSU, I decided to use my 2nd system as well and decided to buy a 2nd GeForce 9800GTX (got one on auction site for $21.99 shipped) and run SLI on that system, but runs on a Core 2 Quad Q6600 at 3.0ghz. (334x9) with a 4:5 ratio.

Even with less fans and less hard drives, system used 515W, efficiency was well above the 85%.
Stress testing the 9800 GTX with FurMark made the turbine fan run at full speed and it was extremely loud.

So, after doing my test and seeing power usage and efficiency, I'm fully convinced that if anyone that will build an SLI, tripple SLI or CrossFire system, this is the power supply to get, the efficiency is better at 50% and with today's high end card running at over 150W TDP, this PSU will handle such set ups, it runs cool, fan never came on and PSU reached a 36.1C.

For those running a single card, the 750W would suffice. I see now that it's best to run a PSU with its 50% efficiency for better power consumption and delivery to your system. Consider a 750W if system consumes 300W-350W.

Cons: None.

Other Thoughts: This PSU shouldn't be in the "Gold" certified section, it's at least a Platinum and close to Titanium class.

The "LINK" software is great, not only can set the PSU from a single to multiple rails, but also the PSU's fan can be change from "default" to a fix %, percentage starts at 40% to 100%. At 100% and 1488rpm, the PSU is LOUD, a more suitable speed to noise ratio is 50% (872rmp), but better leave at default.
The LINK software also monitors (but not able to change any parameters) other hardware parts in the system. What is annoying is that my GTX960's fan don't spin till it reaches 50c, so the LINK software is always showing the 960 in RED.

Efficiency was superb, hitting as much as 92% and lowest was 82.50%.

Although lower percentage does not mean watts being wasted, it just means less watts input, less watts output. And the higher the the higher the efficiency output.

Overall, you'll be please with this unit, it's highly efficient and the build quality has surpassed previous generations and could definitely very well be better than most 1000W PSU on the market.

5 out of 5 eggs Very fast Reader and good writer. 07/23/2015

This review is from: Mushkin Enhanced Reactor MKNSSDRE256GB 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD)

Pros: CrystalDiskMark 4.1.0 x64 (C) 2007-2015 hiyohiyo
Crystal Dew World :

Test : 1024 MiB [C: 19.0% (45.4/238.1 GiB)] (x3) [Interval=5 sec]
Date : 2015/07/12 4:30:17
OS : Windows 8.1 [6.3 Build 9600] (x64)

As you can see, the speeds are pretty much on par with the ones in the description. It's great and inexpensive drive, you get amazing "READ" speeds, although the "WRITE" speed isn't that amazing but good enough, considering that the drive is mostly for Windows and for "STORAGE" I got a WD Black SATA 6 which is the best mechanical drive one can ever own as well.

I'm going to get the 512GB and clone it as I will be using it for storage as well, considering that the 512GB version does a 100MB/s more than the 256GB version.

Another suggestion would be to get a Corsair Slider 128GB USB 3.0 flash drive and use that for temporary files, that's another fast drive as well, doing 120MB/s Read and 75MB/s Write, not bad considering it's only $29.99.

My computer boots up really fast, @ 560MB/s, it's exactly what I wanted, a fast reading drive to boot up Windows in less than 12 seconds and this drive delivers.

Cons: None.
