Corsair RM1000x SHIFT ATX 3.0 Power Supply Review

Many PC Component manufacturers regularly making new computer power-supply and upscaling their product line with the power demand of upcoming next generation Processors and Graphics cards. But very few of them comes up with something different or innovative product.

Corsair with their new RMx SHIFT Series of power supply units, came up with a simple and innovative Side connector cable interface (moving the modular cable connection interface from back of the PSU to its side) making PC building much easier and giving a clean cable management option.
Today we are reviewing CORSAIR RM1000x SHIFT Power supply, a Fully Modular ATX 3.0 Power Supply delivering 80 PLUS Gold efficient 1000 watts of power for today’s most demanding PC upgrades.

Now let’s see what this Corsair RM1000x SHIFT PSU has for us.

Features

SIDE MOUNTED CONNECTIONS
An innovative patent-pending side PSU panel with modular connections lets you comfortably plug cables into the side face of the PSU, making it easier to connect and manage your cables than ever before.

ATX 3.0 CERTIFIED
The ATX 3.0 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, RMx SHIFT Series PSUs are formally certified for ATX 3.0 compliance.
PCIe 5.0 12VHPWR GPU cables included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.

CORSAIR TYPE 5 MICRO-FIT CONNECTORS
Fully modular, CORSAIR Type 5 Gen 1 micro-fit PSU cables, so you only connect the cables your system needs while taking up less space.

140mm FAN WITH ZERO RPM MODE SUPPORT
A low-friction, fluid dynamic bearing 140mm fan with Zero RPM mode support ensures your PSU runs cool while staying virtually silent when not under high load.

80 PLUS GOLD CERTIFIED
Steady power output at up to 90% efficiency, and Cybenetics-certified for lower power consumption, less noise, and cooler temperatures.

CASE COMPATIBILITY
The PSU and cables will fit in any PC case that supports ATX PSU format and is at least 210mm (8.3") wide. The PSU must also be accessible from the side when mounted in the case.

WORLD-CLASS SUPPORT
Our award-winning service means you can enjoy your gear worry-free.

Specifications

Package

Corsair RM1000x SHIFT comes in a securely packaged yellow / black coloured box with PSU graphics, Model name and features highlights on front and the back of the box.

Inside the box

Outer box contains RM1000x SHIFT PSU within a bag and a cardboard box includes Module cables, Power cable, cable-ties, Corsair interface cable, and User manual

Looks

RM1000x SHIFT PSU has new design with triangular air vents and innovative Side connector cable interface.

Inside

Corsair RM1000x SHIFT power supply board is build with the best quality components and uses all Japanese quality capacitors.

Corsair are uses their NR140P fan (140 mm, 12 V, 0.22 A) inside the power supply. According to Corsair, the fan blades are properly balanced to help reduce resonance at higher speeds. This is a fluid dynamic bearing fan which helps in prolong life and reduce noise.

Case Installation

Corsair RM1000x SHIFT power supply is installed inside a big case the Corsair 7000D along with Corsair Hx1000i PSU with modular cable connection interface at back side of the case.

One can clearly see, with the simple and innovative Side connector cable interface of Corsair RM1000x SHIFT power supply, resulted in a clean installation with great cable management and lets you comfortably plug more cables with your future upgrades.

Testing

Test system configuration -

Above high-power PC configuration is used to put the PSU in a real-world power handling scenario by running different GPU and CPU benchmarks.
And Corsair RM1000x SHIFT power supply easily handled many runs of high power consumption benchmarks.

Custom made DC Active dummy load PSU tester.

Unfortunately my PSU sample had some modular DC Cables issue. After contacting Corsair about this, they confirm that it is an isolated sample issue only and provided me a new set of DC Cables for review, which worked fine.

Load Test

To test the PSU on my Active load test, I have manually increased the load in Amps on 12v first rail, 12v second rail, 5v and 3.3v rail to simulate 100%, 80% 50% and 20% load. Since this PSU is having only single 12v rail, so divided the load in half on both 12v loads on my tester.

5V stand-by and -12V supply was left at a constant 0.5amp load throughout the test run.

Maximum theoretical load handling capacity of my tester is somewhat around 1500W, but due to MOSFETs safe operating area (SOA) characteristics and thermal load handling capacity of the heatsinks, this tester can handle Max 1300W. For safety reasons I have also installed a thermal controller which turn OFF the attached PSU if temperature exceeds SOA specifications.

During test the PSU ran smoothly close to 1080W of load, when tried to pull more the PSU turned itself OFF showing the proper working of Overload protection .

Pros

• Side connector cable interface
• Compact high-power CORSAIR TYPE 5 modular cable
• Fully Modular
• 80 PLUS GOLD certified
• Low noise fan
• 10 years warranty

Cons

• Nil

Conclusion

In our testing Corsair RM1000x SHIFT PSU performed good and to the mark of its power handling specification.

Being not a regular 1000W PSU, with Corsair RM1000x SHIFT PSU, the Corsair team came up with a simple and innovative side connector cable interface which makes this PSU stand aside in the PC power-supply market.

Bundled along with the PSU, new compact high-power CORSAIR TYPE 5 modular cable set makes this PSU fit in any PC case that supports ATX PSU format and is at least 210mm (8.3") wide .

Finally the New Corsair RM1000x SHIFT PSU with its innovative side connector cable interface design, makes it worthy of our PC TeK Reviews EXCELLENCE Award.
