Review corsair rm850i

Corsair leader in the manufacture of power supplies, boxes and RAM memory. He has shipped us one of his new 80 PLUS Gold Efficiency Certified RMi Series supplies and they offer extremely precise voltage control, virtually silent operation and a fully modular lead set. Specifically, we have the Corsair RM850i model capable of holding an SLI or dual processor cards such as the Titan X.

We thank Corsair Spain for trusting the product for its analysis.

Corsair RM850i

Corsair makes an excellent presentation with a large cardboard box. On the cover we find an image of the power supply, the name of the model and and the power of 850w. Already on the back it indicates all the most important specifications and features.

Once we open the box we find another standard cardboard box that houses the power supply and all its accessories. I detail the content of it a little better:

• Corsair RM850i power supply. Modular Cable Kit Set Instruction Manual Power Cord and Screws for Installation

We have a power supply with a standard ATX design with quite special dimensions: 150mm x 86mm x 180mm and a weight of 1.98 kg. Gray and black colors predominate, giving a very minimalist touch.

Among its characteristics we find the 80 PLUS GOLD efficiency certification, which guarantees excellent efficiency. The core is manufactured by the prestigious CWT brand with Japanese capacitors and compatible with Intel Haswell and Skylake platforms.

To highlight its unique power of 70.8A that make a maximum power of 849 w. In the upper area we find a silent 135 mm fan model NR135P self-regulating (PWM) and with semi-fan less technology that allows the fan to be stopped at low load and only activate when it is necessary. To finish with the premium components, it has 100% Japanese capacitors at 105ºC to give greater stability and long-term reliability.

As a highlight we have to talk about Corsair Link Digital allows you to easily monitor the performance of the power supply, toggle between single and multi-rail mode, and directly control the fan speed from your desktop.

The wiring system is completely modular, as we can see in previous images, it includes an LED to indicate the status of the power supply, the connections for the wiring and the connector for Corsair Link.

It incorporates a wide variety of cables, all meshed and with very good connections. I would have liked them to be more flexible, but for this range it is great. The game is made up of:

• ATX connector 1 EPS connector 2 Floppy connector 2 Four-pin peripheral connector 8 PCI connector 6 SATA connector 10

Test bench and tests

TESTING BENCH
Processor:	Intel i5-6600k
Base plate:	Asus Maximus VIII Gene
Memory:	Corsair PLX 3200 mhz 16GB.
Heatsink	Heatsink as standard.
HDD	Samsung 840 EVO.
Graphic card	Asus GTX 780 Direct CU II.
Power supply	Corsair RM850i

To check at what level our power supply works, we are going to check the energy consumption of its voltages with an Asus GTX780 Direct CU II graphic, with a fourth-generation Intel Skylake i5-6600k processor over another high-performance source such as the Antec HCG -850W.

WE RECOMMEND YOU Corsair Concept Orion is an experimental box with Capellix lighting

Corsair link

It is the desktop application that allows you to monitor and record fan speed and power consumption, as well as control fan speed and configure + 12V rail operation.

Final words and conclusion

---

This is the first contact with the Corsair RMi series and it couldn't have left a better taste in my mouth. Excellent core, semi fan less fan (semi passive), corsair link and 80 PLUS GOLD certification.

After our tests we have been able to verify that it is the power supply that has lowered consumption in our equipment. We have a 5-year warranty and 24/7 lifetime support. He splashed for Corsair!

I see it as a candidate for an enthusiastic team looking to mount two graphics cards without spending a kidney (it's around 150 euros) or a dual-core graphics card. We can confirm that it is one of the best units on the market and if it does not have the titanium certification, it is because it has not lacked much.

ADVANTAGE	DISADVANTAGES
+ DESIGN AND COMPONENTS	- CABLES COULD BE MORE FLEXIBLE.
+ SEMI-FANLESS FAN
+ MODULAR CABLE MANAGEMENT.
+ 80 PLUS GOLD CERTIFICATION
+ GOOD OPTION FOR CONFIGURING TWO GRAPHICS CARDS.
+ 5 GUARANTEE.
