Introducing the New RMx Series of Power Supplies

 

This month, Corsair introduced the new RMx power supply series. The RMx ostensibly replaces the RM in Corsair's power supply line up. The RMx features the same 135mm rifle bearing fan as the RM, with a "Zero RPM" mode that keeps the fan from spinning, therefore completely silent, at loads under 40%. The RMx is 80 Plus Gold and is fully modular, but other than this the RMx has quite a few upgrades over the RM.

The RMx features all Japanese capacitors, rated at 105°C. This upgrade allows the PSU to run at full load, continuously, in environments as high as 50°C. For this reason, we've increased the warranty for the RMx from five years to seven years. The RMx product line has also been expanded to not only include 650, 750, 850 and 1000W varieties; but also a new lower wattage 550W unit.

Due to the limited functionality of the Link software with the original RM Series and the neccessity of a bulky dongle, the Link functionality has been removed from the RMx. If the user wants the ability to monitor their PSU as well as control the fan and how many +12V rails their PSU has, these features are available in the RMi power supply series.

The cable set for the RMx is much like the RMi's. They utilize the new “Type 4” cables.  The 6-pin cables (for SATA and peripheral power) are identical to the Type 3 cables used previously (HXi, RM, etc.).  But the 8-pin cables (for ATX12V/EPS12V and PCIe) have added capacitors to help reduce the ripple noise on these leads.  Furthermore, the Type 4 24-pin has an additional four pins, as well as the added capacitors.  These extra leads are sense wires that allow the RMx to sense the voltage at the load and adjust accordingly to improve voltage regulation.

Today’s high-performance CPUs and graphics cards all require power to be supplied over the +12V rail, which means that any PSU worth considering needs to be able to deliver the majority of its power on the +12V rail.  The RMx Series PSUs can deliver all of its available power via the +12V rail, which make them ideal for high-end gaming PCs with single and multiple GPUs.

All of the power supplies in the Corsair RMx Series have the necessary protection functions to ensure trouble-free operation, even in extreme conditions. Below is a list of the included protections:

    • Over Current Protection (OCP):  Shuts off power if any rail is overloaded beyond a safe level. 
    • Over Voltage Protection (OVP): Shuts off power if voltages exceed specification.
    • Under Voltage Protection (UVP): Shuts off power if voltages drop below specification.
    • Short Circuit Protection (SCP):  Shuts off power if a short circuit is detected.
    • Over Temperature Protection (OTP):  Shuts off power if temperatures exceed a specified value.
    • Over Power Protection (OPP):  Shuts off power if the total output power exceeds a safe level.

    The RMx series power supplies are currently available in the U.S. exclusively at Newegg.com. Outside of the U.S., the RMx is available at your favorite computer component retailers.

      統一教会だから何をやっても認めない すばらしくカルトチックな記事です カルト脳全開といったところだね アメリカじゃSeijin君のことはexaminer.com topix.com 他でも記事にされています 統一教会だからというバイアスなしでダメなものはダメ 良いものは良いと云えなければダメダメ記者と新聞もどきでしょう そういえば統一教会に関する良いことは書かない それが藤倉のポリシーでしたね すばらしい英語力でSeijin君の記事でも読んでくださいな Dallas, TX) Salutations from Dallas Mayor Mike Rawlings will be read at the Faith, Freedom and Family Rally at Dallas City Hall Plaza at 10:00 a.m. Monday, Jan. 2, 2012. Mayor Rawlings' welcoming raermks will be read by talk-show host Ester Davis, who joins local civic and religious leaders, as well as Japanese-Americans wearing kimonos, to welcome two university students who have embarked on a 2,300-mile bicycle ride to raise awareness of religious freedom in Japan and other countries. The cyclists began the tour at Atlanta's Gold Dome State Capitol on Dec. 15, 2012. The keynote speaker at the rally will be Bishop Harold Edwards, leader of the Church of the Living God in Dallas. Organizers say the goal of the tour is to raise public awareness of the fact that since 1966 more than 4,000 Unification Church members in Japan, as well as significant numbers of members of other faiths, have been abducted and confined for months or years of psychological and physical abuse in an effort to break their faith. Houston resident Mrs. Taeko White will recount her experience of abduction and deprogramming in 1981. Jeffrey White, 24, her son, will read a tribute to his mother. Mr. Luke Higuchi, a Japanese survivor of abduction and forced conversion, will report his experience at the rally.Advertisement Mr. Seijin Tranberg and Mr. Joshua Wildman, both 22, began their Freedom Ride on December 15, 2011 in Atlanta, the birthplace of the U.S. Civil Rights Movement, under the banner of Faith, Freedom, and Family. Prior to starting their tour, Mr. Tranberg briefed twelve congressmen at their offices on Capitol Hill. All 12, representing states from Georgia to California, expressed support for persecuted religious people of the world by signing Mr. Tranberg's route map and posing with him for photographs. Mr. Tranberg also is calling the rally to raise awareness of the rights abuses against religious minorities the world over, including Baptists in Russia, Coptic Christians in Egypt, Bahai's in Iran, and many others. Representatives of several persecuted minority groups, including African Christians, Hindus, Muslims, and others will be on hand. The rally has sparked supportive comment from local leaders. Rev. Don E. Peavy, Sr., Associate Minister, New Vision Christian Church in Fort Worth has written: We wish Seijin and Joshua Godspeed in their momentous adventure to spread the Gospel of the common bond we all share as children of God. Their mission is particularly critical at this moment given the mass killings in Nigeria on Christmas Day and the religious insensitivity and intolerance which continue to keep far too many people from living the abundant life for which Jesus the Christ came into the world.
