Arrow Corsair RM750x 2018 Review

Quote:
Corsair is a company that likes to keep their products up to date. Not long ago, they replaced their venerable AX1500i with something even more powerful and awesome. They're at it again today with a freshened up version of their more budget friendly RM750x. Let's find out what's different.

the new layout looks clean and neat compare with old RMx, but the white edition still the old design?

The white edition with the individually sleeved cables is the old design. That was launched a few months after that last version of the RMx, but took a while for reviews to hit the web.

There will be a new white version of the RMx based on this new wireless platform, but they won't have individually sleeved cables. Instead, they have regular sleeved cables, but in all white (with white sleeves).

Will there also be an RMi refresh?

The platform looks rather similar to BitFenix Whisper M. Performance is flawless. Good job!

What about a fan? It looks it still uses a rifle bearing fan, mhm, is it at least some specific long-life-high-lubricant-capacity one? Is the MTBF spec of 100k hours for a fan or in general for the PSU?

With an MCU-controlled semi-fanless mode, it won't be spinning very often.

What is MCU, exactly? And I know, as far as I recall it is spinning depending on the power consumption and that it starts spinning...at 50% I think? Honestly with my planned rig t should not spin at all, but with such fan (again, the question is what is the life expectancy of that rifle bearing fan) it is merely a time bomb.

MCU = Micro-Controller Unit

MCU is the digital control unit which regulates the fan speed. It does so based on load conditions of the unit as well as temperature. Thus the fan isn't going to turn on if the unit is "cold" inside and below a certain load threshold but let's say you're running the unit at 10% capacity but the room is 50C? The fan will turn on to make sure the internal components stay cold.

While you could program an MCU poorly, in general MCUs offer you more granular and better control over a fan profile than a normal diode based control method.



Also, looking at a rifle bearing fan as a timebomb is a pretty pessimistic and poor representation of what a rifle bearing fan is. If you really think it's that poor of an option, why do you think Corsair is going to cover the unit with a 10 year warranty?
