Corsair RM750 750W 80+ Gold Modular PSU Review

Introduction - RM in 2019

A lot has changed since Corsair released their original RM series of power supplies. Yes, the old series was still 80+ Gold Certified, but should all know that there's more to PSUs than raw efficiency figures. 

For starters, pricing has decreased, with Corsair's new RM750 750W unit costing $109.99 in the US and £99 in the UK. In the past, 80+ Gold rated components were a lot more expensive than this, especially for high wattage, fully modular units. 

Another factor where Corsair has innovated in recent years is in voltage ripple, with Corsair's more recent PSU designs providing high levels of voltage stability, as well as high levels of efficiency. This level of stability is what has kept Corsair as one of the PSU market's top brands, especially within the high-end PSU market.   

Perhaps the most important change is in PSU warranties, with the new 2019 RM series offering users a staggering 10-year warranty, whereas the original RM series only offered users a 5-year warranty, which for the time was above average in terms of length. PSU makers now show a lot more confidence in their units, especially on their high-end lineup, giving consumers a support period which will likely outlast every other component in your system. Have you ever used a single PC component for over a decade?

Unboxing

With Corsair targetting their new RM series as a budget entry point into the high-end PSU market, we can understand why some of the premium packaging elements of the RMi series have gone by the wayside with this release. 

No more premium nylon bags for your modular cables. With the 2019 RM series, you now have your cables neatly stores within a box. While this is a downgrade, it is preferable that Corsair lowers their packaging costs to the component costs of their new RM series power supplies. To achieve lower pricing, cuts have to be made, and packaging is the logical place to make these cuts. We can also note that Corsair's 2019 RM series power supply comes within a plastic package, rather than a neat PSU-sided fabric bag. 

Even with these packaging downgrades, it is hard to say that the new RM series is in any way badly packaged. The unit is well protected with foam, and the unit's modular cables are well stored. All that we have lost here is a little bit of the unit's premium feel, which makes sense given the lower pricing targets of the RM750.

Power Cables - How many of each are available?

The RM750 ships with everything you will need to build a high-end system of pretty much any sort. Need extra CPU power, have two EPS connections, multiple GPUs, here are six PCIe cables. Let's face it, who needs sixteen SATA connectors? Not many PCs need more than 850W of total power, but pretty much regardless of your configuration, are unlikely to need more cables than what the AX850 can supply. 

- 1x ATX Power Connector (24-pin)
- 2x EPS/ATX12V Connectors (8-pin/ 4+4-pin) 
- 6x PCIe Connectors (6+2-pin)
- 12x SATA Power Connectors (Straight + Right Angled)
- 4x Peripheral/Molex Connectors
- No Floppy Adapter


Replacement Cables? 

Corsair has confirmed to us that their new 2019 RM series of power supplies use their Type4 Gen4 cables, replacements for which are purchasable online. Replacement cables will also offer users inline capacitors, which will enable improved ripple performance over Corsair's stock cable kits. 

Our unit comes from an early batch and contained both Type3 and Type4 cables, this will be addressed in future PSU revisions. Note that Corsair Type3 and Type4 SATA/PATA cables are identical, so the mismatch is meaningless in this instance. Most retail units should lack this minor labelling error.

Pricing

Corsair has provided us with the following pricing information for their new 2019 series of RM power supplies. In the case of the RM750, the new 2019 RM series is $20 cheaper than it's RMx series equivalent. For the 850W model, this price difference increases to $30.

The 2019 RM series has been positioned as an affordable entry-level 80+ Gold rated power supply. The pricing below comes from Corsair's official RM series reviewers guide, which outlines the specifications, pricing and features of their RX series of PSUs.
