difference betwee:

Corsair RM750x 750W PSU 80+ Gold Fully Modular

and

Corsair RM750 750W PSU 80+ Gold Fully Modular

what is the difference?

[Morgan MLGman]

The RM750x is better internally than the latest RM750 AFAIK. If the price difference isn't too big, I'd get the 'x' one.

According to Vendetta_86 on reddit:

 

Corsair's new RM (without the "x") line consists of three members with capacities ranging from 650W to 850W. All of them are more affordable versions of the corresponding RMx models, which is expected to be updated in the near future to be fully compatible with the latest ATX specification.

The RM units mostly use Chinese Elite caps, which are of decent quality, instead of the superior Japanese Nichicon and Chemi Cons and employ Hong Hua rifle bearing fans instead of Corsair's more-powerful NR135L. These changes might not be welcome by PSU enthusiasts, but the fact is that they don't seem to affect the product's lifetime since Corsair provides exactly the same warranty period (ten-years), in both RM and RMx units.

Two new features of the RM units, which are not present in the RMx 2018 line, are the increased efficiency under very light loads (2% of the max-rated-output) and support for Windows 10’s new Modern Standby mode that enhances boot speed and connectivity for your PC. The S3 sleep state usually takes anywhere from 7-15 seconds to turn on depending on your PC's configuration, while the Modern Standby function promises to bring that to reliably under five seconds.

Finally, the RM units don't use cables with in-line caps, as the RMx do, which might help in cable management since the cables are less rigid, but the ripple suppression is not up to the excellent levels of the RMx units (still it is quite good though).

All RM models come with two EPS connectors, so they are fully capable to power high-end mainboards with increased power needs.

The RMx has Japanese caps and a better fan

The RM has Chinese Elite caps and a slightly worse fan.

The RMx released in 2018, the RM in 2019

Both are good PSUs, but if they are the same price or within 25 shekels I'd get the RMx

Uh, you've been misinformed. You only need a single 8 pin for most overclocking.

 

The extra +4 (or even +8 on ultra-high-end boards) is for extreme overclocking (aka LN2) and can be safely ignored.

The RMx is a great PSU, it's actually one that we like to recommend a lot. If the cost difference isn't much, go with the RMx if you can.
