I'm assuming you're talking about the Seasonic Focus GX.

They are exactly the same price in the end. 90+20 = 110 however the Focus GX is a Low priority A tier while the Corsair RMx is a Best in class A tier according to the PSU tier list.

RMx(2021) is highlighted in gold so you're actually better off buying this corsair RMx and then buying the cable since the price will be the same in the end.
Note this older (and very excellent) version does not include the 12VHPR or 12V-2X6 cable that would allow bypassing the clunky triple-head GPU power adapter for NVIDIA 4xxx GPUs. The modular cable costs $20 separately.

Amazing price! I paid $135 when I built this 12700K rig this past year.

yeah, it's just the fact he already had the 750w ordered that included the 12HPWR cable for $90.

Yes just don't forget to add 12VHPWR ATX3.0 Corsair Cable for $20 ($30 if you need white)
Would I need this if I just want to use this as a bench power supply?

It adds a promo code into your cart. It states it underneath the model. Additional $35 off with the promo code.

"+ $35 off w/ promo code APRCS35, limited offer"

I grabbed one for one of my file servers that keeps resetting without error messages so I'm wondering if it's just an old power supply giving out. at this price, and without the need for ATX 3.0, no reason not to get this model

Not seeing that on Amazon, the promo code is for Newegg. They said the price was the same on Amazon. Looks like they deleted their comment.

You can get aftermarket cables for cheaper. Just search amazon.
But came here to say the 1000w one is only $20 more. These are the Tier A psus
Thank you. I didn't realize the 1000 was on sale also. I bought the seasonic 850 because it included the GPU cable, but would rather a 1000 watt PSU for a 4080 build I'm doing. The Corsair will be just that, and after adding the Samsung 990 pro 2tb drive, I came out with $105 of total discounts. ($10 + $30 for combo and $50 + $15 for product discounts). The total was $244.98 + tax. I may still buy the Corsair cable, but that's worth it to get the higher wattage PSU.

RMx is a much better PSU. The "e" stands for economy.
