Is a Corsair RM850e 850w PSU good for a XFX 7900 gre?

Im planning on building a pc with a 7900 gre (this one: https://pcpartpicker.com/product/wXtLrH/xfx-rx-79gmercb9-radeon-rx-7900-gre-16-gb-video-card-rx-79gmercb9), my question is that in the specs of the GPU says it needs external Power: 2 PCIe 8-pin, but the PSU I am planning to use which is a Corsair RM850e (2023) 850 W 80+ Gold (this one: https://pcpartpicker.com/product/4ZRwrH/corsair-rm850e-2023-850-w-80-gold-certified-fully-modular-atx-power-supply-cp-9020263-na) says it has 0 PCIe 8-Pin Connectors but has 3 PCIe 6+2-Pin Connectors, can I use those or do I need to find a new power supply that has 2 PCIe 8-Pin Connectors?

I'd recommend an RM850x over it for $99. e series has a whine noise for many people.

Yes it's a a good psu and pcie 8 pin and pcie 6+2 pretty much mean the same thing so you'll be fine.

And are you just upgrading your psu and gpu or building a new system?

If your building a system you can get the psu for $95 from Newegg with bundle deals and also get some deals on other parts like cases and nvmes

If not you can also go with a MSI - MAG A850GL for $90 after mail in rebate

6+2 is effectively the same thing as 8, you're fine.
