Corsair RM850X + 2080 ti

Im about to upgrade to a RTX 2080 Ti from a GTX 980 Ti.

 

Do i need to power the 2080 Ti card with two separete 6+2 cables or does one 2x(6+2) cable work?

 

im abit lost here and id love to get some guidance

Separate cables are always safer.  Any reason other than cable management you want to go a single 6+2 that comes with a Y splitter?

It is recommended to use two separate 6+2 PCIe cables to power a graphics card requiring them instead of using one and a splitter to divide the power load over more wires and prevent them from getting hot/overload a single cable. Your power supply (RM850x) should have come with more than enough 6+2 PCIe cables.

You won' fry anything.  Worst that will happen is it trips the PSU and the PC shuts down.  Either way, separate PCIE cables are always the preferred way :) Enjoy your stay on the forum!

Currently using my Titan Xp on a single cable, the 2080 ti would be a similar story. Any high quality PSU can handle daisy chain connectors off a single cable for a demanding GPU, and you should only be using a high end PSU on a 2080ti anyway. With the RMX it would be no problem to use a single cable.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

It doesn't hurt to run 2 cables. I'd just run a cable for each 8-pin header, just to be safe.

If it doesn't work, you'll definitely know hahaha.  It won't destroy anything so no real worries there.
