troubleshooting Is it ok to daisy chain 2 of my 3x8pin PCIE for a 3070 ti Asus Strix OC ? and 4+8EPS question

[Oxamis]

Hello There !

 

I am trying to connect my Corsair HX750 PSU to an Asus 3070ti Strix OC GPU. This GPU requires 3x8pin PCIE.

My problem is that the PSU only came with 2 splitted PCIE power cables. I plan on using one cable in a 1 to 1and the other cable in a 1 to 2 daisy chain.

 

I understood from what I read that this solution will lower the performances of the GPU. Can it also be dangerous for the GPU or the GPU lifespan ?

Can I wire the GPU like this only for a temporary solution ?

 

I have 4 PCIE/CPU outputs on the Corsair HX750 PSU, I could buy another PCIE cable to plug into my GPU but my mother board has a 4+8EPS/12V.

Do you think the mobo needs the 4+8 EPS or can I only plug 8EPS in the mobo and use a PCIE slot on the PSU for an additional PCIE for my GPU ?

 

The specs :

CPU : AMD Ryzen 7 5800X

Motherboard : ASUS Strix  B550 F Wifi II

RAM : 2x16GB Kingston Fury Renegade

GPU : 1x Asus Strix 3070ti OC edition

Case : Phanteks P500A DRGB

Storage : M2 NVME Samsung 980 Pro 1TB

PSU : Corsair HX750

Cooling : Arctic Liquid Freezer II 360 ARGB

Fans : 4x140 mm Phanteks

On a crappy power supply, daisy chained cables on a demanding graphics card can result in damage, such as melting a cable. But for the HX750, one daisy chained cable won't be a bad thing.

the additional 4 pin EPS connector is for extreme overclocking. For normal users (that is, not using liquid nitrogen), you won't need the additional 4 pin at all.

You most likely will be fine

This.  

 

A lot of PSUs use 18g or smaller wire and cheap terminals.  These same companies are the ones that spread the FUD about having to use individual cables.  The Corsair cables are 16g with HCS terminals, so you're good.

 

It's really a shame that Nvidia didn't move to the EPS12V connectors on the Ampere cards like they did with the workstation cards.  If they REALLY wanted to make sure people didn't use pigtails, they should have gone that route.
