RodrigoDRT Posted September 17, 2020 Share Posted September 17, 2020 (edited) planning to buy this card, but it needs 3x 8 pin from psu, does this HX750i has what it takes? https://www.msi.com/Graphics-card/GeForce-RTX-3080-GAMING-X-TRIO-10G/Overview Edited September 17, 2020 by RodrigoDRT Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted September 18, 2020 Corsair Employees Share Posted September 18, 2020 Considering the HX750i has four PCIe connectors.... yes. Link to comment Share on other sites More sharing options...

I suggest getting a 1000W unit which has more 12V cable headers as more and more motherboards are demanding dual power cables themselves. Link to comment Share on other sites More sharing options...
Kallex Posted September 27, 2020 Share Posted September 27, 2020 Can you elaborate is that HX750i specifically lower rated PSU..? I checked the cabling slots from the picture, it seems to have 2 + 3 slots for 8 pin CPU/PCIe. That would suffice for 2x to CPU and still leave 3x PCIe open for use. Also the RTX 3080 cards should do just fine with 2x PCIe cables (that split to total 4x connections). At least where I live, I bumped into a shortage of 850W+ PSUs when upgrading, so its not necessarily easy (or financially viable) to just upgrade for "just to be sure". Don't get me wrong, I love my new HX1000i, but in my use case I plan to run a bit more than just one RTX 3080 on it. Link to comment Share on other sites More sharing options...

An HX750i can easily power a GTX 3080 card. Link to comment Share on other sites More sharing options...
Hepokatti Posted September 30, 2020 Share Posted September 30, 2020 I have HX750i with I9-9900k and MSI RTX 3090 Trio. Have been working without single crash from last Thursday. Unfortunately I had to change case, 680x was too small for 3090 Trio with h150i AIO on front... Link to comment Share on other sites More sharing options...
Vegan Posted September 30, 2020 Share Posted September 30, 2020 some older models of power supplies do not have enough 12v plugs give modern motherboards wanting dual EPS12V cables etc uppity video cards often have 3 8-pin cable requirements so units like my RM650 which only has 4 12v plugs is hard pressed My HX1000i has more 12V plugs so i can handle the demanding cards with adequate cables Link to comment Share on other sites More sharing options...
