uNoTopia Posted February 25, 2021 Share Posted February 25, 2021 (edited) Hi, I have a problem understanding the following: I have a RM650x. Spec sheet says it has 4x PCIE: https://www.corsair.com/eu/en/Categories/Products/Power-Supply-Units/Power-Supply-Units-Advanced/RMx-Series/p/CP-9020178-NA#tab-tech-specs If i actually look at the PSU, I can only see 3x PCIEx8: How would I go about connecting 2x GPU's? Can I just use two 8-pin to 2x 8-pin Y cables?? Update: The RM650x came with 1 of those Y-cables so how can I get a 2nd one? I am confused. Here you can see an unboxing where actually 2 cables sh ould be in the box: [ame] [/ame] PS: for power draw: they will run at 50% power limit, that means I should be able to run these on this 650W, am I right? With 1x 3070 the system is pulling ~240W. Edited February 26, 2021 by uNoTopia Link to comment Share on other sites More sharing options...
bloody74 Posted February 26, 2021 Share Posted February 26, 2021 (edited) ein kabelstrang pcie hat 2x 6+2pin ("Ykabel") für die grafikkarte und 1x8pin für pcie am netzteil. 2 von diesen kabelsträngen sind dabei, somit 4x 6+2pcie für die grafikkarte und 2x8pin pcie am netzteil^^ Edited February 26, 2021 by bloody74 Link to comment Share on other sites More sharing options...

Are you saying this PSU comes with 2x Y-cables? I only had 1 in the box though... is that normal? Link to comment Share on other sites More sharing options...
Corsair Employees Corsair Notepad Posted February 26, 2021 Corsair Employees Share Posted February 26, 2021 A RM650x is not going to be adequate enough for two 3070's Link to comment Share on other sites More sharing options...
uNoTopia Posted February 26, 2021 Author Share Posted February 26, 2021 A RM650x is not going to be adequate enough for two 3070's I will run both @ only 50% TDP so it should be suffice. I am still wondering if the RM650X should have come with 2x Y cables in the box, seeing as it is advertised as 4x PCIE? Link to comment Share on other sites More sharing options...

Corsair Employees jonnyguru Posted March 5, 2021 Corsair Employees Share Posted March 5, 2021 You're going to be mining with this, aren't you? Link to comment Share on other sites More sharing options...
uNoTopia Posted March 5, 2021 Author Share Posted March 5, 2021 You're going to be mining with this, aren't you? Correct. 650 really is enough, full system with 1x underclocked 3070 draws half of what this thing can deliver so no need for another PSU. I have a response from Corsair support, thanks all for your input. Link to comment Share on other sites More sharing options...
