ASUS ROG LOKI SFX-L 1000W Platinum Power Supply Question
The pin out has to be specific to the PSU, you can get custom cables from CableMod or others as long as they have specific PIN out information for the PSU. Otherwise you can use extensions but assuming you are using a SFX-L PSU you are most likely building a SFF/MFF system so more compact cables will be ideal. In this respect native custom cables would be preferred. https://store.cablemod.com/products/?filter_series=rt-series More on reddit.com

Rma this unit and get corsair sf1000(sfx one, not sfx-l). Super quiet in my build, have it for 1.5 years. Started with 7700+4080s, now sidegraded to 9070xt. Fan never spins at idle, doesn't start spinning immediately with load either, also fan is fdb, not dbb like loki, so super quiet More on reddit.com

Asus ROG Loki 1000W SFX-L PSU now shipping as ATX 3.1 with 12v2x6 connector
I have the "old" version which supports atx 3.0, but I just ordered a new one from amazon that says "compatible with atx 3.1" 🤔 On the picture it says atx 3.0, just like one I already have 🤷‍♂️ I'm in for a supprise I guess 😅 https://amzn.eu/d/8fc2iBD More on reddit.com

Hi everyone! I'm upgrading to a 5080, right now im running a 3080 with XPG Core Reactor 850w, having a 7800x3d doesnt demand too much power, but I want to buy a 1200W so if I upgrade in the future I can still use that PS, the main thing that I don't know is... there is too much difference in those models? Can both work on my 5080? (I heard 5090 had some Cable issues/burning).

THanks a lot! :)

May 29, 2025 -

Hi Folks, I've built a SFF PC using a ROG LOKI SFX-L 1000W Platinum PSU. My config is as follows:

https://uk.pcpartpicker.com/list/7Z2JZc

So the new build PC doesn't fire up after I wired it all up. Tested everything but still dead. I checked the PSU using the paperclip test but the fan or lights on the LOKI PSU don't come on.

I completely d/c and removed the LOKI on the new build PC. I removed a 1000W ATX PSU (not modular) from from a very old working PC and only connected the ATX connector to the MB on the new build. The fan on the old PSU and lights on the MB turn on.

I connected the LOKI only to the ATX connector on the old working PC MB but fan or the lights on the LOKI or the lights on that old PC MB don't go on either.

Thinking the PSU was faulty I have raised an RMA with the retailer. At the same time,, I reordered the same PSU from Amazon late last night and it has come today but getting the same problem. Is there anything I should be (or not be) doing? Am I missing something? Tearing my hair out here. 😭 I've done builds before but not had this problem.

Would really appreciate any help please ...!

Many thanks,

iq
