Hi all,
 
I've been encountering a strange issue lately that mostly occurs when opening power limit, or simply putting my system under a heavy sustained load like 4K Ultra MSFS 2020. It seems as though my 1000W Phanteks Revolt X is experiencing a trip of over-current protection, this is with the October vbios release (I don't know if there has since been an update?) The computer completely powers down and does not self-reboot - however the motherboard lights always seem to stay on and I can usually just press the power button to restart, and if not I flip switch @ psu and I'm good to reboot. I have heard of RTX 3000 cards encountering these issues with power supplies when there is a certain spike in draw, but 1000W Platinum should certainly be enough no? I have considered that this power supply is built to support two systems, but have to imagine that it's default operating mode is to provide power to whatever is primarily pulling from it. If anyone has feedback I would greatly appreciate it, the card appears to operate wonderfully so I really suspect the issue is the power supply. I have a 1200W incoming to test this theory.
 
Thanks,

No, you will need to replace the power supply.
 
This has nothing to do with the PSU's total capacity--you are not exceeding 1000W--it has to do with the PSU's overcurrent protection system, which is 'tripping' due to a sudden high "spike" in amps load.  This spike makes the PSU think that a surge has occurred and it shuts off to protect the system.  I do not know if this is a Seasonic rebrand, but some Seasonic platforms from the past that used the OCP regulation in the old "X-series" platform, was also used in the early Prime and Focus models, and on OEM's that use Seasonic as their base supplier.  This was not limited to only Seasonic base units (Note: Corsair does NOT make their own PSU's--they add their own hardware to it, but they use Greatwall, FSP, Superflower, Seasonic, etc), but I am not sure if anyone has an exhaustive list of PSU manufacturers and OEM's with units that will trip OCP with Ampere video cards.
 
Seasonic themselves are allowing RMA's of PSU's under warranty and exchanging them for updated models with more lenient OCP circuitry (I am not sure if they will allow RMA's on units not under warranty, but I saw someone with a Focus Plus Gold (tripping OCP, this is the old model) get an RMA exchange from Seasonic with a Focus GX-850 (no trip, working perfectly, updated OneSeasonic odel), for example.
 
You would have to contact Phanteks about this and see if they will allow a similar RMA or cross-shipment option so you aren't without a power supply, but don't hold your breath, especially if your unit is out of warranty!

As I mentioned, I do highly suspect the issue is the PSU - good to know that OCP trips are common, was starting to panic a bit! I don't know if Corsair 1200W option or EVGA 1200 P2 is better... inclined to try to go EVGA, of course. :)

Is there actually an update to this in the works? I've seen a few comments saying that, but I can't find any sources. I've read too many issues with this BIOS. I want to try overclocking with a 500W limit since I am hitting a wall in my overclocking But not until there's an update.

Have the same resultat with à Corsair AX1200i.
What i do notise is that the rgb on MB flickors on-off and requier multipel attempts to start it again.
I blame what is a common issue on the AX1200i well known for man years on the unit and nothing has been done to fix it from either corsair or flextronic to fix it and courtage on med units asswell for some.
I will never take the same risk again with Corsair so i send it to recycle facility and let a BeQuiet DarkPowerPro12 1200w deliver the power in the future.

Reading through this thread has been eye opening and has made me rethink whether the FTW3 ULTRA 3090 is the best starting point for overclocking a water-cooled system. If you were starting a clean build, would you still go with the FTW3U or choose something else? And, if something else, then what?

I keep seeing people mentioning firmware updates with precision - I did not get one with my 3090 FTW3 Hybrid. Can anyone else with the same card confirm whether they got a firmware update on first use of the card with precision or not?

At this point waiting for a Hydrocopper card would be worth considering. You'll get in queue nice and early if you keep an eye out, and hopefully by the time those hit the market, they'll have a bios update out again etc. & the issues will mostly be fixed.

I did.  Same card (3090 FTW3 Ultra converted to Hybrid kit).  First time I launched PX1, I got a firmware update.  That was before I flashed the 2 from Jacob, then the XOC on top.  I'm not sure what the first one was, honestly.  I was so excited to have it installed and set up that I just moved on to flashing the others... Not an ultimately helpful comment here, but I have the same card and got that update.
Edit: I might be crossing threads here, sorry!

Thanks. I was wondering what the story was with those.

I was in the same position as you and given the total silence from EVGA, there was no way I was going to jeopardise my build based on hope alone. If I could have, I would have bought the Strix OC but they are seemingly non existent so I went with the MSI Suprim X and have an Alphacool block coming. I would have loved to go the Strix plus the Aqua Computer block with active backplate and the Vision OLED screen (Which is now looking likely to be available for the FTW3 as well).

I would have totally changed direction and stayed with the FTW3 if there was some communication and a guarantee that the power issue would be fixed. Alas, there has not.

I was also looking at the Asus Strix OC. But the truth is I will probably end up buying whichever one becomes available since I really have no visibility of what’s in the pipeline.
