Hiya,

I'm generally very happy with my RTX 4090 Suprim X but this card is known for its relatively high idle power consumption. Now, I'm not getting anything crazy like people who have reported 80W when watching YT videos but AFAIK the ~30W (board power draw) I'm seeing is still higher than other manufacturer's cards which drop all the way to 10W when idle.

Thus my question: Would it be advisable to update the vBIOS? Do the latest vBIOS versions have fixes for the idle power consumption? Does the board power draw drop significantly below 30W when simply using Windows for you guys who have an updated BIOS?

I'm a little hesitant to update the vBIOS because of the reports of lower power limits in newer BIOSes and resulting performance degradation. I also would not update the vBIOS if there is no fix for the idle power consumption anyway.

In short, with regard to the latest vBIOS version: Is there a fix for idle power draw and if so is there also a way to keep the 520W power limit?

Several factors affect Idle Power, the total number of monitors Display settings and Refresh rate

Thanks :) .

Then let me ask the following: Do you or does anyone here think that 30W board power draw is too high a power consumption for a MSI RTX 4090 Suprim X connected via DP 1.4 to a single 42.5" ASUS PG43UQ display, running a resolution of 3840 x 2160 at 144Hz? Or is 30W perfectly normal and not likely to improve with an updated vBIOS?

The monitoring software I'm using is GPU-Z version 2.50.0. My vBIOS is version 95.02.18.40.45 (never updated so far).

Check in what P-State is the GPU when you have this power consumption also check the GPU clocks.
Also try latest 526.98 WHQL [it's address known issue with idle power consumption]

Based on this sounds about right:

MSI GeForce RTX 4090 Suprim X Review

The MSI GeForce RTX 4090 Suprim X is the quiestest RTX 4090 custom-design that we've tested. It runs at an unbelievable 28.6 dBA in our review, under full load, 4K, 60 FPS with ray tracing enabled, and temperatures are still really good.

I think that is too high for any modern GPU
My RX6900XT and RX 6800 use less than 5 Watts on idle so ya 30 watts on Modern Hardware is bad. Nvidia has work to do
Set to disply Minumin levels

Hi,
no news here?

I had an ASUS Strix OC RTX 4090:
After BIOS-Update was the IDLE power consumption at 11W (LED ON on the highest level).

Now with the MSI Suprim X RTX 4090: 28W.
LED completely turned off: 26W.

Please MSI, can you fix this?

Edit: If I start Netflix and close it, IDLE power consumption remains at 38W.

I don't think this problem will fixed if there's not enough complaint about it. So I doubt in the future there will be any BIOS update from MSI that will fix this, sadly.

The only choice if you care about low power consumption at idle is to sell you card and buy from another brand. :(

Btw, to answer your original question. No, update the vBIOS, whether it is the Silent BIOS or the Gaming BIOS will not reduce idle power consumption, not with the latest ones.

If you're concerned about not being able to flash the original vBIOS back, you can use GPU-Z to simply save it, or, even better, upload it to TechPowerUp's database (if it is not available yet). That way, after flashing the newest version, if you're not happy with it, you can always flash back to the original version that came with your card.

It is still worthwhile to update to the newest versions: 1st: it fixes some black screen issues with certain setup. 2nd: it fixes graphics issues with Need For Speed: Unbound, and probably future games as well, if they have the same issue as Need For Speed: Unbound.

What BIOS update are you referring to on the Strix card? The latest one on their support site?

What was the idle power consumption before that VBIOS update? :) Was that with a single monitor or multiple?

Did you ever solve it for your MSI Suprim X card? I don't see any VBIOS updates for the Suprim card on the support site.
