ASUS ROG Astral RTX 5080 OC BIOS Update Increases Max. TGP to 450 W - Originally 400 W

T0@st · Friday at 7:43 PM

TechPowerUp's W1zzard did not honor the ASUS ROG Astral RTX 5080 OC Edition graphics card model with any awards—as disclosed in his late January evaluation, a major negative point was highlighted: "no additional power limit increases allowed." The premium-tier ASUS offering managed to top TPU's "Maximum Overclock Comparison" GeForce RTX 5080-class table; comfortably leading the pack with an out-of-the-box (default) 400 W power setting. Reviewers and well-heeled owners—of this $1500+ special quad-fan package—have lamented the apparent lack of extra headroom. Sitting in fifth place was GIGABYTE's RTX 5080 GAMING OC SKU; a card that can support up to 450 W. As reported by VideoCardz earlier today, ASUS has taken onboard aforementioned feedback.

Resultant under-the-hood tinkerings were implemented mid-way through last month. The "ROG Astral GeForce RTX 5080 16 GB GDDR7 OC Edition" support page has welcomed a new downloadable file—authored on March 14—this BIOS update is advertised as being capable of: "increasing the (model's) maximum TGP to 450 W." Additional bragging rights will be granted with this patch; owners can boast about their expensive bits of kit being further enhanced—NVIDIA's reference specification TGP/TDP is 360 W. Thumbs up go to Team ASUS once again—mid-February Astral series updates tweaked noise profiles; not too long after an absorption of launch day criticism.

Why not increase it to 800TDP? 1000TDP? I mean it's just a limit. If the VRM and temps check out...boost the heck out of that thing. NVIDIA is boasting the highest TDP this gen...hello fermi

No matter the dialed wattage it's still a disturbingly overpriced product that doesn't bring any meaningful improvement over the similarly priced 4090* that's not even from the current generation.

*MSRP-wise

Who cares about the TGP increase? Tell us how much this BIOS update increases the MSRP :nutkick:

Coverage for this type of product is unmerited. Stupider price than usual. Attention should be on products that people might actually buy.

Well shucks, I think I just might download this. Thanks for the news!

Indeed, 100%

So now it can perform like a stock rtx 4090 as it the same tgp

Better seel 4090 get this card then....

I don't care much about the overpriced Astral, but if we can flash it to another 5080 board, it would be nice.

Because only a 450W adapter is included.

Depends on extra power delivery components on the said model, otherwise some components would work harder than they should to the point of early failure.

I hope they do this for their OC TUF models too.

Nvidia:What's the status on connectors melting on 5xxx series
Devs and Engineers:Well the news died down a bit seems to be going ok
Nvidia:Well we cant have that now can we...Increase TGP at once!

Media coverage may have died down but we are still seeing melting connectors with fair frequency in various user spaces.

It appears as though Nvidia has no interest in addressing the issue at all. If it's not going to be fixed, it's a negative against purchasing Nvidia cards that everyone needs to consider.

Soooo...to summarize (without all the techno-babble):

Before, it only required a small nuke reactor to run it, and it would melt slowly....

Now, it just needs a bigger one, and it melts faster than ever, hahahahahahaha

For the life of me I don't know why anyone would spend +50% MSRP for a better cooler, but surprisingly the Astral is selling rather well.

Its selling very well because they seem to be the main ones sold at Microcenter/Newegg. If lower models were available, I think most of us would have bought the cheaper versions. Microcenter seems to have received a lot of the Astral 5090 LCs too! My guess is Asus received the most GPUs followed by Zotac - of course that is just what I've seen.

On Topic:

I don't know about this 450W BIOS... I installed it and it dropped the TDP to 360W. If anyone had success with this please let me know.

They wont fix it on 5xxx they have no intention of fixing it,ordinary customer is not important,so here is hoping for 6xxx to return to 3xxx power delivery or something similar and improved, but knowing nvidia they are just going to make things worse one way or another,data centers are their main customers we are just here to pick up the crumbs.
