The latest Nvidia RTX 5000 power consumption rumors have me worried that my PSU won’t be nearly enough for the RTX 5080
- Nvidia RTX 5090 and 5080 are rumored to have higher power consumption
- The RTX 5090 may require 575W, slightly less than some previous rumors
- RTX 5080 could reach 360W, which is unfortunately slightly higher than previous speculations
Nvidia’s RTX 5090 and 5080 are expected to be unveiled at CES 2025 – likely alongside RTX 5070 models as well – and we’ve just heard more about the potential power consumption of these next-generation GPUs.
VideoCardz noted that two mainstream hardware leakers on X, Hongxing2020 and Kopite7kimi, have agreed to alleged power figures for these Blackwell GeForce graphics cards.
Assuming that their beliefs are on the money, the former leaker brought up the claim that the RTX 5090 will demand 575W in terms of power consumption, and then Kopite7kimi replied with the claim that the recently spotted RTX 5080 will consume 360 W of power.
No clarification is given as to how big these GPUs might be, or whether the RTX 5090 will be limited to a dual-slot graphics card, which is the follow-up question several X residents asked in the thread above.
Analysis: Sizing next-generation options
The reason people are asking about the size of the next-gen graphics card (aside from that, it’s an obvious point of curiosity anyway) is that previous rumors have suggested we might see a wonderfully slim RTX 5090, limited to two slots in size by Nvidia. (While the RTX 4090 takes up at least three slots in a PC – or four in many cases).
Essentially, with the 575W figure mentioned, people are coming to the conclusion that this won’t be a two-slot board as per the previous rumor. (Unless Nvidia has really worked some magic with a slim cooling solution to keep a power-hungry graphics card in check). That is why this question is asked.
In fact, 575W is a slight drop from an earlier rumor mill prediction that we’ll see the RTX 5090 use 600W, and in that respect it’s somewhat positive news. Well, a little – Kopite7kimi also hinted that the flagship’s power consumption would drop slightly in recent times – but it’s clear that this will still be a demanding GPU. From what we’ve heard elsewhere, it’s probably more aimed at professional use than PC gaming, and could be extremely pricey – although as a GeForce model it’s still officially a consumer (gaming) card in theory.
Of course, if all this works out, the RTX 5080 will also look big on the power side of the equation here. Kopite7kimi has indeed indicated that it could be around 350W in the past, so their prediction has been revised up slightly here to 360W.
That could be bad news for anyone using a PC power calculator to find out if their power supply can handle a new RTX 5080, as closer to the 400W mark could mean that even a relatively powerful PSU is closer to the limit or will work or not.
It would certainly put the RTX 5080 out of reach of my 650W power supply, but I’m still hoping the RTX 5070 will be significantly slimmer and a good fit for an upgrade to my gaming PC – or the RTX 5070 Ti, with a bit of luck. To be honest, I don’t expect the RTX 5080 to be in my price range anyway, especially given the rumors surrounding the cost of these next-gen graphics cards – other options will be on the table from AMD at RDNA 4 launches, so you’ll have to take that into account as well keep with it.
Whether all these predictions turn out to be correct or not, we’ll have to wait for Nvidia’s big reveal on January 6 – but either way, everything from the rumor mill suggests we’ll see increased power consumption for Blackwell’s graphics cards. .
In addition to the next generation of desktop graphics cards at CES 2025, we may also be treated to the launch of mobile versions, and perhaps DLSS 4 as well.
