The caller Nvidia GeForce RTX 40 lineup includes immoderate of the astir power-hungry graphics cards connected the market. Because of that, you whitethorn beryllium wondering if you’ll request a caller powerfulness proviso (PSU) successful bid to enactment the borderline monstrous capabilities of the RTX 4090.

To reply immoderate of these concerns, Nvidia released caller information astir the powerfulness depletion of its caller GPUs. The conclusion? Well, it’s truly not each that atrocious aft all.

Prior to the authoritative announcement of the RTX 40-series, the cards person been the taxable of much power-related speculation. The flagship RTX 4090 received the astir sum of all, with galore rumors pointing toward insane requirements on the lines of 800-900W. Fortunately, we present cognize that those rumors weren’t true.

The RTX 4090 has a TGP of 450W, the aforesaid arsenic the RTX 3090 Ti, and calls for a minimum 850W PSU. The RTX 4080 16GB takes things down a fewer notches with a 320W TGP and a 750W powerfulness supply. Lastly, the RTX 4070 successful disguise, besides known arsenic the RTX 4080 12GB, draws 285W and calls for a 700W PSU.

Nvidia claims that this is not an summation from the erstwhile generation, but it benignant of is — aft all, the RTX 3090 had a TGP of 350W. With that said, it’s not arsenic atrocious arsenic we had thought, but galore are inactive near to wonderment if they request to upgrade their existing PSUs oregon not.

Nvidia has present assured its customers that they tin instrumentality to the PSU they presently ain arsenic agelong arsenic it meets the wattage requirements for that fixed card.

Similarly, Nvidia doesn’t expect determination to beryllium immoderate problems erstwhile it comes to 8-pin to PCIe Gen 5 16-pin adapter compatibility. As said by Nvidia connected its FAQ page: “The adapter has progressive circuits wrong that construe the 8-pin plug presumption to the close sideband signals according to the PCIe Gen 5 (ATX 3.0) spec.”

There’s besides different amusive small information to beryllium recovered successful that FAQ: Nvidia confirms that the alleged astute powerfulness adapter volition observe the fig of 8-pin connectors that are plugged in. When 4 specified connectors are utilized versus conscionable three, it volition enable the RTX 4090 to gully much power (up to 600 watts) for other overclocking capabilities.

There person besides been questions astir the durability of the PCIe 5.0 connectors, which are rated astatine 30 cycles. Some mightiness see that to not beryllium much, but Nvidia clears this up by saying that this has astir ever been the case, oregon astatine slightest has been implicit the past 20 years.

Lastly, Nvidia clarified the substance of the anticipation of an overcurrent oregon overpower hazard erstwhile utilizing the 16-pin powerfulness connector with non-ATX 3.0 powerfulness proviso units. It had, indeed, spotted an contented during the aboriginal stages of development, but it has since been cleared up. Again, seemingly thing to interest astir there.

All successful all, the powerfulness depletion fears person mostly been squelched. Nvidia did ramp up the powerfulness requirements, but not arsenic importantly arsenic expected, truthful arsenic agelong arsenic your PSU matches what the paper asks for, you should beryllium fine. Let’s not respire that suspiration of alleviation yet, though — the RTX 4090 Ti mightiness inactive happen, and that volition apt beryllium 1 power-hungry beast.
