This is the #1 reason why I haven’t upgraded my 2080 Ti. Using my laser printer while my computer is on (even if it’s idle) already makes my UPS freak out.
But NVIDIA is claiming that the 5070 is equivalent to the 4090, so maybe they’re expecting you to wait a generation and get the lower card if you care about TDP? Although I suspect that equivalence only applies to gaming; probably for ML you’d still need the higher-tier card.
- iwontberude 2y agoThat’s because you have a Brother laser printer which charges its capacitors in the least graceful way possible.
- throwaway81348 2y agoPlease expand, I am intrigued!
- lukevp 2y agoThis happens with my Samsung laser printer too, is it not all laser printers?
- bob1029 2y agoIt's mostly the fuser that is sucking down all the power. In some models, it will flip on and off very quickly to provide a fast warm up (low thermal mass). You can often observe the impact of this in the lights flickering.

- dogline 2y agoIf my Brother laser printer starts while I have the ceiling fan going on the same circuit, the breaker will trip. That's the only thing in my house that will do it. It must be a huge momentary current draw.
- Reason077 2y agoDoes a laser printer need to be connected to a UPS?
- iwontberude 2y agoIt's not connected to the UPS directly, it's causing voltage dip on the circuit tripping the UPS.
- grujicd 2y agoFaulty iron in another room fried my LaserJet. UPS isn't just for loss of power, it should also protect from power spikes. Btw. printer was connected to a (cheap) surge protector strip which didn't help. On positive side nothing else was fried and laser was fixed for 40 euros.
- adolph 2y agoIs it ironic that the electrically expensive part of the LaserJet, the fused, is pretty much an iron in a different format? https://www.inkguides.com/printer-fuser/ https://www.inkguides.com/printer-fuser/

- bob1029 2y agoI would be careful connecting laser printers to consumer UPS products. On paper all the numbers may line up, but I don't know why you'd want to if you could otherwise avoid it. If the printer causes your UPS to trip when merely sharing the circuit, imagine the impact to the semiconductors and other active elements when connected as a protected load.
- jandrese 2y agoThe big grain of salt with that "the 5070 performs like a 4090" is that it is talking about having the card fake in 3 extra frames for each one it properly generates. In terms of actual performance boost a 5070 is about 10% faster than a 4070.

- p1esk 2y agoSource for your 10% number?
- brokenmachine 2y agoI heard them say that in the Hardware Unboxed youtube video yesterday. I think it's this one https://youtu.be/olfgrLqtXEo https://youtu.be/olfgrLqtXEo
- p1esk 2y agoI don’t see any testing performed in that video. Did I miss it?
- brokenmachine 2y agoNo testing, they estimated from the available information.
- rafaelmn 2y agoI think people are speculating based on graphs Nvidia has on their product page.
- buran77 2y agoAccording to Nvidia [0], DLSS4 with Multi Frame Generation means "15 out of 16 pixels are generated by AI". Even that "original" first out of four frames is rendered in 1080p and AI upscaled. So it's not just 3 extra frames, it's also 75% of the original one.

- UltraSane 2y agoWhy would you have your laser printer connected to your UPS?
- pshirshov 2y agoYour UPS is improperly sized. A 5kW Victron Multiplus II with one Pylontech US5000 would cost you around €1600 and should be able to carry all your house, not just your printer.
- IIsi50MHz 2y agoThanks for those recommendations. From a few minutes of searching, looks like they would cost 1.5x to 2x that in USA. We decided to start very small, because we couldn't figure out from the websites of various backup energy installers who was least likely to grossly inflate specs and prices. So, we recently bought a low-end expandable Anker Solix C1000 for around $500 USD as manual reserve power, mainly for the fridge. It seems to be intended more for "glamping", but Anker has good reputation for various unrelated products.
