I was planning on getting an RTX 3070 this morning, but I was a little worried because it say the recommended PSU wattage is 650 watt. Do you think I could get away with a 550 watt for a little bit before I pick up a new one that is higher wattage, or do I absolutely need a 650 watt PSU? Thanks for any help y'all can provide.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

It also depends on the rest of your system. The required wattage will change if you use a Ryzen 5 3600 or a Threadripper 3990x. Also overclocking is a factor to consider, together with all your fans and other components.

A generally balanced system using a 3070 should get away with a good quality 550/600W psu. If you consider overclocking or using higher end components, 650-700W would be advised.

Nvidia recommends 650W for a 3070, but don't list that this has to be a gold/platinum power supply.

That's definitely ok for your PSU.3600@4.35Ghz@1.225v only draws 100w from socket.BTW,I use the GX550 from coolermaster pair with a 2080s OC and trun out to be in good condition.(with same cpu settings as mentioned)

idk, linus said that ampere card can have power draw spikes so if your psu is just enough for the card, the power spikes may cause shutdowns

rather be a 'plug, install the drivers and play' scenario (when the new psu is already installed) then 'plug, install the drivers, play, psu not enough and system crashes, going to the store to buy a new psu, unpluggings the cables, getting the psu out, putting the new one in, plugging the cables and the gpu and playing' scenario.

you cant get away with a weak psu with this gpu series

Same question, would a 3900x and a 3070 be fine with a 650w psu?
