Hey there , Is there any way to games at high settings but load is under 300w? If yes suggest some setup

a 3600 (tdp 65W) + a 1660 super (tdp 125W) should do it.

there are dozens of them... and you didnt specify resolution and target frame rate either

You also have to define what you mean by 300w ?

 

Processors, video cards, and fans in computers are powered from 12v. Some motherboard stuff (chipset, onboard audio, network), SSDs are powered from the 5v produced by the power supply. Sometimes the RAM sticks are powered from 12v, most often are powered from 5v or 3.3v

 

There are high end 300w power supplies which produce almost all these 300 watts as 12v, and internally use very efficient dc-dc converters to convert 12v to 3.3v and 5v as needed. With such power supplies, you can safely pick a processor and a video card that use up to 200-250 watts from 12v and the computer would be stable.

 

However - and this is especially important considering you're from India -  there are lots of cheaper budget power supplies that have a percentage of the maximum watts value reserved for 12v, and a percentage reserved for the other voltages, so for example your cheap power supply could have only 180 watts reserved for 12v and the other 120 watts reserved for 5v and 3.3v, while a modern system barely consumes more than 30-50 watts from 3.3v and 5v.

In India, if you go with cheap power supplies, you are also dealing with LIES, as in the power supply label will actually LIE about its capabilities, so your 300 watts cheap power supply that claims it can do 200 watts on 12v (again, this is what powers your processor and your video card) but in reality the components used to produce 12v can not continuously produce 200 watts, in reality maybe they can only do 120-150 watts.

 

Modern games need a processor with at least 4 cores, ideally a six core. So you can go for example with a Ryzen 3600 that will average around 80-120 watts of power. You can undervolt it and overclock it a little to get less power consumption on average... there will be a tiny performance loss, but not as much as if you'd use a quad core processor instead.

You can do the same with a video card ... for example you can get a RX 570 video card that's very cheap but consumes up to around 170 watts, and you could modify the bios or use Wattman (inside AMD's control center application) to reduce the frequencies and maximum power consumption by some amount, let's say below 150 watts. You would lose performance, but the performance could still be between RX 460 and RX 470... excellent performance for the money.

nVidia cards are more efficient, but they're more expensive, and sometimes something is good enough.

 

For example RX 570 4GB uses around 170 watts while 1650 super uses only around 80 watts and I think you get a bit more performance with the RX 570 ... but a RX 570 is much cheaper and is still perfectly fine for 1080p gaming, you'll get 50-60 fps even on new AAA games, even more if you adjust some quality settings from high to medium-high.

 

So let's say the maximum power consumption for the cpu is 100 watts, then you can safely pick a video card that will not consume more than around 150w or whatever else is left in the power supply's 12v budget (after you substract cpu, fans, mechanical drives)

 

You can look at various video card reviews and you'll see the power consumption ... some example (idle, windows  / gaming) :

 

 

nVidia 

RTX 2070 Super = 12W/215W (peak 230W)
RTX 2060 Super = 10W/180W (peak 200W)

GTX 1660Ti = 9W/125W (peak 135W)
GTX 1660 = 8W/125W (peak 135W)
GTX 1660 Super = 8W/110W
GTX 1650 = 8W/80W
GTX 1650 Super = 8W/95W

RTX 2080Ti = 17W/260W (FE)
RTX 2080 = 15W/225W (FE)
RTX 2070 = 15W/185W (FE)
RTX 2060 = 10W/160W

GTX1080Ti = 13W/245W
GTX1080 = 6W/184W
GTX1070Ti = 6W/175W
GTX1070 = 6W/151W
GTX1060 = 6W/122W
GTX1050Ti = 6W/75W
GTX1050 = 6W/75W


GTX980Ti = 11W/238W
GTX980 - 8W/184W
GTX970 - 9W/179W
GTX960 = 7W/118W
GTX950 = 8W/103W

AMD

RX 5700XT = 12W/220W (peak 250W)
RX 5700 = 12W/185W (peak 200W)
RX 5600 XT = 12W/160W
RX 5500XT = 12W/125W

Radeon VII = 18W/297W (peak 320W)

RX 590 = 16W/245W (peak <5ms = 300W)

RX Vega64 = 20W/295W
RX Vega56 = 16W/255W

RX 580 = 16W/225W (peak power poate fi și mai mare, ~250W)
RX 570 = 16W/175W
RX 560 = 9W/79W
RX 550 = 7W/45W

RX 480 = 16W/164W
RX 470 = 16W/144W
RX 460 = 13W/110W


R9 Fury X = 5W/347W (peak power)
R9 Fury = 5W/275W (peak power)
R9 390 = 11W/253W
R9 380 = 8W/196W

 

From a RX 5500 XT 4 GB review, so the performance of various cards is compared to it (the 5500xt is 100%, the other cards are either slower or faster)

worst case scenario, Aassassin's Creed Odyssey, you're looking at R5 3600 + RTX 2060, these two add up to around 250w max, adding in other components a PC has in order to run they would be drawing 300W down the PSU, more from the wall

 

and I hope you're not trying to push all this with a 300w PSU, those bought separately with wattage this low are all terrible, while those that comes from prebuilt systems often dont have enough cables.
