Change the power source for a Lenovo ThinkStation S20
The available power can deliver up to 475w at 12v, with 125w dedicated to 3.3v and 5v. This setup reflects a typical group regulated ATX power supply. Newer gold-based designs with higher efficiency can reach 650w or more on 12v, then switch to DC-DC converters to provide 3.3v and 5v as needed, eliminating the need for a separate 125w unit. Modern computers usually consume only 40-50w across both voltages, making it practical. Unless you plan to use high-end components like a GTX 3070, your PSU should suffice. What hardware do you expect in your computer or can someone estimate your component usage to avoid overspending on power supplies?
I really dislike this a lot. It doesn't connect to the main topic, does it? It's an RTX 3070, not a GTX 3070, and it's not the first model with RTX technology.
So far it has A DVD-R Burner, 2 HDD and 1 SSD, Nvidia GTX 970 (4GB) with 24 GB Of Ram. I wanted to swap out the 970 for a Geforce RTX 2080 Super. Edit: This is a work computer and it's the only one I have so I don't wanna risk installing this card and destroying it and the PC.
I don't care. They only called it RTX to shove in my face that it has raytracing, which most people don't care about. So you have something like this: 1. CPU - probably around 100w or less from 12v you don't say what cpu you have but few 4-6 core cpus go above 100w 2. motherboard - maybe 20-30w, most from 5v and 3.3v (chipset, onboard audio, onboard network) 3. ram - around 1-2 watts per stick, so 6 sticks .. let's say around 15 watts, usually powered from 5v but could be 12v 4. hard drives .. around 8-10 watts each , half on 5v , half on 12v 5. SSD, usually less than 3 watts, from 5v only 6. DVD burner .... around 5 watts while reading discs, mostly 12v due to motor spinning the discs .. around 8-10w while writing discs 7. fans consume around 1-2 watts each 8. The GTX 970 consumes up to 180 watts from 12v So you're looking at around 350 watts maximum from 12v out of a budget of 475 watts - 200w for video card, 100w cpu, 50w the rest. When gaming, a RTX 2080 Super peaks at around 265 watts for brief periods (less than 2-3s), and sustained it can stay at around 250 watts. So basically, if you get cpu AND video card to 100%, you may get close to 400-420w out of 475w budget. It gets close to the limits of the power supply, but in real world the video card is only gonna reach 250w in games. While rendering, doing CUDA / Open CL stuff the video card is not gonna consume this much, and also cpu is unlikely to be near 100% all the time. so you should be fine with it. If you want to double check my numbers, you can buy one of those power meters and see how much the computer actually consumes: kuman KW47-US Electricity Usage Monitor Plug Power Watt Voltage Amps Meter with Digital LCD, Overload Protection and 7 Display Modes for Energy Saving (NO-Backlight), white - - Amazon.com Amazon.com: P3 P4400 Kill A Watt Electricity Usage Monitor: Home Improvement These will report how much power (watts) the power supply takes from the outlet, which will be a number higher than what the components actually consume. Considering the power supply is 80+ standard, so only around 80-85% efficient, you can simply take that number and multiply it by 0.85 to get the amount of watts the components actually consume. So for example, say you start your rendering software or whatever and start doing something very intensive and you see on the meter 300 watts. That means that out of 625 watts possible, the components only consumed 300 watts x 0.85 = ~ 260 watts. That's not even half the capabilities of the power supply.
This doesn't alter the idea that it lacks an appropriate name.
