Wasting Money on Power Supplies: How Many Watts You Need for a PC PSU (2020)
We're testing how many watts you need for the average PC build, testing system load versus power supply 'size.' We're looking into how big a PSU is needed for gaming & work PCs in 2020.

This is more about providing hard numbers for existing builds and less about concept, but the concept is simple: You can always do this on your own by adding two reliable sets of GPU and CPU-only numbers (not total load numbers), then adding some buffer for other parts. In that sense, you don't really need a power supply calculator and can probably do it more accurately on your own.
Methodology used stems from our CPU & GPU testing methods (published earlier in the year in our methodology pieces — it's all the same parts). We describe verbally in this content whether we're using CPU or GPU graphics settings. Motherboard was a Z490 Maximus XII Extreme for Intel, X570 Master for AMD. The VRM efficiency will impact power needs as well, but ultimately, it's the GPU and CPU driving most of the power in the standard gaming PC. You will need to consider hard drive power consumption if running a large storage array.
Making a sweeping generalization here, we've noticed that a lot of people over-buy their power supply needs, and we'd assume that's because it's the safe thing to do. That is, «safe» with regard to ensuring no issues arise from buying too close to the PSU capacity. It's also the safe thing to do when you don't really know how to measure power supply needs. For the most part, you can take our component-level reviews (e.g. 10900K or 3900X review, or similar, and a 2080 Ti review, or similar) and add the two major parts' individual power consumption numbers to approximate the bulk of the PSU needs under full load. That's because we don't test total system power consumption for component reviews, but rather the power needs of that one component. In the instance of this specific video, though, we are using total system power consumption, and we're using that to measure the performance of a few builds we think are likely to occur in the 'wild.' That said, if you have minor component differences, you really should just be looking at power consumption numbers on a per-component basis and roughly adding things together. Or, if looking at the systems outlined in this video, you can extrapolate the jump between one CPU or GPU and the next and approximate the power needs much more accurately. Rather than using a «PSU calculator,» we think you should just actually do your own calculation by using data provided. In this instance, however, we've done most the legwork for common configurations to answer the question of how many watts are needed for a gaming or workstation PC's PSU.

In this video, we're recapping custom video card designs (as we know them today) from EVGA, MSI, Zotac, ASUS, and Gigabyte. We're still waiting on a ton of information — especially since nearly half of these partners had broken websites — but we can get a head-start on what's coming to market. This includes a look at the EVGA RTX 3090, 3080, and 3070 series, like the FTW3, Kingpin, Hybrid, and XC3, the Zotac Trinity and HoloBlack designs, ASUS TUF, Strix, and Dual RTX 3080/3090 designs, and Gigabyte's extra fat Xtreme design.

В России построили новую школу и это впечатлило меня настолько, что мне захотелось с вами поговорить об этом в видео. Часть про Nvidia мы вырезали, про нее поговорим, наверное, завтра — уже в отдельном видео. Немного поговорим о новой системе охлаждения AMD в Radeon RX 6000. И о прошедшей презентации Apple.
