Besides the totem-pole PFC, the AX1600i also uses two Digital Signal Controllers (DSCs) to manage its circuits. A single microcontroller (MCU) is the communications bridge between the system and the PSU, allowing users also to control some vital functions of the PSU (for example, the fan speed profile and the selection between multiple and single +12V rails, setting up the OCP limits, etc.) besides monitoring tasks. In Doom Eternal, power usage slightly increased to 471 Watts, situating the 4080 between the 3080 and 3090, but still reducing total system usage by 22% compared to the 4090. Similarly, in Hitman 3, power usage remains lower than the 3090 and comparable to the 3080. Additionally, if you’re aiming even higher and have a 750W PSU at your disposal, the mighty RTX 4090 is the way to go. The RTX 4080, part of the GeForce 40 series, is a high-performance graphics card based on the Ada Lovelace architecture. For a PSU to convert AC to DC, heat is produced from the internal components, which is where some efficiency is lost. The sweet spot for a power supply is considered somewhere between 40% and 80% load, though according to official numbers from various manufacturers, this can differ from PSU to PSU.
On the other hand, if you care more about your electric bill or the environment and plan to maintain higher CPU or GPU usage, a more efficient PSU may be better. As I became more conscious of my electric bill and environmental impact, I observed that my high CPU and GPU usage took a toll. So I researched and analyzed my options. Based on my findings, I invested in a more efficient PSU. It was a decision that paid off, as I saw a noticeable decrease in electricity costs over time. The fan in the Supernova GT, a 135 mm model with Fluid Dynamic Bearing (FDB), should ensure smooth running and also keep durability high. Pros

EVGA is one of the top providers of graphics cards and power supplies in the USA and has made a name for itself, among other things, with its Step-Up program, where you can upgrade graphics cards to better models for an additional fee. Recently, EVGA has also become more active again with mainboards, which made us very happy, because to this day we have some EVGA celebrities in our editorial office, such as the EVGA X58 Classified 4-Way SLI, which was one of the best and most complex X58 mainboards at the time the market. If you’re really trying to maximise the visual appeal of your build, a modular power supply is almost essential – you can avoid all of those messy looking wires cluttering up your case. The NZXT E650 takes things a step further. Not only is it a fully modular power supply, meaning you only need to connect the wires you actually need, but it’s also extremely attractive itself, begging to be shown off in your case. This is all topped off with an 80 Plus Gold efficiency rating and a 10-year warranty – not only will it look good, but it’ll deliver power efficiently and last forever while it does it. How do I choose a PC power supply?
Cougar BXM700 is an incredibly well-built 700W PSU for high efficiency, reliability, and value! It combines a DC-DC technology with a 135mm HDB fan for a stable power supply and effective quiet cooling. It’s built with high-quality internal components to reliably power high-performance gaming systems on a budget. It is a non-modular unit with an 80+ Gold certification and over 90% efficiency under typical loads. Pros: The non-modular cable design won’t please most users, but modular cables would notably affect the final price, so they had to go to. Given the not-so-high number of cables in this PSU, the non-modular design isn't the worst. Thankfully, the five-year warranty that XPG provides is the cherry on top of this product. The FX Pro range are 80 Plus Bronze certified achieving an efficiency of up to 88% at a load of 50%. Consider upcoming GPU power requirements. Although the best graphics cards are usually more power-efficient than previous generations, their power consumption increases overall. This is why the latest 12+4 pin connector that the upcoming generation graphics cards will use will provide up to 600 W of power. Currently, a pair of PCIe 6+2 pin connectors on dedicated cables are officially rated for up to 300W, and three of these connectors can deliver up to 450W safely. You should also add the up to 75W that the PCIe slot can provide in these numbers.

When building a PC, I can't stress enough how crucial it is to choose the proper power supply. It's essential to provide stable and efficient power to your computer's parts, protecting them from power fluctuations and ensuring your system's longevity. I have experienced the consequences of an inadequate power supply and can tell you that it's not something you want to risk. The power draw of around 350 Watts is decent, representing a significant improvement over previous AMD cards. Once you've found out the wattage you'll need for your PC, you'll need to decide what efficiency you can afford. Power supply manufacturers all tend to agree to the same PSU efficiency rating system: 80 Plus.
