It’s almost impossible to find a non-modular 850W PSU. But some manufacturers design semi-modular ones which are affordably priced. Plus Titanium is about as good as you will get from consumer power supplies and Gold is pretty much slap-bang in the middle. But looking at the table above, the actual differences between each grade are small. FSP includes the following cables with the Dagger Pro SFX:

You've got the choice of 550W, 650W, 750W, and 850W capacities, which makes this a good choice for modern GPUs like NVIDIA's RTX 30 series. The 80 Plus Gold certification means you can expect to enjoy high levels of efficiency that result in less waste heat inside the chassis and lower power consumption at the wall.

But some manufacturers also design them in white colors to cater to builders looking to build sleek, all-white gaming PCs. This is why we don't go too in-depth, especially with power supplies. How we test units involves connecting one to a reasonable load and seeing how it performs in a variety of test scenarios to represent how they would be used by owners. After putting the Dagger Pro 850W SFX to the test in a system with an AMD Ryzen 9 5950X CPU and NVIDIA GeForce RTX 3080 GPU, we encountered no issues. The FSP Dagger Pro 850W PSU is a great option for anyone wanting to put together a compact PC. If you plan on using a smaller PC case that only takes an SFX or SFX-L PSU, you'll need to use such a power supply. You can do much worse than the Dagger Pro 850W, and it's absolutely possible to choose a unit from an unknown brand that runs the risk of frying your expensive components. 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.

We waited years for a competitor to dethrone Corsair's AX1500i, and in the end it was another Corsair power supply to post higher overall performance. The Corsair AX1600i is the best PSU that money can buy today, period. It offers top performance in all areas and uses an innovative platform, which provides a glimpse at the future of power supply design.

Semi-modular PSUs have only the most important cables attached, with room to add extra cables as needed. You’re more likely going to need an ATX power supply. That’s unless the case manufacturer specifically states you use an SFX one. Modular Design

To be 80 Plus certified means that the PSU has at least 80% efficiency at three load levels of 20, 50, and 100 percent loading. I recommend getting a fully modular PSU since it offers total control of your build’s cable management. Efficiency Rating

Overview

ATX 3.0 is the new specification standard for PSUs. This new design adds a new PCIe 5.0 connector with 12 + 4 pins alongside the usual 6 or 8-pin connection.

My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads. Pros: Since the new era GPUs require more power— especially the RTX 4000 series, an ATX 3.0 PSU ensures your build is future-proofed for power-hungry GPUs. ColorAs always, buy sensibly. Over-speccing a PSU makes more sense at the low end, where quality differences are more readily apparent. If you're running an extremely high end system, a 100-200W buffer on the high end is sufficient. For as much time as they'll spend near the "sweet spot" of that efficiency curve, they'll spend just as much time on the low end of it during typical idle or desktop usage.
