Information technology's a brand that isn't peculiarly renowned for making the best ability supplies, simply the company really does just that past making PSUs for the likes of EVGA, Cooler Main, amid others. We're big fans of EVGA hardware and so were excited to become concur of FSP's own Dagger Pro SFX PSU.
Small grade factor (SFX) power supplies are designed for use in more compact PC cases. The major difference betwixt SFX and total ATX power supplies is size. SFX units usually come in at 125mm ten 100mm with a height of simply 63.5mm. That's precisely where you'll detect the FSP Dagger Pro 850W SFX PSU we accept for review today.

Yous can find the FSP Dagger Pro 850W SFX PSU for effectually $200. This is quite the hefty cost to pay for the capacity, but this is the cost of SFX PSUs, which frequently command premiums compared to standard, larger ATX units. It's a pretty good listing toll to put it in line with competitor products, including the excellent SilverStone SX800-PT.

FSP makes some dandy PSUs for other brands and so nosotros expected to see some first-class performance from the SFX series of FSP Dagger Pro power supplies. The range starts at 550W and goes upwards to 850W in increments of 100W, providing a strong selection for anyone looking to build a compact PC.
550W is still good plenty for many PC builds, though 650W should exist considered for RTX thirty-series graphics cards. The unit we received for review was the range-topping 850W. It rocks a single 12V rail that can handle upwards to 54A of ability draw, which is more than than plenty for even more enthusiast-grade components.
Matching the SFX standard dimensions, you'll have no issues fitting the FSP Dagger Pro SFX PSU into the almost compact PC cases.

The 80 Plus Gold certification merely really determines the level of efficiency a PSU should achieve. The Dagger Pro nosotros're reviewing hither is 80 Plus Gold, which means it should be around 92% efficient at l% power load, which is where you should aim for with your PC components. The less rut waste material produced, the less ability required from the wall.
| Load | 80 Plus Bronze | 80 Plus Silvery | 80 Plus Golden | eighty Plus Platinum | fourscore Plus Titanium |
|---|---|---|---|---|---|
| 20% | 85% | 87% | 90% | 92% | 94% |
| 50% | 88% | 90% | 92% | 94% | 96% |
| 100% | 85% | 87% | 89% | 90% | 94% |
fourscore Plus Titanium is about equally good as you will go from consumer ability supplies and Gold is pretty much slap-bang in the middle. But looking at the table in a higher place, the actual differences between each course are small-scale. FSP includes the following cables with the Dagger Pro SFX:
- 1x 24/20-pin ATX
- 1x 8/iv-pin EPS/ATX 12V
- 1x viii-pin EPS/ATX 12V
- 2x eight/6-pin PCIe
- 2x SATA/MOLEX
I also appreciated the SFX to ATX subclass included with the PSU, just in example yous needed to use it inside a larger PC case. The majority of PSUs nosotros test laissez passer with flight colors, and while we could become all-out with a digital oscilloscope to actually dig deep into the power figures, so long as the unit is able to perform reliably in real-earth conditions, that's what really matters to consumers.
The FSP Dagger Pro 850W SFX lets you lot build a powerful compact gaming PC.
This is why we don't get too in-depth, specially with ability supplies. How we exam units involves connecting one to a reasonable load and seeing how it performs in a multifariousness of test scenarios to represent how they would be used past owners. After putting the Dagger Pro 850W SFX to the test in a organisation with an AMD Ryzen 9 5950X CPU and NVIDIA GeForce RTX 3080 GPU, nosotros encountered no issues.
The examination bench was used to process and render video, run constructed benchmarks for prolonged periods of time, and play some demanding games like Grand Theft Auto v, Cyberpunk 2077, and Mount & Blade 2: Bannerlord. The power supply fan kicked in, but it's barely noticeable over two fans running to keep the Ryzen nine processor cooled with an AIO. Software monitors showed stable power commitment to the well-nigh disquisitional components, which was expected and is swell news for the PSU.

There's not really much to dislike almost the Dagger Pro 850W. In terms of pricing, it'due south expensive for a PSU, simply it's in line with the competition, if non more than affordable. For 850W of stable ability in a compact class cistron, yous should look to pay a small premium. The fan tin can besides ramp up and make some racket, though yous'll be hard-pressed to hear it during normal operation.

A close contender to the FSP Dagger Pro is the SilverStone SX range of SFX PSUs. Nosotros reviewed the SilverStone SX700-PT, which was very skillful thanks to the high-quality components and excellent performance. Information technology was allow down by the limited warranty and 85C-rated capacitors.
FSP includes a seven-year warranty with the Dagger Pro 850W, which is pretty skilful at this cost range. It too also has high-quality Japanese capacitors, which is what you want at this price. The fan is good enough to keep the temperatures downward, even when going all-out with upward of 600W of power draw.
The SFX market of PSUs is a trivial more limited than full-size ATX units, but there is a solid choice out there with these ii PSUs as fine examples.
