FSP Dagger 600W SFX PSU Review

The FSP Dagger 600W SFX power supply has been a rather disappointing unit to test. SFX power supplies are in short order on todays market, but I find it difficult to recommend this unit to any of our readers if I was being perfectly open and honest.

We like the fact that FSP have opted for modular cabling as it makes system builds into restrictive chassis much easier when it comes to routing. Not only is the cabling good, but even though the fan inside this power supply is small, it is well tuned to keep noise emissions as low as possible, without causing any issues.

First impressions weren't entirely positive however as the chassis scratched very easy, with wafer thin paint work all to eager to show silver underneath. I would expect greater quality control from FSP actually as I feel this power supply will scratch during a build phase, if extra special care is not taken by the user.

The 3.3V board inside the unit has a problem which gives us concern as the unit failed the ripple suppression test, one of the few we have had in to test that has hit 70mV at full load, well outside industry rated tolerances (50mV maximum). Surprisingly the +12V rail held up pretty well in our tests.

The unit is quiet under most conditions which means it will be ideal for people running in noise sensitive environments such as a bedroom or living room.

I was also a little unhappy to see only 2 PCI-E 6+2 pin power connectors available. I appreciate that this is an SFX unit and there are some compromises to be made, but there are situations that a user may wish to equip his or her system with two mid/high range graphics cards in SLI or Crossfire. 600 Watts is more than enough power to drive a powerful SLI system in 2017.

Another issue right now is availability in the United Kingdom. I asked FSP about this and they told me it is currently available in America. You can buy it from Amazon in the USA for $109.99 HERE.

As it stands, I would recommend the user base to check out the Corsair SF line as they are technically superior and easily available.

Pros:

• +12V ripple suppression is good.
• Load regulation.
• Quiet under most situations.
• Fan is pretty good.
• Modular design.

Cons:

• +3.3V ripple suppression fail.
• only 2X PCIe connectors.
• Finishing is very poor.
• CapXon polymer caps.

Kitguru says: The FSP Dagger 600W looks good on paper. Its an SFX design with Japanese primary cap, 80 Plus gold rated and is equipped with modular cables. In the real world there are some technical issues that make it very difficult for us to recommend, even if you could find it in the UK.
