FSP has introduced its first power supplies in SFX form-factor designed for high-performance gaming PCs. The new Dagger family of PSUs will contain 500 W and 600 W models that feature a modular design 80 Plus Gold rated. With this latest PSU release, FSP will join a very narrow crowd of PSU makers who build SFX power supplies for gaming PCs.

When it comes to high-wattage SFX power supplies for gaming PCs, the users have a choice between only two major brands: Corsair and Silverstone. While these companies are well known and are very respected by the DIY community, the lack of serious competition has its effect on prices, which is why SFX PSUs are rather expensive for their wattage. FSP, the new kid on the block, will become the third major brand to offer SFX power supplies for gaming systems, which is a positive thing for the market.

The FSP Dagger family will initially include two models rated for 500 W and 600 W maximum load. Both PSUs are compliant with SFX12V V3.3 and ATX12V V2.4 specifications as well as carry the 80 Plus Gold certification. Both PSUs will be equipped with an 80 mm dual ball bearing fan and both feature modular design to ensure easy cable management and clean system builds. Finally, FSP claims that its Dagger PSUs sports a special cross-regulation mode to handle unbalanced loads, which are common for some gaming PCs.

FSP Dagger Series
Connector type Hardwired Modular
ATX 24 Pin - 1
EPS 4+4 Pin - 1
PCI-E 6 Pin - 2
Peripherals - ?

The Dagger PSUs will have EPS12V power connectors (one 24-pin and a 4+4-pin connector), will sport two PCIe 6-pin power connectors as well as several SATA power connectors. While it will be possible to use such power supplies for systems featuring high-end graphics cards that only have one 8-pin PCIe or two 6-pin PCIe auxiliary power connectors, the FSP Dagger PSUs will not be able to work with graphics adapters that require two 8-pin PCIe inputs (from formal point of view, of course). For example, NVIDIA’s GeForce GTX 1080 has one 8-pin PCIe auxiliary power connector, which can be plugged to two 6-pin PCIe connectors using a special adapter. Meanwhile, AMD’s Radeon R9 Fury X uses two 8-pin aux PCIe power inputs, which is why it is formally incompatible with the Dagger.

The Dagger power supplies from FSP will hit the market later this year. Right now, prices of the products are unknown.

    "High-Wattage"
    (...)
    "500-600W"

    Well.. I know SFX PSUs have typically lower wattage, but at least on ATX terms that's "mid-wattage" at best.

    It's more than enough for almost any single-gpu gaming system (and many multi-gpu systems), so I think it's alright to use the term "high-wattage" since it's in the context of gaming machines (add stated in the sentence before the "high-wattage" sentence).

    If you open up the use case, then obviously that's no long terribly high wattage.

    I guess the bottom line is that it's not egregiously wrong enough to correct.

    I'm not questioning the amount of PC system variations where a 600W PSU is "more than enough".

    I'm questioning the fact that a 600W is being considered "high-wattage".
    If 600W is high-wattage, then what is 850W? Extremely high-wattage?
    And 1000W? Super-Extreme Wattage?
    And 1200W? Ultra Super Duper Wattage?

    If we look at the PC market in general, then 500-600W is "mid-wattage" at best.

    I think 600W is the highest available value for an SFX PSU. Reply

    700W SFX-L is available from Silverstone (shipping to distributors now), 750 from Lian Li (shipping to consumers now in the US) and Silversont have just announced an 800W SFX-L PSU. Reply

    Not to nitpick, but SFX and SFX-L are two different beasts. When your ITX case only supports SFX, those SFX-L bricks are as useless as a full ATX power supply. Reply

    For SFX, this is Ultra Super Duper Wattage.

    I don't believe beyond 600w if even available. You are talking something < half the size of an ATX PSU.

    I see where you're coming from.

    I suppose I limited my scope to gaming machines because gaming machines were particularly called out early in the article and a name like Dagger lends itself to that sort of thing.

    But if we're opening up our scope to other use cases, then I could see that terminology as being more reasonable.

    For any system that requires a SFX power supply, 600W is certainly high wattage. Mini-ITX cases that can't fit SFX-L or larger are quite cramped. Even if you managed to fit a healthily overclocked i7 6700K, GTX 980TI, 4 DIMMS of RAM, a pair of 7200 RPM hard drives, 4 SSDs, and a half dozen fans all crammed into a case that can only accomodate a SFX PSU, your 600 watts would still have 75-100 watts of overhead at full load on all components.

    The article always says "high-wattage SFX", though, which is pretty clear. Reply
