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.

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.

    There are 4-pin + Molex to 8-pin adapters.
    There are Molex to 6-pin adapters, and then fed through a dual 6-pin to 8-pin adapter.

    If adapters are fair game for "compatibility" purposes, then so are any other adapter besides a dual 6-pin to 8-pin adapter. As long as the PSU's wattage suffices and there's enough amperage on the +12V rail, then it'll run it, even if out of the box it doesn't have the connector types you need; you'd just need to spend an extra amount to get adapters for PSU connections you aren't using.

    Either way, it's pretty weird that it doesn't have a single 6+2 pin connector and that seems to be the "norm" for most high-ish performance gaming cards in 2016. Reply

    Especially at the 600W level. The only way you're going to get that high in an SFF system is with a big hot (and probably OCed for more power consumption) GPU that's burning through more than the 225W of power notionally available from a 2x6 pin cable.

    At the 500W level I could see them just having been caught flatfooted by the change (which could've happened a as many as a few years ago); although even then 1x6 and 1x8 would seem to be needed to handle the total power load.

    OTOH aren't most current generation PSUs now initially pure 12V and then using DC-DC conversion to make the 3.3/5V rails? That these models are talking about cross load protection makes me wonder if they're an early generation gold design stuffed into a small box; which would explain the 2x6 power outputs and potentially make worry about cabling for more 12V a moot point because their 12V max power is significantly lower than their total paper output (even though a modern system will rarely use more than a few amps of the low voltage power at all).

    Aw, I was hoping to see an SFX-L PSU. 120mm fans! Reply

    Corsair has SFX PSUs in 450W and 600W models that have a 92mm fan. Used it in a build I did a few months ago.

    Silverstone has a 700W SFX-L PSU. Reply

    Wow. 92mm in an sfx? I think I found my next psu. May even replace the stock fan with a Noctua NF‑A9x14 PWM fan for uber quiet running when the fan does kick on. Reply

    Is SFX-L an actual standard or just something Silverstone hacked together on its own? Reply
  • JoeyJoJo123 - Wednesday, June 01, 2016 - link

    Silverstone standard that Silverstone hopes catches on. It's not a terrible idea, though. But they're really the only ones that have done anything with SFX-L. Reply

    A bit misleading. FSP produced the first 450w consumer SFX PSU under Silverstone's label, the ST45SF, long before Corsair even entered the space. To cast the company off as the "new kid on the block" is astounding to say the least. Reply
