FSP introduced its Dagger family of SFX PSUs for gaming systems at Computex 2016, about nine months ago. However, sometimes it takes several quarters for products to reach the market after their formal announcement because makers finalize certain details. This week, the company announced pricing of its SFX PSUs, an indicator that they are going to hit the market shortly.

As reported, the FSP Dagger lineup consists of two models rated for 500 W and 600 W maximum load. Both PSUs are compliant with the SFX12V V3.3 and ATX12V V2.4 specs as well as carry the 80 Plus Gold certification. The Dagger power supplies have modular design and come with EPS12V power connectors (one 24-pin and a 4+4-pin connector), two PCIe 8-pin (6+2) power connectors to support all existing graphics cards as well as the upcoming GPUS, as well as five SATA power plugs. For cooling, both PSUs are equipped with an 80 mm dual ball bearing fan.

FSP will offer the Dagger 500 W for $99, whereas the Dagger 600 W will retail for $109. MSRP of FSP’s 500 W SFX PSU is in line with prices of competing devices of the same wattage, whereas the 600 W is slightly cheaper than the rivals are.

ATX 24 Pin - 1
EPS 4+4 Pin - 1
PCI-E 8 Pin - 2
SATA - 5
Molex - 2
Floppy - 1

It is noteworthy that over the past several quarters, three PSU manufacturers have announced their SFX PSUs for miniature gaming systems. Enermax, FSP and Thermaltake are joining the club, which originally only had Corsair and SilverStone a year ago. This is not exactly surprising, as miniature gaming PCs are getting more popular. Virtually all makers of high-performance computers offer small-form-factor gaming systems, and there are a number of newcomers that exclusively build only SFF gaming machines. While initiatives like Valve’s Steam Machine has helped bring some systems to market, others like Corsair’s Bulldog and One aim to bring a gaming PC into to the living room. Obviously the DIY market follows the industrial trend and demand for various components for mini PCs is on the rise, which is why five makers now offer SFX PSUs.

Most vendors stagger their PSU launches based on region, and we expect FSP to do this as well.

    I'm kinda curious what the accessory cables look like. 5 sata and 2 molex on two strands is a bit of an odd combination. All the sata's on one would be way more cable than most SFX builds need. Splitting the satas 2/3 would work reasonably well, but leaves the question of if they stuck a molex on each cable or are using SATA to Molex adapters similar to how most PSUs offer a single Berg connector for a floppy. I've seen a few of the latter but never in a standard accessory pack before

    It's nice that companies are making (or at least marketing) more SFX PSUs these days--Corsair started in on this, and now there's new FSP models (who'd been marketing and OEMing SFX supplies for some time).

    I remember back in the Core2 days when [good] SFX supplies were few and far between. I have a few now-old Enermax units that were pretty good. Back then they had units that were 250W, 270W, and 320W--older group regulated units no doubt an an efficiency range of like 70-80%, tops. Well outdated by today's standards, but still decent supplies for their size.

    The 'problem' with these newer 500W+ SFX units is...what's the point *now*? These days 500W is enough to run a 7700K and a GTX 1080 (and it's not like you're gonna be making an SLI machine with the single-slot ITX boards most of the cases with SFX supply requirement accomodate).

    The other thing is, pretty much all the mATX cases out there these days support ATX PSUs; and, a great deal of ITX cases support full ATX units as well.

    It boggles the mind that PSU makers are now pushing the "number of Watts" capacity into these tiny little units in an age where PC components are continually taking less and less power as time goes on. These (and other high-wattage SFX supplies) would have been more appreciated in the C2Q or Bloomfield i7 days with GPUs like GTX 470/570/580 and HD 5870. Today though? Today we could go back to the 320W units, just with DC-DC and Gold or better efficiency, and it'd be a much better idea.

    A Ryzen 1800X at 4 Ghz with an overclocked GTX 1080Ti and Nvme SSD with a mini ITX motherboard can suck up to 450-500 watts at full load

    LOL Ryzen, nobody buys Ryzen for gaming.
