Great modular PSU with a small form factor
I was on the hunt for a smaller PSU for my mATX gaming box. I paired this with a i5-9600k cpu and an Asus TUF GTX 1660 Super OC GPU. Love the modular design, will make hiding the cords easy. It is also quite. It comes with a plate to attach so you can use it in an ATX case, but check your sizes/cutouts of your case because it is a smaller form factor, ie the fan is smaller if you have a special cutout for a regular ATX sized fan, you may have gaps. It worked perfectly with mine. A bit on the higher price level, but I researched these fans and they are good quality with lots of good reviews. Highly recommend.

The 450 Arrived DOA, but ordered the 850
Unfortunately while testing before moving all components inside case the power supply was defective. No spinning fan, no clicks, no motherboard lights. Tested again with spare ATX and everything worked, returned and ordered the Dagger 850, hopefully I’ll have better luck this time, update, the dagger 850 works perfectly . So my advice stick with the Dagger series

You need an ITX power supply? This is it
Great little ITX power supply. No complaints. It’s been running for a few weeks now.

Garbage
Died within 4 months of use. Turned PC on as usual, *pop*, dead. All cables were properly seated and I only used the ones included with the PSU. Just glad it didn't fry my new PC. Stay away.

Not modular. But decent itx psu.
Decent itx psu. They must have cut and pasted the description from the higher wattage variants. Met my needs for a small apu system.

Works as intended.
Works as intended, turned out it was bad CPU out of the box, not this PSU

Good PSU from a Great Company
FSP powersupplies are the only PSUs i've ever used. This is nothing short of the best. It's actually rated for it's advertised wattage. They are more expensive then other companies, and there's a reason. They are pretty much the only company that has any buisness being in the Powersupply game. Pros- SFX for Itx Builds, modular, 650w 80+gold, fan is quiet, and isn't even on until it starts heating up, which only happens of you're pushing it. Cons-Cables are way too long. The CPU 8pin is 700mm long, which is absolutely insane for an ITX build. It also is an 8 pin, with a 2nd 4+4 attached to it, which is dumb, again because it's ITX and there is no ITX motherboard that uses 8+4 or 8+8. The sata cables are both molex, and one has a floppy connector on it, so if you're running hardware that old, i guess thats okay. But again it's an ITX PSU, so there is once again no need for a 700mm cable with 100mm of cable between each connector. Other than that no problems.

Compact!!!
Lovely PSU fan. It significantly reduces the weight of a mini ATX build. Less weight is needed, as I place my PC on my desk.

Bought this sfx PSU from a local retailer listed on Amazon.sg. Delivery was fast within 3 days. IT fits well into my small form factor rig. I tried those modular PSU which did not fit because of the larger plugs. This FSP psu is what I needed. Power up the rig and it was able the deliver the power. Will consider buying another one with a higher power wattage.

Ce PSU, malgré le fait que la marque soit peu connue, fonctionne très bien et il est très silencieux.

wow! its damn small @ 125*100*63 mm. and "silent" too. I will purchase another FSP SFX again, if they do a modular version of this.
