FSP Dagger 500W Mini ITX Solution/SFX 12V / Micro ATX 80 Plus Gold Certified Full Modular VR / 4K Ready Gaming Power Supply (SDA500)

I used to have an OEM 250W power supply in my mini-ITX case that came with the case when I purchased it. When I added an external graphics card earlier this year, I quickly realized I needed to upgrade my power supply to match. I looked to see if I could find something from Corsair, Seasonic, or one of the other brands I know and trust. When I saw this FSP unit, I remembered how they used to supply power supplies to manufacturers like Compaq in the servers I worked on in datacenters in the nineties. That was enough for me to pull the trigger, especially considering the very reasonable price. I'm very glad I did!There were several upsides to this upgrade:1. With the original PSU, my average power consumption whilst doing very basic tasks would be about 60W, as measured with my Kill-a-watt power meter. After upgrade, that dropped to less than 45W!!! That's an efficiency increase of 25%, which is just silly.2. The fan in the old power supply was running all the time, at a noticeable level. New power supply fan doesn't kick in at all, unless I ramp up CPU usage to 100% for sustained periods (rendering video etc).3. The heat generated by the old PSU was palpable. Post-upgrade, the temperature in my office has dropped by several degrees! The new power supply is hardly even warm to the touch where the old one was hot! This is due to two things - having the extra 200W headroom, as well as the Bronze 80 certification. This is a guarantee of at least 80% efficiency in the conversion of mains AC voltage to the PC's 12V, 5V, and 3.3V feeds. There are four rating levels - bronze, silver, gold and platinum. I will never again buy a PSU that is not 80+ rated.This is a GREAT little power supply, and I am very glad to see that FSP are still making the same quality of equipment after all this time.

A well-built power supply unit with a loud fan.If you haven't heard of FSP or their reputation as a power supply builder, that's okay because most people haven't. FSP is the OEM of OEMs, meaning that they normally create the power supplies that go into OEM's systems like Dell and Lenovo, as well as developers of other power supply manufacturers like Thermaltake and Cooler Master.The unit itself delivers clean power. I was pleasantly surprised to find that the unit is painted black, considering that I was expecting this to be a silver "OEM"-style unit, and that it even has a power switch! FSP's soldering is impeccable, at least on this unit. I've had this supply on for several months without stop, and it hasn't taken out my computer yet, which is a good thing.Whenever dealing with small form factor, heat is a large factor, and noise is a large factor with smaller fans having to spin faster to move the same amount of air. Unfortunately, FSP chose to use a particularly loud fan. Additionally, some of the wires are longer than others and are tangled with no way to tidy them without complete disassembly and desoldering. If this is a rig that you're going to be looking at, get sleeving.Pros:-Clean power-Black paint job-Clean soldering-DependableCons:-Loud-Poor cable managementConclusion: if this is going in a computer that you won't be seeing and you wear headphones, this is a neat little power supply. If the computer this will be powering has a window or you don't wear headphones, this might not be the product for you; I would recommend Corsair's SF400 unit.

Don't let that standard gray color fool you, this is a high quality PSU.So I've been using this PSU for exactly 1 month and absolutely love it. This is my second FSP power supply (the other is a different model in ATX format) and the brand is very focused on quality and details.It is true as others say: This unit is completely silent, i was really surprised by that. It runs cool and quiet.Bought this PSU for a custom case project with very little room and it has served it purpose so far. At the beginning i used the computer with the integrated graphics to allow the PSU to prepare for the hard work. After a couple of days i then installed a Geforce GTX 750 Ti and has been running great so far. Other PC components i'm using are: Gigabyte motherboard GA-B85N-WIFI, Intel core i3 4330, 4GB RAM, 2 SSD and 1 HDD. Other users are reporting far better hardware running on this PSU.This PSU is really quality oriented, you can tell that from the box which is pretty well printed with all specs and features. By the way the box says "Intel Haswell System Ready" in case you're asking if this PSU is Haswell compatible (not specified by Amazon).The unit itself is pretty sturdy with a thick case construction, it doesn't bend like other PSUs. Internal component seems to be pretty decent by the look of them (Hardware secrets website can confirm this).I was wise to bought this PSU with a 24 pin and 4 pin power cable extender, do yourself a favor and do as i did.UPDATE: It has been 2 years by now. Working great! still running cool and amazingly quiet.

Has all the power supply connections I needed for (Black Widow) my i9 9th - gen, 2060, 32gb with water cooling with RGB fans, and all LEDs throughout the mini ITX rig with consistent power in a small and sleek looking little box.Revised: It stopped working after a month. Produces only a fraction of the power which is not enough to turn on any of my components. Waiting on the seller to respond to my replacement request.

Good:A great small and compact size 300W PSU for space limited M-itx and MicroATX cases.Bad:Very short wires, better fitted for M-ITX or ITX board.I am using it on MicroATX board and microATX case, the cpu connector is about 2-3" too short, and it has too many older connector types that pretty much useless nowadays, it should have at least 2 more SATA power connectors.I also have to install the PSU with the fan facing upwards because of shorter wire, probably have to buy extension cords.
