450W Mini ITX Solution/SFX 12V / Micro ATX 80 Plus Bronze Certification Power Supply (FSP450-60GHS(85)-R)

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 -Dependable Cons: -Loud -Poor cable management Conclusion: 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.

This fit perfectly in my ITX case. I replaced the stock PSU with this unit as the original sounded like a jet engine. This power supply has fantastic reviews at Hardware Secrets (rated Golden and confirmed 80%.) Go read the review there if you are not sure about the quality of this unit. This costs more than my ITX case with built in PSU but it's worth the money as far as I am concerned. Quiet, stable, reliable power is very important to me. This unit is VERY quiet. I can't hear it all. I had to verify the fan was actually spinning as it was so quiet. Here is the deal on this unit. This is designed for a small ITX case. The cables are very short. This would not work in a full size case without extenders or something. I wouldn't bother if you have a full size case. Get a different PSU that is designed for ATX. The use case is for low power, small ITX systems that need to be quiet. The cables just fit in my case and I was pleased to not have a bunch of extra wire I had to coil up. It does come with some legacy connectors that you will likely not use as well. Not a problem for me.

Bought the PSU 10 months ago, and for about 6 months it worked as expected. Quiet and reliable. At month 9, started making wining noises. At month 10, now makes clunking noises. Fan revs heavily up and down when PC is at idle with nothing running down. Reached out to product support over a week ago with no response (Their website says allow 24-48 hours). Called twice and went straight to voicemail.

Works great, as a power supply, but the fan is sorta loud.

been using it for the last 2 months ,so far so good. edit: April 9 20 , still working fine

As expected.
