FSP FlexGURU Power Supply, Flex ATX 300W, 80 Plus Gold, Full Modular (FSP300-57FCB)

Small, quiet PSU for my Mini-ITX PC

Historically i've avoided any computer case that needed a flex ATX PSU. I just have had bad experiences with them being super noisy when u draw a lot of power. The FSP Flex ATX 300W PSU surprisingly changes the game when it comes to my experience.Pros - What more can I say aside from this thing is silent, I have it running in my server with 8x 3.5mm HDD"s running proxmox and it is silent, not a peep.Cons - wish it had a 6 or 8 pin VGA power connector to at least put in a low powered GPU into my rig, guess my RX 6400 will have to do for now.Other than that it does what you expect, provide power to your system, tho I wish it was 80+ platnium or at least gold, bronze is meh.

I bought this FSP power supply for use with a Mini-ITX build in a small case. The power supply is nice and small, and that made it easy to install. However I do have a problem with the "modular" description, because it really isn't modular in the same sense as regular ATX power supplies. With regular ATX power supplies, you have multiple sockets on the power supply to plug in only what you really need. The issue with this FSP is that it only has 3 sockets; two of them is for the 20+4 and 12v wiring harness (a combined harness). That leaves one socket for peripherals like SATA and these cables are all multi-plug, so there is no real "modularity" since you still have to plug everything in. I'm only using one SATA drive and I have to use a long cable with 3 SATA power plugs on it! Aside from that, so far the power supply itself has been running good. The fan noise is low, a standard Intel CPU cooler fan is louder in comparison.

Been using this in a NAS for months with no issues. Would definitely buy again.

I used this for a four bay NAS with an ITX motherboard. Worked perfectly. The modular cable system was perfect for working in such a small form factor. I would buy it again for a similar project.

The media could not be loaded. I bought the modular 300w power supply from FSP. The fan is very quiet.Please note, the 300 watt version does not support 8-pin GPU power (unless you adapt power from the SATA/Molex cables). This unit simply powers your motherboard, cpu and drives.This PSU provides more than enough power for my system, which spikes at 210 watts.System Specs:Intel Core i5-13400Noctua NH-L9iB660I AORUS PRO DDR4FSP FlexGuru 300WNvidia RTX A2000 (draws all power from the motherboard)Kingston FURY Beast DDR4 3600MT/s 2x8GBSamsung 980 Pro 2TB

using this to replace cheap 400W power supply. My computer is working now

Pros-80 Plus Gold-Size (my use case)-Modular cablesCons-Fan is noisyPowers a Minisforum BD795i SE and one M.2 for 24/7. The 24 pin motherboard and 8 pin cpu connector are on the 14 pin and 6 mini pin PSU connector (SATA and Molex is on the 10 pin). Power load is 0.5-130 watt and I have no complaints other than fan noise...
