I was afraid the cooling fan would sound like a 1u server turbojet and thankfully it's extremely quiet at idle and at low load, basically inaudible.
I'm replacing the stock 255W PSU in my dell optiplex 9020 sff and it's just as quiet as the stock psu, my power draw requirements are about 260W, so your mileage will vary.
Note that for Dell Optiplex SFFs you will need a ATX 24-pin to Dell 8-pin motherboard adapter and an extension cable for the ATX CPU 4+4pin because the cable length is not long enough for cable routing as is.
After using it for a month, I can say I'm quite satisfied with the build quality and quiet operation, the power headroom it provides along with the improved airflow makes it a must for anyone trying to max out the upgrade path on their prebuilt SFF PCs.
Initially, I bought it to improve airflow in my cramped case and give me a real upgrade path to a >75w GPU down the line and it does both of those things really well, airflow improved so much that I can't even hit thermal throttle anymore.
I did eventually end up upgrading to a 115W GPU and thankfully it's still just as quiet.
The modular cables feel sturdy, they're stiff but give way when bending and attempting cable management.
In my particular application, I wished the P4 4+4 pin CPU cable was slightly longer, I redid my cable management with an extension cable because routing through the RAM slots was bending the cable connectors at hard angles which I wasn't satisfied with.
In my optiplex, the space left behind by the old PSU was enough for stuffing excess cable lengths underneath and out of view.
By pure chance, the PSU slots in and lines up with a single screw hole where the old one went, you should get creative if you're not dealing with a standard SFF case.
