Apevia ITX-PFC500W Mini ITX/Flex ATX / 1U 500W Fully Modular Power Supply, Full Range Active PFC 90-264V, AC for POS AIO System Desktop Gaming Server Small Form Factor (Flex ITX) Computer PSU

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.

It powers my pc with no issues.I am very happy with this PSU, it saved me from having to buy a janky pico power suppy and then have an external power brick, which is less than ideal. I really like that its modular, less cables if you dont need them. The fan is quiet enough, tho i did switch it for a noctua one (because why not).The only thing i dont like is that theres no efficiency info, and thats something i always appreciate having.But overall, its a decent price for the size and build quality, I would recommend.

Using with optiplex 5050 sff, minisforum deg1 dock and rx 6650xt egpu setup.No complaints, and it's fully modular!! Great job !!

Causes system errors. Overheats. Extremely loud fan. Cable length for 8pin cpu is short.I was using the 500W power supply for a 350W system, when maxed out, and it kept crashing and causing BSODs.Spend extra and get something better

Only running the motherboard now, plan to add GPU later. Probably pulling around 150watts and this thing gets pretty warm. I haven’t smelled any burning electronics and it’s been working under different loads for a week now without issue. The power connectors are an extremely tight fit on the board, other 24pin connectors aren’t as tight fitting as these.It heats my SFF case up quite a bit. It’s definitely a hot running unit and I’m not running much power on it. But it’s working for now. Good enough until I get something better.

Needed a small PSU to fit in a JONSBO NV10 case. Measured it, to compare it to the sizing listed on their website, and this power supply is able to fit, no problem at all. Allowed me to complete the process of finishing my small build. Thank you for having this available.

Worked great on our mini build

Great for a SFF or low power draw build. 400w and 500w models have given me 0 issues.
