ApeviaITX-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.

Works fine, it’s not that loud, at least not loud enough to bother me. I had to buy a second unit because I used a random power cable thinking it would work and fried my last unit. Don’t be like me, use what came with the unit (I got lucky that only the unit fried, it could have gone really bad).The cables are great quality. It’s a 1u size, fits in sktc cases.

The fan is a little loud but other than that, it works great! Able to power my Ryzen 7 5800X3D and RTX 5070 in a velka 5. The cables are a bit stiff for my case but I made it work. The gpu cable is a 6 pin to 2x 6+2 cable so I was able to connect the 12vhpwr cable.

This PSU silently killed two sticks of RAM in my compact build (i9-9900K, RTX 3070). After constant crashes and hours of diagnostics, I traced the issue back to this unit. Replacing it with a high-quality PSU (SilverStone FX600) resolved everything instantly.Apevia may advertise 500W, but the voltage regulation and power stability are terrible — especially for modern components. It’s not safe for serious builds and can cause real hardware damage over time.Don’t make the same mistake. Avoid this PSU.

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.

Great little PSU for my micro-ITX systems. I bought two of these PSUs for the 2U Rackmount Case for Dual Mini-ITX (Amazon product B0BJ6V89HD) -- so I have 2 independent systems in a 2U rack mount case. Works well, no complaints after a year.

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
