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.

Effective amount of power for my SFF build with a modest graphics card (RTX 3050 low profile). Only note here is that if you are using this PSU for a Core Ultra motherboard, look closely at your motherboard before ordering because many of those have 2x 8pin (4+4) CPU power connectors and this only has one of those built in. Easily fixed if you notice this, however, as you can order an adapter to change one of the PCI-E power cables to another 4+4 CPU one.

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.

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.

Great value for the money, has been powering my SFFPC build since August of 2024. I have had no issues powering a Ryzen 5 2600X/Radeon 5700XT system and a Ryzen 9 7945HX/Radeon 5700XT system with this PSU.Included cables are nothing to write home about, all black, cheap feeling, and a bit long for most SFFPC cases but that length may be needed in a server chassis. includes everything you should need, nothing more. I cannot provide definite efficiency ratings but the power it pulls from the wall was not too far off from the reported load in Linux.The fan is acceptable in rack mounted applications but for running any sort of heavier load while at a desk, it becomes rather disturbing. The noise easily surpasses my GPU and CPU fan noise but became much more manageable after swapping to a Noctua A4x20 FLX fan (which comes with the needed adapter to mate to the OEM 2 wire cable). Before and after the swap, the housing still is toasty to the touch, probably in the 40-50c range.

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.

Works well for my sleeper optiplex gaming rig. Would recommend this to a friend who needs an affordable PSU in a slim configuration.

I have two Apevia PSUs, this one and a 600W SFX model, and I find them to be very reliable and very reasonably priced, especially for budget PC builds.
