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

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.

Upgrade sff psu. Installed in an Optiplex 7040. Took some modification to the case, but who cares. Ditch the factory psu and put in a respectable gpu

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.

Is one of the few modular flex ATX supplies that is available in mid wattage range. Reasonable quality, well rounded construction, adequate cable length. The market for supplies of this type are thin, so one of the best sff options and it supports PCIE 8 pin!

The fan was constantly on while plugged in, which is just a mild complaint but within a month or so of using it, it's started just not deciding to work sometimes. I'll plug it in and get no power, trying multiple fixes to no avail but then several days later it'll be fine again. It gets rather loud too when it heats up, and it can get quite hot. Cables aren't what I'd call long but they weren't the shortest cables I'd worked with. I don't know if I just got a bad unit but the build quality seemed iffy at best. I'd avoid and go with a more premium option.

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.

After reading all the negative reviews about this PSU, I was uncertain about ordering one for my mini ITX build. However, it has been solid for a week. No smoke, no sparks. The voltages are stable. I am running an Intel I7-3770S on a Gigabyte ITX mainboard, with 8 GB of RAM and a PNY 250 GB SSD. I am using Linux Mint LMDE 6 for the OS. I like the modularity and the cable length was manageable. I can't predict long term reliability, but so far I am satisfied for the price I paid for this Apevia PSU.

The PSU measures 165.6mm long, but because it is modular, it fits perfectly in my JONSBO NV10 case, which specifically instructs to use PSUs no longer than 150mm. One seller on another platform selling a similar PSU told me that his PSU wouldn't fit my case, yet mine has been working flawlessly in that case. And I can't stress enough the benefit of using modular a PSU in a SFF build - you don't have to cram unnecessary, unwieldy cables in very limited space. For SFF PCs, fewer cables obstructing airflow means fewer overheating-related troubles in the future. The PSU has been stable and quiet powering a SFF build with AMD 9600X and Nvidia RTX 5060LP for more than two weeks already. I will come back to update the review if things change.
