Apevia ITX-PFC400W Mini ITX/Flex ATX / 1U 400W 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

This power supply works well, comes with nice breakout cables, and fits properly in a 1U ITX server chassis. I've been using it for several months with no issues so far.

Doesn't work from the start. Was out of return policy before I was able to install. It turns on but won't power off via PC without pulling the plug. It just power cycles the system back on after shutdown. Attempted to reach out to manufacturer but got no response. Buyer beware.

I really liked my 350-watt PSU (I have two of them in my backup NAS systems for RAID arrays running on the main NAS), but I think I overloaded one and burned it out. Technically, it still works, but it smells awful, so I contacted support. Their response was amazing—they sent me a new one right away. The support from this company is top-notch, and their products are affordable while performing their job well.Since I likely overloaded my 350-watt unit, I decided to upgrade to the 400-watt model to better handle my OpenMediaVault NAS server. My setup includes:- **CPU**: Intel i7-4770- **RAM**: 16GB- **Networking**: 10Gb SFP+ NIC- **Storage**: 8× 12TB HDDs + 2× 220GB SSDs- **Cooling**: Noctua fans for both the case and CPU- **Motherboard**: A random Shenzhen Machinist board for Intel 1150 socketSince switching to the 400-watt PSU, it has been flawless. It hit the ground running and has powered my system 24/7 without a single issue. I run RAID arrays, virtual machines, and containers, and it's always connected to a UPS.I highly recommend this company and their products—I’d consider them the **Teton** of small-form-factor PSUs. Apevia did a great job with this product, and their support is outstanding. I especially love the **modular design**, which keeps my NAS’s internal cabling much cleaner.The PSU fan is **quiet**—I don’t even hear it. My Noctua fans (2× 80mm for the case and 1× 90mm for the CPU) are louder. Honestly, I wouldn’t bother replacing the PSU fan despite what some content creators suggest—the gains are almost nonexistent.If you’re considering this PSU, **go for it!** It’s an excellent value, and the company stands behind their products.

Works great and has connectors for a non gaming desktopDoesn't have enough power to run a midsized graphics card like a 1650 or better, more like a 1050 2gb type of card or lower or integrated graphics

Excellent power supply. Very well made. I am using it as a supply for a drive rack and it works like a champ. Would make a great supply for a bench supply also.

Pros-Quiet-Decent modular connectivity-Cheap-Cable lengthCons-Not 80 plus certified-Tight fit in small ITX cases-Can't handle really low loads-CheapBought this to power a Minisforum BD795i SE and live inside a 3.8L case. The size complaint would be my use case, however this unit kept resetting on me because that motherboard setup uses maybe 1 watt at idle. Ended up going with a higher tier brand PSU that is 80+ Gold certified...Tested it out on a 11400+2060 setup and it pushed 300 watts no problems. Fan is pretty quiet close to full load too. I'll keep this PSU around for "test" purposes, but you get what you pay for.

Super compact. Fits perfectly in a dell optiplex 7050 sff. Included tons of cords, follow the directions when hooking it up. The PSU fan is very very quiet even under load.A separate 24pin to 6pin dell power adapted was needed to power up the 7050 motherboard.Highly recommend.

It started sparking and smoking when powered on. I immediately turned it off and packaged it for return after it stopped smoking. It didn't damage my motherboard thank goodness.
