Review: The Teton (outdoor gear) of small form factor psu's - 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 socket Since 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.

Bought 2 and used for a year+ with no issues

### ⭐ Have had 2 of these, both failed early for no apparent reason.
*by C***N on January 31, 2026*

I had something like an Apevia 250W PSU for a project a while ago that I left sitting for about a year (off, unplugged) and when I turned it on it delivered *some* power but I found almost every pin on the 24 connector was reading 0V. I figured it was a fluke, and this one has good reviews, so I picked up this 400W to replace it. It worked for about a month until I unplugged it and moved my computer. When I plugged it back in, I saw some spark internally and it no longer turned on.
