ITX-PFC400W Fully Modular ITX 400W Power Supply, Active PFC 90-264V | ITX Form Factor, Fully Modular, 80mm Auto Thermal Controlled Fan, Full Range Active PFC 90V-264V, Heavy Duty Protections

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.

I've had a few Apevia PSU's in the past in the budget sector, this one kind of falls into that sector when it comes to Mini-ITX power supplies. I would say that so far my biggest gripe on these Power supplies is the lack of a Power Switch on the PSU itself. Meaning that I have to unplug the PSU if I want it to not be powered. The power supplies have so far worked well on 24/7 workloads at around 30% load. The fans don't scream and the units don't get too hot. The fact that these are modular at this price point is really great. I would hope that they continue to provide these power supplies as I Plan to build more systems with these units.

Reviewing the 400w Apevia PSU on a 200w system: - Graphics card constantly turns off under full load. - When running hot, the fan will be barely active and then ramp to 100% for 10 seconds before returning to normal. This is very loud. - Trying to pull out the ATX cable is like pulling a molar. I have to hold down the motherboard to prevent excessive bending. - Not 80+ rated at all. I was sent another unit after the first was unusable. I have used the second unit for a year now. None of these issues are present on my other extremely budget 80+ rated power supply. Overall, this is a terrible product.

I have always wanted to use a modular in my builds to reduce clutter but most are very expensive. This one fits the bill very well.

Works excellent for a BC-250

Looks like a well made item. Modular design makes for easier installation.

You get what you pay for. Mine ran nice for a little while, but died after a move if you have more money, buy something else but if you don’t, this will probably do OK

I bought this for use with an AMD BC-250 mining blade repurposed. I couldn't find a pinout of the 14-pin ATX connector, so I manually traced the pins. See picture for pinout. Note: Several of the pins of the Apevia 14 pin connector go to more than one pin on the 24-Pin ATX cable. Connecting pin 14 to pin 8 through a switch should allow the PSU to be powered on and off.

到着予定日より早く届けてくださり ありがとうございます。 ファンの音が驚くほど小さくて、本当に動いているか不安になるぐらいで 驚きました。 とても、品質が良くて、5060RTXのモバイルGPU をeGPUとして運用することが出来ました。 持ち運べるGPUができあがりました。 一つ、感じた事は、うっすらと半導体が焼けた臭いがしたことです。 何日間か使用していて 薄れたので 最初の時だけかもしれません。

I used this in a media-centre PC and it's efficient and quiet. I did initially have a problem with one of the power cables but I contacted support and they sent me a new cable within 1 week.

It works perfect in my 1u server

Have been using for almost a year now without issue. Would recommend.
