APEVIA SFX-AP400W Mini ITX Solution / Micro ATX / SFX 400W Power Supply

Spent 3 weeks looking for a small form factor power supply unit replacement for an old desktop repair. Old HP Pavillion computer uses a microATX form factor. Depth into the computer chamber has to be less than 4" to fit the cabling to the internal motherboard and hardware. Very, very difficult to locate a microATX for factor. I wanted a price in the $20--25 price range. The Apevia came in high wattage. It has a power switch for on/off, and this is important. It was priced at $30. The quality is good. It looks very nice--comes in all black profile with black covered cables, so sleek and modern. Small size so fits where there is space limits. You will need to buy a adapter plate SFX to ATX. The computer is running, surfing the internet, typing in the review. If I had a similar repair to do, I would buy it again. With a discount code, this is a dope buy. 1 4 4

So far it is working great. It is much quieter than my last power supply but not as quiet as I had hoped but still so much better. Update 9/10/2019 - The power supply is still working but now the fan is going out. It is making some very bad noises. Just a few months past warranty so I will probably have to replace the fan myself. I guess you get what you pay for. At least it is still working and as for problems, it is a fairly easy fix. Not going to knock a star off since it did last over a year and is technically still working as is, I just don't trust the fan anymore.

This product came just as advertised, having a 6 pin connector for a GPU and 8 pins for my CPU power. However, right when I plugged it into my wall outlet and flipped the switch on it, I got the worst coil whine. This is before I even pressed the power button on the computer, so it was under no load. Once it is under load, however, it works fine and the whine goes away. If I put my computer to sleep or shut it off, it starts back up again. Not acceptable considering my computer is in my bedroom and I can't even hear myself think when it's shrieking the way it does.

This is the third one of these PSUs I've bought. This one is for an ITX case I bought a while back and wanted to update. Another one is in this silly old Dell by my foot -- it's not the right size, but I was able to secure it and it's working. Not sure where I put the third one. Anyway, for a small power supply they work very nicely, They make plenty of power (at least for any Video Cards you'd be squeezing into a case that needed on of these) Plenty of connectors (almost too many) and nice and quiet. The only way to improve it would be to make at least some of the cables modular - but that would raise the price, and the price is one of the nicest things about this little PSU. Found the other one - it's in a Thermaltake ITX case that could be using a normal sized PSU, so there you go.

I purchased this for a low/mid range system going in a SFF case and needed a cheap SFX supply. The first one I ordered had horrible coil whine when powered off (5V standby), so it was extremely noticeable. Decided to reach out to support (Amazon was sold out so couldn't replace). They were extremely responsive and after I sent them some info (serial and copy of invoice), quickly dispatched a new one. Got it 4 days later and it's works great powering my i7 4790k and GTX1070 mini without issue. Fan is a bit louder than I'd like, but that's to be expected for a supply that only goes for $30. It's not horrible. All in all, I was a little disappointed at first with the quality, but their support seems top notch and ultimately got what I needed and quite happy with purchase.

Wish I'd paid more attention to the negative reviews. Supply lasted a little more than a year, with no problems, when suddenly I noticed that the fan noise was louder than it had been. Didn't pay much attention to it, when a few days later it died (I could smell that something had shorted/popped). Not good, so now I'm looking for a replacement. I won't buy this brand again.

I've seen a lot of bad reviews on this brand power supply. For what it's worth maybe I just got lucky. I've had zero issues. The power is solid and is supporting my NAS which runs 24/7. It's been up for several weeks now without a glitch. i do have it on a UPS so maybe that stability helps. In any case for the money I am a happy customer.

The first one i recieved I am deeming it DOA because it had a short in one of the wires. I had to flex the wires to test power supply. I had to refund the first one and order another. The wires seems really stiff which I think why it failed or developed a short. Little to no quality control. Packaging is really tight for the application. Otherwise the power supply work I would recommended for budget builds or replacement for store bought pcs. EDIT: the second unit I received was in the same condition. I think that a failsafe was being tripped inside the PSU. (Out of 3 PSUs this one exhibited this symptom) It seemed the happen with every power cycle from the I/O switch or unplugged. I had to remove the +4 pin from the 24pin connector and reinstall it just to get the motherboard to power on) from there it was fine worked like normal. I had a couple of issues related to game crashes and a bsod but I have to run a couple more tests that confirm that it's the power supply.

Nice under no gpu load but it burn out during load test for total load 200W (i7 6th gen + itx 1050ti) Rated power is not real.

I used the APEVIA SFX-AP400W power supply to upgrade my Dell OptiPlex 5050, which is an office PC. It fits perfectly in the small form factor case and provides enough power for the system's needs. The installation was straightforward, and the unit is compact yet feels solid. It runs quietly, which is a big plus since this PC is mainly used for work purposes. Despite being an affordable power supply, it has been reliable, and I haven’t experienced any issues with stability or overheating. Overall, if you're looking for a budget-friendly, efficient power supply for a compact PC like the Dell OptiPlex 5050, this one does the job well!

No complaints. Great size for an ITX system. Runs well with an old 6th gen PC for general computing.

It worked perfectly for just under 2 years, when it failed overnight. I was using it on a server with 60W average power draw, with peaks of up to 120W. It died during a backup, at one of these power peaks. When it died, it started power cycling about once a second, destroying my boot SSD on the server. Would not recommend for reliability. Efficiency was not good either, as when I switched to a Gold rated power supply from a reputable manufacturer, power draw decreased about 15%.

Works well good form factor decent quality and value
