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

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.

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.

This thins will not provide any DC Voltage on any of its many MANY plugs. It arrived properly configured in 115VAC mode and was fed that. The AC pigtail is fine checked its getting AC fine. However, NO DC output.

Update #3: PSU died at just under 1 year of heavy/constant use. Warranty was great and I received a replacement. Put it to work in a chia mining rig to power 6 drives. Lasted about 6 months of 24x7 use. Warranty now states mining will void the warranty. At 30% duty cycle it might last a few years- heavy use less than 1.Update #2: I've now had this little PS for quite a while and it's been working great! In fact its been running 24x7 for the past 60 days drawing 250w in a small case running hot (75c) doing a little Ethereum mining ;-)Update: I've been using this PSU for a few months now. It no longer smells so whatever it was has burned off (luckily not burned up). It's been working great! My gaming rig is drawing close to 350W and it seems to be holding out just fine.I've been running this PSU in a smaller ITX gaming system for about a week now. I'm drawing 305W at the wall under full load so I'm running well under the rated specs. It seems to be working well however the smell of burning electronics is stinking up my house. I'm not sure if it's a capacitor burning up or some sort of dielectric grease used in the assembly process burning off. If the burning smell continues I'm going to have to return it which is a shame because A. It was a great value for an SFX PSU and B. 400w is plenty for most small ITX gaming systems.

The psu works well on a budget pc but produces a low level high pitch sound really annoying when it is off. Sign of low quality capacitors and coils etc. If you want a high quality mini build then this is not the option to power it.Updated to 5 stars: Psu broke on june 2020 probably due to poor quality components. I contacted Apevia and after some questions they quickly honored the warranty and sent me a version with better components. Customer service is mind blowing these guys are very professionals. Will continue to support them.

This 2 stars is for the false information not how well they work. The pictures & the info on the box shows an fdd connector and it does not have one.....

Works great, We had a power outage and my old unit never powered back on. This one was a perfect fit.

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.

Power supply is a powerhouse. Specifications are as marked. Quiet while running. Looks great. Nice and compact.

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!

Works well good form factor decent quality and value

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%.
