Apevia SFX-AP500W Mini ITX Solution/Micro ATX/SFX 500W Power Supply

Good replacement. The PSU in my NAS was on having technical difficulties and needed to be changed. Works really well and I am really happy with the results.

The fan started making loud, grinding noise after 18 months. It was exceptionally easy to replace with a same-size computer fan (80mmx15mm), and this PSU is still the best SFX value around even after that.

the first one I received had a fault somewhere that made it only output around 9v on the 12v rail so tbe system wouldn't post, I tried with a difrent non sfx supply and everything worked fine, I also tried this psu on a difrent system and still low voltage and no post, so I put in for a replacement because this was the only psu in this formfactor avalible in this price range so it was that simple, could I have shelled out for a stupidly expensive gold sfx from Silverstone or seasonic or corsair or cooler master, yes, did I want to literly put as much into tbe psu of this little usff server build as the rest of the build costs or close to it... absolutely not, so I put in for a replacement and Amazon being Amazon was absolutely on it and had me a replacement at my doorstep with 3days and the new one works fine, it's not the best and the little fan that could realy works up a sweet trying to tame a ~300watt load but hay I didn't expect much for less than $40 and it's stable, it passes a aggressively unfair stress test with no perceptible voltage drop on any rail, and when I'm not taking it to a blacksite torture chamber and just using it under regular loads it absolutely stands on it own feet, damn site better than the pico psu it replaced...to be fair that pico was rated for 300w and I'm pushing a 5600 with a slight OC and a rtx 4060 LP but in reality that should be more than around 200watts so idk it just struggled to deliver a stable voltage even while being pushed via 12v off a 1200watt hp ProLiant Via a mining breakout that is more than capable of delivering the requisite currents for almost a dozen other devices using either 12v like switches and routers and a firewall and a couple asrock deskminis via a beefy marine 12v to 19v boost converter, idk I guess the inductors on the pico were cheap or maybe the guage of wire from the 12v supply was to thin idk it probebly should have only been rated for a buck fity but hay in no matter now cuz this unjustifiably cheap sfx psu has replaiced it and now I can reliably power a array of 8 3.5in hdds in this server finaly lol...no this is not long term cold storage that I'm fooling myself with being acceptably safe with this ultra cheap psu no this a 8 fairly fast big enterprise HDDs in a complicated and admittedly conveluted lvm array with nvme pcie 4.0 caching that I can read and write to ad a clip capable of fully saturating a 10gb full duplex link... and for that purpose this little budget server that could...realy realy can lol

This power supply was cheap enough and I was hoping it would make it longer than 30 days. Just 30 days after the date of purchase and installation the bearing in the fan started leaking which caused an internal short with shorted out the unit. After replacing the unit with another from the manufacturer under the one year warranty, the second unit kept powering down my computer for unknown reasons. Upon further investigation I found a power wire had pulled out of the sata connector for the hard drive which was causing blue screens and shutting down the computer improperly. Save yourself the time and buy a power supply from a known manufacturer with a good warranty. This is not the unit that I would recommend to anybody.

Works great - not as noisy as other reviewers say (of course that can be just reviews getting aggregated) but worked perfectly. FYI - no 6-pin for higher end video cards - had to get an adapter to get the extra power - of course if you're building a higher end system the power capability might not give you what you need here -- but the price is right and the quality is as expected.

Needed this for a super budget SFF itx am4 3600 build with 3200mhz ddr4 and a old 3060ti. Something small, portable and can game. I know there's a mathematical way to predict how many watts you need. 500w seemed slim to me for what it was going to power. I took a chance on this. For only $36 I wasn't really expecting this to pull through. To my surprise no problems at all. Have gamed on this PC for hours no issue at all. Don't expect miracles if you have high performance parts, but if its a low power pc build this should do the trick, fantastic price as well.👌👍

I bought this Apevia SFX-AP500W power supply to replace a 250-Watt power supply that came with one of my Mini-ITX cases. My original 250-watt power supply was not sufficient to handle USB 3.0 devices I plugged in, so I needed a more powerful one. I tested the power supply before installing it and all voltages were shown as within tolerance except for the 5VSB. The power supply tester showed the 5VSB was 5.3 volts. I used a digital multimeter to further test the output on a specific pin on the 24-pin connector (for the 5VSB). It read 5.21 volts which was near but not over the +5% upper tolerance of 5.25 volts, so I installed the power supply. I had concerns about the fan due to what others have posted. The fan is quiet, as is a previous purchase of this same power supply I bought for another machine back in May of last year, so hopefully they will stay that way. The power supply appears to be well made, at least from outside appearance. I gave this power supply an overall rating 3 out of 5 for two reasons. One was the 5VSB voltage being very near out of tolerance, and the other was due to an apparent lack of warranty. Amazon shows the power supply can be returned within 30 days, but refers you to the manufacturer's web page regarding the warranty. I went to the manufacturer's web site and looked up this power supply and found a tech support number but no information about a warranty, nor did the specifications card that came in the box mention a warranty. I did not call the tech support number to find out, so I can't really state it has no warranty, but if this is important to you, you may want to find out. I consider this power supply to be suitable for an inexpensive, somewhat low power system build, but after looking at some of the other reviews, would be leery of installing it in a high-end build.

I got this to upgrade my dell optiplex and it is perfect would definable recommend that you buy it if you are looking to upgrade your dell optiplex.
