TFX-PFC500W TFX 500W Power Supply, Full Range Active PFC | TFX Form Factor, 80mm Auto Thermal Controlled Fan, Full Range Active PFC 90V-264V, Heavy Duty Protections, Quiet Operation

Apevia TFX-PFC500W TFX 500W fits perfectly in a Lenovo ThinkCentre M72e small SFF desktop case using existing OEM motherboard (Xeon CPU installed) running a RTX 5050 video card. It doesn't have an official efficiency rating, but it boots up. The only 500watt tfx psu I could find for a good price. Giving 5 stars until i come across any issues.

I upgraded my Lenovo Intel i3 8100 90HV001MUS tower with an AMD Radeon w5500 card and knew going into it the OEM power supply would need to be upgraded. This is what I had to do to get this PSU to fit and function. You will need a ATX 24 pin to 10 pin adapter for the main connector. The two 4 pin to SATA power cables that are currently attached to the main board can be eliminated unless you plan to use the laptop style DVD-RW drive. If you do retain that cable. Only one of the 4 pin CPU cables from the new PSU will be used, and only 1 of them fits. It’s just barely long enough to snake under my GPU card and over to the CPU power point. Consider ordering short extension cable when you order the 24 to 10 pin adapter. I considered cutting and splicing to make it longer, I might still do that. For right now it works the way it is. You will need a 180 degree 6 pin GPU redirect adapter if you use the same card I did. There isn’t enough clearance to close the case and plug in the GPU power cable. The plastic mounting tray for the wireless card and NVME HDD interferes with the new PSU, its longer than the old PSU. If you have the M.2 sockets populated with a wireless card and NVME HDD you will need to 3D print (or figure out another solution) stand offs to use those cards. I found an STL file that works on Makerworld.com by a user named Cloverbio. Be prepared to get creative routing cables. There will be a lot of extra you won’t need. If it becomes an issue in the future I plan on opening the PSU up and desoldering cables I don’t need. If you can find a TFX PSU that has a modular cable system it would make your life easier in the long run.

Nice small PSU that fits into MOST builds. Find a bracket to work with it is a little difficult. If you don't mind modifying it, it can work well for you.

Lasted about 2 days... Luckily I was next to it so when it popped i was able to unplug while it was starting to catch fire. Do not recommend unless your system needs 250 Watts at most then maybe. I was pulling slightly more than that.

Worked great for my optiplex 7040 mini tower had to modify the case a bit for it to mount up but it works

I have been using Apevia Power Supplies for about 3 years. 300W, 400W & 500W units. They make a nice upgrade or replacement for the oem units that come with the InWin cases that I primarily use. I use the 400W & 500W when I install a multi display video card (usually nvidia K1200). Up until recently I have not had any issues with any of the power supplies from Apevia. And so far only 1 of about 30 units I have installed has failed and that I think was due to the user bypassing the UPS unit. . That said, the last two Apevia TFX-PFC500W TFX 500W units were both bad. They worked fine, but once I stood the case up on its side both of the units starts ticking like the fan was hitting something or was not mounted properly. (all the PCs are stood up this way). If I turned it upside down or on either side the ticking stopped. . They replaced one with another unit and it did the same (thus 2 units). So then I ordered a 400W and installed it. No problem with it, no ticking. This tells me that they must have gotten a bad batch. I will try again the next time I need to get one and hope we have gotten past the bad ones. . I gave a 4 star only because getting two in a row means bad quality control, but all the previous units were fine. Otherwise I would have given them a 5 star. And I will not knock them down more unless a month from now I am still getting ticking units.

worked perfect although it was a little larger than the one i replaced had to leave top open on computer but that was ok

I bought this Apevia 500W TFX power supply as a replacement for a failing unit, and while it powers my system without issues, it runs way too hot. Performance-wise, it does what it’s supposed to—my PC stays stable, and I haven’t noticed any voltage drops or crashes. However, after running for a while, the PSU casing gets so hot that it’s uncomfortable to touch for more than a second. The built-in fan doesn’t seem to move enough air to keep it cool, which makes me worried about long-term durability. If you have good airflow in your case, it might be fine, but in a compact setup, expect it to get very warm. If you plan on pushing it close to its rated wattage, I’d be cautious. ✅ Pros: Works reliably, no power issues Fits well in TFX cases Affordable for a 500W unit ❌ Cons: Gets extremely hot to the touch Fan doesn’t seem strong enough for proper cooling Might not last long under heavy loads Would I buy it again? Only if I had no other choice—and I’d add extra cooling.
