4 out of 5 eggsWorks

Pros: *Shipped in Eggcellent packaging (see what I did there)

*Very quiet, no noticeable sound once installed.

*Works as it should.

*Has fairly long cables, long enough to fit most Slim PC's

*Cheap in prices.

*Came with power cable and screws (not always the case)

Cons: *Only comes with a 1 Year Warranty, that makes me question the reliability of the unit. (Though it was only $21.99)

*Smaller the the original TFX PSU that came out of my customer's Dell, leading to a gap where installed, and only 2 screw holes lining up. I saw several other comments about this in other reviews. Didn't think I'd have that problem, but I sure did.

Other Thoughts: All in all the unit works as advertised. Like I said, the mounting holes didn't quite match the Slimline Dell that it went into, but it still mounted securely and performed as it should. You get what you pay for here, hopefully the lack of warranty time make me regret the purchase, but hey, it's only a $22 PSU, so it's hard to complain about that.

There is a SeaSonic PSU of this type on here for around $40 or $50 that would recommend for long lasting reliability and wattage, but if you need a quick repair and don't want to spend a bunch on an old machine, this is your sweet ticket.

4 out of 5 eggsWell, It Works

Pros: It works so far, it's a cheap power supply so I'm not expecting much.

Cons: It's a TFX power supply but the mounting holes don't match up with the ones on the case and the main 20+4 connector is just 24 so I had to cut off the 4 because the board that I connected it to only has a 20 pin unlike other power supplies that offer the option to use 20 or 24.

Other Thoughts: Like I stated before, it's a cheap, cheap power supply and the machine it went into isn't anything great anyway. It had a FSP power supply and I have to say that all of the
mini-itx machines that I have built that came with that brand failed way too soon. I have used other Apex power supplies and they keep running strong so I do have high expectations for this power supplies longevity.

3 out of 5 eggsNot real reliable

Pros: Low cost

Cons: Too many deaths at a fairly young age
CHEAP fan chokes up and dies quickly

Other Thoughts: I have bought 4 Apex cases over the last 3 years that had this power supply in them. So far I've had to replace *3* of them, ONE while within warentee, the second one about 4 months out of warentee, and the most recent one at about 2 years old because the fan seized up and it overheated to death. The first two failed for no apparent reason.

The machines involved were a mix of AMDs, mostly 780G/785G chipset and one A10 - NONE of them use more than 110 Watts total power for the entire computer, which is a VERY low load on a 275W-rated power supply.

NOT very impressive reliability, even for a low-cost power supply.

Only up side is that they didn't take anything else with them when they died - plug in replacement PS and the machines were back up and running.

I will NOT be buying any more of these junk power supplies as replacements, and am considering changing cases due to APEX use of these in an otherwise nice case.

4 out of 5 eggsGreat replacement for SFF Foxconns

Pros: When the PSU in my Foxconn SFF Atom box went dead (which apparently isn't a rare occurrence), I searched high and low for an exact replacement. Finding none, I took measurements and found that this one is smaller than the OEM. A small case mod was required (enlarging one of the holes for the PSU screws on the back of the case) which took about 5 minutes with a small round file.

Cons: None so far

Other Thoughts: If you have one of the SFF (small form factor) Foxconn machines, get yourself one of these for when (not if) the PSU goes belly-up on you.

5 out of 5 eggsGood replacement

Pros: This is not a standard small form factor power house (they call it TFX?!), and seems only fit in certain cases need space.
I used 3 of this little guys replace my customers whose slim case power failed. It has been almost 3 years and customers have no complaint yet. I guess the power supply that I put in are kind of reliable, and that make me get my customers trust and confidence on me.

Cons: Again! This is not a standard size power supply, though it looks like what you need sometimes. Make sure meausre your old power unit and compare newegg dim. If they match, then you hit jackpot to save your old system

Other Thoughts: After 3 years from my last bought, I just get a call from a new customer who referred from my old customer. His small system power seems fail. He will bring in the system this week, and I am waiting to see if the power supply match this 275TFX. If it match again, then I believe I will have another loyal customer again! Thanks to newegg for bring in solution at the good cost!

1 out of 5 eggsBroke after 2 yrs of very light use

Pros: Smaller than TFX12V standard; fits in TFX cases where other TFX12V power supplies do not. Inexpensive.

Cons: Look at the listed MTBF (mean time before failure) - just 50,000 hrs, and I got nowhere near the mean. Other power supplies usually have MTBFs of >100,000 hrs. Very inefficient - only 65% efficient, while a good power supply is 80% efficient. Only 1 SATA connector.

Other Thoughts: You get what you pay for, and in this case, I apparently paid for the aggravation of having to buy another power supply. This PSU got very infrequent use until one day it just completely stopped working. I've replaced it with a higher-quality model.

4 out of 5 eggsWorked for a good while

Pros: This PSU is actually surprising. I've had it for over two years and it's retained stable voltages to this day. This was included in one of my Apex Micro ATX cases and it's powered 3-4 systems I've had in that case for the last two years.

Cons: Even though it's a stable PSU, the fan on it is cheap. Within a year it completely seized up after grinding for about a month. Because of how frequently I've opened up the case to swap out parts I've had the chance to keep the case dust free and so the bearings themselves are what failed, not dust buildup. It's not worth it for me to buy another, so I just cracked the outer casing open and mounted a third party 80mm fan on the outside of it using the same screw holes. It works again, but I don't have much space in the case it was designed for.

This PSU also only has a single SATA power cable, which is disappointing as usually DVD and HDD use SATA these days. Nothing an adapter didn't fix

Other Thoughts: This is a stable PSU. I've recently separated it from the case it was in and started using it for bench testing hardware before plugging them into a case and it still has stable voltages. I would buy this PSU again, but the case I was using this with just isn't worth another $30 to keep it floating.

5 out of 5 eggsKnow what you're getting before you buy it!

Pros: Fits the micro ATX case I'm using. Inexpensive.

Cons: Doesn't tell me it loves me.

Other Thoughts: We have 50+ micro ATX cases that use this power supply. They work just fine, cables fit just fine. Be sure you know what you're getting before you buy... this won't work in a standard ATX tower.

2 out of 5 eggsIncorrect Dimensions

Pros: I am sure that it would work fine...if...

Cons: The dimensions are incorrect in the product specifications. The PS is not 2.5" x 3.25" x length. It is smaller and did not match the screw holes in my case.
