5 out of 5 eggs2 years - works as expected

Pros: reliable
low cost

Cons: none

Other Thoughts: Paid $40 for this, 2 years ago - no problems.
The only minor issue (and I admit that it's one of personal preference), is how they've set the bottom fan speed limit.
My system draws less than 100 watts from the 120 volt AC.
It's efficient (I don't do gaming), and I've set the motherboard to high efficiency mode.
While I admit that the fan is very quiet, the amount of heat flowing out of the PS is also very low.
So I would have appreciated an even "lower" bottom limit to the fan speed, so that in cases like mine, the PS is essentially inaudible.
Lower fan speed generally equates to longer fan life, before the bearings start to increase their noise, caused by wear.
But these sort of manufacturing tradeoffs are what we encounter all of the time.
So after two years, I would call this a wise purchase.

3 out of 5 eggsNewegg Brix Bundle

Pros: Don't really know what to think. Some tech genius decided to bundle an mSata drive with the Brix which only supports M.2 SSD. With this marketing prowess, it is difficult to understand why I look to Newegg for anything!

Cons: It is not the products fault, but I can't recommend anything I can't actually use.

5 out of 5 eggs2 years of 24/7 operation and still going strong

Pros: It's like my Toyota Camry, it just runs and never gives me any problems

Cons: None

Other Thoughts: I wrote my original review of this power supply on 3/23/14. It's been running my FreeNAS box for 24/7/365 for 2 years with out a hiccup. So the longevity is there. Great for a low power build.

5 out of 5 eggsGreat Product!

Pros: -voltages are steady and proper
-stays cool
-lives up to 450w rating

Cons: -the 4/8 pin CPU power connector wires could be 6-8 inches longer to please those interested in tidy cable management. Grrrrrrr

Other Thoughts: Rock steady as expected from Antec psu's, will be buying more and recommending to others. My new "go to" psu

3 out of 5 eggsAntec VP450 Power Supply

Pros: No issues so far, good fit, quiet fan, does what it should.

Keep in mind it has a 6-pin pcie connector, not 8. Be mindful on what you plan on using for graphic cards if you dont want to have to use adaptors

Cons: Rebate program is a joke, don't count on it as your purchase deciding factor.

Other Thoughts: Still a good purchase for a micro ATX build, even without the rebate

4 out of 5 eggs

Pros: The power supply in the old (325 Celeron) minitower that I replaced a refurbished computer with, would not work with the Gigabyte 78LMT-USB3 I purchased from Newegg. This power supply was purchased to fit that need. Computer seldom gets turned off, and everything works fine.

Cons: None.

Other Thoughts: Review late due to move.

4 out of 5 eggsA solid PSU

Pros: Great PSU for the sale price I got it on. Solid performance and not too loud.

Cons: I wouldn't pay the $50 full price for this.

Other Thoughts: A few reviews complained about the top exhaust. Not sure what cases they had an issue with but I've used it in both top and bottom mounted cases without any problems whatsoever.
