A solid power supply, 3.5 stars
Pros; has some heft to it and feels pretty solid, lots of power for the price, runs quiet, long cables and lots of connectors, sleeved mobo and cpu power cables.Cons; none of the other cables are sleeved, not 80+ certified & it does appear to run warmer than other power supplies of comparable price range & wattage.Overall; this brand is fairly well regarded and the price was right for a +400w power supply, hence its selection. I haven't had any issues so far and system temps look fine, but, if i were to do this purchase over again, i might trade a few watts or a few dollars for a 80+ power supply from my usual brand(corsair). I haven't had this long enough to comment on reliability.

Quiet and effective. Good value.
Quiet and effective. Lots of power for a hungry video card. Lots of connectors makes it easy to connect to just about everything.

A bit of advice
I built my first 8 mhz computer in 1989 and bought my first enermax 10 years later. I'm a electronic tech and have built many power supplies for different circuit boards, so i know how they're done right. I recently purchased a corsair and i have no complaints...But the enermax brand is a step or several steps up.This model is so inexpensive for a simple reason, enermax doesn't build it, which happens a lot these days. I believe it's likely built by high power, known for its industrial power supplies. They did quite obviously design it however. I see all the little touches that point that out and when i tested it at my bench i found it provided very clean power beyond its rating. The unit is almost silent until you are working your machine more than about 40% and the extra cooling is needed but it's never noisy. The cables are plentiful and long, the two that power the board are sheathed in a flexible braid and there are so many connectors...Even molex and an old floppy connector. It's full of protection circuitry and the fan keeps running after shutdown long enough to empty the hot air from your machine. See what i mean about design?Let me point out something you can see, there will be four competitors just above that outletpc provides, all showing the fan side. Now look at this model noticing the circumference around the fan guard and how the metal was formed to the inside creating a venturi, take a look at the others. Superior design, not a big deal but many small ones put together are.So this is about as cheap as you can buy an elite brand power supply and if you know electronics you'll see the thought put into the entire design. Enermax designs and builds professional power supplies, $350 models, you can as well buy their 430w in another model for $100 but this one is not junk, it's good stuff for a budget builder or an excellent oem replacement. No offense intended to popular brands, i'm just guessing many of you don't know as much about enermax power supplies but they're popular in europe which is why it has a erp lot 6 rating. I can recommend this for up to a gtx 660 or the same in amd, but double check with an online power supply calculator because other devices draw power too. I hope i've helped you with your decision.

Works fine
I'm running an amd 4100 cpu and gtx 460 on this thing, and it hasn't had any problems so far at all. Nice and quiet.

Silent running
This power supply worked as i expected. It is not totally quiet but is very close to it.Now i only need a liquid cooler for the cpu to be completely happy.
