    I don't know what all the fire-starting stigma is about, this is a PSU and it looks nice and stays quiet.

    Powers my system without any problems. Runs quiet with eco mode on. Cables are a bit thick, wasn't an issue with my setup, but could be a problem for tight fitting case designs.

    Black cables are awesome. Fully-modular EVGA PSUs for $30-40 are awesome too. 10/10 would reccomend

    I've been told this PSU will go nuclear if you reach/exceed its wattage limit. Considering my build is a Mini ITX build, there's little need to worry. If I slapped a Ryzen 7 and RX 580 into this build, I'd still be roughly 140W shy of reaching its limit. Speaking of which, my RX 560 doesn't even bump total wattage beyond 220W. The RX 580 I just bought uses as much as 95W more. The Ryzen 5 2400G I'm waiting on is rated the same as the 2200G. Gotta love technological progress.

    Eco Mode is a neat little switch on the back that throttles power to the computer. It's a neat little thing to use if you're conscious about power consumption (i.e, running electronics on a surge protector near its threshold). Keep in mind it will throttle performance as well, so keep off if performance is a must. Otherwise, this unit supplies power without fuss. Its fan definitely keeps the unit cool, too. Eco Mode throttles the fan, too.

    Fully Modular with three 6-pin connectors (2 SATA, 1 peripheral), 1 VGA 6+2, 8-pin CPU, and 24-pin ATX MB connector is exactly what's needed for smaller builds. The SATA cables have splitters, there are molex cables and adapters, too. This is excellent for smaller cases that require meticulous cable management.

    It's a PSU. Modular and I've yet to fear it exploding.

    So far so good, fully modular which helps in a tiny build like this. it also has an 'eco' mode which shuts the fan off when not needed - i did leave this on in this build though to help pull the hot air out.

    * EDIT * I did try the Eco mode - off, it is amazing how much the exhaust helps this build, when the PSU fan was shut off idle temps were up around 45 degrees C

    This is a great PSU, my only complaint is I wish it had longer Sata Power cables, that can be solved by CableMod though.

    EVGA, Fully modular, cool temps, quiet, $50. The cables were super stiff, but also super durable. I was pretty harsh when bending them to the shape that I wanted them and they showed no sign of wear. The VGA cable having two 6+2 ends is stupid.

    works flawlessly so far, if anything happens I'll be sure to update this review.

    I know this is known to sometimes catch fire, but this PC doesn't come close to stressing this PSU out, so, it should be fine. Cables are nice and black.
