Disclaimer: I haven't had this for long.

The build is very sturdy. The modular design is fantastic, though that has made cable management a bit tricky. However, I have no experience with other PSUs, so this may certainly be an upgrade from semi or non-modular PSUs. What particularly appealed is the 80+ Gold rating, which means I can use my computer at ease without worrying too much about inefficient power usage or some freak accident that would kill all my other components.

I wanted the 650w version, but I refuse to order from NCIX anymore and Memory Express was sold out, so only amazon had them for Around $150. Settled for the 550w, fully modular is super nice, way better than my non modular XFX.

Seems like a badass PSU to me but it's my first one. It's tier 2 fully modular gold rated 550w. Got it so I don't have to get a better PSU when I upgrade my CPU and GPU. 64$ through newegg after rebate

Because of my case I needed a modular power supply that did enough to keep me going. The EVGA 550W GS was more than enough for all the components and it even has a Eco Button to help with power consumption. I like the feel of it and it is actually the quietest piece in my build. Have cables for one more GPU for the future! Pro: Eco button help with minimizing fan power consumption. Gold certified Con: Main power switch isnt labeled On/Off. Thought I had a dead mobo but turns out I didnt even turn it on.

Gold rated, and has all black cables. No colorful ugly cables. Awesome PSU.

I was surprised to see this came with a jumper tool so I didn't have to go find a paper clip. This was recommended to me buy a staff member at microcenter, no issues yet. Only using it until I can get my psu out of my previous PC.

I love EVGA's customer support line. I was missing some SATA cables from the box and they overnighted them to me. They do wonders for me.

Amazing modular power supply.

Had I done more research, I might have gone with the 550 G2. Nevertheless, it's a good power supply. It's very quiet, and powers all of my components just fine. It should last me for a while, but it'll keep me from ever using an R9 390.

Power Supply - The selected power supply has been tried and remains true. I have had steady, consistent power coming from the unit. It is quiet, and does not run too hot. The modular nature allows for lots of flexibility in cable management. Excellent Quality from EVGA. Between this piece, and the graphics card, I have found my first trusted PC part manufacturer.
