One of Tom's Hardware's top tier PSUs. I got it for below $100, which is very worth it. Cords were ample and are very high quality.

love that I got this at such a great deal! I pulled the trigger on this thinking it wasn't going to go down any further in price, and I was right! It was back up to $190 when I last looked at it.

I wanted something somewhat future proof, just in case I would get a more powerful GPU or maybe SLI in the future, the RMx series is new, good, well built, with a better price that other series that have the digital link system that I would really never use.

Works well. Was impossible to find a set of custom sleeved cables here unfortunately. So I made due with extenders which did make cable management much harder.

Solid PSU, the modular cables makes cabling less of a clusterf***k. Very quiet.

So far no troubles, I like that it's Fully-Modular so only the cables I need are in the case!

A bit overkill but it was the same price for a 750 watt, so I was just like... whatever. Great modular PSU. I trust Corsair in this regard. The only place it loses its star is in the wall adapter. When I was building, it just didn't feel like it was plugging into the pc securely. In fact it was a bit loose. After I was done building and put the PC where it actually lived, I had do make sure the cable was tightly curved so it wouldn't wiggle in the socket. This same thing happened with a work PC in my office. We ended up switching a to a different cable to plug it into the wall that was much more secure and a tighter fit. I may call Corsair and ask if they have a solution to this... The computer is getting power though. It works.

It's a power supply that works. Flat black cables, and fully modular interface. Not much else to say here.

PSU: I found it on amazon on sale. Never looked back. It came in a felt bag! Everything about it really feels high quality.

I used this for my first ever build, and by far - this was the most challenging part to choose without and true hardware knowledge. After a massive research this was my No.1 pick, it has excellent efficiency, Corsair PSUs are known to be highly reliable and stable. I am not an electrician or hardware expert so I can't completely rationalize my argument, but anywhere I've looked - this averages as the best option for my build.
