Review: Absolutely shocked - I bought this PSU to go in my new mid/high tier gaming rig and boy I have to tell you I was impressed from the get-go. It came in very solid packaging. All instructions and cables were neatly placed and zip-tied in the box. It even came with a cloth bag to keep spare cables (thank you modular design). One downside is the flimsy *dampening* rubber to be placed around the edges of teh system to cut down on vibration against the case. But, like most cases these days, mine came with little feet to aid in that to begin with, so it was a non-issue. So far *knock on wood* this puppy is one of the best buys I've made for the entire system.It runs quite literally as the name implies "silent." Case fans/GPU fans make up the bulk of noise (though they are quite quiet with their size/low RPM (200mm)). The thing is SOLID. Well made. I bought it on Sept 26th because, for whatever reason, it was marked down to 89.99. Most reviews prior complained this was mislabeled as a 1000W and I could see where that would be a bum deal if you truly need 1000W... but all I figured on needing was 850 and this popped up in the search list. You honestly cannot find a 1) modular, 2) 850W 3) 80 Plus (anything) for under $100... and now it shot up to $140... honestly I'm glad I jumped on this while the deal was hot and can only hope it lasts me as long as I feel it will. TL;DR version: The Pros: - Very quiet - Modular design - 850 W - 80 Plus Bronze - Came with nice bag to keep spare cables in - Price tag (the best part) $89.99 The Cons: - Rubber "feet" to be placed on the outer edges to decrease vibrations is a bit flimsy - It's not a "Corsair" ... but honestly I don't feel like dropping $130 for a 700W non-modular PSU....
Review: Its ok is quite accurate. - For most computers this power supply is perfectly fine. I use it in my main unit but do NOT try to run it at its rated capacity or even close to it. Half capacity it works fine but past that the voltage will sag and if your trying to overclock multiple video cards you won't be happy with sagging 12v rail. Half load it runs very solid.

### ⭐⭐⭐⭐⭐ Good PSU
*by R***E on September 9, 2013*

Honestly this PSU is great for anyone building a PC, however I think I got one with too many watts but oh well. Overall this is a very nice power supply and it runs silently in the background whilst powering all of your components. The cables that come with it are useful for daisy chaining up to 15 drives if your motherboard supports it and 4 GPU's. The main ATX power cables are neatly put together in a protective mesh so they don't clutter the machine and they are easily manipulated to keep them out of the way of other components. Overall I am very satisfied and would get another but maybe with a lower output for my current machine. REVIEW UPDATE: Ok so I have now had this PSU for 8 months and I and I can say it is relatively reliable and stable. It outputs all of the power my PC and I have plenty of headroom for upgrades. It's very quiet and it doesn't get hot and the fan is barely audible. I recently did a GPU upgrade from a GTX 650 to an AMD Radeon R9 270X and the card requires twice as much power than the 650 and the PSU still runs like a champ. I have had no random loss of power and everything has been stable.
