For the moment i like this product and ive been using it for 1month no problem
This item is really good good quality good price worth it

Experience: 1 Months
Ive been using this item for a while and i got no problem so far
I have nothing to say this item i like it so much that I might buy another one. Its a good price and good quality

Blue LED's
LOOOUDDDEST thing in my system so far.
I think my video card is working up due to this powersupply. either not enough clean power, or something. It's also very loud.

Experience: 1 Days
 Verified Owner
Good efficiency for the price
Does what its meant to do
The fans are way to loud, it drowns out everything else in my case.
Only had this for a day, and I swear I'm not getting another OCZ PSU again. I got this cause my StealthXStream 700W was way too loud and annoyed me. Now this one turns out to be just as loud if not louder. I'm going to return this and get Corsair HX-750. I've had enough of noisy PSUs just cause its cheap.

Experience: 99 Days
 Verified Owner
lots of power, enough connection for SATA.
not modular power supply, not 80+
It's good power supply for a basic gamer. i have it on SLI with 2 gtx 260. i also used one gt 210 as a physic card. put 4 one TB hd and 1 1.5 TB hd. everything running smooth.

Experience: 2 Months
power handling
blue illumination
This psu can handle whatever you throw at it for a decent price! However, the fan's noise level is enough to drown out two hard drives, an aftermarket i7 cooler, a 4870x2 and five other fans.

Experience: 8 Months
Very well made, lots of connections. Nice and tidy.
Could have some more PCI-E connectors
This is a great value, this thing runs cool and doesn't make much noise. The build quality is evident in every place you look. The only improvement could be to add some more PCI-E x 6 and X8 connectors.

Experience: 2 Months
 Verified Owner
Steady power, price, performance
Has proved to be excellent value for money. A 850W PSU at a very good price were the main reasons why I bought this. Normally I would stay away from OCZ as they are losing some customer confidence due to increasing numbers of defective products but their PSU here has been excellent.

Experience: 2 Weeks
Lots of power and connectors. Handles everything I need.
Non-modular, doesn't have 4 PCI-e power connectors for SLI out of the box
Bought this PSU to power a quadcore system with GTX 260 SLI. It's capable of running 2 in SLI but probably not enough to do triple SLI. It isn't modular but I've used most cables. Only ones I haven't end up using is 1 string of SATA and 1 string of molex connectors.

No Power Flucuations, Lots of ouput
None so far
Great power supply can easily handle anything you throw at it. I have 2 8800 GT's and the power supply easily powers them.
