Review Date: 11/24/12
Cons: -The fan continues to spin for around a minute after shutting down.-Not FULLY modular

Pros: -Great power efficiency (80+ gold)-Affordable-Lots of extra cables-Quiet fan
Comment:
Note that this is not FULLY modular (look at second picture).Bought this on sale for 60$ after MIR. Definitely a bargain for a power supply of this caliber. Since my setup is minimal, I only needed to use 1 of the modular cables (for GPU) since my setup is very minimal. My old system went down after the 4-pin connector burned its socket on my motherboard since I purchased a cheap no-name PSU that didnt deliver clean power. Don't make the same mistake as me.

Cons: Not enough 6-pins for me, fan blows into the case rather than out of it but I'm not using a case

Pros: Good PSU, clean power, no problems
Comment:
Good 850w PSU. I've run it for 30 days mining bitcoin with 3x 7950s and my Kill-a-watt reads about 675w, so I assume it's pulling 625-ish on the 12v rail. Haven't had a problem yet.

Cons: Ugly cables, short cables, fan spins long after power off

Pros: Great price, quiet, great energy efficiency
Comment:
Great item, was a great price point also. However these cables are really short and a struggle to get to plug in. Additionally the psu fan spins long after power off, I noticed it was spinning when I turned off my pc, went to sleep, woke up and its still spinning. Need to hit the switch on the back to kill the power and prevent the psu fan from spinning. Weird. None the less a great price at 69.99 you cant ask for more

Comment:
I didn't realize how noisy my old OCZ PSU was, this new one is so much more quiet. Even though it has modular cables I would have liked some shorter ones.

Full modular and gold certified PSU. With 850W you can sustain a high end PC and expect to keep your power up to 5-7 years. I just have one GC (Radeon 7950), but I overclocked my i7 3770K at 4Ghz and all is doing well!

Comment:
I bought this PSU in sale for 99$ and it defenitly worth the price. Its probably the best choice for an high-end overclocked system. I've been since 6 months with two GTX580 videos cards and it works VERY well.

Cons: Idle mode doesn't allow USB ports to charge devices while the system is off. I didn't use all of the non-modular cables, so I still have one that is just hanging loose. Not fully modular.

Pros: Modular cables are good for small form factor systems where space is at a premium. Cables are good quality and have looming on them. Cables are long enough for full tower systems. All connector types included for different motherboards and graphics card. Fan is nearly silent. Low power idle mode when the system is off. Really thick 120V cable.
Comment:
I bought this power supply to be future-proof for when I buy new video cards. I currently have two AMD HD6870s in crossfire and it seems I have plenty of power to spare. I built a small form factor system inside of the Thermaltake Armor A30 case, and I found the PCI-E power cables to be too long, so I bought the Silverstone PP05 cable kit to get shorter ones. The price for this power supply is great, given that it's a gold certified version.

Comment:
Wish the power supply was black so it would match my case.Not a big fan of the gold color pci-e connectors.Fan still runs for a few minutes after shutting down to cool itself.People still don't think OCZ power supplies are reliable(I'm still not convinced until more time passes) but I hear the customer support is very good.

Pros: - 80+ gold- shiny brushed metal casing- quiet but capably 135mm fan- 5 year warranty (they replace your unit, not repair it...so NO WAITING TIME)
Comment:
WORKS PERFECTLY!!! The only bad thing about it is that it has UGLY cables! Yuck! I had to purchase extension cables just for it to look great. Otherwise, this is a great product and I highly recommend getting it especially now that it is on sale.

On my old Antec Earthwatts, which is 80+ Bronze, I was pulling 450 watts during prime95 + furmark. With the new PSU, which is 80+ Gold, I pull 360 watts during the same tests. More efficient? Yep. Get this now while it's on sale!!!

Cons: Not meant for bottom mounting

Pros: Modularworks well
Comment:
I bought this one on sale, wanting a good PSU for years to come and to be able to SLI. I have no complaints on it, works well and looks great (except the yellow connectors). The only thing is that when bottom mounting it the cables are short and you can have problems with the sata power ones but it's not a big deal. I recommend this PSU.

No complaints about this beast YET. I often hear alot of things about OCZ power supplies being unreliable over time, but I got this for 89.99 after MIR on sale, and being 850W and modular, it looks great in my case and gives me room to upgrade to SLI later on.Right now its holding up my i5 2500k, gtx 570, and WD Black sata 3 hdd.

Cons: A little lacking in variety of modular cable options.

Pros: Nicely braided cables with plenty of flex and decent length.Quiet.
Comment:
Bought on sale at a great price after rebate for an 850w PSU. Replaced an older 620w corsair modular psu and immediately found the OCZ to be much quieter and to have much beefier modular cables that still give enough flex to route decently in a fairly cramped case. The selection of non-modular cables pre-attached is fairly logical, but in a bottom mounted case the fact that they emerge from the front corner (with fan facing up) added just enough distance from where they come out to my cable routing holes that i had to use an extension cable for the cpu power to get it routed cleanly. Also, the orientation of the power connectors chained together on a single cable (ie. 3x sata, 3x molex, etc) seem better suited to a psu mounted at top of case as far as how the connectors are laid out to plug into standard mounted HDDS and optical drives. 80+ gold rating is a great added value as far as power efficiency - a great buy at the right price. Powering an OC'ed 4ghz i7 with 4hdds and a gtx 275 vidcard.

I put this power supply into an Asus case so that I could upgrade the video card to a nVidia GTX 280. The upgrade was easy even though the power supply was slightly larger than the original. The fact that I could choose what power cables to add was a nice surprise. I didn't end up with a mass of unnecessary cables in the case that I had to find space for. The power supply has been in for a few weeks now and I have had no issues.
