4 out of 5 eggsGood Power Supply

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: Modular power hookups are freaking amazing. It makes cable management a breeze.

Easily handles a mid-high performance machine

Doesn't have any heating issues

Cons: The fan is a little loud, but I wear headphones so it doesn't matter much. The only time there is a problem is when I'm trying to record with my studio mic and it pics up the fan if I'm too close to the machine, but that's why you're supposed to be in a separate room anyways.

3 out of 5 eggsBOOM!

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: Ran very well for a little over a year.

Cons: It exploded with a loud boom, (Like a .38 caliber
pistol shot next to me) and went dead. Provided quite an adrenaline rush as I thought it WAS a gunshot. Did not damage computer otherwise as far as I can tell.

Other Thoughts: OCZ was easy to deal with and just shipped me a new unit so we'll see how that works.

5 out of 5 eggsGreat deal

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: Couldn't be happier with my psu. Got it for a deal on top of it having gold certification. you want something like this if your paying the electric bill. love the modular and well constructed cables. SUPER quiet.

Cons: Truly has none.

5 out of 5 eggsGreat PSU

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: Fully modular. Purchased it while it was on sale. I invested many hours researching several brands, models, wattage's etc..and I am very pleased with what I choose. Cables came in a nice velco bag to consolidate left over cables. All cables came wrapped in black braided mesh and heat shrunk on ends, and plenty of cables for future expansion or light mods. The fan is very quiet and removes heat well. I have 2 blue cathode tubes & 2 blue LED spotlights, and still have plenty of ports on PSU left. This is a bit on the pricey side, but with the gold rating and quality build, I will not have to worry about it shorting out any of my other expensive components. Overall, this PSU is worth the money, and I am very happy with my purchase.

Cons: It would be nice to have a LED fan. But not worth less than a perfect rating.

5 out of 5 eggsSolid Power Supply!!

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: It;s lasted me over a year now and it hasn't given me any problems! I've been running a 560 ti, a sandy bridge i7 (stock clocks) two 3.5" HDD's, a asus z68 mother board with 8 GB of corsair ram without a glitch! The fan is dead quiet, I've never heard it the whole time I've owned the system!

Cons: The stock cables with a little short for a coolermaster haf 932 case but then again this case is freaking huge so no eggs deducted :P

Other Thoughts: A very nice power supply, you won't be disappointed!!

2 out of 5 eggswanted to give good rating but...

This review is from: OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Haswell Core i3/i5/i7 Intel 4th Gen CPU Haswell and AMD Phenom

Pros: -fully modular
-price. I got it on sale and rebate.
-pretty stickers on the unit.
- very quiet under half the load.
-boat load of cables

Cons: 2 months of ownership and it died on me.
-cables are a bit stiff
-different wire colors at the ends of cables are visible
-pcie cable connectors at PSU is white color.

Other Thoughts: This morning I pressed the power button on my pc and nothing happened except the motherboard led light was on. I went to work and when I came back I reinstalled my old PSU which was replaced with this OCZ PSU and my PC booted it right up with no problem. I had resolved a previous rebate issue with OCZ and I really wanted to give it a good egg rating but at this time, I cannot give this more than 2 eggs perhaps If RMA process goes well, I would add more eggs to the future rating.
