1 out of 5 eggsPower Supply Died and company diapeared

This review is from: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

Pros: Looks good; Greate cables,

Cons: No longer works; not clear where the warranty service is.

Other Thoughts: I bought this power supply 12/2011. It came with a 5 years warranty. The power supply died a few months ago. Unfortunately, I do not seem to be able to replace it because the warranty site (www.ocztechnology.com/support/ticket.html) seems to no longer exist. In its place appears ocz.com, which no longer lists power supplies as one of their products..

Seeing that Newegg is still selling the product, I wonder who is now providing warranty service for this product.

5 out of 5 eggsAwesome power supply

This review is from: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

Pros: This is the best PSU I have owned. It has worked flawlessly for 2 years now. At one point it got wet while I was moving but after cleaning it with some Iso. alcohol and letting it dry out it still works great. The fully modular design makes cable management easy and all the cables are more than long enough even for a very large tower.

Cons: The fan in it is a bit on the loud side but nothing that should be worried about.

Other Thoughts: My build is an AMD FX 8150 on an ASUS Crosshair Formula V overclocked to 4.5GHZ. Two Radoen HD 7970 gpus in crossfire. Water cooled running 3 pumps and 7 fans. Im not sure how much power my machine is drawing but this PSU can handle it.

5 out of 5 eggs2 1/2 years and still running

This review is from: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

Pros: I bought this CPU for a new Intel build and I have not had a problem with it in this time. I would recommend it to anyone. At first I didn't want the modular unit, but it saved a bunch of space in my build.

Cons: No problems at all

4 out of 5 eggsGood Power Supply

This review is from: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

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: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

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 PSU

This review is from: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

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: FirePower ZX Series 850W 80Plus Gold Fully-Modular High Performance ATX PC Power Supply ZX850W, formerly PC Power & Cooling

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!!
