The new OCZ Z Series 850W (OCZ Z850M) breaks one of PC Power & Cooling’s tenets of good power supplies as it is a modular unit. As with the ModXStream PRO 700W this unit is provided by Sirtec (technically now Sirfa).

I bought this PSU thinking I was getting a top quality product only to find out that it is totally crap. My system kept on shutting down all the time. Checked the cables and everything was good except for the AC cable that came with it. It was never settled on the back, way to loose. So I looked for reviews and found out that this PSU has loose pins for the 24 ATX connector. I had to go out and buy a Corsair AX850 Gold+ and never had any issues. PC never shuts down on its own the way it did for months on end with this OCZ PSU. Currently have it RMAed and I will never buy OCZ again.I can never even sell the one they are going to send me because I don't want to sell junk to people. This will be put in electronic recycling when I get it.
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.
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
