On OCZ

post #1 of 11
Thread Starter 
OCZ is a brand that pops up a lot, and gets a confusing mix of good and bad rep. Some people report them working well for them; others report early failure and poor performance. They've been around for a while, and are a major supplier of RAM and SSDs.

OCZ's main line-up is the popular "XStream" lineup. These include StealthXStream, ModXStream, and GameXStream, and also the "Fatal1ty" branded units which are rebrands of ModXStream with red fans. These power supplies are all made by FSP, based on their Epsilon platform. They are average-performing units with good ripple suppression but mediocre voltage regulation (opposite of the CWT PSH platform). They are fairly reliable, but capacitor choice is sketch, and some are overrated. I will not cover every model, because there are too many and I don't have the patience for that crap. Basically, they're "good enough", but as enthusiasts I don't think we should settle for "good enough", especially as the mediocre voltage regulation can have an impact on overclocking potential (bad voltage stability can affect core voltage values; as opposed to ripple, which affects core stability and VRM reliability). If you're on a tight budget they'll do, but I can't recommend them for a high-end system.

The exception is the SXS 400W, which is made by CWT and is actually one of the best 400W units on the market.


There's also the OCZ Z-Series and Z-Series Gold. The Z-Series Gold (Z850M and Z1000M) are very solid Sirfa-made units that are all-around good performers and generally fairly priced. I'd put the Z1000M on par with the Corsair HX1000. The normal Z-series (Z650, Z750) have not been reviewed and are currently an unknown.


OCZ is also the current owner of the PC Power & Cooling brand, and are planning to start distributing the "PC Power Silencer MkII" PSUs soon. These power supplies will NOT be up to the same standards as the original Silencers, as they are no longer made by SeaSonic. It's been speculated that they will be made by Sirfa; however, this has not been confirmed.


Over all OCZ is a mixed bag. None of their current units are horrible; however, their most popular units, the XStream PSUs, get unwarranted praise and recommendations. Unless someone is on a tight budget it's better to recommend higher-quality units.

The 700W Fatal1ty is a really nice Impervio unit IIRC, and the ModXstream Pro 400W is also CWT

Edit: and I thought the ModXstreams were Sirtec? (I know the ModXstream Pros are, I think the regular ModXstreams are FSP like you said.)

Also, you've left out a lot of product lines! Less thorough than your other threads

What about the EliteXstreams, Powerstreams, Modstreams, ProXstreams and Evoxstreams?!

Edit again: I also thought the 400W and 550W Fatal1ty PSUs are Sirtec too...

Thanks for clarifying. I think the reason for their PSUs getting such high praise is because they make good SSDs and RAM. Good ram and good SSDs so why not good PSUs is what I was thinking originally. Thanks +rep

I agree with you there. one thing about the new pc power isn't it somewhat confirmed that it's a sirfa unit? The Z series was going to be a pc power unit butoin the end got the OCZ name on it. Didn't Sirfa change their name to High Power? With that said I can pretty much guarantee that the new pc power is a sirfa. under the smart fan it mentions high power's Intelligent fan or something like that.
metic: I think the original modxstreams were fsp the modxstreampros I'm pretty certain that they are sirfa units. powerxstreams were 3y power i think. Elitexstream I heard that they were fsp units.

This and they're cheap, for a reason of course. You could get the 500 for like $19.99 and the 600 for $24.99 6 months ago lol.

I'll agree,when you purchase a power supply,it should be one that will out last every other component you have.It's the one piece you can keep for many years and not be outdated.

That being said,people just don't want to spend a hundred bucks on one.So they sacrifice and get ocz.See it all the time here.

I just had a GameXStream 600W die on me after about 15 months, which apparently happens fairly often according to some of the posts I've seen here and reviews on NewEgg. So much for thinking a $95 PSU would last me a while.

On the bright side, my RMA with OCZ was a breeze - I got an RMA number and instructions in about 48 hours after a few emails back and forth. Mailed them the package and received a UPS tracking number for the new PSU after a 2-day turnaround. Performance might be a mixed bag, but at least they don't screw with you while you're under warranty.

Quick question. How does the fatality 1000 watt psu stack up against the rest?
I am need of a higher wattage psu as my hx850 died on me*I'm pretty sure it wasn't quite enough for my system despite what others say*.

It's an excellent unit without being a segment leader (performance wise), you wouldn't be making a bad choice by picking one up (depending on the price of course).

With that said , how does it compare the the zx series of the dame wattage.
Amazon has them both for about the same price I like the fatality one cause of the sleeved cables but the stickers are a nit too much. The zx is fully modular but not sleeved.
