OCZ ModXStream Pro 600W Modular High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7 and AMD Phenom

Pros: Very quiet running and has a good selection of power cables and connections.

Cons: The secondary motherboard power supply line is rather short. This would not pose a problem in a top mount, but it is pulled almost tight in my bottom mount case.

Other Thoughts: Avoid this p/s in anything but the smallest of bottom mount mid-tower ATX cases.

Pros: Modular design is nice.
Had no issues until it failed.
Did NOT take out anything else (hard drive, video card, etc.) when it died.

Cons: Lasted only 3 months past warranty expiration.

Other Thoughts: The warranty for this power supply is 3 years, and mine lasted almost exactly 3 years and 3 months. It died with a "pop" and an acrid smell when I went to turn on the machine last weekend. After replacing it with a new power supply it appears that it did not damage anything else (hard drive, video card, etc.) when it died.

Reading through some of the other reviews it appears I'm not the only one to have it last just beyond the warranty period. So keep that in mind if considering to purchase - works great for 3 years, but after that you may need to start thinking about a replacement.

Pros: Worked throughout warranty period

Cons: Exploded immediately after warranty expired

Other Thoughts: What else should I expect, I suppose?

Pros: This power supply is clean, efficient, reliable, quiet, and capable.

Cons: Wish it had some different cable selections with it

Other Thoughts: I just wish it had a cable that had only a molex on it.

Pros: I've owned this for more than 4 years on my computer, and I have to say it's performed extremely well. Quiet, reliable, and it powers everything I need. Modular plugs makes cable management easier. Also works well with my fan controller (I have a Corsair 600T White)

Cons: Some cables may be a bit short (though that may be in part due to the size of my case/gpu), so it may annoy anyone who may be a bit more OCD about cable management. But that's not really a con in my case.

Other Thoughts: I've only really needed a max of 600W on my computer, but if I ever were to need more, I'll certainly buy another PSU from OCZ.

Pros: Good cable and connector selection

Cons: Failed with no warning (verified w/power supply tester and new power supply) several months out of warranty.

Other Thoughts: Used in a desktop office setup, 1-2 hours a day. Never had a p/s fail before, even using the bargain basement cheap parts.

Pros: It's alive! Works great and keeps quiet.

Cons: I'm using it with a NZXT Phantom full tower and the cords aren't long enough to stretch behind the grommets in the case and out through the top to keep the inside looking clean. Instead I have to run it right across the Mobo and even that is kind of tight. Could defo use with a couple extra inches. Took off a star for that.

Secondly, I bought this with a rebate and I sent it in with every piece of info required and then got a rebate denial letter for not providing the correct tags. I sent them every single bar code I had and wasn't happy about that. Had I known I wasn't going to get the $25 rebate I'd have bought a slightly better power supply and called it a day. Took off another star for that.

Manufacturer Response:

Dear Dan,

Thank you for your feedback regarding this PSU. Each PSU has varying cable lengths designed to fit your intended usage environment. The mainstream ModXStream Pro Series has an 18" CPU power cable where a Prosumer model like the ZX Series use longer 22" CPU power cables. It is fine to use an extension cable as long an you verify the extension cable specifications and match appropriately. Feel free to contact us using the link below for any assistance.

Regarding the rebate, I am sorry to read of that. The rebate house is very specific in what requirements must be met and proof included. If you believe this is in error please contact us at this email address: rebates at ocztechnology dot com or call us at 1 (866) 876-0856 M-F 9AM-6PM PST (say "representitive" when prompted). We will try to help however possible.

Thank you again for your purchase!

Pros: Modular
Big Quiet Fan
600 watts

Cons: Could have a few more cords and plugs for extra hardware

Other Thoughts: I bought one of these to run on a small desktop / game server. It was running a Super Micro board with Dual Intel Xeon cpus and a small handful of hard drives.

It had run for 2.3 years almost solid 24/7 ( save for a few reboots and power outages. Today however, I powered down my machine and did a little maintenance and swapped out a drive. Upon trying to power the machine up the PSU greeted me with flash, bang and a little bit of party smoke.

I am currently already writing to their tech support, if all goes well I will come back and give this supply a fresh review.

Overall I am ok with the time I got out of it, it's just inconvenient that it failed on a Sunday and I am without my game server until at least tomorrow. Though I guess it's not so bad since it did fail within warranty, hopefully it's replacement will treat me better.

Random side note: I am an electronics technician and small network admin by trade. I have worked on 100's of computers and other types of machines and the one thing I will state is that anything can and will fail. I have went through countless components in machines. The only thing I have really concluded is that you do get what you pay for. This was a decent mid-range PSU and unlike alot of CHEAP psu's I have run into, this one did not ruin my hardware when it failed, it only failed itself. This review is bitter sweet, I am out of a PSU for a few days, but at least I am sure I will get it replaced.

Pros: Cheap, 80 plus and semi modular

Cons: Cables are way to short. You have to buy cable extensions. My case is not even considered the tallest. It's only a midtower.

Other Thoughts: I kinda regret buying this psu. Should had paid extra and went the Corsair TX

Manufacturer Response:

Dear Valued Consumer,

I am sorry to read you regret purchasing this PSU. OCZ does provide full diagrams that detail the length of each cable so you can determine if it will accommodate your particular chassis. Different PSU models do carry different cable lengths. I will post a link below so you can explore the various diagrams for future reference.

Thank you for your purchase. If we can be of any assistance don't hesitate to contact our Support Forum.

Sincerely,
OCZ Suppor

Pros: it looks nice
love that it is modular

Cons: After 2.5 years of service when idle or on load the unit makes an extremely loud noise.

Other Thoughts: I contacted their RMA center and this is the response I got:

"Try running GPUTool on your system. If the noise intensifies or seems to follow the spinning rings, you may have coil whine.

Try enabling VSYNC or double/triple buffering in the games and/or in your video card's management software. This can reduce the noise and sometimes eliminate it completely."

Anyways, I would not purchase OCZ products again. This response is from a "TECH." How does this even solve my inherent problem? This sounds like more of a patch than real help. Maybe they are too cheap to give me their "3 year warranty PowerSwap," so instead they tell their customers how to patch their problems until their warranty ends.

Manufacturer Response:

Dear Anonymous,

I believe the tech was trying to determine the cause or reproduce the noise, not necessarily provide a permanent workaround. Regardless, I would like to investigate this further. Please send an email to me via rcampbell at ocztechnology dot com and include the following information:

Thank you and I look forward to hearing from you!
