OCZ Z1000M Overview (1000W)

OCZ's Z-series Z850 and Z1000 are the oldest available 80Plus Gold PSUs for high-end PCs. They're also the only OCZ models with 80Plus Gold in OCZ's range of products. Are they able to keep up with the more modern PSUs? We'll see, but OCZ makes their package a bit more interesting with a generous supply of cable ties, two power supply cable (for different power grids), and a nicely written user's guide. In addition, the standard 5-year warranty isn't too shabby. The Z1000M that we will review today is SLI-ready, has active PFC, and as the "M" suffix indicates it includes modular cable management. The PSU case has a length of 16cm.

Cables and Connectors
Fixed/Modular Main 24-pin 55cm
ATX12V/EPS12V 4+4-pin 60cm / 8-pin 60cm
PCIe 6x 6/8-pin 60cm
Peripheral 3x SATA 50-80cm / 3x SATA 50-80cm / 3x SATA 60-90cm
3x Molex 55-85cm + Floppy 15cm

There are two very long 8-pin connectors for the CPU, which is nice to see. In contrast to that the six 6/8-pin PCIe connectors are a common configuration for a 1000W PSU. We'd might like to see OCZ offer one more cable with Molex connectors, as there are only three on a single cable. All cables have a length of more than 50cm, and as usual the mainboard cables are fixed.

Globe Fan is the manufacturer of the large fan in the OCZ PSU. The model number is RL4Z B1352512H, a ball-bearing type with a maximum rotation of 1500RPM. This is a common choice Sirtec-manufactured PSUs.

Internally, you can see the typical Sirtec design with an 80Plus Gold configuration. We find the DC-to-DC converter, Infineon transistors with a low DS resistance, and a good looking EMI-filterung stage including a MOV. For safety functions OCZ uses a PS224 from Silicon Touch. The heatsinks seem to be small, but they should be enough for a strong cooled and very efficient power supply. Some outgoing cables on the left side are pinched by two cables ties, which isn't the best way of doing things but should work well enough.

    nice roundup though the outcome was predictable. I would have like to see some other heavy hitters other than antec included, i.e. mainly corsair, but also enermax, pc p&c, and maybe silverstone.

    I've been using mostly antec psus in my builds for a while. I like their low end series supplies, and the earthwatts series. I am running the SG850 in my personal rig. For my next personal workstation I plan to go bigger (dual socket). The antec hcp 1200 performs great by all accounts, but I have to say I would prefer a fully modular supply on a high end unit. The only thing I disliked about my SG850 was the cabling; it was also a pain to re-sleeve.

    Am I to understand that you want the fully modular cables for ease of sleeving?

    Thanks for the feedback!

    It would be nice to have a psu I didn't feel like re-sleeving. The sleeving on my sg850 was pretty atrocious. The hcp 1200 is a bit better.

    I'd also like fully modular because it's easier for me to make custom length cables, and not have to deal with hiding extraneous hard wire cables. My sg850 has both 4 pin and 8 pin 12v eps cables. Who needs a 4 pin eps cable on a high end power supply? At least make it a single 4pinx2 connector.

    The other advantage to fully modular cabling could be in balancing load across the rails as I need or want.

    I'd be happy paying a premium for an hcp1200 with fully modular connectors.

    The other comments are right, seems like a bunch of bigger names often synonymous with quality are missing from this review. You guys only review what the manufacturers send over for free now or what? I don't think I would buy any of these... Reply

    Thought it was kind of interesting that while the article mentioned the AeroCool's amazing carbon fiber exterior more than once, there were no pictures of that exterior in the whole article. Maybe that was to dissuade us from buying a terrible power supply based on looks? :)

    Also, in the Cooler Master review, it says that the fan has 7 blades, when in the picture it has 11 or something like that.

    I took the plunge and bought 3x 27.5" 1920 * 1200 monitors for use in an NVIDIA 2D Surround View setup and it's rejuvenated my love for gaming. I have 2x GTX 470s in SLI and need to add a third to be able to play all the games I want to in full triple monitor 6180 x 1200 resolution (bezel adjusted).

    I need to upgrade my PC Power & Cooling 750W PS to accommodate the extra power for the third card and this review couldn’t have come at a better time for me.

    I’m not a trust fund baby, just a lowly network administrator at an upstate NY community college who decided to invest a few extra $$hundred (okay, maybe a couple “few extra $$hundred) and try the world of Surround View gaming. I can’t recommend it highly enough if you’re a PC gamer.

    Did Antec pay for this review? Seems odd to include only bad PSUs for comparison. I.m guessing Antec chose the PSUs to test. Reply

    Not true.

    In a payed review you would see a Gold Award. ;)

    I'm sure there are more good PSUs and there will be more roundups in future. Maybe there is a PSU, which is better than Antec. Who knows. But I have to say, Delta is actually a very good manufacturer. So it is more the work of Delta I like, not the ideas from Antec. The cable management needs some improvements.

    Kind of a dark horse pick I guess but I'd really just like to see some more 'ink' on Powercolor's 1000w design because well, I haven't heard a bad thing about it yet, and the price is right. Reply

    Any PSU review without obvious king of the market (Corsair) is completely pointless.

    Who, in the right frame of mind, will buy AeroCool, Cooler Master or OCZ when Corsair cost is exactly the same or much less (at least where I live), Corsair offers superior performance in every price range when compared to any competitor, absolutely astonishing customer care and equally superior quality. It is complete no-brainer!

    In all honestly I would buy Tagan, Thermaltake or Enermax (even if I had some issues with them) over AC, CM or OCZ every single time.
