Jeffg010: I wouldn't say need, but the extra beef can come in handy if you are running a power hungry OCed setup with 3x video cards. Personally I bought it because I wanted to go modular and it was too good a deal to pass up.

Dolfan349: Glad to hear you finally got yours and it was the right one. Seems like most people who ordered it earlier got the right one and only a few assorted people got the wrong one as it trickled out of stock.

On that note, I STILL need to actually install mine 16 Hour work days are so much fun.....

Got it installed, the modular-ness is sweet. Only problem is the 8-pin ATX 12v cable is much too short to be properly routed behind the mobo.

Not too much of an issue as it can easily be corrected with a simple 12" extension cable.

It's also very quiet, which is a nice bonus.

Unfortunately, I will be returning this power supply, as it squeals and buzzes when SLI is used in all of my games, during 3dmark benchmarking, and even while Windows calculates its performance evaluation. I understand that this isn't harmful for the system, but I can't get over the sound it generates. It's really too bad - the price was great, the finish was attractive and the modular cabling was fantastic.

I have noticed the noises as well. It doesn't seem to persist during actual gameplay, though. Only during startup movies and the first few 3DMark tests. And most importantly, it's silent on the desktop.

I'm also running SLI, btw (2x GTX 470).

EDIT: Anyone else's make an audible "click" when first powering on or shutting off?

I still haven't had a chance to check mine out, but JonnyGuru did note in their review that it made some noises when loaded with an SLI setup. The thing that stands out to me as odd from all the user reviews I have read is it seems to be certain combinations of cards causing the problem.

I have tested with a 4870x2 and 2 6950s and didn't hear anything over the noise from the fans.

This deal seems to be on again

JonnyGuru reviewed the 1000W a week or so ago and gave it a 9.5 FYI

Jumped on one today, glad to hear everyone is getting the proper units.

Was going to get an AX1200, but this has identical specs and is $100 cheaper!

This is nothing like an AX1200. Not even in the same ball park.The AX1200 is made by flextronics custom made to order. Very high quality. The OCZ doesnt even come with a MOV so you better get a really good surge protector. The internals escape me, think i read its the same insides as sparkle?

Please get your facts straight before commenting.

these facts?
"Upon opening the ZX 1000W, we see a PSU that it is actually built by Great Wall. The Sparkle 1250W we reviewed some time ago was also a Great Wall build."
"The AC transient filtering stage starts on the PSU housing with an X capacitor and a pair of Y capacitors. The transient filter is continued on the main PCB with two more X caps, two more Y caps and a pair of coils. There is no MOV."

And your point is what? That the overall review is garbage? Did you read his conclusions? Why aren't you posting that too? If you don't like this PS then please don't buy it.

BTW- if you bothered to read this whole thread you would have seen that it was stated before that great wall makes this PS. We already knew that much.

In addition this thread is not about a comparison of Corsair PS vs this one. Everybody knows Corsair makes great power supplies but the one you list is $280 +$12 shipping at Newegg so this is $100 less (for now), is high quality, well reviewed and has a 5 year warranty.

I was simply informing the person who had walked away from the AX1200. You got something kinky goign on with OCZ whats your issue? If you had bothered to read my post i said i had forgotten who made the insides but believed it was the same as sparkles. Then you told me to get my facts straight and linked me the review. so i looked at the review and quoted the facts you told me to get straight. THAT was my point.

I fail to see why your taking this so personal when i simply tried to inform someone of the AX1200 that they brought up and why this PSU was cheaper. Didnt want them to think it was $100 cheaper for the same thing. Relax, take a breath , have a beer wow.

Edit: oh now i see why you are takign it personally you own it and must justify it to yourself. Whatever makes ya happy.

@SininStyle

I definitely don't speak for jzodda, but I believe his point is that this is a hot deals forum and you are making it sound like this PSU is complete garbage. Based on the legendary status of the Corsair, no one can argue that on paper it is the superior unit from a pure performance standpoint; to the best of my knowledge, nothing outperforms it. That being said, this unit stands up well, and I seriously doubt in real world usage most people would be able to tell the difference as both are seriously capable PSUs that push the hardware limitations to the ceiling. I simply cannot imagine a usage scenario where someone could find something with one PSU that they would not be able to do 99.99% equally with the other PSU and get similar results. Add to that a $100+ price difference and the choice is easily made for me.

Regardless, I hope anyone who got in on this deal is happy with their purchase. I know I am.

And my point is simply that its not a "Hot" deal as i feel as this power supply should be at this price mark.
No MOV, cap whine, doesnt make gold spec, it goes on. Grats to those who bought it. Never said it was garbage. Just saying you get what you pay for in this scenerio.

For this much money i would have waited for a sale on another unit without the drawbacks that is all. A true "hot" deal.

It IS a hot deal, and most would agree that it is. You say it doesn't make spec but Guru reviews it and gives it a 9.5. So you are claiming you are more knowledgeable then his review, the most credible PS reviewer around? yeah ok smoke some more..

Plus I do own this Power Supply-thanks to this very thread. I have run 2 4870x2's and 2 GTX 580s without issue in a heavily overclocked system. No noise, no whine and no problems. How much experience do you have with this unit? none.

Your new around here but you are violating forums rules. Please go read the rules in the sticky post.

"No thread crapping. If the subject matter of a deal does not interest you, do not post negative comments about it, or about other members, in the thread."

He is technically correct that it missed the gold rating by about .5% (looking at various other review sites, JonnyGuru seems to just round off) on the 50% and 100% load tests.

"Since this PSU is supposedly 80 Plus Gold, we should see at least 87%, 90% and 87% efficiencies during test 2, 5 and 8. And it looks like we miss that by 1% at 50% and 100% loads, but it's not uncommon to get a 1% difference between two of the same units. One thing that was good to see was the PSU was still at least 80% efficient even with a load as low as 100W on it. Usually you see a power supply's efficiency completely tank at extremely low loads."

In real world terms this means that at 100% load running 24-hours a day this PSU will end up costing the difference between the Corsair after a mere ~25 years of use (30 if I don't try to account for inflation and rising energy costs).

I also find it telling that JonnyGuru gives the ZX-1000W a 9.5/10 in value at a cost of $189.99...

Edit: Also, I don't want to chase someone away for thread crapping if the intention is a bit of spirited debate. I do however ask that an attempt be made at posting a reasonable alternative at a similar price point.

Sorry my intention wasnt to thread crap honestly. Someone stated they were looking at the AX1200 and walked away from it for this because " it had the same specs". Well there is a huge difference between the 2 and thats all my intention was. to inform that person that this is cheaper because of those differences.

Thats when i got jumped and burned at the steak which is fine whatever. I thought i was helping someone lacking information when i guess i was crapping all over this product without actually saying anything bad about this product.

Anyway as far as price point this wattage is overkill more time then not for everyone buying them. the 1% with quad SLI that actually need this wattage dont need to steak me and set me on fire. At this price point i would look closer at lower wattages with better efficiency. I would just wait on a sale for the usual suspects like seasonic , corsair, antec, the proven front runners.

JZ it seems you only read the last page of reviews. i would suggest reading the entire review when you tell me to double check my facts. You link the review i should be reading then jump me when i quote the very facts from that review to prove my point you said i missed. Just because he rates the 1000w unit a 9.5 or whatever you really should read what stopped it from being 10 and decide if those points matter to you. For me it misses to many things and would rather down grade wattage for a better quality PSU that meets spec.

I guess my sticking point is that you keep saying there is a HUGE difference between the two where I simply don't see it. +/- 1% efficiency doesn't do it for me and I have yet to hear any whining from two units both of which have been loaded down with some power hungry hardware. I understand that on paper there are better units, but what does all that actually equate to in the real world? What tangible effect does this have on absolutely anything anyone would be trying to do with these PSU's, especially at this price point?

As for being more PSU than most people will need, I agree entirely. As you can see by my signature I am not coming anywhere near maxing this beast out. That said, I have tried to take into account capacitor degradation over time as well as future upgrade possibilities. I like being able to just buy whatever hardware I want without having to bust out a calculator to make sure I'm not going to destroy the PSU. Ultimately, I see no logical reason in paying $150 for a PSU that is rated at half this power output. I can always use less energy than a PSU is rated for, but the inverse is definitely not true.

I have NEVER seen such a quality and capable PSU go for such a low price, regardless of sale, coupon or anything else shy of theft. If you have, please point it out, even if the deal is expired so I can fill in any holes in my knowledge of the going rate for hardware. I consider myself a connoisseur of the price-to-performance ratio paradigm and it would be a great failing on my part to not be aware of such a great deal.

As far as being "jumped and burned at the steak" I think that might be a little melodramatic, but maybe that's just me?

I believe its also mentioned in jonny gurus review. may have been techpower im not sure now.

burned at the steak is no more exaggerated then me being a thread crapper when all i did was state they wernt the same spec.

you can get the 850w version for $100 on egg right now. that pretty much puts the 1250w version in line for $180. Can find silverstones and some corsairs in this price range in the 1000w range. Of course they are silver rated. I bet they come with MOVs and no coil whine though.

Ill be honest i havent shopped this wattage bracket at all not even for a second because the wattage is so beyond my needs i see no point. I only looked at this thread because of the price which seemed like a good deal for the wattage so i looked at reviews. Now i feel like it should be the normal price.

I shop 850 watt bracket far more because it makes more sense for a system like yours or mine. your system for example is prolly around 650w total maybe 700w if you have those gpus at 900mhz. So take a 850w and figure in your cap degrade. which is less with good caps like in a seasonic or corsair.

With platinums filing out i think this is just the beginning in price drops in golds. And i believe the AX1200 comes with a 7yr warranty and this OCZ is 5?

If a ABS 1200 gold or something was marked at $150 would you say it was a good deal? I just think the OCZ gold cuts some corners and it should be priced at this point and dont see it as a good deal. spend more money you get better quality. thats all im saying. not saying this is crap, not saying its not worth $180. Just saying its not a hot deal.

And by the way i am not "new" ive been watching these boards for yrs and yrs prolly 6 times a day. I just dont post. One day i had to make a post so i had to register to do it. This is also just one of a dozen sites i look at daily for deals.

This.

The difference between this and the AX1200 is not worth mentioning given this thing's price. Is it the same? Ok, I guess not, but come on, let's not get carried away. The posts in here make it sound like the AX1200 is in an entirely different league.

God its like arguing with a 2 yr old.

I originally replied to point out to someone one this thread who walked away from the AX1200 for this WHY it was cheaper. When they thought they were identical.

You must use something else as a reference to get an idea of value. This is $100 cheaper then the AX1200 which i feel like should be the normal price and dont see it as a deal because of the corners cut. One of which is spec, you can find silvers in the same price range with higher quality and longer warranties to back it.

Buy it, dont buy it, I dont care. My only purpose was to point out to the person who walked away from the AX1200 WHY this was cheaper, that is all. Im sorry that has offended your epeens.

Im done. enjoy your OCZs

Where can you find a silver 1200w+ PSU with higher quality and warranty within the same price range? I've been living under a rock if what you say is true.

In any case, I was convinced this was a price mistake when I purchased it. I am very happy with this PSU.

To make this as easy as possible I am going to try to address your points one by one. My intent here is not to be rude, but I think this might be the easiest way to reply.
you can get the 850w version for $100 on egg right now. that pretty much puts the 1250w version in line for $180. Can find silverstones and some corsairs in this price range in the 1000w range. Of course they are silver rated. I bet they come with MOVs and no coil whine though.
The 850W OCZ would cost me $123 after MIR on Newegg right now. That being said I'm not sure why you would choose a PSU in the same product line you appear to disapprove of to justify the price of the unit in question in the thread.

As for there being similarly priced Silverstone and Corsair (I am guessing here, please feel free to correct me) units I don't really see the comparison. The OCZ beats both units in total power output, price, effecieny, modularity, and connection options. It also beats the Silverstone warranty by two years, although it admittedly falls short of the 7 year warranty offfered by Corsair.

On a personal note, I place very little value on the inclusion of an MOV as I have a decent surge supressor and have never run into any issues. Also, I have done a test run where I loaded down the PSU with 3x Geforce 580s and did not hear any coil whine. I assure you if I did I would have sent the unit back as I find that absolutely unacceptable. That said, if I can't reproduce it in the real world with one of the most power hungry setups, I consider it a non-issue.
Ill be honest i havent shopped this wattage bracket at all not even for a second because the wattage is so beyond my needs i see no point. I only looked at this thread because of the price which seemed like a good deal for the wattage so i looked at reviews. Now i feel like it should be the normal price.
I shop 850 watt bracket far more because it makes more sense for a system like yours or mine.
Totally understandable and in fact I am for the most part in the same boat. I only jumped on this because I felt it was too good a deal to pass up. I did plenty of research before I jumped in and what I came up with says that the only thing that matches the features and price point is (drum roll please) the OCZ 850 Watt previously mentioned. As a matter of fact it works out almost perfectly and has about 68% of the power output for 68% of the price.

I am sincerely interested in your personal opinion here. As a fellow PC enthusiast the information that you have might be useful to me even if I don't necessarily agree with your assessment. I am always open to learning something new, so I ask, nay emplore you, to please link me your picks for ~850 Watt PSUs in the ~$130 price range. I assure you this is not a personal attack and if you'd feel more comfortable a PM would be completely fine, I am just interested in your opinion.
With platinums filing out i think this is just the beginning in price drops in golds. And i believe the AX1200 comes with a 7yr warranty and this OCZ is 5?
I think you might be overstating this a little bit. The highest output 80 Plus Platinum PSU I am aware of was only recently shown at CeBIT and it is limited to 850 Watts, which is quite a bit less than the OCZ. The rest that I am aware of can be counted on one hand and are all around 550-600W.

On the warranty side, the Corsair wins hands down, although I find it interesting that you seem to give Silverstone a pass in this area. I've personally had two Silverstone units fail on me and I was denied a replacement because I did not have my original receipt after 2.5 years.
If a ABS 1200 gold or something was marked at $150 would you say it was a good deal? I just think the OCZ gold cuts some corners and it should be priced at this point and dont see it as a good deal. spend more money you get better quality. thats all im saying. not saying this is crap, not saying its not worth $180. Just saying its not a hot deal.
If I see any hardware that is proven to perform in the top tier while being priced in a tier much lower, I am interested. That would go for the ABS if any information led me to believe this unit had anywhere near the quality of the OCZ. My guess is, we can both agree that it is not. To be perfectly honest I try to go where the performance/price barrier meats and I would buy a PSU made by Fisher Price, Quaker State, or Betty Crocker if I thought it was the best option. I place very little value on brand name, especially as the majority of the PSU market is outsourced to other companies. Hell, even Corsair is fallible if you look at some of the choices they've made in their lower end units.
And by the way i am not "new" ive been watching these boards for yrs and yrs prolly 6 times a day. I just dont post.
I think this was targeted at someone else, but I am right there with you. I've been an Anandtech user for something like 9 years now. I just never registered until I wanted to post a deal
