Oh man! I can't wait to hook this up and play Doom12 on my awesome babe-repelling custom-built geek machine! It's gonna be so radical that no one will come close to my awesomeness!
Hahah...yeah! That's what #2's gonna say!
It's a PS for 1/3 of what a Dell system will cost. How many consumers really need this upgrade?
... speaking of which, does anyone know a good case that will support two ATX power supplies? I'm thinking a full tower Chenming might do the trick.
I will wait for the plutonium powered towers. The glow it gives off should really be cool.
well considering I bought the OCZ 520 with adjustable rails for $140 like 2 years ago, I think this is a very good price for more power for less.
#3, the CoolerMaster Stacker (Not the 810 or the 830, it's the one they put out first) handles 2 ATX PSUs.
If you don't want it why are you posting comments on this? You obviously are inept and cannot do anything by yourselves. And btw, a dell system that costs $300 is a POS unless you just want to surf the web and not do anything else. This powersupply is quite excessive but the price is right.
Good one #1, LMAO!
#4, those are already available in Iran.
Competitive with other 7-odd Watt PSU? No.
Competitive with other $110 PSU? Maybe, ask again in a year when we have some data to know whether they last at higher current.
Dr. Morbius, since you are going a custom route with two full ATX PSU anyway, you might consider buying the full tower case you want instead of trying to find one that takes two full (PS2 sized) PSU, because in general the vast majority of cases are not set up to use two full ATX PSU.
Some full towers are set up to be able to use two redundant PSU, the modular stacked type. Chen Ming for example may have a removable plate that adapts for PS2 size or allows use of the redundant when the plate is removed.
To use two full ATX on a typical full tower you would take a piece of cardboard, cut to size and put inside the rear wall of the case. Trace out the cutout for the first PSU including the screw holes. Next cut out what you'd traced on the cardboard and use that as a template to mark where you will cut out the rear case wall to accept the top PSU.
Such a modification is relatively easy if done while case is still empty, using a nibbler tool on thin-walled cases (0.8mm thick sheeting or less), or a sabre saw with a very fine toothed blade. For a full tower case and enough gear (value of equipment) to need two PSU, I'd advise investing in a case that has at least 1.0mm thick sheeting, even 1.2mm or more if aluminum.
I don't see why you would need a 700W PSU if you'd be adding another one though, two reasonable quality ~ 420W @ about $50 each will run a quite well endowed system, more than you might think since having two PSU doesn't just up the continuous, sustained amperage available, it also (depending on load per each) halves the heat density and doubles the airflow (which is partly why it also ups the sustainable current).
unfortunately, this isn't all that great of a power supply. This power supply is manufactured by FSP, a manufacturer known for their output voltage ripple problems, and they don't disappoint with this PSU.
Ripple on the output power is a silent killer that can destroy many of your components. It stresses and can cause premauture failure of your voltage regulators that regulate power to your CPU and GPU, among other things. So, using a power supply, like this one, with high ripple, could cause your motherboard and graphics card to fail. Also, since ripple stresses the VRM's, it can hinder overclocking.
So, the ripple on the 12v rails of this power supply exceeds 150mV. ATX specs allow for 120mV, but lower is always better. Here is a shot of the ripple on the 12v rail:

ugly, isn't it. That's over 150mV of ripple, way over ATX specs. Now, to compare, here is the ripple on the Ultra X3 1600watt power supply, when loaded to approximately 1600watts, over double the load on the GameXStream from the previous picture:

That's under 20mV, at 1600WATTS!

To look at something a bit cheaper, here is the ripple on the 12v rail of the Rosewill RP500-2 power supply, a budget power supply that sells for somewhere around $50, retail:
[image]
that power supply, at full load, stays around 20mV ripple on the 12v rail.
The GameXStream line is flawed, it's not just the 700watt unit. The GameXStream 1010w power supply can't even run at all at more than 85% of it's rated wattage, it just shuts down. Also, since it was also made by FSP, it also has ripple problems, with all of it's rails(3v, 5v and 12v) going way above ATX ripple specs.
Basically, don't buy a GameXStream. If you do, you risk burning out your the voltage regulators on your motherboard and graphics card. Do you really want to buy a replacement graphics card? And do you really want to have to pull all of your components out so you can install a new motherboard?
Just buy a higher quality power supply.

There are some other lines of power supplies that OCZ sells that are of much better quality, but avoid the GameXStream and ModXStream models. Their ProXStream, ModStream, and EvoStream power supplies do not have ripple problems.
You could get this power supply and use it as a 400-500watt unit. The ripple would still be very high, but not out of spec. As long as it doesn't increase, you'd probably be fine. However, since very few people own an oscilloscope, it's very hard to check to see if the ripple is too high. So, you might get a slightly worse unit than the one that was reviewed, that happens to have ripple exceeding ATX specs at 400watts, and you'd never know it, until your components started failing.
But, why would you want to pay $100 for a mediocre 400-500watt power supply? There are far better power supplies available for under that price that provide plenty of watts of nice, low ripple power.
the above pictures are from power supply reviews at [H] Enthusiast and JonnyGuru.com.
I have to post an update on this power supply. The OCZ rep that has recently joined these forums has told me that the ripple problems on this power supply have been fixed. Apparently, the initial sample units that FSP sent OCZ tested out fine, and fully in spec. But, the ones being sent out to customers had out of spec ripple. When OCZ found out about this discrepancy, they had FSP fix the problem.
So, if this is true, then this power supply is probably one of the newer units with the ripple problem fixed. Also, I'd assume that they didn't mess up the voltage regulation which was already very good, so, that's likely fine as well.
However, I only have this one rep's word on this. I have yet to see any reviews confirming that the problem has been fixed. If anyone does know of a good recent review of a GameXStream or StealthXStream power supply, please link it on here. I'd like to confirm or refute this statement as soon as possible.
