View Full Version : OCZ powerstream - silly q? maybe..
Sorry if this is a silly question, but here it goes:
I ordered the Powerstream 520, it had to come from another store and I didn't want to drive. In any case, they called me and said it was in, I picked it up. However, when I got there, the PSU came in an orange box and has the green LED! I bought it anyway, and I can return it as long as I don't open it. So I am asking whether this PSU and the one with the blue LED are exactly the same (design and functionality) aside from the green/blue LED?!?
Here is the PSU and the store I bought it at, the one on the picture is clearly the new blue design, but they gave me the green LED one.

I really don't care about the green LED, in fact it probably looks nice, so this is purely about whether I am being ripped off or if there is anything different about the green model over the blue one. Thanx.

The blue one changes fan color to blue, and adds a second PCI-E connector. Otherwise, no other changes have been made to them.
adds a second PCI-E connector? But both say SLI on the box, so what exactly does this mean? So they are not the same afterall?
And if that is the diff, is this something that can be added to the green one or is it something the green one just has to do without? If this is not about SLI, then what exactly is a PCI-E connector?

There are two units that are exactly the same PSU.
One is a OCZ520ADJ. This model has the green fan, and comes with an adapter "splitter" to use for a PCI-e SLi setup. This is the older of the two models.
The other is a OCZ520ADJ SLi that comes with a blue fan, and has dual PCI-e cables already and no longer requires the use of the adapter "splitter".
They are both the exact same unit. They have the same specs, and are the same strong 12+ single rail unit. There is no difference at all in the internals of the two units.
The only differences are from a looks standpoint, and the added PCI-e cable. If you are running a SLi setup, I would go for the newer unit, as it is more electrically sound. It's better to have a big cable to carry the juice, than to split one using an adapter. Other than that, you will see no differences in performance or overclockability. These units are *very* strong.

Thats funny cuz on the Box, it says OCZ-520ADJ SLI on the back with specifications. Furthermore, it has a big SLI READY sticker on the front, and on the back it says:
"The OCZ PowerStream also includes 2 connectors for high end graphics cards, 2 connectors for PCI Express, and 2 Serial ATA connectors on two seperate cables" exactly as quoted here.
So, whats going on here?
btw, the box is orange.

I'd have to say someone put the wrong version in that box. I think I would go back to CC and get them to exchange it.
I haven't opened the box yet, what I am saying is that on the box it says what I wrote above, but on this same box is also says SLI and the picture of the PSU is with a green LED!
I opened it anyway, and its the SLI version, for sure. I don't know why the box has the green LED, but the PSU inside is the real deal <wipes sweat off forehead>
Of course you guys did give me some false info, the damn thing is HUGE! I don't think I'll fit it into the P-180 while keeping the stock PSU fan of the case where it is (center of the bottom chamber). Oh man, this is ****ing me off already, but the PSU looks awesome.
Ok, the fan in the bottom chamber designed to create air-flow in the PSU/HDD area had to go. There is absolutely no way it can fit with the PSU in there, the P-180 must be made for regular size PSU's, and the Powerstream is very long.
So, I have this pretty trispeed fan sitting here now.
Is it ok to run HDDs without direct airflow? The only thing in the bottom chamber will be 2 HDDs (about 1 inch from the side of the case each, and 2 inches apart from eachother) and the PSU which has a fan blowing into the PSU from inside the case, and a fan blowing air out of the case in the back. I figure this will create some airflow, but not sure if its going to be enough to keep the HDDs in their operating temps. Are HDD's designed to run at room temperature without airflow? I think they are in which case it won't be a problem, especially since they'll be 3 inches apart from eachother.
Thanx for the help.
ps. whats the thinnest 12cm fan on the market? I think if there was one that was a half-inch thick it might fit in there.

They will be getting airflow thanks to the two fans in the PSU - the P180 is designed for that extra fan to be used with a fanless PSU. I wouldn't worry about it not being there in your case.
If you think that thing is huge, you should see my Fortron 530w with that intake fan mounted to the outside - now that's a long PSU (unless you compare it to a Zippy 700w or PC P&C 850w & 1kw).

It's really not a problem without the fan. The PSU really isn't that huge. You should see the 1100watt OCZ demonstrator they came out with. It was almost trwice as long as what you have now! LOL
Actually that OCZ you have now, is a regular sized unit. Those other little baby things are so small becasuse there's nothing in there. hehe
I have an OCZ520ADJ in a Xaser III Lanfire midtower, so you should easiily be able to put that thing in a P180. It was all I could do to get mine in that case, and get all the wires tucked away nice an neat.
If you think the thing is pretty now, wait until you run the system with it. "Pretty is, is pretty does". That unit is not just some looker with no brains...it's got the looks that kill! LOL That PSU will never even get warm. You can clock a CPU 5GHz+ and you won't load that thing. It's a beast.

They use the same picture of the old green-fan model on the box for both the regular OCZ and the new blue-fan SLI version. It can be misleading.
Good news! The big fan that was in the bottom chamber is going to get good use! I didn't want to just throw it away.
It fits in the upper chamber in front of the upper HDD holder! I had to use a couple washers so that it doesn't rub against the dust-screen (which I wanted to keep), but it seems like its a perfect fit.
So now I have a 120mm exhaust fan in the rear, a 120mm exhaust fan in the top, and a 120mm intake fan in the front upper chamber.
The bottom chamber only has the PSU creating air-flow, but it should be enough as that chamber will only have 2x250GB maxtors, about 3 inches apart from eachother.
I will also add the 80mm video card fan if the computer needs it, we'll see after I clock it all to the max and record the temp.
Thats a pretty heavy duty stock heatsink/fan combo that comes with the Opty 165, but I am guessing I'll need aftermarket asap.
