Well, after debating wether or not if I should get a new PSU I decided to go ahead and get one for this SLI setup. Not that I was having any problems with the current PSU I just wanna make dam sure I have the right amount of power at all times.

I have one as well, and it's barely enough to run my current rig (see sig), I would seriously consider returning it and getting a Powerstream 520 if you're running SLi.
 
The Powerstreams are more solid PSUs (more amperage on +12V). The cables on the Modstream are too short also.
 
Yeah, but you have to admit the Powerstream and Modstream are two totally different markets. Sort of apples and oranges, you know?

That said.... "cookie." :D
 
yah I was thinking of getting the modstream 520 too....cost over 100at newegg... it was looks/good performance vs antec's tp-2 550watt great performance and "ok" looks....I went with more power.. antec...but anyways


yah looks VERY BADA$$.....VERY... cables look short...but who needs long cables for hiding when they look so DAMN good....

I think they look tacky. :p They barely bend around corners, I had a lot of fun wiring up a Modstream 450W inside a TT Tsunami...

That is why you should have gotten the SuperFlower.......cables are really easy to route.....and 140mm goodness. :D
 
Not my machine, it was a buddy's, and he liked the bling-bling. I've got a Powerstream. ;) The two 80mm fans are very quiet... perhaps running at less than 1000rpm, they're Globe-branded fans, which are known to be pretty good in that respect.
 
I sort of did a speed read, but I don't see how it "didn't fair well" other than exhibiting a 5% differentiation on the 3.3V, 4% on the 5V and only 2% on the 12V in going from 93W to 502W versus a 3% differentiation on the 3.3V, 2% on the 5V and 2% on the 12V the Antec exhibited when going from 92W to 498W. Either instance was within the +/- 5% specification.

Sure, that means the Antec has tighter rails, but that's a power curve your PC isn't likely going to make. Even if it did, the 3% or 5% change in voltage would not be sudden and would likely have no effect on your hardware whatsoever.

What I see is the OCZ ran cooler and apparently at a higher wattage (although ONCE AGAIN the writer chose not to itemize their loads. He states the Antec went up to 530W and that the OCZ was loaded to the tester's "35A peak load" on the 12V, but didn't break down anything else.) The OCZ also ran at better efficiency at the wattage 90% of our PC's are going to be at under "normal usage" (between 200 and 300W)

Or is it the Power Factor your looking at? Because the OCZ doesn't have Active PFC.

I do think the Antec is better made, but I don't think it's fair to say the OCZ didn't fair well. The TTGI... THAT didn't fair well. 7% fluctuation on the 3.3V and 5V? Yikes!

The Enremax showed an average of a 5% fluctuation going from 98W to 463W and held a > 80% efficiency. Not too shabby.

I really wish these guys would break down their load, because it does matter what the 5V rail is loaded at while the 12V is loaded at 35A because a 5V rail that can't do more than 10A while the 12V is loaded up to 35A doesn't do me a whole hell of a lot of good, you know? And telling me wattage doesn't help. Case and point: A Thermaltaake TWV480 can do 480W... Just not where I need it to!

Thanks a lot jonnyGURU for pointing that out. Makes me feel a tad better about my purchase. What I really need to know is, will this PSU be enouigh for my system?
 
SWEET BABY!!!!! just plugged in my antec truepower 2 550watt and even though this is just software monitoring.. speefan.... 12.10 and 3.33 exactly :) woot.. alot better from my old psu.... smartpower 450watt.... 11.78 and 3.25 heheeh :)

well.... extremeoverclocking.com did a new review on this psu....didn't do very well either :eek:

this is the chart comparing its results to others.... I am just glad I grabbed the truepower 2 :)

I don't put a lot of stock in extremeoc's reviews ever. They passed the TTGI with flying colors last time, then this time they didn't......wonder if it was the same unit.......and it did reasonably well on the sunmoon.
 
Actually, the Superflower 550W I reviewed dropped as much as 12% going from 306W to 465W... BUT.....

We're talking about a 10A load on the 12V and 30A load on the 5V versus 30A on the 12V and 20A on the 5V.

That 30A puts the 12V right up to it's maximum specification.

That's why I question Extreme Overclocking methodology. What were the individual loads?

But yet at 554W, I got the 12V back up to 11.54V by pumping the 5V up to 35A.

See? It's all suggestive. And if you don't know the load on each rail, what do the numbers really mean?

That's why I shrug off the Ultra X-Connect at Trusted Reviews blowing up. What was the load on each rail? They never said. They only said how much total wattage the PSU was put under.

Hmm.... Food for thought.
