Seasonic 600w or OCz Powerstream 600

[mion]

proably everybody know about ocz so no introduction needed

Link for seasonic

Features that LIke about psu
Efficiency up to 80% (ocz is only 70%)
Suppose to be quiet
Cheaper than OCZ


Finally have the answer for this question but if anybody is checking it here comes the answer:
System Spec that this based on
AMD 939 Venice 3500 250x11(2750) 1.65v
Dfi Nf4 Ultra
1GB Redline 4000 at 250 ratio 1:1 3.3v
Sound Blaster ZS Gamer
x800xl
Nec Dvd burner
Samsung cd/burner
74gb raptor
200gb maxtor hd
160gb seagate hd
6x 120mm fans
mcp 655
nexus fan controller

Seasonic Results after 12hours of priming (torture test, number 2 large fft), voltmeter readings
Idle
12v= 12.02
5v=5.00v
3.3v=3.33

Load after 12h of prime, still under load
12v=12.03
5v=4.99
3.3=3.30

Rpm level
Idle 1000rpm
Load 1100rpm -1200 RPM

Ocz Psu Results
Didn't run any, the noise scared me away. I checked with voltmeter and the readings were strong so I really doubt under load it would drop under specified. On the other hand Noise level is a Killer this psu wasn't silent at all.

My Conclusion

Seasonic, good pefromance and quiet operation, big winner in my opionion, but I didn't run SLi, so can't say how much effect it would have on rails. 5v rail goes below but only by .01 so nothing to worry about, might go more maybe if ran in sli though am not sure about it. But for my requirements it's enough

Ocz, Loud, with this psu you won't be needing to upgrade in the future, rails solid as rock, also if you run this psu you don't need fan controller

I recoreded some audio of both psu, how loud they are without any hardware attached to them.

Imo go for the powerstream but go for the 520w version it'll be more than enough for that system

[The Mofo]

PSU, buy for the future. Powerstream 600 all the way.

[b|gf|sh]

Seasonic 600W all the way :)

Some of the reasons why I got one: -

>80% efficiency, Active PFC, 120mm fan (Should be quieter than the 2 x 80mm's in the OCZ), 2 x 150W PCI-E connectors, 8-pin ATX connector, 4 x SATA connectors...

I pre-ordered an S12 600W and got sent an OEM 600W by mistake, so cant test this one because its going back, but looks like its gonna own my 300W fortron ;)

[P_1]

seasonic unreliable? they are a highly rated brand over at silentpcreview

[dreamworkz]

this seasonic psu looks sweet! the specs look awesome and the 2x pci-e connectors are good to have...I wonder if this has adjustable pots? I wonder if anyone has this psu could report back...

I have the seasonic S12 600W, SLI... it is great... really stable rails, well without pushing a graphics card... but my cpu at 4.3ghz it still maintains it's rails stablitiy at load...12v rail is at 12.01, 5v is at 4.99, 3.3v rail is at 3.27.... so thats not too bad... they dont move around

there are no adjustable pots... kinda bummed out about that.

im moving to SLI soon... so that should help torture this thing abit :D
and i upgraded from a OCZ Powerstream 420W that i've been using for a few months

dont trust mobo readings, i built my friends rig today with a pcpower and cooling 510 sli and in the bios it showed the right readings but inside windows speedfan was showing that the 12v rail was at 11.87 and the 3.3v rail was at 3.27, completely off.

are those voltage reading done with volt meter or bios reading

Thanks bro...I think the dual pci-e connectors is what has me wanting this. I know that the OCZ is awesome but only one pci-e connector. :( and I dont feel like using 2 4-pin connectors to connect a future card to it...but again thanks again bro for your input...

That is great reasons to by an powerstream! On the other hand the price is a down side.. I would for my own system spend to money on the powerstream, as I hate to end up with weak rails, and are able to adjust them with OCZ..

Seasonic = unreliable. Nuff said.

Seasonic makes very good PSU's, but not close to the quality of OCZ's PSU's.

[mion]

I found the answer, ocz is good but to much hassle with it, I am keeping seasonic, which I posted in the first post of this thread, You can also hear seasonic vs Ocz

[jinu117]

Seasonic unreliable? Where did you get the idea?
Just ask ANY major hardware retailor or distributor who sells variety of PSU and ask them... Only reason seasonic might not be on plate for their build might be the cost -_- and usual lack of bling factor. Just look at some old PSU reviews and find out how well does Fortran and Seasonic does in comparison to most 500W+ PSU back a year ago (talking about 350W unit of Seasonic and Fortran matching up to majority of 500w+). I still have 2 seasonic running on my rigs that are running as good as when I bought it 2 years ago.

Seasonic = unreliable. Nuff said.BS! :slapass:

The Seasonic S-12's are very good PSU's & very quiet also.

The PC P&C's & OCZ PowerStreams are designed & built to higher standards,
but that doesn't make the Seasonics bad PSU's.

I think there are many good upcoming companies such as Seasonic that may have great products, but lack the exposure...but make sure you understand how far ocz is in the game and how deep its roots are in the overclocking community not only with support but with features they put in their products.

I would stay away from the modstream series though...its like their TCC5 :p:

PerkamThe ModStreams are pretty good PSU's, it is just that aside from being modular,
there is really nothing special about them, not in the same class as PC P&C's or PowerStreams,
but for non-SLI systems they are pretty good PSU's :toast:

[STEvil]

my 600w powerstream is plenty quiet.. hasnt eaten my neo2 yet either.

[Tunage]

AFAIK, the current PowerStream 600/520 have dual PCIe molexs. :cool:

No sir.....the have dual dedicated VGA Molex's, and only one pci-e connector. I'm in between a rock and hardplace with my 600w Powerstream. It was great with the eVGA 6800Ultra AGP card I had because those use dual 4-pin molex's. But now with eVGA 6800 pci-e's in SLI that use 6-pin, they have only one 6-pin connector and one is forced to use adaptors. Love it, but selling it because of this issue alone.

i love my seasonic s12, all of the rails are right on when under load (tested with a good multimeter). they're power is rated at 40c which is nice though not as nice as pcp&c at 50c (ocz power is also i think).
