Seasonic S12 600W or OCZ PowerStream 520W PSU?

Which is better, or is this comparison a wash, as both are great PSU's?

Going to be paired with A8N32-SLI, Opteron 170, and G Skill Extreme 2GB DDR 500 memory, and X1900XTX video card.
 
Well i'd go for the seasonic myself, but since low noise isn't really a factor it's a bit of a tossup.

They are both good PSUs, the OCZ is modular, the seasonic has very high efficency and low noise.

Teh OCZ powerstream is not modular.
 
Hands down the S12. If you must have gamers bling the OCZ is decent, thier OEM is
Topower but soon to be FSP Group. If modular is a must and your willing to wait a bit,
the new *M*12 Seasonics will be out soon. It's main harness will be hardwired.
The S12s might drop in price a bit when the M's hit the market but I doubt the drop will be much.

Ah, whoops! 🙂

Still not a bad PSU, but if the prices are equal then i'd just go for the seasonic then.

No problem, the Modstream is the one that is modular. Regardless, they are not equal in price. The seasonic (600w) is SLIGHTLY more expensive, about 20 bucks. Is the 600W Seasonic worth 20 more than the 520W OCZ Powerstream?

I would imagine so.
 
If you need that much power then it's worth it, odds are that you don't. (Do you have a SLI system or crossfire? If not then you don't need the 600W model 99% of the time.)

not willing to wait, and don't really care about gamers bling or modular. I think I will spring for the S12 600W, but I've heard horror stories about their support.

I'm really not sure but iirc there was some issue when Seasonic was hooked-up to some
DFI boards. Maybe they got tired of dealing with a board issue.
I don't care much for rebranded PSUs. I have 1-Fortron, 2-Zippy/Emacs and 1-Enhance here.
Seasonic designs, builds and tests in-house, they stand behind thier product well.

NOTE: Before buying any rebrand I'd want to know the OEM 😉

I'll go with the S12 600W. 🙂
 
I've been very happy w/ my S12 600 and 2 S12 430's 🙂 they power the 3 pc's they are in w/ no issues almost silently 🙂
 
I have Seasonic S12 600W, no problems. I'd recommend that over OCZ. Before you can hear the psu's noise, you must get rid of case cooling, hard drives, cpu and gfx card fans noise 😛

Yea, there are some confirmed compatibility issues with Seasonics and DFI NF4 boards.

 
got my S12 600w last week and don't have any issues with it. upgraded from an Antec SP2.0 500w because i wanted something quieter. hasn't disapointed me yet. cable lengths aren't an issue with my P180 case and A8N32 mobo.

PS the guys at SVC told me there were 2 versions of the S12 600w. the old one with a cable management system you do yourself and a new one that's sleeved. i ended up with the sleeved version.

Final Words...

OCZ has done an exceptional work with their line of PowerStream power supplies. It is amazing to see how a niche memory manufacturer is extending its product line to make something that is above and beyond the reach of various power supply manufacturers. OCZ's goal to stay ahead in the enthusiast community is realistic and it shows us the amount of effort OCZ is putting into researching products that can truly be labeled as enthusiast-ready.

The physical looks of the power supply are amazing to say the least. The reflective surface of the power supply will surely match with the elegant appeal of the case. This should be the power supply for modders who are looking to make their computer cases stand out from the rest of the crowd.

We are certainly impressed with the performance and the stability that PowerStream line of power supplies have to offer. What is really exceptional about this product is that OCZ included their power leads to ensure the maximum stability and proper flow of current to your PC components. Not to mention the fact that this power supply is based around OCZ's ConnectAll upgradibility factor. This means that you can purchase this power supply and install it in any form factor PC to make it work. This also gives a return of investment for the future with the upcoming BTX standard from Intel.

The accessories, as always, are just as thorough and appreciated as the rest of the product. However, we would like to point out that OCZ has not sleeved the power supply. Even though it is not a difficult task for the home user, it would've certainly added to the overall value of the product if OCZ had kept this in tact. We are unsure as to why OCZ did not keep wire mangement in their plans when designing the power supply, but it would be advisable for OCZ to keep wire management in mind for their upcoming power supply design.

The second thing on our list of discussions is the price of this power supply. At various online retailers, we found the PowerStream power supply unit (520W variation) to be around $130.00. When we compared the similarly rated Antec TruPower 550W unit, we found it be around $115.00 at numerous online retailers. Although there is around a 13 percent price difference between the two, we think the price is justifiable. Antec does not have enthusiast features that OCZ offers in their PowerStream line of power supplies.

If you are looking for an all rounder power supply that assures future upgradbility and ensures the return of investment, we strongly suggest that you put OCZ's PowerStream power supply unit at the top of your list.

Final Words
Seasonic S12 600watt

Amidst all the reviews of flashy items with power and style at the forefront of their design, it can often be the case that a Plain Jane decent performer is overlooked. While the appearance of the Seasonic S12-600 isn?t going to win it any awards, its features and performance certainly will. 80% efficiency is not a common thing from the majority of PSU?s in the market place today, and neither is a 600w power rating. Couple that with support for all the latest technology and form factors, as well as quiet operation and you have a very nice unit indeed.

There are a couple of items that I think should be changed however. With a 600w power rating, it?s hardly lacking in power, so it would have been nice to have more than 6 Molex connectors. I don?t think most folks will run out, due to the fact that the Seasonic S12-600 does have 4 SATA and 2 PCIe VGA connectors on hand. Speaking of the SATA connectors, I would have liked to have seen Seasonic use 4 side facing SATA connectors rather than 2 side facing and 2 flat/front facing. I did find the packaging a little misleading in regards to fan control, but you can have 2 low speed 5v 3pin fans powered as well as third at full speed 12v.

Power and features aside, the Seasonic S12-600 comes with the standard power cable as you would expect, and also supplied is a Dr. Cable cable tidying kit. This kit isn?t anything special, but it does go a long way to tidying up your cabling and is a lot more than most PSU?s packages supply.

A quiet runner too, the Seasonic certainly has a lot going for it in regards to power output and features, and you get a feeling of quality and solidness from it that is very reassuring. Designer PC users will probably want to look elsewhere, but power hungry system users should certainly take a good look at the Seasonic S12-600. It is a little expensive in comparison with most of the competition however, but as the old saying goes, you get what you pay for.

Bottom Line: An all round decent unit, power hungry system users will certainly find the Seasonic S12-600 provides enough juice to get the job done. You will have to pay a little extra for it, but it is quality, quiet and has quite a good package

*****************************************************

Take your pick I bet you would be happy with iether one of those PSU`s!!!

Good Luck!!
 
in custom pc's psu reviews a few months back the seasonics was tops even at 100% load. still cool, still efficient, still quiet. thats quality. unlike other psu's it doesn't ramp up its fan in an insane way. it doesn't need to. seemed like a pretty good review, they had the psu's tested at 50/75/100% load. testing efficiency heat and noise at each level. some failed competely at 100%, others just became grossly inefficient.
 
Either one is a good choice. If you can find one cheaper than the other by more than $20, I'd go with that one instead. I wouldn't be surprised if PowerStream is stronger than the 600 Watt seasonic despite its rating since it has a solid 33A rail vs. dual rails which proves to be better for overclocking. It also has a 5 years warranty and adjustable pot rails. VGA and HDD cables are insulated for cleaner signals. If you don't get Ver 3.0 of the Seasonic, it'll be louder than the OCZ.


 
I've had an S12-600 for almost a year now. I'd purchase another for a new system in a heartbeat. No problems whatsoever, and it's VERY quiet.
