Back in stock.

I don't know anything about this specific model, but seems like a great price. I have a Seasonic I got 6 years ago and it's still running strong.

It's a new series meant for people who want quality components but on a "smaller budget".

I'd probably jump on this (or the 650W if it went on sale) if I haven't bought the X750 earlier.


[edit] I wish Seasonic (or all manufacturers) shorten the length between each SATA plug...

Ridiculous to advertise it as SLI ready with a wattage that low.

This should be able to run 560ti's in sli... A complete system on full load with a pair of 560ti's only use 450 watt on load. And this is a quality psu too. People overestimate WAAY too much on the wattage they need for rigs these days..

Pretty much.

CF 7950s would be fine. [legitreviews.com]
SLI 660 Tis would also be fine. [xbitlabs.com]

I should specify. I'm not saying that you should, I'm saying that you can. A solid 650W unit is plenty for SLI/CF anything though.

I mean a pair of 6770s or 550tis should be fine, but considering this is a quality psu I would say it's pretty safe to run 560's unless you're doing massive ocing.

:lol:

Shows how much you know. A good quality 500-600w psu, can easily sli/crossfire two low/mid end cards.

Good deal.

So, realistically, for this build...

- i7 3770K / Z77
- Noctua NH-D14 Cooler
- 4x 7200 RPM HDD (RAID10)
- 2x SSD 128 GB
- 1x BD-R
- 1x BD-ROM
- 4x 120mm Fans
- 1x 200mm Fan
- Possible GTX 570 / GTX 670 in the future

Is this enough?

I've been leaning towards a Seasonic X650 or X750 for a while (especially with the recent deals) but if there's no need to go for that much power...

Yes, more than enough.

This I have a corsair 550w crossfire ready but it can't do it on most the cards.

I used a Kill O Watt meter this week to test my rig. I pull 252 watts when I run Prime and FurMark. I am selling my SeaSonic X750 and switched to a Antec High Current Gamer 400w. However I was eyeing up this SeaSonic 550 today. Modular and Gold Rating.

My system:
i7-2600K OC'ed to 4.0GHz
EVGA GeForce GTX 650
2x8GB 1866 DDR3
Ceton DVR
128GB SSD for OS
120GB SSD for Recorded TV and Commerical Skipping
WD Black 2TB HDD
WD Green 2TB HDD
WD Green 1TB HDD
SATA BluRay Drive
6 Case Fans (Antec Two Hundred Case)

You're completely right. It would also be completely safe to run the cards I linked as well in most builds. You should have a bit of room over 550W to play with on a PSU like this.

But bro, I need to fill up every fan slot with a $2 fan.


:lmao:

Maybe some people here think you need 1000W for SLI...

Some people are just suckers for marketing =P.

http://www.guru3d.com/articles_pa...ew,14.html



You were saying?

Did you even check the test system specs?

If you can afford that kinda rig, the price of the power supply is probably the least of your worries. Anything not built balls-to-the-walls will run fine on a 550w.

Yup. The only people who really need 1000W PSUs are the ones running fully internal water cooling pumps and tri SLI.

You didn't answer anything. You can still sli/crossfire two low/mid-end cards with this unit.

You can find plenty of people online, powering two 670's alongside an ivy/sandybridge rig,
with a good 650w psu. It's only an issue if your cpu is a nuclear reactor, otherwise this is
an sli capable power supply. (Key word, two low/mid end cards).

Kill-a-watt is glorious.
Exactly. That test system, is a lot more power hungry than let's say, an ivy bridge rig.

Can I run 2x 6950's on 550watt corsair?

I find modular psu's to be a gimmick because I end up using all of the plugs anyways.. Just throwing this out there. Otherwise this is a solid psu. Will easily run any single card configuration.

I see that people are saying that it will run xfire and sli configs, but i don't like the idea that your rig is sucking 90% of max power. Plus psu's degrade over time so it might not handle the load in 2-3 years. imo I would go with a good 600 - 700w psu for multi gpu's

wow this is good deal but i already have that 750w seasonic from last deal. should i return it and get this to save 50 bucks?

It is very close, if you are running a high OC on your CPU and the, 6950s have unlocked shaders to 6970s with or without OC then NO. You would need a good 650W supply. When i Stress my Cpu ( 3930k @4.6ghz to 100% ) and both 6950s that are unlocked and OCd to 940/1420 to 100% my wattage at the socket is 700W. I also have 2 1tb drives in raid 0 and two SSD drives in Raid 0 Plus 4 fans ( Gt AP-15s ) and one waterpump ( mcp-655 ). If you have a high end cpu then i would go for the Seasonic x750 because you never want to stress your PSU to 100% all the time.

depends on your rig. if you oc stuff and have 2 or more gpu. I would just keep it and save the hassle of returning.

True. Then again, gpu's are becoming more and more power efficient by the year.

This power supply is perfect for single card configured rigs, and more than enough for most.

current gen gpus and cpus use way less power than past gen gpus... 600 series much more efficient than 500 series!

OOS already

I'd like to test my rig to see what kind of power I'm currently drawing under load. Kill-O-Watt seems to be a physical device though...

Are there any software-based ways to find this info?

Maybe you should have left in:
Yes, cold cathode lights in the testbed. This wasn't listed in the part about test equipment, nor what kind of water-cooling was used, nothing about drives...so lord only knows.

It also says:
So it would seem that full stress number is for the 2-way SLI since the 298s match up...but that would mean their system (which they already said "On average we are using roughly 50 to 100 Watts more than a standard PC") was using 449W...but then they say a second card uses 175W more....so is that saying that one card would use 449 - 175 = 274W? That can't be right. Is it just too late for me to think or does that article make no sense?

only guesstimates

Power Supply Calculator - extreme.outervision.com/PSUEngine

You'd need a case with a lot of fan slots to make much difference. Most of the 12cm fans I see now are between 0.12A and 0.4A draw, so like 1.5W to 5W per.
I'm not saying you can't find some x38mm Deltas using 20W+, but for the most part they're generally under 5W. :P

Iackluster... considering just last week for $25 you could snatch a SeaSonic 520W - rebranded Antec Eco 520c

~S

the question to ask yourself, is going modular and the extra 30w with Gold rating worth the extra $35

If you have the #1 single GPU setups, this'll be more than enough. Steal.

out of stock

Appreciate the reply!

Lol--exactly what I'm looking for and I missed it. CURSE YOU COMCAST DOWNAGE.

Just to update, this is available in stock again at Neweggs for the same price.

$59.99 + Free Shipping After Rebate

Thanks for posting, good PSU and price...confirming it is in stock again (at least for now)...

TU

One note about this from a review I read earlier today... it sounds like the fan is always on, unlike the X series where it remains off up to a certain load.

It sounded as though it's very quiet so I don't think noise is a factor, but it's worth mentioning.

Glad it came back. in 4 1 since it's the best deal ATM. I'd go for the rebadged 520W mentioned earlier if I would but I need a new PSU today. 3rd time replacing one in my Dell 530. Dell (350W w/ HD2600), Antec 500W w HD2600) and lastly CoolMax 500W w/ HD5770 all had their shots in the last 5 years. in the last 2 cases, it was the fan that died and allowed the power supply to overheat.Once they overheat, I'd just as soon get a new one than replace the fan. Not too sure about modular. The Antec was modular and it didn't last but 14 months. Anyways, hoping to get the promised like out of this one.

How do you only pull ~250w with that setup at full load? That seems incredibly low. Most similar setups I have seen pull around 320w. That's impressive if accurate. I pull about 550w under load in the same scenario on the system in my sig.

that GTX 650 is about 50 watts max

Now that I think about it, that's true. I am basing that on a 550ti. It is impressive how much more efficient it is than that.

Can anyone comment on G Series vs M12 II vs the PC Power and Cooling rebadges (which as I understand it are built by Seasonic)?


My current build.. ASUS Maximus Gene V Micro-ATX, overclocked i7-3770k (with Noctua NH-L12), 32GB of RAM in a Lian-LI PC-V355B was a little tight... mostly because I'm not using a modular PSU.


I generally shoot for total silence / power efficiency in my builds, and have been using Seasonic for years (so had simply carried over an older non-modular Seasonic PSU to this machine). I don't play games and use on-board video, so the wattage here is totally fine.

I'm an amateur photographer and a software developer (who ends up running a bunch of VMs), in case you were wondering why I need the CPU / RAM ;0

Anyway... I'm a little out of touch with the current Seasonic line if anyone has a good link to the differences.

There is a slientpcreview on the G360 here that I'm taking a look at -- http://www.silentpcreview.com/Seasonic_G360

Compared to this, which would you guys pick?

http://www.newegg.com/Product/Pro...6817139005

I switched from a GTX 460 because it uses way less power. Its mainly a HTPC but I do some light gaming every once in awhile. Borderlands 2 plays at max settings.

I am sure it might spike towards 275w if I was transferring files, gaming and running prime. I am only switching from the Antec HCG-400w to get the 80 Gold and modular cables.

Awesome back in stock.

Gonna be great for my budget build.

Will this be sufficient enough to handle an OC'd 7970? If it's cutting it close then I will just go with that Antec 620w or the Corsair 650w

Can anyone comment on the quality of this? There doesn't seem to be a lot of ratings available.

Found this review on the unit:

http://www.techpowerup.com/review...550/1.html

Yes, this will provide more than enough power.

More than enough? Awesome, that's what I was hoping for. Thanks for the answer. Well hopefully I don't regret buying this PSU so close to BF...

Any of you know how many Watts a USB 2.0 draws? Or USB 3.0?

I'm seeing .5 Watts for USB 2.0---and conflicting info for 3.0

Thanks.

Not enough for it to matter.

Trying to analyze various tests specifically for ripple to figure out the most stable and precise power supply between this one and the X-750. This is for a home audio server so lowest ripple on all rails is most important for me and not the power rating as I don't need what the 750 dishes out. Can anyone see any differences between the X-750 and this PS? The only area I see is higher ripple activitiy on the main 12V and a little higher on the smaller 5V/3V rails. I'm trying to translate this into real world audible sound differences.

Thoughts here?

This just dropped another $5 today, so it's $55 AR.

Great deal!
