Corsiar 650TX

[Roadhog32901]

I have read the reviews on the Corsiar VX550 (may end up with) and 750TX (which is a little expensive and maybe a little over kill even for upgrades down the road...

I do not see a review here on the 650TX? Do you guys consider this a good power supply...as good as the VX550 abd 750TX??

Can some one tell me if the Corsair 650TX is CWT made like the two mentioned above..if there are any review links available...and what you think of th 650TX.

The VX550 for be fine for me at the moment...but I am thinking of upgrades down the line.

The best deal I can find on the Corsair power supplies are at www.buy.com...any one find a site with better prices??

Thanks

TX650 is a Seasonic build. Review (http://www.silentpcreview.com/article813-page1.html).
You can pick any Corsair PSU. All are very good PSU's.

On that review...

3. AC RIPPLE refers to unwanted "noise" artifacts in the DC output of a switching power supply. It's usually very high in frequency (in the order of kilohertz or megahertz). The peak-to-peak value is measured. The ATX12V Guide allows up to 120mV (peak-to-peak) of AC ripple on the +12V line and 50mV on the +5V and +3.3V lines. Ripple stayed very low, under 15mv on all lines, until about the 200W output level. Beyond this point, it increased in direct proportion to power putput, and reached a fairly high 94 mV on the 12V line at full load. This is still less than the maximum 120 mV ripple recommended by ATX12V. The higher than expected ripple may be related to our sample's thermal behavior.

Is this something one should worry about...it seems a little high?? Even though it is in spec as the review says?

[Oklahoma Wolf]

If it's in spec, there's nothing to worry about. That's why there's a spec.

The noise in the MHz regime is not really relevant as the strength of the harmonic noise drops with frequency (given that switching noise is predominant).

You are talking over my head...and looking at these power supplies for the last two days makes my head feel like it is going to explode.

I first became concerned about ripple when looking at another brand power supply...check out the 3rd post down...on the below link...very short post...

What concerns me is what the guy said about over clocking...both the cpu and gpu...as the ripple may hold back a decent over clock...and of course..the other items in post 3..here is the linky:

http://bensbargains.net/forum/viewtopic.php?p=16638&sid=fd89db8e3618d2afd23d4ee11c240f53

What I am sort of taken back by...is the 650 Corsair appears to be made by Seasonic..which I thought to be up there with the best.(I am not into power supplies like you guys...but even I have heard about Seasonic)..but the 550 and 750 are made by CWT according to reviews here...and to be honest...going by only the reviews...the 550 and 750 seem to be of the cleanest power...and I can find nothing...any where...negative about that 550..and am sort of leaning that way...

I had never heard of CWT before two days ago...but this is the first reading I have done on power supplies in 4-5 years...my old Antec 430 (which I think is a Seasonic) is still going...but getting sort of old.

I am still reading on this...and find it sort of interesting...but a little mind numbing all at the same time..

[MrWicked1968]

in the thread you linked to, they were talking about FSP-built OCZ PSU's. what relevance is that to a Seasonic- or CWT- built Corsair?

Your old antec 430 is most likely a CWT build (unless it's an EA430) filled with problematic caps.

It doesn't matter which Corsair branded PSU you pick, you will be getting a very well made unit. Corsair sets the standard for internal components and Seasonic and CWT build to that standard. That's quite different than OCZ telling FSP to push out a 700w unit as cheaply as possible.

Sorry. :)

If you are not doing tri-SLI the Corsair HX620 or the VX550 would suffice for a home computer, i.e single physical CPU, 4 HDDs, SLI GFX cards.

Now among all of Corsairs products for your application, the CWT built units have higher ripple when compared to the Seasonic built ones, but not by much and well within ATX spec. Bottom line. Ripple is a non-issue.

The CWT units regulate a bit better than the Seasonic units. Again, te difference is negligible. Bottom line:- Regulation concerns are a non-issue.

If I had a choice, I would go with the CWT built units as they are more affordable and I prefer their independent regulation design.

[treshix]

I tend to go with the Seasonics because I like the feel of them better.

i.e. the differences between a CWT and a Seasonic build basically come down to personal preference.

94mV at 100% load is really rather good. in either case, are you actually going to fully load the PSU? Very doubtful. As a matter of fact, your efficiency "sweet spot" on a PSU is usually 50% load _anyway_.

And if you've got a component that can't handle 94mV ripple, then that component wasn't build to be able to handle ATX spec which is a completely different problem. :)

[spursindonesia]

Corsair sets the standard for internal components and Seasonic and CWT build to that standard. That's quite different than OCZ telling FSP to push out a 700w unit as cheaply as possible.

Now, you hit the nail right on its top, mate, bull$ eye. :)

[Roadhog32901]

MrWicked..Reason for the link (about OCZ) is it mentioned ripple and its effect on ability to overclock.

Supernade..no...I doubt I will ever go tri-sli...but may go (2) 8800GT's....

Question...what p/w would you guys buy if running (2) 8800GT's, an overclocked Wolfdale E8400/E8500, 4 hard drives, 4 optical burners...you guys think the Corsair 550 would pull it?

This morning I see the rebates are no longer available on buy.com. I did not order yesterday as I was still trying to decide...and also because I figured buy.com would not have shipped it out that day. I order from the egg most times and notice my invoice date is usually dated the day after I order (which would make the rebates invalid). With rebates....they seem to find any reason not to pay.

If you guys know of any deals please post...thanks for your help ...hope they post some rebates...or find a better deal some where else.

I will just have to keep checking www.buy.com and

That 550W would suffice, but if you are going to add more drives or replace the four optical drives with hard drives, then I'd go with the HX620 or TX750.

Some people will say that all you ever need is a 200 picoW unit, but that is based solely on AC power consumption numbers (which is something not entirely accurate).

[Roadhog32901]

The HX620 is a little on the expensive side...and more then I want to spend. Pricing it out..the TX750 would be cheaper...the main difference in the HX series is just the modular option correct?

Any one know of www.buy.com trends?? They took the rebates down....but did not put any more back up? I saw an old post while searching...and a few months back they had the 550 for $60 including all rebates...so are prices in general going up or down??

Any one know much about buy.com...I am wondering as even when I have ordered with them in the past...I never saw a contact phone number on their site..nor invoice (if I remember correctly). Do they have their own warehouse...or do they farm orders out to other vendors??

Attention:Wolf
That TX650..still thinking about that one...in the review the person states that the ripple was more then they were used to seeing in Corsair power supplies..even though in spec...they even hinted that maybe it was just that unit?? Ripple is not good it seems...even though it is in spec (as you point out)...if picking between two power supplies...and most specs are pretty much equal except ripple...I think any one would pick the one with less ripple..correct.

[Oklahoma Wolf]

I think any one would pick the one with less ripple..correct.

I would, but only if I was absolutely certain build quality is the same. I've had a few units pass through my hands already that outperformed the CWT PUC engineering sample in my main rig on ripple, but none I've actually wanted to keep as a replacement.

[Super Nade]

I tend to look more at regulation than at ripple. As long as it is less than about 60-65% of the ATX spec at full load, I'm happy. I suspect this is why Wolf likes his CWT ES so much. ;)

Ahhh...sounds like "The Wolf" prefers CWT over Seasonic:D


Any one have info on www.buy.com as far as trends (rebates) and if they have their own warehouse/contact number?

[Oklahoma Wolf]

Show me the Seasonic that can do 100A combined on the 12V rails, and I'll consider it :p

So I assume out of the 550, 650, 750...you would choose the 550 or 750.

decisions....decisions

Seems like you are a CWT fan...what other p/s do they make that may be worth looking at?? Well...for my specs any way?

[Oklahoma Wolf]

Why assume I'd even buy Corsair at all? I have a BFG ES-800 review sample sitting here I prefer to the whole lot - Andyson built :D

I "assumed"..given those three choices..you would pick the 550 or 750 because they are CWT made...so I will not assume..ot of those three the 550, 650, 750, which one would you choose..

I will look into that BFG ES800..to see if it is in my budget...

I guess one question I also need to ask...it seems if you have an ES sample..you must be a tester.(there I go again..assuming)..what brand/model is most consistent in all areas of performance?

*Edit: Checked price...way too expensive for my poor buget.

None of the above - they're not modular. Of the modular, HX620. If I had to pick a non modular one, TX650. I hate the loose heatsink screw thing in the CWT models - it would drive me nuts, no matter how small the chances of them working loose are.

I guess one question I also need to ask...it seems if you have an ES sample..you must be a tester.(there I go again..assuming)..what brand/model is most consistent in all areas of performance?I'm currently doing all the PSU reviews for this website. ES-800 review is planned for later in June :D

Most consistent? Zippy.

Wolf..for some reason I did not put the review and your name together..I see "you da' man" I like the comedy with who ever writes the reviews (beavers and such..nice touch).

The zippy is out of my price range..but looks real nice. I have a $100 for a p/s and that is stretching it. I have to answer to a higher power (the wife).

Question...on that review on the 650...what is the chance the ripple is only to that certain unit being tested. I notice you guys have not reviewed the 650...just wondering why you would say that one...unless you have done some testing with that unit? Are you just going by seasonic quality in general? And...is ripple..as a general rule...more on the seasonic or cwt...(just as a general rule wolf).

Is there another p/s I should consider...you know what I am looking for spec wise...and I have about $100 for the p/s which I would consider max...I may find a better deal on another unit if you can give me a few brands/models. I know $100 is not much these days...but it is to me...

Thank you

Pretty low. But, like I said before - in spec is nothing to worry about.

[D3vastator]

CWT has better voltage regulation.
Seasonic has better voltage regulation.

Actually, 650W is overkill for general rig.
