Corsair TX650,first post...

[nasah]

Hi all ,first post here.

I m reading all reviews here and the review sites before deciding to buy corsair tx650.In fact i planned to buy long time ago but after reading reviews i really confused about the ripple problem with this unit.Maybe if Jonny could test it ,i might choose more easily.

I have to be more clear about what I m really thinking,even i m a fan of seasonic products,i can say that this is not good as we used to see the other seasonic builts if they produce a bad product but why nobody say anything negative about the tx650,is it really good with its high ripple or the reason is everybody loves corsair with its mistakes?

Note,sorry for my bad english.

Thanks for all answers.

There's no high ripple problem. The TX650 is well within the ATX spec for ripple/noise.

Where did you see the issue with a "ripple problem"?

[Smirnoff]

According to SPCR, the ripple is 94 mV @ 100% load. They did however point out that heat could be the cause of it. (The exhaust temp hit a beefy 72C). But ripple was still within spec, and you'd never run a PSU at max. load anyway.

SPCR's ripple ratings are suspect. They also said the Zalman ZM850-HP had out of spec ripple.

Thx for answers,i saw the high ripple problem at SPCR.In fact it s not a big problem if its under 120mv but u know there r lots of brand that they can stay under 50mv.So thinking about a near 94mv is making hard to decide tx650 or other brands.In addition,i can buy 750 but i never liked cwt.I read about it here and it has ripple like 70mv,I know it s under specs but enermax,be quiet,silverstone have units like this and they have so low ripples.You can say that i should go and buy one of them but lets say i had different problems with them.

I know its hard to reach max load but if this is a heat problem why didn t retest unit,or all tx650s are working above 70c?And in addition to heat you all say u cannot max load it but we r judging all other brands if they have ripple where is above 70-80s...Then we can say for all brands if they r not passing 120mvs,they r all perfect power supplies,am i true?Because of no unit can reach max load,true?

I said in my first post too,i always like to use seasonic ,but i used lots of brands and if we r comparing the units then we all have to be objective,i asked for an opinion that should i buy tx650 or look around another one with a quality which tx650 has without ripple near 90mv?

Last thing,nobody said your wellcome,i m so sry for it...

ı reread the SPCR review and think i should bring some of them here to discuss.I hope and want to believe that there is a problem with the test unit beacuse of this section at the review:



7. TEMPERATURE & COOLING

Our sample reached considerably higher temperatures than usually encountered, starting at around the 200W mark, where the temperature rise through the unit reached 15°C. With a majority of quiet PSUs that have been tested on the same platform, the temperature rise at this level tends to be around 10°C. The Corsair VX450W and the Seasonic S12II-380, for examples, both had a temp rise of 11°C at this load. Both intake and exhaust temperatures rose a bit faster and higher than in most other PSUs. The exhaust air temperature exeeded 50°C at just 250W and rose to over 70°C after about 15 minutes at continuous full load. This seems a bit too hot for comfort, although nothing untoward occurred; the only related "misbehavior" was the somewhat higher than normal ripple at full power. Admittedly the chance of a desktop PC actually demanding 650W sustained power for any length of time other than a momentary peak (with the most excessively power-hungry components) is extremely remote.


Is it normal for this unit to reach 50 c at 250w and then 70c?Can be aproblem there?
Thx for answers.

The TX650 is 80Plus certified (meaning that from 130W to 650W output it's over 80% efficient). At 250W and 80% efficiency, we're talking 50W of heat output.

That 50W has to go somewhere. The fan in the TX650 is designed for silence, and all the internal capacitors are upgraded to 105C in order to further the warranty at higher heat levels (which they will be reaching due to the quieter, lower airflow fan).

While there may be other PSUs that can put out less heat at that 250W output, you would trade off noise levels of the fan or other cooling design issues.

The TX650 is, in my opinion, one of the best 650W units on the market, and certainly the best one for the price right now. But then again, everybody would tell you that.

If the review at SPCR bothers you, by all means, do not purchase the PSU and purchase something you are more comfortable with. I wouldn't want you to buy our products if you felt uneasy.

But be aware we do offer one of the best warranties in the industry and our customer service and support is very easy to contact should you ever need any assistance.

When measuring ripple&noise, an electrolytic(10uF) and a ceramic capacitor should be connected to the probe head. If SPCR forgot them, they'll get wrong ripple readings, I suspect.

Thx for all answers Redbeard,I bought the unit this morning and have to say that its really nice for now.Hope that it can live long time.In fact i was afrading of the electrical noise(its like tisssssss,or like zzzzzz) like lots of silverstones had,but now i can say it s so silent for now.Again hope that the ripple can be minimal for its class.Thx again all answers friends.

Agreed, I am a very logical person and my comparative analysis came to the same conclusion: The TX650 !

Not only is it the product "Best in Category", it is backed by Corsair's legendary support and and longest warranty in the business. Have you ever tried to contact Antec or any of those other PSU brands ? No live person to speak to, emails that never get answered and the list goes on to give you frustrations !

Since Corsair has retail presence and price comparable to most of those PSU brands, its a no brainer !, if Seasonic were more available than it would be a slightly different story. Hey, if I can't readily find a Seasonic PSU in a major metropolis like where I am, the marketing guys over at Seasonic USA ain't doing their jobs very well. When I found out that certain Coraisr models were made by Seasonic and readily available locally, I picked one up and it is a "pleasure" to have in my system "Customer's Enlightenment" !

Just to assert my personal opinion once more, I've had my HX620W for well over a year, and seeing as it's related to the TX650W (but with modular cables), I have no complaints about it. I'd get the TX650 in a heartbeat if I ever needed a PSU in the same class. I do share the same concerns about the SPCR review as well.
