hbalija Posted June 26, 2013 Share Posted June 26, 2013 Greetings! Few yeas ago i bought Corsair TX650. It was excelent PSU for me: quiet and reliable. Then I decide to buy new rig and I gave my old rig to buddy. For new rig I bought TX650V2. It was heavy, robust PSU, better effiecency, great packaging. On first sight it was much better than first TX650. Also, it was build by Seasonic. But then problems started. This PSU had awful fan: in idle I heard clicking noise (very similar to old IBM hard disks), on lower loads fan was turning at full speed and it was very noisy. I went to reseller shop month ago, and they gave me a new TX650. I noticed that is not the same PSU. It is lighter than V2, efficiency is worst than V2, I have feeling that this PSU doesn't have the same building quality. It has one interesting feature: semifanless mode. But in this semi-fanless mode I hear coil whining. It is worst than faulty fan in V2. I must again dissasemble PSU from PC, and bring it to my reseller. Same procedure again. And then I must wait 2-3 weeks for new PSU. Who is manufacturer of new TX650? (Old TX was CWT, V2 was Seasonic). Thank you! Link to comment Share on other sites More sharing options...
peanutz94 Posted June 26, 2013 Share Posted June 26, 2013 PSU manufacturer is irrelevant. Their PSU are built to their own design despite the manufacturer. http://forum.corsair.com/v3/showpost.php?p=598153&postcount=5 http://forum.corsair.com/v3/showthread.php?t=109435&highlight=build+PSU%27s Link to comment Share on other sites More sharing options...
hbalija Posted June 27, 2013 Author Share Posted June 27, 2013 Of course that is relevant! Every company has internal QA, TQM an other quality assurance methods. I presume that if you want to produce for Corsair you mast be certified manufacturer. Certificate is a paper, the main thing is how quality assurarance tecniques are implemented in production. If manufacturer is irrelevant, why Corsair don't entrust production to e.g. Xinhang? Link to comment Share on other sites More sharing options...
geronimo427 Posted June 27, 2013 Share Posted June 27, 2013 Does Xinhang have the requisite manufacturing facilities, technical expertise to consistently meet the specification guidelines, devoid of local and central government red tape, etc..? Of course the manufacturer is relevant, but it's more relevant to the buyer that he is issued a valid warranty for his product, which Corsair honors. The buyer should be more aware of a manufacturer's product reputation, than their production network. Link to comment Share on other sites More sharing options...
hbalija Posted June 27, 2013 Author Share Posted June 27, 2013 Reputation? At this moment Corsair has not so good reputation to me. I bought 3 PSUs, two of them was faulty. One had faulty fan, this one has coil whining. OK, I hope that next PSU will be good. But main question remains... Who is manufacturer of TX650 "V3"? Thanks Link to comment Share on other sites More sharing options...
zomgtruth Posted June 27, 2013 Share Posted June 27, 2013 Not too long ago Corsair revamped nearly the whole line of its PSU's,many with the same names as their predecessor's even if the OEM/platform was different. The easiest way I have been able to keep up with the changes made is to consult this list of Corsair PSU reviews. Its got a list of all units(current and discontinued)/oems. http://www.realhardtechx.com/index_archivos/Page447.htm tl;dr "v3" tx650 is a cwt sourced unit. v2 is discontinued but there is still the Seasonic variant ond one other rebadged unit based on the same platform out there.

peanutz94 Posted June 28, 2013 Share Posted June 28, 2013 v2 is discontinued but there is still the Seasonic variant ond one other rebadged unit based on the same platform out there. zmog, that is partially true. Corsair has stated many times that their PSU's are not just rebranded units. But built to their own specs and design . Please see RG's response in the link i posted earlier.

Why did you buy a Corsair, instead of an Athena power supply? Both could have been manufactured in the same facility. Corsair, like any other top tier manufacturer, remains in business because of their reputation( Marketing 101, Manufacturing 101, Engineering 101, etc.). Common sense says that if you buy a product and you are not satisfied, you look elsewhere, rather than demand a full disclosure of a company's superstructure.

But built to their own specs and design . Please see RG's response in the link i posted earlier. I never said they were,I don't even see how you got that impression from what I said. But IMO a psu built on the same platform by the same OEM as Corsairs unit is just as safe a bet. But since you brought up rebranding and the claims of custom specs and design I thought Id point out this easy example of how different or not the units are. The tx650v2 is based on the Seasonic SS650AT,do a google image search for both and compare the layout,capacitors, etc and decide for yourself just how different they are. As I said earlier there is another variant of this unit in the wild as well. Link to comment Share on other sites More sharing options...
geronimo427 Posted June 28, 2013 Share Posted June 28, 2013 Both unit layouts appear to be similar, probably due to some cross licensing agreements, since both were assembled at a Seasonic facility. If you read the electrical spec's, you'll find one to be patently(specifications) a Seasonic power supply, and the other a patently(specifications) Corsair power supply.

zomgtruth Posted June 29, 2013 Share Posted June 29, 2013 And they perform exactly the same huh? http://www.plugloadsolutions.com/psu_reports/SEA%20SONIC%20ELECTRONICS_SS-650AT_ECOS%202233.1_650W_Report.pdf http://www.plugloadsolutions.com/psu_reports/CORSAIR_CMPSU-650TXV2_ECOS%202233_650W_Report.pdf Sorry to burst your bubble,but they perform exactly the same, based on the same platform, same Caps,... If you still think its coincidence Ive got a bridge for sale at a great price.. Link to comment Share on other sites More sharing options...
geronimo427 Posted June 29, 2013 Share Posted June 29, 2013 At what institution were you educated(or uneducated) with technical skills to interpret electrical specifications? Are you aware of patent laws? Here is a simplified version of their spec's, that hopefully you can understand. SEASONIC: +3.3V: 24A +5V: 24A +12V1: 48A +5VSB: 2.5A -12V: 0.8A efficiency 87% 80 PLUS BRONZE CORSAIR: +3.3V: 24A +5V: 30A +12V1: 52A +5VSB: 3.0A -12V: 0.8A efficiency: 20% (Light): 83.21% 50% (Typical): 85.13% 100% (Full): 81.28% 80 PLUS Link to comment Share on other sites More sharing options...
zomgtruth Posted June 29, 2013 Share Posted June 29, 2013 patent laws? what are you on? I dont care what it says they are on paper. my point is/was that even with slight variances on the platform they perform identically,have many of the exact same components and layout.

Ive reserved judgement on the Chicony(hipro) units because I havent seen enough about them but from what I can tell Hipro isnt a stellar PSU builder either.
