Corsair TX vs. OCZ ZT 550Wby Martin Kaffei on March 26, 2012 9:30 AM EST

Corsair TX550M Internal Design and Fan
Corsair uses a 140mm fan from Ong Hua with a ball bearing. The product number is HA1425H12B-Z and it takes 0.50A. A Sanyo Denki fan would be better but the price could be a problem and Sanyo Denki is still a reason to buy the more expensive Corsair AX. Opening the unit clearly reveals that Channel Well is the ODM. Transient filtering starts behind the AC inlet and continues on the mainboard. Like nearly all modern PSUs, the TX550M has active PFC. All transistors have very common ratings so there is nothing special needed to reach 80 Plus Bronze.Most capacitors come from Nippon Chemi-Con and there are some all solid ones in the secondary circuit, but the KY models are a usual choice for high-end PSUs. It would be nice to see some other brands or types; however, all parts are high-quality. The only point of criticism is that the fan connector could be glued down, but that's a minor issue at best.

Unless the yellow is just meant to show there is a difference. But it seams in the rest of the areas the better supply is highlighted.
Both supplies look pretty good though, even if priced a bit higher than some similar supplies.
Martin Kaffei - Monday, March 26, 2012 - linkSounds more correct, right.
Thanks a lot.
lyeoh - Monday, March 26, 2012 - linkHas Corsair really improved their quality since: http://www.behardware.com/articles/843-3/component...
FWIW, OCZ and Corsair's nonPSU stuff seem to get returned quite often too:
Both these PSUs might be OK, but why should I care? There are other manufacturers who have a better track record when it comes to quality. Poor quality in a range of similar models is understandable, but poor quality in different types/classes of products just tells me to avoid buying anything from them.
I'd prefer to see more reviews of products from manufacturers that care about quality. Who the heck wants to read reviews of food from restaurants that have a long track record of giving a significant percentage of their customers food poisoning? I don't care how good their food looks.
Are these even significantly cheaper?
Samus - Tuesday, March 27, 2012 - linkMy advice to you is stop reading BEHardware.
Those statistics for every segment they 'measured' are a joke. Just drafting such a distasteful article is a huge lapse in journalism judgement on their part. Nobody in their right mind would gauge component reliability based on return rates over a 6-month period from a single source.
The only way to measure reliability is by reviewing the initial quality in detail and putting the components into real-world scenarios to report any abnormalities over time. AnandTech and other legitimate hardware review sites do this, as does Car & Driver, Consumer Reports, Home Theater Review, Gun Directory, etc
seanleeforever - Tuesday, March 27, 2012 - linkwhile i agree with your point of view, but AnandTech rarely review abnormalities over time. and bear in mind AnandTech is more akin to C&D not CR because AnandTech receives cherry picked product directly from manufactures. and you really have to hope what you buy from your local frys is the same as the one they choose to send for reviewing.
lyeoh - Thursday, March 29, 2012 - link6 month period? OCZ's poor track record goes way back longer than that: http://www.behardware.com/articles/831-7/component...
You haven't even provided a good reason why anyone should care about your opinion on this subject especially since you said "6 month period".
I'd believe BeHardware's article more than I'd believe you, especially since a few simple Google searches for product problems do not disagree with their statistics. So it's not just a freak incident where only the french retailer has higher rate of returns for OCZ and corsair stuff.
fausto412 - Monday, March 26, 2012 - linkI have a 6990 and a n AX850 PSU...that psu gets super hot when gaming. Can't imagine a 550 watt psu not melting. I think the days of the 550 watt psu are over unless you only do single card gaming and don't use the highest end cards.
Ken g6 - Monday, March 26, 2012 - linkDid you miss the GTX 680 review the other day? http://www.anandtech.com/show/5699/nvidia-geforce-... The 7970 would work fine with a 550W PSU too.
Also recall that the 6990 is effectively two cards in crossfire on a single board.
Samus - Tuesday, March 27, 2012 - linkI run a GTX570, Core i7-950, 12GB RAM, 5 hard drives and some other shit off a PCP&C 500-watt PSU. Whole system is reasonably warm after hours of gaming and is completely stable.
Kill-A-Watt has never reported more than 400-watts drawn from the wall, so my 500-watt PSU never even hits 80% load.
Any never system with a single GPU draws less power, I guarantee it. 550-watt is overkill for most people with current technology. Remember most OEM systems still ship with 250-watt PSU's.
Stuka87 - Monday, March 26, 2012 - linkI use a Antec NEO-ECO 520C with my over clocked 7950 and its perfectly fine. I never get anywhere close to even 400W at peak (And thats with a 4.1GHz Phenom II) when measured at the wall. The latest chips from AMD and nVidia are incredibly efficient. The 6990 is a pretty big power hog comparatively, and it is a dual GPU card.
