550W Roundup: Three PSUs at Different Prices
by Martin Kaffei on October 28, 2010 4:00 PM ESTOCZ Fatal1ty OCZ550FTY
The OCZ Fatal1ty comes with the usual assortment of parts: you get a users manual, a US/UK/Europe power cord (depending on your location), and the necessary mounting screws. In addition, the power supply has cable management ("EZMod Technology for custom cabling"), and the modular cables are placed in a separate bag. The distinctive product features consist of a red LED-fan and active PFC—the latter is not that remarkable, but it's a step up from budget PSUs like the Techsolo. OCZ also makes mention of the 135mm fan and 80 Plus certification. The marketing tells us to "get the Gear used by the Pros", referencing the infamous John "Fatal1ty" Wendel of Quake 3 fame [Ed: has he even done much recently?], and we can only hope the pros use high quality power supplies. OCZ offers a 3-year-warranty with support in their forums.
The varnish is shiny, the ventilation holes are tiny, and when the fan is off you can see almost transparant fan blades and parts of the internal design. The depth of the housing is 16cm, which is okay for a 550W power supply with cable management. There is a large power switch in front of the PSU, but no need to mention this as a feature on the packaging.
| Cables and Connectors | ||
| Fixed/Modular | Main | 24-pin 45cm |
| ATX12V/EPS12V | 4+4-pin 45cm / 4-pin 45cm | |
| PCIe | 6/8-pin 50cm / 6-pin 50cm | |
| Peripheral | 3x PATA 45-75cm / 3x PATA 45-75cm + Floppy 15cm | |
| 3x SATA 45-75cm / 3x SATA 45-75cm | ||
The main cables could be longer than 45cm for use in large cases, but this will work fine otherwise. The 4+4-pin ATX12V and one more 4-pin ATX12V is not bad for a 550W PSU. Six SATA and six Molex connectors are more than enough for common PC configurations, and the floppy connector increases the maxmium cable lenght up to 90cm (but only if you need a mini-4-pin Molex, obviously). Finally, the 6/8-pin and 6-pin PEG connectors make for a reasonable 550W PSU setup.
OCZ continues to use a Globe Fan fan with a double ball bearing, which is partially covered by ducting. The fan needs 0.33 amps and has eleven transparent fan blades.

I know your plan was not to privde full market coverage.. but still, if an PSU as expensive as the Antect is included, which still gets "only" 80+ Bronze, it would have been nice to see a 80+ Gold heavy hitter like the Enermax 87+ or Seasonic X series included. In my opinion they're as good as ~500W PSUs currently get.MrS

I really can't see a reason to turning to budget PSU's when there are often great ones on sale.For example, the Corsair 400 W one, every now and then, goes for $20 AR. Antec has a similar offering, at similar price, the EarthWatts 430W I believe. In higher range, another great example: The Corsair 650 TX for around $65 AR. In regards to my personal preference, all of these are known to be very quiet.
Granted, you do have to wait for the good pricing, but I consider it to happen often enough to simply pick one up when they do and have a spare ready. I suppose if you really can't wait, then you'd have to consider the other brands.

I've bought a Corsair CX400 PSU and it's efficient, silent, stable and it around 40 EUR I think.Bought it after reading about it on http://www.canardpc.com/dossier-36-450-Corsair_CX_... (french) (the whole article is a worthy read if you understand french). It's rated at 400W but if you sum up the powers, you get over 500W.

I will always stand by Corsair PSUs. The PSU in my rig, CMPSU-520HX, has been reliable for 3 years. Outlived everything else in my machine (3 video cards, 2 CPUs, dozen of HDDs, 3 mobos, even 3 cases lol). Granted I buy quality parts or don't buy any at all, so none of those pieces actually died on me (except a 4 y.o. Hitachi HDD). I've also put in about 15 of Corsair PSUs in clients' rigs (from 400 to 850W versions, multi-12V-rails and single) in the past year and a half. Not a single one died or caused any instability. All are dead silent, too. Corsair's PSUs has become a standard in my eyes. Yes, there are more efficient offerings but they cost in the upper 100s and mid 200s. Between $50 and $150, I don't even think about what PSU to get, I just approximate the consumption and through the appropriate Corsair in the cart.chrnochime - Friday, October 29, 2010 - link
Well they either use CWT or Seasonic, so they're reliable because of these companies. IIRC they don't have any PSU that's specifically made *by* their own factory, all of their PSU are rebranded ones.strikeback03 - Monday, November 1, 2010 - link
Well, that is the case with most PSUs though. Corsair does pick good ODM designs and specify good components for the builds.HollyDOL - Tuesday, November 2, 2010 - link
I am very happy with Corsair PSUs as well and can only recommend... high efficiency, silent, very good current stability...gusc3669 - Thursday, October 28, 2010 - link
On page 1 under the Techsolo Black Mamba STP-550 I know that this PSU didn't perform but..."It just keeps getting better! This PSU is not available in the US, but it's still a nice representative of the crap-section."
Mr Perfect - Thursday, October 28, 2010 - link
Every once in a while it's good to call out the low end products like that Mamba, especially when it comes to PSUs. There are so many people who buy horribly cheap PSUs, or get one bundled with a case, and then see their whole machine go up in smoke. Which might actually make this more important the testing good supplies...It would also be helpful to explain some of the features and components of the supplies though. I imagine there are quite a few people who don't know what things like PFC are, or even that it existed.

Reading only reviews from decent and high quality power supplies will suggest to the reader that all power supplies are decent or high quality. Good to know (at least every once in a while) that a certain power supply did blew up at not more than half the supposed load
