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'm with everyone here, crap power supplies are a plague and with the marketing focusing on the Watts "output" (many PSU are overrated as Martin pointed out with the Techsolo Black Mamba 550W), it just gets worse for uneducated consumers.I wish that ATX specs were tighter and that if anything, PSUs should be regulated by an independent commission whose approval you need to sell a PSU (not going to happen, I know), or at the very least to display their label (like 80 PLUS).
Requirements being based on being capable on delivering promised output (At 50C, not 30C or 40C...), ripples within a certain reasonable range, overcurrent/undercurrent/surge/etc. protection to prevent both fires and to protect the PC components, correct wire gauge and other important things that don't come to my mind right now.
In short, a certification that would tell you that PSU has what you should look for and will work reliably as intended. Just like 80PLUS with efficiency, what a great certification. Not perfect, but it's a big step forward.

Typically the UE and CE certifications should be that governing body when it comes to PSU's. If it is typical for the PSU that burned to have those issues, it should never have gotten certified.Although there is the "Fake" CE mark that looks very similar to the european CE mark, but actually stands for "China Export". I have seen some cheap electronics (and cheap open frame PSU's) with this mark on it before. And of course those PSU's tested out to be crap when ever I hooked one up to my power analyzer.
But an ATX specific spec would be awesome.

"This PSU is not available in the US, but it's still a nice representative of the crap-section."While this may be objectively true (as it appears to be), I suppose I expect Anandtech articles to read less like blogs and more like professional evaluations that give the facts up front and well reasoned, supported and defensible conclusions at the end. At least that is what I have come to expect on Anandtech....please dont turn into Tomshardware (i.e. poor writing with sensationalism everywhere).

I'll just chime in here by stating that Martin is located in Germany and as such is not a native-English speaker. I heavily edit most of his reviews, but it can get a bit tedious at times to rewrite every little phrase. Perhaps I should have been a bit more creative up front, but I let this description of the Black Mamba go through and apparently you guys didn't like it, so I've reworded it to be a bit more professional. Maybe I was just reminded of Michael Meyers: "If it's not Scottish, it's CRAP!" :-Dlenghui - Thursday, October 28, 2010 - link
Well, great job translating, Jarred, and great job writing, Martin. Great review.I happen to own an OCZ Fatal1ty 550W and a ModXStream Pro 500W, so this article intrigued me. I have owned both for over a year, running 24 x 7 x 365. No problem so far (touch wood).

Thanks for changing that. I read that whole article and enjoyed the comparison as I am pretty uninformed about PSU and why one is better than the other, but that one little phrase just kept coming back into my mind when I thought about the article. Keep up the good work!softdrinkviking - Sunday, October 31, 2010 - link
it's not "you guys" that don't like it, it's just one prick.you and Martin are both doing a great job, and i absolutely floored that
you are catching shiite for that one sentence.
i mean, how stiff can you possibly be to take offense at that?

A 550W power supply that blows at 300W actual output is certainly "crap-section" - so, in this specific case, I understand the feeling.dertechie - Saturday, October 30, 2010 - link
Yeah, I actually enjoy the black humor often found in PSU reviews.EddyKilowatt - Tuesday, November 2, 2010 - link
Well the thing performed poorest on the tests, and failed at half rated load... those are supportable and defensible results by my standards.I don't have a problem with Martin's exasperation creeping in a bit early in the review. Everyone with knowledge needs to take a stand against the cheap crap that's always threatening to flood the market and drive the good stuff out. Martin's comment might've been out of line if the Techsolo had under-performed by 10%... but it *failed with smoke* at just half rated load! That's crap, and I'm glad he called it such.
