OCZ Fatal1ty 700w ATX PSU
Simulated Load Testing
Published: 25th February 2009 | Source: OCZ | Price: £108.09 |
To provide our readers with the most accurate results, Overclock3D uses a professional grade SunMoon SM-268+ ATE load tester capable of placing a sustained load of 1690w across a total of six rails (including +5vsb and -12v) on the PSU. Unlike our previous resistor-based load tester, the SM-268+ gives us the ability to adjust amperage loads in increments as small as 0.01A while also measuring voltages and wattage readings on-screen.
During today's tests, we will be placing the Fatal1ty under 25%, 50%, 75% and 100% load levels at both room temperature and inside a hot box regulated to a temperature of around 50°C. Additional cross load tests will also be performed under these conditions to simulate how the PSU would perform with a heavily uneven distribution of load.

You'll have to excuse me for jumping right to the end of the results, but as we can see from Test 5, the OCZ Fatal1ty DOES NOT like being heavily cross loaded on the +3.3v and +5v rails. Even though the voltage results remain quite reasonable, the efficiency levels drop to a rather nasty 72.65%. Of course, unless you're running some archaic PC like a 386SX it's highly unlikely you'll ever see results like this in real life.
The rest of the results are above average, but nothing really stands out as "woweee" great. Voltage outputs start quite high in Test 1 and drop by around 2-3% by the time we reach Test 4. With the exception of Test 5, efficiency sits at around 85% and only drops as low as 80% when very little load is exerted. Throughout the testing the unit remained extremely cool and didn't get noticeably noisy at any time.

Popping the Fatal1ty inside what has been affectionately labeled as the "Pie Oven" by members of the OC3D Forums, we get the chance to see how the unit performs at a baking hot 50°C. Interestingly, very little changes across the board, with the voltage outputs remaining almost identical to the room temperature results and the only visible differences being noticed in the efficiency levels that drop by around 1%.
Testament to the cool running of the unit as seen in the room temperature tests, the Fatal1ty adds very little additional heat to the intake temperatures....in fact, in most cases the exhaust temps are actually LOWER than intake!

Finishing up with some shots from the scope during the 50°C tests, I think it's fair to say that the Fatal1ty did pretty well. Ripple and noise on the +12v rails stays at 40mV or less in all tests including crossload ones, and the +3.3v and +5.0v rails manage to stay under 15mV in everything but Test 5 where the +3.3v hits 17mV.
Now let's move on to the conclusion where I attempt to condense the previous 4 pages into a few paragraphs.

...also, the last line of the conclusion (cons) shoudl should be should (try typing that drunk)EDIT: Also nice to see the hotbox being used and to see those readings remain solid

More seriously, I think I wouldn't be buying this psu. Its effiency is rather good, but for example the cooler master silent power series is slightly more efficient (iirc) and also slightly cheaper. And I don't like having someone else's name in my rig >:'(

nice typo spot - fixed

I don't think this psu is the only one that skimps on connector types. It's obvious to see that the makers are believing u need 1jiggaW of a psu to attempt any dual card setup.
Or perhaps trying to convince the public.
I see a good selection of psus with similar specs and prices with silly shortfalls.

Some of the images of the internals i noticed they have been a bit haphazard with the glue gun. seems like its plastered all over the place.
Also the link to the forums at the end of the article seems to be broken??
Kind regards

Seriously tho, it does look a bit haphazardly placed but it is there simply to help space out some of the components and prevent them from touching others nearby. Larger PSU's don't generally have it, but these compact little ones where everything is squeezed together often have lots of white stuff splurged everywhere.

Nice review matey, I really don't like the way companies use the fatality branding on stuff to make it appeal, but the PSU seems pretty good so I can forgive.
Seems that SunMoon was well worth it. I can't help but feel that this Fatal1ty stuff is being strung out way too long now though. The red LED's are sexy and all, but what could he honestly have helped with during the development of this PSU, besides pointing out where his logo should go? It's all marketing fluff tbh. It is decently priced though.
Another small typo btw:
Should be either "with the potential to" or "which can potentially".Obviously there's a certain irony here in that the only part of a PC system with the potentially cause serious injury or death

Do my eyes deceive me...Is that three adjustable pots sitting around looking sexy on that daughterboard there? Yes, yes it is. I'm not 100% sure if these are for fine tuning rail voltages, or just for making adjustment to the fan speed - as the board does actually double-up as the fan controller, but if you're into poking around inside PSU's with a screwdriver only milimetres away from the mains EMI filter, why not let me know!

I'm just waiting for the review that says "I don't know what happened.. I was testing away and suddenly it just blew up for no apparent reason, must be a manufacturing problem" with a picture of you with a full sooty face and charred clothes poking a fork in the plug socket to try and lever the plug out.
