OCZ Fatal1ty 1000W Red Gaming Power Supply Review - Installation and Testing


Installing the OCZ Fatal1ty 1000W power supply is a breeze due to the ease of running and organizing the modular cables, and the little extra wiggle room you find with the individual cables. At first I was a bit concerned about the lenght of the cables, but everything reached in the COSMOS II, but the CPU power connectors were close to not making it.  They're drawn snug, but they don't pull on the CPU power connector, but being that the COSMOS II presents the worst case scenario with most motherboards, there should be adequate length for nearly any case.


As many cases now have the PSU mounted downwards, most of the lighting will be lost to the bottom of your case.  But as is the case with the Cooler Master COSMOS II, it adds a bit of illumination to the bottom bay, and casts a gentle glow out the back.  And for those who love what the Fatal1ty power supply lineup offers but aren't fond of the lights, it won't be hard to shield them enough where they won't be noticeable, but that's completely up to your own personal preference.

Since we are still in the process of raising funds to acquire power supply testing equipment, we do not yet have the capability to do fully stability, power signal quality, and regulation testing.  We don't use our PC to load the power supply, because it's highly variable, and would ultimately result in us drawing conclusions for something which just isn't right.  So rather than doing an injustice to ourselves and our readers by pretending we can draw accurate-enough conclusions from this type of testing, we will stick to a tops-down and high level analysis of how it performs.


OCZ Fatal1ty 1000W Internals

One consideration, and one which is often glossed over a bit in the gaming market, is fan noise.  The fan is a relatively large 140mm HA1425H12B-Z with red LEDs.  140mm fans generally allow for quieter operation than smaller fans, as it accelerates more air, but the air moves more slowly, and the slower the air is moving, the less noisy it is.  The result is an equivalent (or more) amount of airflow, but at a lower noise level.  However, HA1425H12B-Z is capable of running up to 2800RPM, which can be quite loud with a 140mm fan size.  The fan is whisper quiet when at idle, and actually doesn't get as loud as I was originally expecting under heavy load.  It's still not remarkably loud, and often in gaming PCs, it's an afterthought anyway.  Ontop of that, when you're gaming, you're likely to have headset or audio which tones it out, and being under a desk or a bulkier case will further isolate the potential noise.


Throughout heavy benchmarking for testing of components listed in the test setup, we never observed the slightest indication of power instability, not that we'd expect any. The unit employs high quality components, such as Nippon ChemiCon 105°C capacitors, and an overall clean layout, as shown above.  Low profile heatsinks keep the arrangement organized, while still providing adequate fin surface area to keep the power supply cool.  The 12V power is also supplied on a single robust rail, feeding a total continuous 1KW to your power-hungry components across all of the rails.
