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 had a Thermaltake ThoughPower (can't remember exact model) that performed fairly for 5 years. It operated non-stop for 1 year in-between that time. I bought it separately from a Thermaltake Case, that had several fans. Worth every dime, both of them.But...
I had to replace an original case fan, so I decided "what t'e hell' and slapped a cheap-o-dozen fan in its place. VERY. BAD. IDEA.
The whole thing worked fine for 6 months, then the ASUS metering software showed steady voltage dropping, curiously on the 3.3V rail as I later found out. Then it alarmed in an intermittent fashion, for no apparent reason, as it got to 10% Low Voltage on that rail.
Guess what? The fan LOCKED, and effectively pushed the PSU to 110% or above (who knows?), FOR FREAKING 6 MONTHS.
THE PSU DIDN´T QUIT ON ME.
As I opened it for regular maintenance (hey, 6 months, remember?) I found the locked fan, and a funny smell that could be felt only very near the PSU vent. You know the smell, don't you? That's the smell of a dying PSU. The fan almost burned my hand when I touched it, proving that the PSU was not at fault; in fact, it performed above and beyond any expectation, and possibly avoided a fire hazard. It was still operational when I removed it, but the smell was ever greater each time it was turned on, even for a few minutes, proving the whole thing had collapsed after all that operating time. The fan didn't short out, which would have triggered any safety (fuse, probably?) on the PSU, it just didn't rotate anymore on its bearings, and became a power drainer on the circuit, eating away the average life-time of the component.
The good PSU purchase decision not only proved a wise decision, it avoided me lots of hassle and grief. The cheap fan, on the other hand, destroyed a perfectly good piece of equipment.
"Caveat Emptor" indeed.

It seems right from the start that you have something against TechSolo, you also talk about how it was loud at almost 30dbA, but yet, the Antec is at 32 and the OCZ tops at 26, still close to that 30dbA level."If you want to have a silent computer, please buy another power supply and protect your ears." Couldn't this have been said the same for the Antec since it was actually louder than the TechSolo?
When doing doing these type of articles your supposed to have an unbiased opinion and its pretty obvious from the start that that wasn't true.
