550W Roundup: Three PSUs at Different Prices
by Martin Kaffei on October 28, 2010 4:00 PM ESTOCZ Fatal1ty Internals
Here we have a typical Sirtec design with three heatsinks and so-so soldering quality. The EMI filtering is equipped well, but there is no MOV. It's nice to see that there are no Transcend Electrolytic capacitors from China; now they use Teapo, even if they have chosen the cheap models. The Teapo LH doesn't have the longest lifetime and lowest ESR; however, we've never detected a problem with Teapo in power supplies.
Note that the X-cap behind the entrance is isolated, since there is not much space between the entrance and the heatsink in the secondary circuit. In summary, the Fatal1ty has better caps and better insultion than the OCZ ModXStream Pro. Nevertheless, the improvements are not enough to really make this a new product. It's a decent design with a reasonable price, but despite the Fatal1ty name you won't get any extra frames per second. Now let's see how it performs in our tests.

I also was stung by an Antec about 5 years ago. I read later that they switched suppliers at some point and quality suffered. I switched to FSP and later Corsair/Seasonic, so far so good.I had a small form factor FSP die on me mysteriously but I suspect that was due to the level of chalk dust in the room. I replaced it with a Seasonic, which has been amazingly quiet and reliable.

That was the 2005/2006 Fuhjyyu capacitor incident. It affected the TruePower, TruePower II, and Smartpower units. Those PSUs were shipped with Fuhjyyu capacitors on the secondary, which are extremely unreliable. Antec claims their manufacturer (CWT) put them on without permission to save cost; CWT claims Antec specc'd them that way. Either way, Antec and CWT parted company, and now all Antec PSUs use Japanese or mid-range Taiwanese capacitors.In other words, they had some bad units in 2005/6, that doesn't make them bad for all time. Their current lineup is excellent, baring the Basiq line.

Saying a power supply exploded at 50% load is not enough. For maximum impact, post photographs of its remains after attempted use.sviola - Friday, October 29, 2010 - link
Nice Review. I look forward for more reviews like this and, who knows, a PSU round-up in the same way of the gpus and memory round-ups.iamezza - Friday, October 29, 2010 - link
Loved the review. I liked the humorous writing style and didn't think it was too unprofessional.xi0s - Friday, October 29, 2010 - link
PC Power & CoolingNice review, though seeing how simple it is to test PSU's and how many more players there are on the market these days, I would've much preferred a roundup of atleast 5 PSU's instead of a measly 3. Not that you didn't make a point here, but surely you could've done more with it.

Why get an Antec TP-550 when you can purchase a Seasonic SS-560KM Modular Power supply for a few dollars more and get top-notch performance and reliability ?Corsair power supplies (manufactured by Seasonic) are also excellent too. But the Seasonics are the best.

is actually a pretty big fan company in the asian PC market.they sell there fans in the big consumer electronics stores that have a DIY PC
section, and in hobby stores. (here in japan)
i will say that they are cheaper than most fans, but not the absolute cheapest.

Why bother with a PSU that is not available everywhere?Restrict reviews to components that are available worldwide.

Fanboism doesn't make a good PSU.Thankfully a few sites conduct proper load testing of PSUs so intelligent PC enthusiasts can make an informed decision. Without actual test results of specific PSU models a consumer has no means to tell good PSUs from ad hype. An educated consumer doesn't buy hype they buy quality, performance and value.
One accurate PSU test is of far more value than a baseless fanbois opinion.
