2003 Power Supply Roundup Part II: Better Faster Cheaper

We took a long look at every valuable bit of data we could manage to squeeze out of the power supplies available. If anything, the most startling data we found in this review was the disappointing problems with some fan controls. We recommend not buying a power supply with an onboard fan control.
Overall, the surprise victors of this roundup were Fortron and Zalman. Both included virtually identical units in the review and both performed extremely well, especially in the sound tests. However, since the Fortron units are priced about $20 lower than the Zalman units, we have to give our editor’s choice award to the Fortron. ThermalTake came in very strong, with very low noise and very high stability. The $74 cost is high, but considering the other external fan control power supply costs $60 more, we think the cost is easily justifiable.
As with the last roundup, we were very impressed with the Enermax power supplies. If their price was not so inhibitive, we would give them a stronger recommendation. Kudos to Enermax on both of their power supplies represented.
The PC Power & Cooling TurboCool 475 surprised us the most. It had excellent performance, low heat and relatively good price. However, when on, this power supply sounds like a train. One could easily modify the fan, but this would probably throw the unit out of spec and change the performance.
Unfortunately, like with any roundup, we can not include everyone. Fortunately, our power supply roundups are cumulative. Next time we do another PSU roundup, we will include the models we have listed here as well as a few other ones. If you have a particular PSU you would like to see included, feel free to drop a line in our forums so we know for next time!
Once again we would like to thank Directron.com for sponsoring this review and donating the hardware for us to test. Furthermore, we would like to thank the folks at Maxpoint, Kingwin, Case-Mod.com for providing hardware and testing equipment.

I cast another vote for us to be able to get a copy of the modified version of memtest86. I'd love to check to find out how much bit-flipping is happening over time on my various PCs. In addition, it seems to me that it would be a good way to see if ECC memory is actually doing what it should be. (If a bit gets flipped on a board with ECC memory that's supposed to support ECC memory then there's obviously something wrong).Also, you should give a copy of your modified source to the memtest people so that they might include the long delay time as an option in a new version.

Any chance of a review of the silentmaxx fanless 350W. This thing has no fans so in theory it should be 0Dba! Not sure where the poewsupply is up to the job though on the poewer front - a review owuld be great. Cost as you probably guess is on the high side...http://www.silentmaxx.net/silent_products/power_su...

To me the most interesting data from this roundup was the instability a PS can cause to a system. I think this subject is worth a dedicated article. Also how can we reproduce this data at home? Where can we get the modified memtest86?Anonymous User - Wednesday, August 13, 2003 - link
Hello!!??? Seasonic power supplies?? These have to be the quiestest power suplies I have ever (NOT) heard. Appears to be pretty well constructed. These should realy be included in any decent, comprehensive power supply round-up.Anonymous User - Monday, August 11, 2003 - link
They didn't look at the seasonic brand. recommended herehttp://www.silentpcreview.com/modules.php?op=modlo...

I got a PC P&C Silencer 300 a while back, and I was very unimpressed with its noise level. It was hardly quieter than the cheapo PSU it replaced. My Enermax 365 and Antec Truepower 350 are much better.How about reviewing Seasonic? I hear they're super quiet. A little hard to find, though...

Untill all power supply manufacturers get it together and sheath their cables, we are pretty much stuck with what they offer. I solved this in my window case with some electrical conduit from the auto parts store. there are a few color choices including your basic black, but any of them make a world of difference hiding those unsightly P.S. cables. That and a little electrical tape over the white connector and they almost disappear.Anonymous User - Monday, August 11, 2003 - link
Another extremely happy user with a PCP&C Silencer power supply. I do have to question just a bit why the reviewer didn't find out about their existence on his own, noise being the primary complaint in his review (though I imagine the sheer number of power supplies being reviewed and perhaps deadline pressure could have been factors).Anonymous User - Sunday, August 10, 2003 - link
This is actually the third power supply review on Anandtech. Not the second as you wrote.Anonymous User - Thursday, August 7, 2003 - link
