The most abundant PSU company in our review was TTGI.  Most users have not even heard of TTGI before, let alone SuperFlower.  Interestingly enough, that hardly upsets SuperFlower, who continues to mass produce products under various OEM and discreet labels. Given their unique market position, we took the chance to look at several offerings from TTGI.  Their largest power supply is the 520SS, a 520W offering with 4 fans. 

Again, the variable fan control makes an appearance.  As you will see later in this review, the fan control is the Achilles heel for these power supplies.  TTGI’s good prices and good features make these units very attractive, so performance becomes the most important issue with these units.

Features on the TTGI units are fairly bountiful.  All of the units come in a glossy finish which really would look sharp in a case with windows or other acrylic.  Our unit also came with one quad LED fan.  In our opinion, it probably would have been more appropriate to ship the power supply the same color fan as the finish (or at least just one solid color).  If you are particularly handy, replacing the fan will be no problem.

Like the Vantec Stealth, the TTGI 520SS has an unusually high +5.0V rail. The +3.3V rail is not penalized as much, so we will not criticize them on that.  Do keep in mind that an Athlon 2200+ XP runs on about 60W, so overclockers should consider all the options when looking at these power supplies.

Pricing on the TTGI series is extremely aggressive.  The 520SS runs around $85, much less than the other power supplies running about the same wattages.  (The three fan version runs a little bit less, around $75).

    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...

    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?

    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.

    They didn't look at the seasonic brand. recommended here

    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.

    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).

    This is actually the third power supply review on Anandtech. Not the second as you wrote.

    #16, please check out for information on power consumption of several common CPUs (especially AMD).
