2003 Power Supply Roundup Part II: Better Faster Cheaper

We saw the elegant and simple TruePower a few months ago, so we were pretty excited to see if Antec had any other products in the PSU industry we could include in our roundup. The TrueControl 550 is Antec’s highest end product, allowing fan control through a designated 5.25” bay controller. Memories of our Sound Blaster LiveDrive instantly came to mind.
The controller itself is very utilitarian looking, but it seems to get the job done. For all Antec's worth, they probably could have made the controller look a little more appealing.
Antec clearly spared no expense on the 550W TrueControl, and we noticed this is a very different supply from the 430W TruePower we saw several months ago. Several interesting things caught our attention. First, this is the only power supply we have seen with an external rear molex connector. We are not really sure why, but there must be some applications for such a feature.
Also present were black molex connectors. Almost every power supply we have seen to date uses white or clear molexes. Besides the 7 standard molex connectors, the unit comes with 2 fan only connectors (also present on the TruePower 430W). The forward bay allows for control on the internal fans, as well as the fans along these designated fan control rails as well. A very interesting feature, but it is perhaps limited in usefulness. A motherboard fan control connector is also included.
Also, the TrueControl 550 comes with dedicated molexes for fan control. The 5.25" bay is capable of controlling these fans through the power supply. This is defiantly a nice touch since we have previously questioned whether the dedicated fan molexes were worthwhile.
Again, Antec makes the point of demonstrating that the TrueControl 550 has separate lines for each of its 3 main rails. The real element that separates this power supply from the ThermalTake PurePower is the variable voltage on the fan controller. Using the included tool, the unit allows you to modify your voltage settings to adjust within %5 each of the three main rails (+12V, +3.3V, +5V). While this is incredibly useful if you are a die hard overclocker, it can be very hazardous if used incorrectly. For example, underpowering your +12V rail might result in underpowering your P4 or video card, which will eventually damage your components if not careful.

On paper, the theoretical combined 530W maximum impresses us. Remember, the unique feature about a lot of Antec power supplies is that they have separate rails for each of the three main power lines. The advertised +12V rail comes in very respectably at 288W. This power supply will work well for the hungriest of AMD or Intel systems. Die hard overclockers will enjoy the control over each rail, which is also offered on the PC Power and Cooling TurboCool. Be warned though, variable pot controls can seriously compromise your system's stability.
Unfortunately, this supply also weighs in as one of our most expensive units. This is somewhat against the grain of our last Antec power supply which was priced very moderately. For $130 you get the fan controller, and a lot of extras. The dedicated power rails are worth it for a serious overclocker, so albeit expensive, the TrueControl 550 still does not disappoint.

#11, yes P=IxV, but the power ratings in the table were obviously taken from manufacturers' data rather than actual measurements, which is why when any power rating for any of the positive voltages is divided by that voltage, the quotient exactly equals an integer. That would not be a problem if all manufacturers applied identical standards to their specifications, but many computer users have learned that this isn't the case.Anonymous User - Saturday, August 2, 2003 - link
Perhaps you could include a Q-Tec PSU in the next review? They retail here in Sweden at about 60% of the price of corresponding Enermax and other high quality units, so assuming they aren't totally lousy they're very cheap.Anonymous User - Friday, August 1, 2003 - link
I agree with #15. Definitely take a look at the PC Power and Cooling 400w Silencer PSU. I own two of these units and they're very high quality with reasonably low noise.Anonymous User - Friday, August 1, 2003 - link
Enlight power supplies are always being excluded from these PSU comparsions. I have a Enlight 360W PSU and it's very stable and very quiet. Test some Enlight PSUs!Anonymous User - Friday, August 1, 2003 - link
I appreciated the comments concerning AMD users, but what I really need is some sort of guidance on AMD processor speed vs combined power or 3.3V rail current for upgrading older systems. Many older cases have limited power supplies and I'm trying to figure out the fastest processor I can install and still have reliable operation. Example: A 300 watt supply with 25A of 3.3V can only support up to a Athlon 1600+ on an ECS K7S5A Pro or a 350 watt with a combined power of 200W can support up to 2200+. Oh, and forget that old 250 watt power supply altogether. I need something like that... yeah, I know: your mileage may vary, void where prohibited by law, no watts were endangered in the making of this article.....:-)Anonymous User - Friday, August 1, 2003 - link
Next time you guys might want to check out the PC P&C Silencer 400. It's built just as heavily as the Turbo Cool but with a quieter fan.Anonymous User - Friday, August 1, 2003 - link
Hey guys, im sure 1 or 2 of you resistorheads are an ee or will soon be one.. ripple and noise are only part of a good pwr supply.. we need the facts... how many watts do these power supplies really put out. how do they respond with a big load.. will they take an overload.. how well are they protected...thats what i wanna read aboutMIDIman - Friday, August 1, 2003 - link
WOW - excellent review. I'm getting a zalman for my silent box.Nice to see you guys pumping out articles quickly again! Thanks!

hey just wondering the allied A400ATX hows that compare with the B400ATX thats offered on newegg? any differences?Anonymous User - Friday, August 1, 2003 - link
#10, doesnt P=IV? The Power and Voltage measurements were given.
