2003 Power Supply Roundup Part II: Better Faster Cheaper

We received our quad fan Kingwin supply well before the TTGI units had hit American soil. The unit was well received in the lab, but as we noticed when the TTGI units arrived, practically identical in construction. TTGI and Kingwin obtain their components from the same manufacturers in Taiwan.
During the publishing of this article, we stopped at Kingwin to see what new technology they were working on. One of the more exciting products they were working on was a second generation power supply that contains much different electronic components. Unfortunately, production samples are still several weeks or months off, so we will not have a review any time soon.
Features on the Kingwin KWI-450 were identical to the TTGI units. The power supply comes with a sheathed ATX cable, gloss finish, aluminum housing and an LED fan. Using extra fans provides some relief if one fan were to die. The idea of “extra” fans has gone a long way for video card manufacturer Albatron, and it is our guess that it will continue to stick around for a while.
Like the TTGI units, the Kingwin supplies suffered the same unfortunate performance problems with their variable fan controls. We will discuss in detail these problems later on in the article.

The Kingwin KWI-450 puts out 225W on its +3.3V and +5.0V combined rail. This is about middle of the pack as far as the other power supplies are concerned. The +5.0V rail still seems unnecessarily high.
At $95, the Kingwin power supply is not the cheapest available, especially compared to the near identical TTGI units. We have seen vendors put the Kingwin power supplies in Kingwin cases (which are very well received), so they are still prevalent in the market. Like the TTGI, we thought the Kingwin KWI-450 was a good balance of features and price, but maybe not performance.

i came in here today looking for just the same thing though!we needs a new ps article! thanks in advance anandtech!

Dopey:It's an extremely old article. Nobody reads those except when they need to be pulled out of the vault.

Sad to see no comments since 2003! ???Looking for a good power supply for AMD and review indicates that both Fortron & Zalman are good at not too high price. But looking at Antec True Power 330W I read "beware of the extremely modest +12V rail. If you are running a high end video card, or an Intel Pentium 4, this power supply simply will not produce enough juice." Both the Fortron &n Zalman deliver just 180 watts on the +12V rail while the Antec True Power 330W puts out 204 watts. And if you look at the whole list of PSUs reviewed 204 watts looks like a respecatable amount of power. So ... ????????????????????

I bought the Zalman 300w for $50 as a result of this article. Love it to death, but newegg stopped carrying it.1) What size fan is in the Fotron reviewed here, 120mm or 80mm?
2) What is the model number of the 300w alternative to the Fortron FSP400-60PFN?
3) Isn't the Sparkle FSP350-60PN reviewed here also a fotron, and what is the model number of its 300w alternative?

You state for those PSU's that have good amoubt of voltage for the 3,3V are good for AMD.It will also be nice to say that most new motherboard from AMD are now using 12 RAIL e.g. 8RDA3+ many more and from what ive seen all K8 mobos use 12 RAIL
all in all good review.
What i have found with my TT320W that when you stress it too much and it heats up it will shit down whole system.
Also if your PC is off for many hours if you touch the PSU its worm :S
Ordered my Antec 550W True Control
Also you should show how to short the old PSU so user can use 2 PSU in one system..
I run my whole system on a 480W ProSourse untill my 550W Antec TC is here
My GFFX5900 runs on a dedicated PSU 300W soon it will have a dedicated 480 ProSource :D
And all my 12 fans run on a 300W generic PSU
Also TT's seem not to like when to many devices are connected to it

To know how much the exhaust air will heat a room you have to know not only its temperature but also its volume. It would be simpler to measure the efficiency of the supply.The tests were not very thorough at all because if they were they would have included electrical noise and current measurements and testing at full power.

The memory errors could be due to bad filtering more than cable shielding. Putting a 'scope on the outputs would would provide a graphic portrayal of output quality. <hint, hint> :-)*TimDaniels*

I enjoyed reading the article and I think it was very well written and the tests were very thorough. Although the article discusses "heat" and examines each power supply to see how well they deal with the heat issue, I think from a consumers point of view, you should have measured the difference in the temperature of the exhaust that is emitted from the power supply. For me that is a real issue as the heat that emits from my existing power supply probably raises the room temperature by 7 to 8 degress (to the point of making it uncomforable to stay in the room on a hot day). I want a power supply that doesn't blow out hot air. Which one of these blows the coolest air?Anonymous User - Friday, August 22, 2003 - link
As much care was taken in creating the title as in testing the power supplies.I hope to see another Anandtech power supply review soon, only one with proper testing. I have to give Anandtech an A for effort in this case, but I can't still give them a passing grade. Please consult with a specialist in this field for any future test.

Is it just me or does the article title seems a little off? "2003 Power Supply Roundup Part II: Better Faster Cheaper" Faster? A faster P/S?
