Connectors:::...

Despite there being plenty of length to the cables, the lack of any braiding for the main ATX power feed gives the Super Tornado a slightly messy look. It could be argued that this is the reason for supplying the Dr. Cable spiral wraps but if that's true than an additional length should ideally have been included. Properly organising your cables and wrapping the ATX cables is a lesson in logistics with just the two they supply.

 

Seven 4 pin Molex connectors, while not quite on a par with the ten you'll find on Tagan's 480 watter, is perfectly adequate for a 350watt unit and is actually quite generous. I have a supply here with just four on it!! Needless to say it lives in a drawer most of the time. Serial-ATA drives are catered for by way of a single 4pin Molex to S-ATA power adaptor. Two S-ATA adapters would certainly have been a better option but hey, it beats none!

An RPM cable is available to plug into your motherboard in order to monitor the speed of the internal 120mm fan if your board supports it, and most do, though it may need to run to the "system fan" or "chipset fan" header as few motherboards feature a dedicated "power supply" header.

Performance:::...

Test System:

Abit AI7
P4 2.4 @ 2.4 (idle tests) and @ 3.3 (stress testing)
2x512MB Corsair XMS4400
4x80mm case fans, 3x 60mm HSF fans, 2x 1m lengths of EL cable with inverter, 4x 12" neon tubes+ inverter (stress testing)
Sapphire Radeon 9800 Pro (GeForceFX 5800 Ultra used for stress testing).

 

I can think of only two words.....rock solid! Granted I didn't quite pile on the punishment the way I have with some of the higher capacity power supplies I've tested but even allowing for that the voltage variations were minimal.

This isn't the entire story where power supplies are concerned but to be able to pull off such a great performance and maintain 100% stability even when I ran our AI7/2.4c test rig combination overclocked to 275MHz is a major achievement.

 

Conclusion

The 3DVelocity 'Dual Conclusions Concept' Explained: After discussing this concept with users as well as companies and vendors we work with, 3DVelocity have decided that where necessary we shall aim to introduce our 'Dual Conclusions Concept' to sum up our thoughts and impressions on the hardware we review. As the needs of the more experienced users and enthusiasts have increased, it has become more difficult to factor in all the aspects that such a user would find important, while also being fair to products that may lack these high end "bonus" capabilities but which still represent a very good buy for the more traditional and more prevalent mainstream user. The two catergories we've used are:

The Mainstream User ~ The mainstream user is likely to put price, stock performance, value for money, reliability and/or warranty terms ahead of the need for hardware that operates beyond its design specifications. The mainstream user may be a PC novice or may be an experienced user, however their needs are clearly very different to those of the enthusiast, in that they want to buy products that operate efficiently and reliably within their advertised parameters.

The Enthusiast ~ The enthusiast cares about all the things that the mainstream user cares about but is more likely to accept a weakness in one or more of these things in exchange for some measure of performance or functionality beyond its design brief. For example, a high priced motherboard may be tolerated in exchange for unusually high levels of overclocking ability or alternatively an unusually large heat sink with a very poor fixing mechanism may be considered acceptable if it offers significantly superior cooling in return.

 

The Mainstream User ~

What can I say? A near faultless execution combined with extremely low operational noise makes the Super Tornado a superb choice for the regular user. Without going overboard it offers all the power that the vast majority of us will ever need and pumps it out cleanly and constantly. At 80% efficiency it could even pay for itself!

The price is perhaps a touch high compared to some units available but without a doubt you should be prepared to pay what ever it takes to equip yourself with the very best available, and the Super Tornado fits into that category and possible even tops it.

 

The Enthusiast ~

As an enthusiast product just about all the Super Tornado 350 lacks is muscle. If you can happily run off a 350 watt supply then the Super Tornado is probably as good as anything else you can buy at this time. It lacks the power and the sophistication of something like the Tagan I reviewed a short while back but it makes up for this with its extremely low noise and stable operation even when pushed.

With a street price of around £62.50 the price isn't the most attractive on the market and I'm sure it could be lowered a bit, but if you want the benefits of quiet, 120mm cooling and apparently unmatched current stability then it's a reasonable price to pay.

Low ripple, high PF rating and top notch efficiency serve to make this an impressive unit that does what it says on the box and in some style. A very nice product!
