Performance (40% of the final score) - now how do I score something that is seriously lacking in North American competition? I suppose I'll just wing it. This is a 1500W unit, rivaled by only one other power supply on this continent for sheer output capability. This is a power supply that was able to hold its own with the Enermax Galaxy Evo in terms of ripple suppression until it went and passed the output capabilities of said Enermax. This is a unit that put out some hundred and ten amperes of 12 volt current, all while regulating within 1% in the hot box. This is a unit that would not shut down in the hot box, even when confronted by temperatures well in excess of the specified operating temperature. When you get right down to it, this is quite simply the most awesome Enhance built unit I have ever seen, and in my view it is more than worthy of this here 10 I'm giving it.
Functionality (20% of the final score) - what more can a guy ask for here? This unit has all the cabling one could ever need for anything short of a thirteenth SATA device. But you know what? Those SATA connectors are 250mm apart on their cables. You could easily add more if you wanted. But that's also where the ST1500 comes up short... in those long 250mm stretches of cable. Like all big Silverstones, those connectors are all just too far apart for me. So, I'll have to go down to a mere 9 here.
Value (30% of the final score) - this is going to be a tough one. Why? Well... there's no real competition other than the big Ultra unit. This bad boy is currently going for $362.99 at Sundial Micro. The older Ultra X3 1600W can be found at just under $300, but that's only because the X4 is out now, and that X4 is currently not any cheaper. That's not even mentioning the fact that I don't currently know how either Ultra performs compared to this one. Really, if you need something this powerful, you can't do better for this price, at least not right now. 10.
Aesthetics (10% of the final score) - as usual, I love the matte black. But, I'm going to remove a point for the sticker frenzy on a surface I could see through the window of my Twelve Hundred, and for an embossed Silverstone logo I couldn't see in any case I own. 9.
I've been waiting for a long time to say this - Silverstone has a real honest to goodness class leading winner here. Not only is the ST1500 the second most powerful unit you can buy in North America as of November 2009, but it's among the best performing units I've tested at any level. Ripple and noise was well in check, efficiency was flat out awesome, the unit ran cool, and the unit ran quiet. Though not many people will ever need the amount of power this monster puts out, even as a 1200 watt unit it stands out. What are you waiting for? Go buy one.
very good ripple and noise suppression
no shuttie downie or death even with temps well over 40 degrees at full power
enough cabling for four video cards, and they all get a 12V rail to themselves
too long cable stretches between Molex/SATA connectors
nothing at all
