As I mentioned, this is a fairly bare-bones rig, so unfortunately, I really can't put the Rocketeer IV to the SLI test.
Using my trusty multimeter, the +12v was at 12.24vdc, and the +5v was at 5.06vdc.
I turned all of my fans wide open, ran various applications that ran both the optical drive and hard drive at the same time. I ran Prime95 for an hour. I ran folding@home. I played several games. I played Battlefield2 while defragging. I raised the voltage on my processor and RAM. I overclocked my CPU more. Nothing I did moved the +12v from 12.24, which is well within the standard 10% tolerance.
In standard fan mode, the Rocketeer IV is inaudible above the other fans in my very quiet rig. Pushing the "Turbo Fan Switch" definitely makes it the loudest component. As I mentioned earlier, it is pretty unlikely that you would ever really need to run the PSU fans at full speed.
Oh, and I almost forgot, the LED fans emit a nice blue glow.
In this day of power-hungry rigs, the Spire SP-600W Rocketeer IV more than fits the bill, with a respectable 20A on each of the two +12v rails. Its modular construction makes cable management a breeze. The shielded cables are not only functional, but are a nice change from standard black mesh cables, and of course, infinitely better than no mesh at all. As of this writing, it has not yet attained nVidia SLI certification, but the specs exceed nVidia's highest SLI certification requirements.
The Spire SP-600W Rocketeer IV sells for $120USD at a popular online hardware retailer, which is about the average price for a high quality modular, dual rail PSU.
Dual +12v rails with 20A on each rail
Cool silver mesh on all cables
I really didn't find these important enough to be called "cons", but...
Power cable is a little stiff
4-pin Molex cables could use an extra connector or two
And the Spire Rocketeer IV earns the OCIA.net Seal of Approval.
Thanks to Spire for supplying us with this review sample.
