Scoring is done in four categories: performance, functionality, build quality and value.

Performance (40% of the final score) - Efficiency was close enough to Platinum to call. The efficiency at stand by was very good as well. Ripple and noise was virtually nonexistent. Rise time was well within spec and there was virtually no overshoot during power up. The +12V regulation was good, but the non-primary rails' voltage regulation certainly didn't shine for us. Of course, non-primary rails are called non-primary for a reason, so I'm only taking half a point away for that. Performance score is 9.5.

Functionality (20% of the final score) - The unit is only semi-modular (higher functionality scores go to fully modular units). Semi-modular isn't so bad if 99.9% of the potential users are going to use all of the fixed cables. Since most of the people that require a 1000W power supply won't need two CPU power connectors, odds are that's going to be at least one cable that will need to be hidden. Ironically, this would be SO EASY for Enermax to address. There are THREE modular connectors that support either CPU or GPU power connector cables, yet only two GPU power cables are provided. If Enermax would have just left off on of the two CPU power connectors and included an additional modular one, I would give the Platimax 1000W a score of 9.5 in this category. Instead, I have to give this unit a score of 9 for functionality.

Build Quality (20% of the final score) - Not much to say here. The components used are all top notch and the build quality is near perfect. Score of 9.5 for build quality.

Value (20% of the final score) - Having a look over at Newegg, we find the Platimax 1000W selling for $289.99 without any promotions. That makes it the most expensive Platinum 1000W power supply they currently have on hand; a good $30 more expensive than Seasonic and Antec's Platinum efforts. If the unit being semi-modular bugs you, you can even get the XFX ProSeries 1000W for ten bucks less! My only real complaint with that unit was the marketing overload. I'm still taking Frova for the migraines that caused. Value score is going to have to suffer. I'm giving it a 7.5.

With a total score of "9", the Enermax Platimax 1200W earns a "jonnyGURU Recommended" award.

There isn't much to complain about with the Enermax Platimax 1000W. To not consider this power supply a top contender because the non-primary rails' voltage regulation is average or the soldering isn't absolutely perfect would simply be nit-picking. That's why only half a point was taken off for each. The only real complaints are that we have a modular power supply with potentially one cable that the user will have to hide, which almost negates the advantage of the power supply being modular in the first place, and the rather high price tag.

The Platimax 1200W was nice because it was fully modular, but the voltage regulation wasn't as good as this unit and the efficiency wasn't as good. I dare say if you were considering the Platimax 1200W, but know that a 1000W would power your system without a problem and won't miss the full modularity, you're going to be much better off with the less expensive Platimax 1000W.

Overall, Enermax brings us a superbly built power supply, capable of 1000W and with incredible efficiency at every load. The unit looks good and brings the consumer a few of the advantages of a modular power supply. If they were to improve the DC to DC performance, take off one of the fixed CPU power cables and make it a modular cable and bring the retail price down about $30 and this power supply would be just about perfect.

The Good:

• Platinum efficiency
• Excellent +12V regulation
• Minimal ripple and noise
• Excellent build quality

The Bad:

• VERY expensive, even for an 80 Plus Platinum power supply

The Mediocre:

• Too many fixed cables for most people, almost defeats the purpose of the PSU being modular
• Non-primary rails' voltage regulation is mediocre
