So Enermax introduced what is actually the first power supply in the Platimax series that was granted a Platinum certification by the 80PLUS organization (the people that certify and test efficiency). But what does a Platinum certification entail ?
Well, we have bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than a normal unit. Below youll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.
Efficiency at 20% Load
Efficiency at 50% Load
Efficiency at 100% Load
80 PLUS Bronze
80 PLUS Silver
80 PLUS Gold
80 PLUS Platinum
Enermax rated the product at a maximum 94% efficiency, and they are so proud of it that they put a little crown as logo on the PSU itself :)
You can expect five new models on the market in the flavors ranging from 600 to 1200 Watts of power. All new in the (rather heavy) PSU is Copper-Bridge Array transmission technology which replaces conventional wires to provide up to 3% better power regulation
Enermax says that this enhancement will deliver cleaner DC power and raises the overall system stability.
Depending on the model the Platimax series features between three and six 12V rails rated at either 25A or 30A each, and their combined power output varies according to the model. The cheapest 600W model thus has three 12V rails at 25 AMPs each, yet combined this 600W unit has a maximum 12V amperage of 50A. 50A x12V = 600W on the 12V rails alone. Yep it's Enermax, always bringing you a little extra.
The 750W unit is rated at 62A and the 850W PSU 70A (the model we test today). The two top models 1kW and 1.2kW units can provide a maximum of 83 and 100 Amps, respectively.
High-efficiency typically means the loss of modular cabling, yet Enermax somehow managed to keep a modular design for the Platimax series. All models come bundled together with a wide variety of PCI Express connectors (both 6 and 8-pin) as well as with various SATA and MOLEX plugs.
Outside of the 80PLUS Platinum certifications, which ensures that the PSUs are able to deliver at least 92% efficiency in any usage scenario, Platimax power supplies are also compatible with the ErP Lot 6 standard meaning very low power draw when your computer is powered off or is in standby or Hybrid mode.
The PSU's features include 105°C Japanese electrolytic capacitors, a 13.9cm Twister-bearing fan (900 to 2000 RPM working speed), as well as the now standard CordGuard and HeatGuard technologies. The HeatGuard is designed to keep the fan running for a little while after the system was shut off in order to allow for the PSU to cool down properly.
Platinum certified PSUs are expensive to make and as such prices will be higher than normal, expect a range from $179, for the entry-level 600W unit, up to $329 for the top of the line 1200W model.
Enermax Fulmo GT review We review and test the Fulmo GT. Enermax has been going very strong with their power supply and fans. For a while now they also offer PC cases, and more recently they released what seems to be the biggest chassis I've ever laid my hands on. This chassis series has HPTX support for the bigger than biggest motherboards and some pretty cool features as well.
Enermax KW001 Briskie Keyboard mouse combo review Keyboard kits come in all sizes, shapes and forms .. and that's next to a gazillion of manufacturers that offers them. Surprisingly enough a few weeks ago Enermax, the guys behind the best power supplies and the brightest fans also launched a keyboard/mouse combo. Briskie is all about value and as such for 25 USD/EUR you get a mouse and what we think is a very decent wireless RF keyboard.
Enermax Platimax 850W power supply review Enermax always is able surprise us, they now have released the Platimax power supplies, that means a platinum certification and yeah .. that boils down to a 94% efficient product. Very few products get this certification. Today we'll grab a couple of older older supplies and see if what they claim is true, can we really save on energy. We fire off three PSU's at a P55 / Core i7 870 based system setup with a GeForce GTX 590. We then monitor power consumption in idle, CPU productivity (stress) mode and then lock into a gaming session.
Enermax MaxRevo 1350W PSU review The MaxRevo is 1350 Watt .. with peak power available up-to 1620 Watt, yummie. Interestingly enough this is a nice small sized power supply, you'll hardly hear it, has plenty of modular options, wwell read is all modular and is 80 PLUS Gold certified. That makes the modular cables based MaxRevo PSU series 88-94% efficient @ 20-100% load.
