Just a couple of weeks ago we took at one of the best and largest power supplies we have seen here at Pro-Clockers. It was from Enermax and boasted 1350 watts of pure power and was called the MaxRevo. That particular unit was aimed at the end user needing tremendous amounts of stable power. But Enermax is at it again yet with another power supply that is a little more refined than the MaxRevo, but sporting quite a bit less power. The Platimax is based on the highly efficient 80PLUS Platinum rating which requires the power supplies to maintain 90% efficiency at 20% load, 92% @ 50% load and 89% @ 100% load.
The power supply we will be looking at today is the B620JL, a 620 watt unit from their gaming line. The unit is Bronze rated meaning it has, at a minimum, 80% efficiency rating at 20% and 100% loads, with 85% efficiency at 50% load. Jou Jye have met and exceeded these efficiencies, considering it "82Plus". While there are many power supplies on the market with a Bronze rating, there is something the B620JL has that makes it different from many of the other units on the market. What could this relatively unknown company offer above the rest? Read on and find out, but we'll give you a hint: it involves two power supplies...
The Silent Pro Gold series being one of Cooler Master's best selling power supplies, which they now have decided to take it one step further. Entitled the Silent Pro Hybrid, the new series adds a feature that many will find to be pretty helpful when the load and heat begins to build up. A fan controller is thrown into the packaging to allow the user to dial in the desired speed of the cooling fan for the power supply. So, if noise becomes an issue while computing, simply knock it down a notch.
The ZS series of power supplies from OCZ were just released this year. The series comes in three different wattage ratings of 550W, 650W and 750W. Today, we will be taking a closer look at the 650 watt model. The ZS 650 is a single 12 volt rail model that boasts an 85% efficiency rating. Lets see how well it stacks up against the other heavy hitters that have come across the test bench.
Today, we will take a look at another power supply from Enermax, the MaxRevo 1350W. This one is a behemoth as it boasts 1350 watts and 112 amps across six 12v rails. There is no hiding it as Enermax is gearing this unit towards the GPU-happy, storage-minded and dual-CPU having individual. Yes, the EMR1350EWT (true model name) is aimed at the individual that needs massive amount of power but also want it to be stable and reliable.
The Silent Pro 800 offers all the features and protection found in the big brother, just less wattage. One of the features that made the Silent Pro line a great seller in stores was it met the 80PLUS Gold standards. Call you say 90% efficiency rating? It’s all about going green and conserving energy these days. Added insurance is offered in the form of over and under protection which is a must have when looking for a quality and stable power supply.
The Grand is a dual 12v rail unit that has an unprecedented 125A between the two of them. Meeting the requirement for having an 80PLUS Gold rating, the unit promises to be a winner when it comes to stability and the reliability which is ever present in Thermaltake products. Speaking of quality, Thermaltake is so confident in the Grand series that they are offering a very impressive 7 year warranty on them. Join us as we take a look at this behemoth of a power supply and see if it is worthy of your time and hard earned (or saved) money.
