The VisionTek 80PLUS 800W Power Supply Unit is one of the notable power supplies the company is currently putting out aside from its 1000W Gold, which is a step up in performance to the Gold PLUS certification which ranks higher efficiencies of power throughput with different load levels. The Visiontek 800W Power Supply supplies the perfect performance for a relatively great price for enthusiasts that are not only looking to get at least 85% efficiency for that SLI or Crossfire required setup, but also stability through over-current, short-circuit, and over-voltage protection to make for a power supply unit no one can go wrong with. The testing phases reveal that the VisionTek 800W Power Supply truly lives up to the high VisionTek standard.
Cooler Master releases another powerhouse PSU offering a whopping 1200W for hardcore gaming and technology enthusiasts around the world. After our numerous tests at the wheel behind this melodious creation, one thing is clear: the Cooler Master Silent Pro Gold 1200W, part of the Silent Pro Gold Series matching the 80Plus efficiency standards, satiates a hunger that a quad-SLI/Crossfire X setup can accomplish.
Antec’s TruePower Quattro series is simply one of the best choices for any consumer looking to upgrade their power throughput to the maximum level. Garnering a total of 1000 Watts of pure power, the Antec TruePower Quattro 1000W delivers on the needs of a system that needs to be efficient for either video use, or gaming use. The Antec’s TruePower Quattro provides energy conspicuously across 5 rails while working within the EPS 12V v2.91 certification system, this power supply macadamizes across every torture test, ripple test, and noise test to deliver efficiency beyond 85%.
Antec is known for making great power supplies that last a very long time. In the new addition to the long line of NeoPower pure performance series, Antec heralds the NeoPower 650W high efficiency power supply. The NeoPower features three 12V rails, a high efficiency design, and aims for a better tomorrow for performance. NeoPower’s highly efficient design produces less heat, allowing the use of a smaller fan running quieter at slower speeds. Built to support dual GPUs and the top of the line core CPUs, the NeoPower 650W aims to improve on heat generation, affordability, and performance without compromise for hardware enthusiasts that love both a single and dual powered GPU solution. Continue on to see how it fares as we place it under our severely rigorous power supply analyzation process.
OCZ has provided us with a power supply (via a sale at Best Buy). Duh. Presenting the OCZ PowerStream 520. OCZ made a name for themselves in the memory market by creating top quality products. It looks like they aim to do the same in the power supply market. OCZ has been releasing products that help modders, overclockers, and enthusiasts to tweak their computers for absolute performance. While their memory built the OCZ name its products like the DDR Booster that gave the electron crazed (me) something to drool over. The PowerStream 520 makes it to my short list of power supplies I would recommend to friends, but I do not want to spoil the ending so we will save final judgment until, well, the end duh. On to what makes this power supply stand out.

Most of the features and specifications will be talked about in subsequent paragraphs. What I want to look at here is the simplest to understand part of a power supply, its power. When people buy new cases they often get a cheap power supply included with the case, these end up lasting a few months to a year before they die. The other thing that often happens is the buyer, thinking that they got a really good deal on their 450w power supply, neglected to read the fine print where it says that its 450w peak power and they never notice that the combined power from the 3.3v and 5v rails is less than 200w. There are a few key items that help a person select a quality power supply: first, the weight; second, the combined 3.3v and 5v power rails; and third, the warranty.
One of the more interesting developments in recent days is the purchase of PC Power and Cooling by OCZ. Today we bought their ProXstream 1000W and will take a general look into it. Let’s look at the specs:
Features and Specifications:
- 1000W Configuration
- Dimensions: 150 x 140 x 86mm
- 3 year warranty backed by OCZ’s exclusive PowerSwap replacement program.
- No more endless return-for-repair loops!
- Internal 80mm fan
- 4 Channel 12V Output provides stable electric power to computer components
- 4 Channel PCI-E connectors
- Dual CPU support: provides 8-pin 12V dual CPU support with stable voltage

So, as you can see, this unit has four +12v rails that each pack a whopping 20A on them, giving us a total of 80A of +12v power. They also have a three year Powerswap warranty on this unit, which just adds to the value, and gives confidence to the consumer when they are paying this much for a unit.
