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.

The VisionTek 800W Power Supply looks as great as it feels. The black plated sleek design is impressive, and the power supply itself comes with the necessary cables to make for any type of connection: including SATA, 2 6-pins, 1 8 pin along with a 4+4 connector as well to double up. Opening up the power supply reveals high component parts that are covered from any hazard, with sleek brown and blue wires running through a green-yellow MBR to capacitor design that is delightful to look at while this PSU is open. In terms of design concept, the Visiontek 800W Power Supply is sleek as the outside box appears, but it can be greater to see some red/black combinations for the VisionTek logo aspect to further the design concept.

Testing is the bulk of the performance, and this point-product testing that we conduct is extremely extensive, including Load Testing, Capacitive Testing, Ripple Testing, Transient Testing and Torture Testing.  The most important parts begin with the Load Testing which is performed at 25%, 50%, 80%, and finally 100% of the rated capacity. All of these reveal that the VisionTek handles the rated output like it says, and forgets to mention in its self-effacing state of the cooler temperatures that it exhibits at most loads. Well above the typical regulation for a 77% recommended efficiency, the unit scores a great 15% above the regulatory marks, creating more performance per watt per unit. Capacitive Testing reveals there is stability to the electric potential of the PSU board when it comes to the Capacitive Loads and often sudden loads in a real-world environment which are hard to emulate. Ripple Testing was marginally, however, revealing that the PSU cut it a bit too close to the max ripple noise when put through the maximum load – the unit’s combined 12v rails peaked at ~75mV which is above 3/4 of the ATX12v specification while the more active minor rail, the 3.3V rail, peaked at ~4.8mV. We would have liked to see less of the ripple peak for the higher maximum load but 75mV is decent well alone. Torture Tests is where the meat of the testing went, over 2 weeks for this one which is usually 2x the testing period of any other power supply. Why? Because this power supply performed amazingly well given the ambient temperatures on maximum of 38°C-40°C. Pushing this for over 4 days reveals there is enough juice in this power supply to last a long time and only makes us wonder how the 80PLUS Gold performs.

The VisionTek 800W Power Supply performs relatively well through all tests and is a great purchase for that moderate hardcore enthusiast in mind that is looking to step up their rig to a SLI/Crossfire performance, and even just a hardcore enthusiast that is looking into not spending too much money for a 1000W power supply when they can get the next best thing at near the offered efficiencies at the rated capacities.

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.

The appearance is simply beautiful of this power supply unit, featuring a black engraving of ‘Silent’ and accentuating the colors of the golden element it represents. The outside is woven with black stripes on top and bottom, white being very easy to look at through the contrast of the colors. Cooler Master could have easily went with a black box, and a white ‘Silent’ with a golden ‘Gold,’ but there is complexity to the outside itself. The actual power supply unit is a sleek black, actually imitating the idea we recommended for the outside box, an even more brilliant concept in all actuality. 1200W is etched on the left side, while the 135mm Ultra Fan is pure gold tinted. The outside and appearances are simply of extraordinary value, something while leaves more hope to the actual innards and working of a power supply unit.

Opening power supply units is one thing WhatIfGaming loves to do in order to see a key ingredient to any successful PC component: build. Build at some point is essentially judging a book by its cover, but a cover such as this uses the same sort of images and assets as other covers where build actually makes sense in terms of the eminence of PC components used. The Cooler Master Silent Pro Gold 1200W reveals Japanese-made capacitors in the shapes of L’s, one of the most manufacturer recognized sort of cooling method derived to give maximum heat output through the fan. Hybrid Transformer, another patented technology, is one of the most interesting things the Cooler Master Silent Pro Gold 1200W only does in this industry: it throws Farady’s law of Statvolts out the door in how one transformer puts out certain statvolts without cooling making any difference in winding turns of amplitude waves. The transformer, the core item in any power supply, itself includes a heatsink for good measure and all these combined leading us to very low and confirmed temperatures of idle at a bare 32 degrees C and torture load of 1150W  at a mere 43.5 degrees C.

The brilliance of the Cooler Master Silent Pro Gold 1200W shines through the multiple tests to display to professional gamers and technology enthusiasts that this power supply works under enormous pressure, notably torture and real world. For the torture test, The Cooler Master Silent Pro Gold 1200W worked beautifully well, outputting with 50% load at more than 92% efficiency and finally at 89% efficiency at 100% 1200W load. Interestingly enough, this power supply delivered next to 1380W when pushed to the extreme, something way beyond its actual specification when tested at load beyond the excess. The quality of the hybrid transformer clearly shines throughout the examination and the best part of all was the actual real world testing followed suit, showing exactly what the Cooler Master Silent Pro Gold 1200W can do.

The Cooler Master Silent Pro Gold 1200W is simply one of the best 1200W we had the pleasure to test that remained at very cool temperatures and laughed at the most extreme Intel i7-980X system with Quad-SLI we could throw at it. The Cooler Master Silent Pro Gold 1200W far exceeded expectations through the tests, remained silent as a key ingredient, and simply measured itself easily into a powerhouse power supply unit that is definitely worth the purchase not just in the real world, but also a consumer’s mind.

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%.

The beautiful exterior of the Antec TruePower Quattro 1000W is simply appealing. Etched with white/black trim lines, the power supply adorns a sense of style while remaining the modernity to provide a power that meets today’s most current demands. The power supply comes with the various connector cables, most noticeable the 2 x 8-pin PCI-E and the 2 x 6-pin PCI-E for a machine that wishes to optimize its dual graphics configuration for processing power or just wants more power for applications able to use it in the near future. The Antec TruePower Quattro provides a design to match the stability of the testing that reveals the continuous outlook power.

The Antec TruePower Quattro 1000W provides a level of testing performance not seen in most other power supplies. Straight out of the box, the power supply was put through rigorous testing and stood out in each one of them. The Torture testing revealed an overall efficiency of 89.24% while monitoring power fluctuations using the electrical potential and noting the level of DC charge. Ripple and noise testing revealed that the rails are unconditionally power providing while maintaining a noise less than the standard mV rating for the v2.91 certification of the EPS.  The prodigious nature of a power supply is not told by just the sleek interior high quality makeup, the decorative exterior, and the various protective design assurances it seems to have. A brand new power supply, providing a better future for a PC, is told by its performance and reliability to which the Antec’s TruePower Quattro 1000W is a sage.

The Antec’s TruePower Quattro 1000W is worth the buy without a second praise, and anyone willing to spend quality money for quality value and trust of brand name should look no further than Antec and the Antec’s TruePower Quattro 1000W.

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:

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.

PC Power & Cooling has been around for quite some time. During that time they have developed a reputation of being a very high quality power supply company. With that high quality usually comes at a high price, and PC Power & Cooling has always been on the higher side of cost. Is it worth it? That is for you to decide, but read this review before you make your decision! Let’s look at the specifications of the Silencer 750.

Test Setup- Right To It

All tests were run using a fresh install of Windows XP Professional with SP2. For our stock speed tests, we ran everything at default timings for the CPU. Our stock speed testing used Corsair DDR2 C6400C4 2 GB kit at 2.0 vDimm at DDR2 800. Timings for our overclocking were left 4-4-4-12 and 2.0v. The video card was left at default timings as well for all tests. For this review, stability was determined by running our battery of tests, plus the ability to complete a 32MB test run. For our voltage readings at default settings, we ran everything at stock speeds, and DDR settings settings of DDR800 and 4-4-4-12, at 2.0v.

Conclusion

If you want the best components available you have to pay the price. If you want to take one of the biggest hindrances to overclocking success out of the picture, you have to pay for it. So, check out this PSU right now!

Today’s computer components are demanding more and more power in order to run at their full potential. Video cards and processors have advanced so fast in the last two years that their power requirements have barely been met by power supply manufacturers. This is still an issue today with SLi and Crossfire now in the mainstream. Consumers have to make a very tough decision when choosing which power supply to trust with their new system while keeping a close eye on the power specifications of each PSU to ensure they will get the stability they are looking for.

The Corsair PSU is aimed at enthusiasts purely. The power supply is a matte black and features red and black labels on the sides and back. Corsair is aiming this power supply at the high end enthusiast market and does not believe that incorporating LED lights and windows is where they should put their focus. Instead, they focus it on stability and raw power.

Opening the box up we found the power supply unit encased in a foam shipping housing and also inside was a modular cable bag, power cord, two plastic bags, and the owner’s manual. Opening up the cable bag we found 11 cables that can be used on the power supply.

The Cables:

• 2 – 800mm 4 pin peripheral power connector cables (Molex) with 3 “quick release” style connectors
• 2 – 450mm 4 pin peripheral power connector cables (Molex) with 2 “quick release” style connectors
• 2 – 550mm PCI Express cables
• 2 – 800mm SATA connector cables with 3 SATA connectors
• 1 – 600mm SATA connector cables with 2 SATA connectors
• 1 – Y-adapter cable with 2 floppy power connectors
• 1 – Y-adapter cable with 2 4 pin female (Molex) “FAN ONLY” power connectors

Corsair has shipped eleven modular cables with their power supply, but the unit itself can only use up to seven of those cables at any given time. Corsair has actually given us a greater number of cables that what is required, so we can pick at choose what to run per our system requirements. During our use of the power supply we didn’t run into any cable length issues when we test fitted the power supply into some common cases when we checked cable lengths. One thing that I noticed is that the power supply comes with the 24-pin main power connector, 4-pin +12V connector and 8-pin EPS12V connector that cannot be removed. For all of the systems that we tested on the 4-pin +12V connector was not needed, so we had to hide the wire in our case.

Overall the PSU is one great piece of hardware, and shouldn’t be missed out by anyone.
