VisionTek 800W Power Supply Review – A Great Thirst

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.

OCZ PowerStream 520 Pink Fondu

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.


  • OCZ PowerWhisper Technology
  • OCZ PowerFlex individually adjustable power rails with LED indicators
  • OCZ ConnectAll? Universal connector. (ATX, BTX, SATA, P4 and EPS12V)
  • ATX12V 2.01 (600w only)
  • OCZ PowerShield? power leads
  • ActivePFC (International version only)
  • 5 year warranty backed by OCZ’s exclusive PowerSwap? replacement program.


  • Frequency input 47-63Hz
  • Voltage Range 95-132VAC or 190-264VAC
  • Current Range 12A @ 115VAC or 6A @ 230VAC
  • Efficiency 63% max load
  • Noise <32dB
  • Mean Time Between Failure 140,000 hours

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.

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.


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!

Zerodba Review: Where Are You?

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.

  • Dual GPU Ready

The HX Series offers native support for dual graphic card configurations with two PCI-Express cables and high performance +12V rails. It is compatible with either nVidia’s SLI OR ATI’s Crossfire solution.

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.
