OCZ GameXStream 1010-watt Power Supply

Over the past few years OCZ has proven itself to be a company that has a tremendous impact on the PC Enthusiast market segment by offering cutting-edge products that provide best of class performance and technology. It’s no wonder then how a company like OCZ can offer its latest 1010-watt power supply at pricing that’s ultra competitive and offers excellent power for just about any hardware scenario you can throw its way.
While most of us in the hardware business often lament over the more “sexy” products such as CPUs and GPUs it doesn’t mean that we should – for a second – forget about the very backbone of what keeps the PC humming along – the power supply. Its chore is a thankless job that so easily is taken for granted; however is ultra crucial to the overall performance and stability of ones PC experience.

Budget PSU Roundup with HardwareCanuck - part 2 !!

Well, here we are in what seems to be an almost weekly occurrence: another power supply roundup by yours truly. This time we will be looking at a little more powerful models than we were last time; 500W to 600W models that all come in at under $105. Sounds like a great deal doesn’t it?
In this day and age we are faced with ever increasing power demands from higher-end components such as Nvidia’s 8800-series and AMD’s almost-mythical R600 cards. To power these beasts (or at least the 8800-series because of AMD’s tight lips about their card) and a proper processor, consumers should be looking at a minimum of a 450W power supply. If you start adding more than one hard drive and perhaps some overclocking, you are suddenly faced with the purchase of a 500W or more power supply. While this proposition can make some people weak in the knees (and bladders) there are relatively cheap 500W and above power supplies out there. It is in exactly these situations where the PSUs in this roundup come into play.

This test includes:
FSP Blue Storm II 500W

Cooler Master Extreme Power Duo 600W

Nmedia MP-500 (500W)

Enermax FMAII 535W

Silverstone ST50EF-PLUS (500W)

Mushkin HP-550 (550W)


This is the one test that made these power supplies crap their pants and call for mommy; 8800GTS cards in SLI ( as shown on this picture)

Enermax Galaxy DXX Series PSU

Today we are going to be looking at Enermax's current top tier unit the revised Enermax Galaxy, now called the Enermax Galaxy DXX (EGX1000EWL-01). This power supply was originally released as the Enermax Galaxy 1000w but has recently been revised to include an 8pin PCI-E adapter to support newer video cards that draw up to 300w of power. In addition to the 8 pin PCI-Express adapter modification we will see if Enermax has changed anything "under the hood" on the Galaxy DXX.
The Galaxy DXX is an interesting power supply in the way of our evaluations as most power supplies we have reviewed to date have at least paid lip service to the various iterations of the ATX specifications. The Galaxy DXX however, is designed to more closely follow the EPS/SSI design guide.

Design for the hard-core gamers that demand nothing less then perfect.

The Galaxy DXX is equipped to handle dual 300w video cards thanks to the new PCI E 2.0 standard. Enough juice to handle the meanest dual quad core CPU system and quad graphics card on the market today.

Eight-Pin PCIe GPU connector updated

THE WORD AROUND CeBIT was that there is a problem with the new proposed eight-pin PCIe adapter we first told you about in January.
It seems that you could force the mobo eight-pin power lead into the PCIe one, or maybe it was the other way around.

Budget PSU Roundup with HardwareCanuck

Well here we are on my first PSU review here or anywhere else for that matter and this one is going to be a big one. This roundup will focus on four budget-minded power supplies which range in price from $45 to $75 with one power supply being included in the price of a $120 case. I will give all these units a thorough going-over and put them through a battery of tests. I suggest you read this whole review as in many places I will refer to performance differences between the units. You should also know that these are all on an even playing field as they were all purchased by me so I do not want ANY of them to fail.

Just my quick comment that this review is good because it includes two EVGA 7900GTO cards in test! So you can see how much quality and reputation of PSU is important in setting up SLI comp. So here it goes Sparkle, Nmedia, Enhance and Antec go head to head....

8-way SLI and Crossfire Power Supply (PSU) Roundup

This article is a bit older, about 9 months. But it's definately worth readin so you could decide which quality PSU you should buy to hav enough power for your SLI configuration.

When NVIDIA and ATI started certifying power supplies to work on their SLI and Crossfire gaming platforms a number of problems instantly popped up. The first issue was that ATI and NVIDIA only tested power supplies submitted to them, resulting in their list of approved power supplies being small. The second issue is that both companies test their certified power supplies on a ?current system?, not a high end platform running wide open on all cylinders.
A number of weeks ago a number of system integrators contacted Legit Reviews looking for stable power supplies to power their top end gaming systems. It turns out their systems were not working right with ?approved? power supplies and they turned to us looking for an answer to their problem. We then contacted Aerocool, Antec, Mushkin, OCZ Technology, and Thermaltake for SLI/Crossfire power supplies to see which ones could hang in our test systems.

Purepower Express 250W

With each new generation of high-end video cards the demand for power just keeps growing. Not only does the separate video cards need more power, using two in SLI or Crossfire mode increases the power demand even more. It is of course possible to just buy a new more powerful PSU every time you upgrade but that is not always practical, especially if you have a PSU that you are happy with and do not want to have to replace.

With the release of the GeForce 8 cards from NVIDIA and R600 from AMD we also have another problem. While two PCI-Express power cables were enough to power two previous generation video cards in SLI or Crossfire, we now need 4(!) cables if we happen to be able to afford a second GeForce 8800GTX or R600.

Ultimate Overclocked PC only needs 500W power supply

First INQpressions Overclocked Kentsfield, Nforce 680i, dual Nvidia 8800GTX SLI, Evercool water cooler
UNTIL AMD'S QuadFather is out in numbers (and, for many apps, even after that), Intel Kentsfield or officially, Core 2 Extreme QX6700, rules the roost in the PC desktop space. Combine it with the performance driven Nvidia Nforce 680i based mainboard and dual 8800GTX cards running in SLI, say 2GB of Corsair, OCZ or Geil low-latency high bandwidth memory at DDR2 1066 levels, add the usual hard disks, DVD and, well, cool the CPU with some watery stuff so that it doesn't get really hot when fragging enemy soldiers or compressing those HD DVDs and you have the ultimate Xmas 2006 PC present.
