Cisco Enhanced AC Power Supply - power supply - hot-plug / redundant - 8.7 kW

Advantages: Modular power connectors, good design, solid build, designed in the UK.
Disadvantages: Large

...for the power supply[1]. ATX 2.2 includes changes to the main power connector (20pin to 24pin), removed auxiliary power connector and includes a need for a 3.3v tolerance. Effectively ATX2.2 is a a new standard variant based on older designs looking to power newer technologies but also to provide increased power modulation and better tolerances to power deviation. Intel BTX, another form factor standard that talks about heat sinks, finalised about a year ago. From the point of view of the consumer it makes it harder to have a very small case that complies to all specifications however it should also improve tolerance to heat substantially. From the point of view of the manufacturer it is difficult as it means doing some simple redesigns. SLi (Scalable Link interface), this is the interesting specification that's going to take some time... Read review

Advantages: Stable Voltage for all components
Disadvantages: Exspensive

...OK ok ok the power supply does have a limit, but to be fair...very few people shall ever take it to that stage. If anyone out there is having Problems with their PC and need to find a better PSU?..Then look no further than this! The Antec TruePower 550W is the Best PC POWER SUPPLY money can buy at the moment. It will give stable voltages all the time, and this can be seen via the graphic cards software, and also in The BIOS of some computers. The fan is controlled by a thermostat within the PSU, so obviously if the psu is cold the cooling fans will spin slow, and if the PSU starts to rise in temperature the fans pick up speed to improve the cooling within the unit. All connectors are black, and the main power cable for the Motherboard is Braided with a black Netting (24Pin). Though the Unit has a steep price so beware but if u... Read review

Advantages: Pro: Slinky, power-packed server for cramped datacentres.
Disadvantages: Con: No 64-bit PCI slots, not enough PCI expansion slots.

...drives, a slower bus and older 500MHz Pentium III processors. Inside the casing everything looks easy to swap out. The top covers fold out to allow easy access to the interior. The two redundant hot-plug power supplies are a doddle to pull out quickly if needed. The hard drives are hot-swappable too, but a metal lock will stop anyone pulling out a disk drive accidentally. The chassis weighs in at 22.7kg and has a 2U rack height with a depth of 66.6cm, this is important for IT managers looking to pack as much processing power and storage space in a cramped datacentre or server room. The memory modules could prove finicky to remove if you have big fingers and cabling got in the way when trying to take out the fan. However, setting up the server was nice and quick with the minimum amount of fuss. The PowerEdge 2450 is the first in its... Read review
