Advantages: Modular power connectors, good design, solid build, designed in the UK. Disadvantages: Large
for the powersupply[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 to ...
Advantages: Very cheap, 2 fans Disadvantages: None
Arguably the most important component inside your PC is its powersupply, the powersupply unit (PSU) provides the power to every other component inside your computer ie: Motherboard, hard drive, processor, graphics card etc etc... and all these components require a powerful and extremely stable PSU in order to operate as intended.
14 months ago i built my current PC and opted to use the Q-tec 550 watt dual fan gold as its powersupply unit, most modern day PC powersupplies average around 350 watt and they are predominantly fine for most PC's but as you add extra components to your PC like extra hard drives, or a faster processor or faster graphics card then you may get close to reaching the limit of your particular powersupply which can result in either the PSU not functioning properly (causing serious system instability) or in ...
Advantages: Stable, cool and quiet, modular cabling, overall quality, more powerful than official rating Disadvantages: cables a little stiff
First off, I'm amazed that I am the first to review theis product. It's one of the best PSUs on the market. Corsair are well known for their excellent RAM, but their forray into the realm of powersupplies has been immensly successful; the HX620W is consistently rated as one of the best enthusiast models on sale.
Corsair markets the 620's modular design, industrial-grade capacitors and quiet running, as well as its capability for supporting SLI. These are indeed excelent features; the supplied cables and their modular system makes keeping your case clutter-free amazingly easy, and installation in general is just far too simple to be true! The PSU also runs very cool, and very quiet as well - the 120mm fan keeps the unit at a reasonable temperature, while making absolutely no sound.
Those 'industrial-grade' capacitors aren't just ...
