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: Seems reliable, nice looking and cheap Disadvantages: i have heard a few to many bad reports about this PSU
and fitting which matches the universal fittings inside a PC case. A few screws and its done! (easy now ;o) lol)
The cables are a simple affair as they will only plug in one way so you cant go far wrong, and your component instruction manuals will also help guide you to what supply plug they will need... Think of a really simple jigsaw puzzle and you've got the right idea.
Then it was a case of plugging in and turning on ( see my PC case review lol)
This PSU has served me well with no trouble as far as i know although i have had some Graphic card problems, which i cant get to the bottom of, and one of the few ideas i have left are powersupply problems. I think the wattage of 450W should be ample for my current machine, but this is where im not sure how well this PSU performs. I have read many reviews of the Q-Tec range and many of them ...
