OK after seeing so much (bad in my opinion) over PSU's i thought i'd ask other members what they think.
In my opinion there are 3 things you should look for in a PSU.
1 - Manufacturer # you need to get a PSU with a recognized name or from a decent OEM manufacturer. If you can get a 80% efficiency one even better as it'll lead to less heat in the system and lower energy bills, but it isn't essential
2 - Amount of rails # If you can get a PSU with a single 12v rail, at most you ant 2 rails. the only time you should get a psu with 4 rails is if it's rated over 1000w.
This is just common sense. say you buy a 550 w psu with 2 rails, you'll probably get 200w on each rail so you could run a single high powered graphic card on each rail, and what is left over is wasted.
If you just get a 450w power supply with a single (1) rail, you will be getting somewhere around 350w on that rail, allowing you to share all that wattage over maybe 3 high powered graphics cards. I guess this isn;t a given, as there are some graphics cards that will use in excess of 150w, but at the least you'd be able to run 2 graphics cards - the same as the 2 rail psu
3 - Total wattage # You need to think about how much power your computer really needs, and then buy a PSU maybe 200w over that value to allow for future upgrades.
I don't understand why people are giving advice to other members to buy 750w PSU's when the person's rig would only use 400w max. They don't even consider the other aspects you have to consider when buying a PSU.
My rig uses a 550w (max rated) PSU with 2 rails, i can get about 175w off each ao i can run the mainboard/cpu on 1 rail, and my 4850 on the other. The amount of times i've been told i should upgrade my PSU is unbelievable. I don;t see any reason to upgrade until i go xfire.
(btw AcBel is an oem manufacturer that produce psu's for Coolermaster)
"In the real world, very high PSU ratings are seldom important. If you're not running giant drive arrays, big Peltier cooling rigs and/or an amazingly overclocked CPU, a quality 350W PSU should be more than enough for any system. Extra capacity doesn't hurt, though; a computer that only needs a 300W PSU won't draw any more power if you give it a 600W one." - Inside your PSU http://www.dansdata.com/psus.htm
