Ok, so i've lowered my power supply category to some good cheap power supplies, and by the way you can get technical with me i'm not a newbie with computers and i have chosen good quality power supplies with good amperages on the +3.3V, +5V and the +12V Rail and could someone explain which rail provides power to what? . This is my Selection:
Corsair VX450W Power Supply
Antec EarthWatts 500W Power Supply
Thermaltake Purepower RX 500W Power Supply
OCZ 600W StealthXStream Power Supply
Antec Basiq Series BP550U Power supply <- (I'd rather not get this since it's a bit expensive )
Antec Basiq Series BP500U Power Supply
Right now i have my eyes on the Antec Basiq 500W Power supply since it's a bargain at only 45 Quid (Yes i have looked at reviews for it)
It has 36 Amps on the Dual 12V Rails (18 Amps Each) and 30 Amps on the +3.3V & +5V Rails so err help people
Get the one with the highest 12v rail rating in amps. The corsair may actually have the highest 12v rail rating, even with it's lower wattage. If you have more than one 12v rail, then add them together. For example, if 12v 1 has 18 amps, and 12v 2 has 16, then 34 amps would be your total. But a single high 12v amp rating is preferable when you're only using one video card.
Alright i'll try and go with a cheap Corsair Power supply but if i can't find any i have to get the Antec Basiq 500W, It has 11 more Amps on the 12V Rail than my current PSU , Still anymore reccomendations or can anyone choose between my selection?
That's the maximum per rail. Total is 34 amps. Go to nreegg where they show a picture of the label on the side of the PSU. Look at the second line where they show the maximum power - 408 watts (34 amps).
Obviously cannot be a total of 44 amps. 44 amp X 12 volts = 528 watts.
Of the PSU's listed, my first choice would be the 450 watt Corsair. second choice would be the Antec Earthwatts. I like most Antecs. I donot, however, like the Antec Basiqs. I think Antec cuts too many corners to hit their price points.
