I will be using my previous:
22" LCD Dell Monitor
Radeon HD4650 512mb (Until the GPU price drops, hopefully in the next couple of months, then HD 5770)
Keyboard Logitech Wave
Seagate 500GB SATA2 7200rpm 32MB cache (until I can get the SSD of my dreams)
Mouse, speakers, etc.
No DVD or floppy drives.
I have been roaming this great site (and others) for information for the last couple of years, and have read all of the stickies and many threads on new builds and many other subjects.
the 620 is good but there has been a 650 watt revision of in in the form of the hx650
a good psu is a good psu irrespective of how many rails it has
you might wanna look into the antec earthwatts 650 it tends to be round the same price as the vx 550
the best 650 watt unit on the market is the seasonic X650 if you want the best
but other then that either one should be good depending on how high spec graphics card you gonna get or if you planning on dual graphics card in future
500 watts is more then sufficient to power any single graphics card,650 watts to 750 watts for dual cards the newer ati 5 series dont need a lot of power Ati reccommends 600 watts for dual 5 series but as said depends on how high you gonna go with your graphics cards
Thanks for the reply,
Will be using a single card, my MOBO has limited channels, if USB3 and SATA 6GB comes out I'd like to use them.
I'm from the US but living overseas now, my brother is burning in the MOBO, CPU and RAM, then will send it to me. Couldn't find a reasonable P55 board here.
I'm limited to what I can get locally, haven't found any seasonic here yet, I have looked. Can get Corsair, Antec and lots of not recognizable brands.
Was planning on 550w, but will get 650w for a safety margin.
Won't worry about the rails.
