the 500w psu in the link will be more than enough... for this system 400w wold be plenty but theres nothing wrong with leaving some headroom for upgrades in the future.
as for roswell. i dont know if their a good manufacturer... never used them, never heard of them so wouldnt get one.
go for one around 400w or above from a reputable manufacturer. crosshair and seasonic are my personal favorites and im sure other people here would be happy to recommend good manufacturers.
tier 1, 2 and most of tier 3 from the post above are what i would call good models and theyre what u should be aiming for if u want your psu to last and have stable output voltages (cheaper models can fluctuate by up to 2 volts causing unexplained crashes and instability).
if some one is going to tell you a good quality 400w psu is not enough for this set up they havnt done their homework
so this would be a better psu than the on in my link this is stilla 500 wat but it was on that like u gave me for tier3. this will still fit my budget. Im just on a tight budget, This psu leaves me with money in cents lo
K since starting a new thread over my question is silly,so my apologies for asking it here I already own a UMAX 450W psu for this config:
Intel E4300 1.8ghz C2D, Intel G965ryck mobo, 1GB trancsend ram 800MHZ ddr2,no graphic card.I plan on getting 3850 in 4-5 months. I know this wattage should be enough but since tiers are so important,how do i check what tier my psu belongs to. Any links or is it written on the psu itself?? Thx!!
the "tier" isn't set in stone, it's based mostly on popular opinion. the link above is a sticky on another website. the psu section here has one too. if your psu isn't on the list, it might still be good, but its not a well known quality psu.
