i'm doing a build... i've already reached my budget with everything i want (i5 2500k, 560 2gb gpu..etc). looking at the usually overlooked power supply. i dont plan on SLI'ing anytime soon but want to leave that option open for the future (upgrade).
they have an 850 xtremegear sli/xfire compatible defaulted. however, for $50 more i can change it to a Corsair CMPSU-750TXV2 750W 80 Plus Power Supply - Quad SLI Ready.
obviously its 100W less, not sure its a needed 100W, but nevertheless does the gains outweight the loss of 100W??
If you are going to go that route and not build a pc yourself save yourself some dough.
What other psu choices are offered?
A 500W psu will power your present specs.
I'd buy the lowest power good quality unit offered.
If everything costs more then the default unit = stick with it.
It cheaper and quite easy to replace a psu later on if you decide to SLI.
Just had a look a generic 500W is the default unit.
Buy something decent later on from NCIX or Newegg.
