i was looking at the corsair 1200i and the XFX ProSeries 1000W 80+ platinum, but im not sure which one to get. the wattage amount doesnt matter, and i would like to custom sleeve all the cables, but that seems like it would be a little hard with the all black cable with the corsair 1200i...so...which one?
i plan on making a gaming/overclocking system. i just want to keep some headroom for upgrades in the future.
Ok, thats fair - just keep in mind what the ranges are here. A good quality 550-600w is plenty for crossfire. 700w is usually enough for three high end cards. Given increases in component efficiency, its actually pretty difficult to put together a new system that actually NEEDS 1000w. That said, people tend to buy a lot more than they need in the PSU space. That's certainly fine as long as you have a high enough quality unit that it doesn't waste power you aren't using.
You indicated you were looking at platinum models above -- I encourage you to focus on the platinum/gold -- quality is really more important than wattage, particularly if you are planning for the future/long term.
Comment: I have a strong personal bias for Seasonic and Seasonic manufactured units (they make a lot of the highest end PSUs for other companies).
