I didn't say that I liked the Xion brand, just that 1000w would be better than a 750w. Will a 750w psu work? I already responded in a previous post that I use a TP New 750w in my SLI rig successfully. OP's choice. Do you want our recommendations on brand or between the OCZ and Xion?

Also, the 80+ ratings do support the highest efficiencies at the 50% level

Sorry that isn't what I meant, I was talking about getting an overkill PSU. Since we are talking about what he could pull at load, if he went with some overkill PSU he would end up in the 15-20% level the majority of the time with everything unloaded.

Sure i would love to hear what you think on which psu/brand is better... Im sure the 750w ocz will work. The most load i put on this system is gaming sometimes hours at a time non stop... my worry is if there is risk of damaging my components using the 750w.. and is there a way to tell once im running sli if im getting enough power.. Mainly worried i have invested alot of cash in this system and don't want to risk harming it. at the same time wat to make sure i get best performance... thanks and i apologize if i'm driving you nuts.. making the decision soon so any further input helps

Gotcha My "fur" wasn't up I guess I just like to have the spare power for future upgrades instead of buying a new psu. It's nice to see that the 80+ ratings are in effect for the low end too (20% level)

Bother us?!?! Not at all! We're glad to help a fellow OCN'er. I (still) think that 750w is fine and I would have to recommend the Antec True Power New 750w psu. Check out the JonnyGuru review of this supply. It's under rated meaning that it will handle loads greater than 750w and it has great regulation and efficiency. here is the review.

Another that I can recommend is the Seasonic X-series, a 80+ Gold rated psu that also scored high marks with JonnyGuru. I don't have one rated that high but I run a 660w and a 400w X-series and love them. I think Newegg has a deal on the 750w as we speak.

One more choice might be the XFX psu's. I've seen them recommended as having Seasonic internals and a good bargain.

I think all of these are at or near the $100 level

^This, right now the Seasonic X750 is $120 with the promo code on the egg.

I just picked mine up and had the same doubts, but was told that the seasonic could likely power 2 580s. Let me just try and find the thread....

Good to look on reviews. Sadly, I haven't found any qualified review of the thread starter's xion 1kw psu, but considering its price tag should be good.

As far for oversized psu's, I've seen excellent reviews on johnnyguru... If I remember well I seen a passive 400w capable of doing something like 550w with ease that was crazy.

Going back IT, never seen much ocz power supplies... better go antec like the one linked by Hollywood406 , or any other brands we have good reviews of.
