Power Supply Upgrade?

I've got a XFX PRO 650W PSU. I'm looking for a modular power supply of the same/a little more wattage and price. What are some options?

    The gravy train keeps on rolling for EVGA today with the G2 750W. Expectations were high, and EVGA rose to them without breaking a sweat. I have to imagine that over at EVGA headquarters, they have to regularly take breaks to go up on the roof and yell, "Top o' the world, Ma!" I certainly couldn't blame them. Now all we need from EVGA is their answer to the Corsair AX1500i, and we'll be all set.

    The Good:

    excellent voltage regulation
    less than 15mV ripple on the outputs
    switchable semi-fanless mode
    excellent build quality
    10 year warranty
    competitive price

    The Bad:

    nothing

    The Mediocre:

    10 year warranty requires registration first



    Performance (40% of the final score) - 10. I mean, really... were you expecting any other score in this category today? Beyond excellent ripple suppression, beyond excellent voltage regulation, easy pass for Gold efficiency both times. I mean, come on... if anything deserves a perfect score here it's this unit.

    Functionality (20% of the final score) - and it's getting another 10 here, as well. We have a fully modular unit with very nice black sleeved cables. The manual's decent. There are lots of connectors. There's a switchable fanless mode. EVGA gave us a little test adapter to see if it works before we use it. There are lots of other goodies in the box. Can you find something to complain about here? I certainly can't.

    Value (20% of the final score) - Newegg's offering this unit for $129.99 right now, with a rebate on top of that. I can't score on rebates, but I can drool all over that price. It's directly competing with the Thermaltake Toughpower Grand, which may or may not still be the same one I reviewed. That said, the real competition is from Seasonic. Their KM3 750W is ten dollars more money. And you'd probably think EVGA has this all sewn up based on that alone. But... XFX has a Seasonic built unit at this same price point, so this category is not a lock like we saw with the 850W model. I'm going to go with a 9.5 here. When a Seasonic build is your only competition, you're doing it right. In fact, I'm almost ready to say that it is Seasonic who is competing with this one than the other way around.

    Build Quality (20% of the final score) - as was the case with the 850W, I still want to see that fan control switch wiring cleaned up some. There's a little more glue on it this time holding it to the modular board insulation, but it still looks rather like an afterthought. There's room for that switch directly on the back panel... how about we do that instead, Super Flower? 9.5.

    Or the BEST 850W on the planet.

    Performance (40% of the final score) - we're down to scoring time again. And, as with all other recent units from EVGA and Super Flower, this one will be a breeze to score. Pass for Gold, both cold and hot, means no points removed from a perfect score. Amazing ripple suppression the likes of which has only been seen a handful of times on this site means no points removed there. And finally, yes, this unit did manage to hold onto an average of 1.2% regulation in the hot box so no points come off there, either. This guy's getting a 10.

    Functionality (20% of the final score) - full modularity. Lots of cables. Good cable lengths. Plenty of connectors. Switchable semi-fanless mode. Lots of goodies in the box. Nice size 16 gauge line cord. I really can't think of anything to complain about here, either. 10.

    Value (20% of the final score) - $144.99 is the asking price of these at Newegg right about now. It shares this price with the Silverstone ST85F-GS. Now, about the only thing that unit has on this one is its much shallower depth. Other competition? What other competition? Coolmax? More money, if you can believe that. Corsair HX850? More money. Corsair RM850? More money. Themaltake Toughpower Grand? More money. Seasonic X-850 KM3? Way more money. EVGA has this category locked right down. 10.

    Build Quality (20% of the final score) - I'm going to remove a point for the fan control wiring and be done with it on this one. Soldering is good enough to pass with no deductions, the AC line filter is pretty much all there in the end, the component selections are fantastic, and the capacitors are wall to wall Japanese. 9.5.
