  1. Performance (40% of the final score) - and so it comes down to the scoring. I'll get the obvious out of the way first, the voltage regulation. No deduction there requires 1% or better average regulation these days. This unit, rounded off, did 3% in the hot box. Strictly average. So, I'm taking a full point off, there. Were it not for that outstanding 5V rail, it would have score significantly worse, believe me. But I'm not done yet, no sir. On to the ripple. Again, a zero point deduction requires 25mV or less at full power. This unit did closer to 70mV, which is good for another full point off. Also, we had the minor rails both hitting close to the spec as well. On those, a zero point deduction requires less than half spec. Half a point each comes off. And I do believe I'm stopping there. We hit the Bronze efficiency target both times, so there are no points to come off there. Overall... yeah. Average voltage regulation, about average ripple control (unless you crossload it, then look out), and exceptional efficiency at low loads. I gotta admit, I did like the efficiency profile this unit had. Otherwise, I'm moving to the next category on the back of a 7.

    Functionality (20% of the final score) - ok, here's how it goes for this category. Not fully modular, so half a point comes off. Not even semi modular, so a further half point comes off. That's just how we roll here at the site these days. Modular isn't the cost barrier it used to be, so it has to count for something in the functionality score. Now, to this, I'm going to remove another point for incomplete sleeving. There's just no reason to get half the cables done, then leave the other half alone. But, I do believe I'm stopping there. Were this not the budget unit that it is, I'd be a little miffed at not finding any cable ties inside, but I'll let that go this time because of that one chain of SATAs with the short cables between connectors. 8.

    Value (20% of the final score) - this unit is currently going for $84.99 at Newegg, with a few of Newegg's competitors offering it for a dollar or two less. You know, that's not half bad for a 750W unit, even one as average in every way as this one is. That said, Kingwin has not one but two models at 850W and 1050W sitting there at Newegg for the same money. These are, frankly, based on superior Superflower platforms. But then again, neither one is as small physically as this unit. And then you've got the Antec Truepower New 750W sitting there for only five bucks more money. Traditionally, FSP has been the absolute king of decent power supplies for not much money. But this time, I think they're pushing the wheel uphill. 7.5.

    Build Quality (20% of the final score) - I have no real complaints, here. Soldering may not look that impressive on this unit at first glance, but keep this in mind - I could not remove that heatsink by the transformer with my iron. It just did not get hot enough. FSP somehow got that soldered down perfectly without ruining the rest of the PCB. I'm going to pull out a 9.5 here and you can't stop me.

    The Raider 750 watt unit is FSP's latest attempt to keep their reputation intact as a budget segment leader in the market. And for the most part, it doesn't do too badly at the task. But, I have to wonder if they aren't perhaps trying to come up with innovative designs at the cost of performance, here. 12V regulation was one small step short of being truly mediocre, and the 3.3V rail didn't do much better. Yes, the 5V rail really shone, but how important is that rail anymore, and how useful is that performance if the unit's group design can't take being crossloaded? This unit does indeed have a place in the market. If you're spending most of your time rocking flash games online with the occasional gaming session on one or two low powered cards, you could do worse. But you could also do so much better for just a bit more money. I really think the price needs to come down even more than the cheapest price I can find on this today. Once it gets into the $70-75 range, then I think it becomes a better value.

    The Good:

    excellent low load efficiency
    shallow mounting depth
    matte black goodness
    exceptional 5V stability
    50mm intermediary cable lengths on one chain of SATAs

    The Bad:

    a little on the pricey side for the performance gained
    below average 12V regulation

    The Mediocre:

    serious 5V ripple issues when crossloaded toward either 5V or 12V - just don't try it with this unit

    GeForce GTX 670 - On your average system the card requires you to have a 500~550 Watt power supply unit.
    GeForce GTX 670 2x SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
    GeForce GTX 670 3x SLI - On your average system the cards require you to have a 850 Watt power supply unit as minimum.

    Remember, if you are going to overclock the GPUs or processor, then we do recommend you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively. Source: http://www.guru3d.com/articles_pages/geforce_gtx_670_2_and_3way_sli_review,4.html
