    Arrow Corsair HX750i Review

    Corsair comes to us today bearing a new and improved HX series power supply, the HX750i. Taking the old HX750, upping the efficiency to Platinum level, and adding Corsair Link support, this promises to be a welcome improvement and update to the Corsair power supply line.

    The Rosewill Fortress is on sale today for half the price $84.

    So I can't agree with

    The Bad:

    Platinum is really expensive at the 750W level... from any company
    PS
    Not saying all other factors are equal.(FULL MOD.,software etc.)
    Just that PLAT does not HAVE TO equal a 2x premium.

    I see $129.99 with a 20$ rebate. And it's a sale.


    So we still can't trust software readings? I mean it's not surprising, but ... still.

    I have found that my ASUS P9X79 Pro MoBo actually outputs pretty accurate software readings. Anyway.

    Seems like a good unit with reasonable pricing (at least when you want that platinum efficiency) to me. I don't suppose the semi-passive cooling is a potential problem here like in the RM series?

    To the extent you'd trust a dedicated measurement device built for only that very purpose? Nope.

    But that's the compromise... do you want an affordable power supply that measures sort of accurately, or one that measures very accurately but costs a small fortune?

    Still.. they're readings taken at the motherboard, so there's still that margin of error.

    What potential problem with the semi-passive cooling in the RM Series?

    Slightly questionable caps at pretty high temperatures on the secondary side (or am I mistaking something?)

    Yeah you missed the 20% off = -26$ + -20$ rebate = $84 DEL. AMIR

    Yes it is a sale, but the average price over the last month is $109...so still a reasonable price for a PLAT 750.

    My point was, and still is that the Prices from several sources(Rosewill, antec,etc. ) have come down significantly for PLAT units.

    Hence the statement that
    Platinum is really expensive at the 750W level... from any company
    is not true.

    More expensive than Gold? Yes. Really expensive?, No...the delta has decreased significantly compared to six months ago.

    Given that the HXi does not have the questionable caps you are referring to plus the ability to manually turn the fan on via software if you really don't like having the PSU in fanless mode I don't see any issues.

    The RM fan issue was fixed in a later revision. And as mentioned, this is a PSU in a very different league. The caps can take a beating.
