Introduction

When Corsair first diversified into the PSU market back in 2006 with the release of the HX520W and HX620W, it is likely that not even they could predict that in 2015 their company would be one of the most active players in this segment of the market. After all, Corsair's primary focus at the time was memory-related products, with the company having seemingly zero experience on power supplies. At that point, it would be extremely difficult to project that nearly nine years later Corsair would be one of the most reputable PSU brand names and would be offering dozens of products through eight different PSU series.

The people over at corsair did not limit themselves to releasing new models and series – they kept upgrading their old models as well. Today we are going to have a look at a unit from the latest revision of their HXi series, the HX750i. The HX series is of special significance to the company as it was their first PSU series. Much has changed since the first units that could barely get to 80% efficiency and had mediocre power output; the HXi series now ranges from 750 to 1000 Watts and are fully modular, digital units with an 80 Plus Platinum certification. That makes the HX750i the least powerful unit of the series and, with a retail price of $170, the least expensive one as well.

TOTAL 750W

Packaging and Bundle

We received the Corsair HX750i in a relatively large cardboard box. The company opted for a straightforward, clean artwork theme for their enthusiast-grade PSU, which is mainly focused on a picture of the unit itself. The front of the box lists the most important features of the power supply, with additional details on its sides and back.

Despite the class of the power supply, the bundle is rather spartan. Corsair only includes the necessary AC power cable, four black screws, a few small cable ties, and a case sticker. There are no cable straps, thumbscrews, or any extra accessories included with the HX750i.

Every cable of the HX750i is detachable, including the 24-pin ATX cable. Corsair uses flat, ribbon-type cables with black wires everywhere, with the sole exception being the internal USB Corsair Link cable that is a typical USB cable with round black insulation.

    Isn't the fan FDB, not rifle bearing? Reply

    It is FDB according to the jonnyGURU review in August.

    While Anandtech has a well-deserved reputation for quality reviews, with about 300 reviewed power supplies since 2007 I'll trust OklahomaWolf.

    Yep, OklahomaWolf or nothing else when it comes to PSU reviews. Bobnova isn't half bad either. Reply

    That being said, Corsair usually ranks from excellent to near perfect for their higher end PSUs like this one. Reply

    TPU is quite good as well. I'd say OklahomaWolf and crmaris are two of the top PSU reviewers out there. Reply

    So, let me get this straight: a. B/c Johnny Guru tested a similar PSU that had an FDB fan and not rifle bearing fan, this review is bad? b. Even if the fan is FDB (wtf is that anyway) and not rifle bearing, how exactly is this the best realization that ever dawned on humanity after penicillin?

    I really don't want some of whatever you are smokin'.

    Because jonnyGURU tested this exact power supply model - and it's 1000W brother - and determined that this had an FDB fan, this review is incorrect in at least one simple area.

    You'll note that nobody in the replies -- other than you -- said this review is bad, or that not being able to identify a fluid-dynamic bearing over a rifle bearing is important in the history of humanity.

    The comments offered opinions on what reviewers do such a good job that they set the standard by which all other PSU reviews are measured. If you have an alternative with equal or greater demonstrated competence, I'm sure the people reading this power supply review would love to have another trustworthy reviewer to consult.

    Bah, typos. Really wish we had an edit button. It's/Its, etc. Reply

    It looks very similar to the rifle bearing in the RM series, but it's a higher-end FDB bearing like the AX1500i. Reply
  • jonnyGURU - Friday, January 16, 2015 - link

    It's an FDB fan. NOT a rifle bearing. This is stated on Corsair's website and the reviewer's guide included with the press kit. Also, the part number on the fan is different than the rifle bearing used in the RM Series. Reply
