XFX is a company that we've always found to never mess around. All of the products that they offer are well respected amongst enthusiasts. While they are most notable for their overclocked video cards that run rock solid, they have quite a few accessories for enthusiasts, on top of their power supplies. They even have some cases coming soon, which look rather promising. Sorry to get your hopes up, but we aren't looking at one of their unreleased cases just yet, but rather one of their new XTR power supplies.
The new XTR series is available in three wattages; 550W, 650W, and 750W. Today we are taking a look at the 550W model. The series features 80 PLUS Gold efficiency, and fully modular cabling. On top of that, XFX has incorporated their hybrid fan technology, which allows the user to select whether the fan is always-on, or doesn't kick on until a preset temperature or load is reached. XFX doesn't compromise on their quality no matter what, and judging by the outside of the box, the XTR 550W is no exception; even despite the low price tag on this unit. However, looks can be deceiving, so let's rip into this thing and find out what it is made of.
Specifications, Availability and Pricing
The XFX XTR 550W features a single 12V rail that is rated for 45A of power, or 540W. The 3.3V and 5V minor rails are each rated for 20A, with a combined maximum output of 100W. The 5VSB rail is rated for 2.5A, or 12.5W. Maximum combined output for the XFX XTR 550W power supply is 550W.
As I said before: XFX doesn't compromise on quality, at least not that I have ever seen. They include all the features that you could really want in a power supply. As far as protections are concerned, SCP, OVP, OCP, OPP, and OTP are all present. The XFX XTR 550W is rated for 80 PLUS Gold efficiency. The unit features fully modular cables. All of the cables are of the flat ribbon type, with the exception of the 24-pin main, which is fully sleeved with nylon mesh. XFX does in fact rate the XTR 550W for 100% continuous output at 50C.
The XFX XTR 550W power supply has an MSRP of $89.99 at the time of writing. This is a great price, and it puts the unit in the low to mid price section of 500W-600W units. There might be others available that promise better efficiency, but you will hard pressed to find one that is comparable, and fully modular, in that price range. Price hunting won't do you much good, as it the XTR isn't widely available right now, but XFX is working on that. NCIX will save you a few bucks at of the time of writing this article, as they have it $10 off. Once that expires, it won't matter where you get it from, and XFX will back it with a five-year warranty.
