XFX P1-550B-BEFX 550w XTR Gold Fully Modular Power Supply Unit

Still working perfectly after a year (bought May 2015)Fully Modular means you no cables attached, only plug in the ones you require. This XTR series is made by Seasonic.Nicely boxed, securely wrapped and foam enclosed PSU unit, with a separate box within for the plentiful cables, User Manual and came with a 3-Pin UK Plug. The cables are not fancily sleeved but a decent no-thrills sleek black,Its very silent at 16dBA but if even the quiet fan airflow is an issue, there is also a 'Hybrid Fan Control switch' (located where you plug the modular cables in) which enables passive cooling i.e. fan off when not required and auto turns on when it gets to a certain temperature (20% Load or 25°C), which due to its location and labeling, cannot be confused wit h the Power switch at its regular locale where the mains power cable plugs in.Would have liked to see the images / more illustrative features stated in product description, so posted those of the box here too for those like-minded.

A good PSU. The item is currently under review because it was delivered with an American 2 pin plug. Not an issue if you have a spare UK one, however may impact any warranty claim. Easy to fit the modular cables, space saved by only using the ones needed. Clever hybrid fan that is linked to power usage. *important* after fitting and switching on at the rear of the unit, wait at least 5 seconds before attempting to switch on the PC, there appears to be some sort of delay, as if the unit is either calibrating itself or checking your system. This took me by surprise and made me think I had a duff unit. *further update* after several weeks of using, I am impressed with the quality of this unit. The hybrid fan switch keeps it very quiet, the lack of UK plug was easily rectified, and the modular cables are so much better than having to find room for unused ones.

The unit which was delivered initially turned out to be faulty (I got no power out of it), which was disappointing as this has great reviews on other sites. However, since Amazon were fantastic about sending me a replacement, I won't let that affect my rating.Pros:- Delivers power to my newly built PC perfectly- Fully modular- 80+ Gold rating- Not too loudCons:- Some of the cables are a bit short- The 24-pin motherboard connector cable isn't very flexible

What is there to say? I bought this because I knew it was a Seasonic build and therefore very good quality. Lovely packaging and a great range of cables, (all black strip cabling) and it seems to work like a dream. Quiet and absolutely no problems; I have full confidence in the product, and look forward to it providing power to this build and many others.On a technical note, there are no instructions to speak of, but since all the cabling is clearly six/eight pin, it can only go into certain connectors. And it certainly looks the part. Also, it's a heavy blighter, but to me that usually speaks of quality, so I'm not complaining at all...Very happy.

This review is for the XFX 850W XTS/PRO Series fully modular PSU with model number P1-850B-BEFX. Note that there is some confusion with XFX naming as if you look for reviews you will notice there is another 850W PRO PSU by XFX that looks different and is also not the same inside (and is 80 Plus Bronze, not Gold). The current official naming is XTR 850W Gold and this is what I got so even if the naming has changed the product number P1-850B-BEFX is what matters and is indeed correct. So what was 850W Pro Black Series Gold is now 850W XTS Gold, but it is the same product.Main features:• 850W real wattage, also rated at 50C.• 80 Plus Gold certification (efficiency up to 90%).• 105C rated capacitors (some Japanese, some not).• Fully modular.• Single rail Seasonic design, 5 year manufacturer warranty.• Hybrid fan control mode, 120mm fan.Last year I was looking to upgrade my aging CM 600M half modular power supply with something a bit more powerful and especially with a better efficiency. 80 Plus Gold was a good fit as Platinum is still much more expensive and I also wanted to go fully modular this time. I needed PSU design with a good track of reliability. So in the end somehow I spotted this XFX power supply and started researching the Internet for reviews. As mentioned there is a bit of confusion and change of naming of the XFX PSUs, but in the end I found a review of the right model based on the product number. So all the requirements were in check with the added bonus of hybrid fan mode which if enabled (there is a physical switch on the PSU itself) only turns on the FAN when it is really required so at low loads it stays off. These low loads are for example when the PC system stays at idle, mine stays around 120W usually on the power wall. That is on a Intel Skylake i5-6600k with Gigabyte Z170-Gaming G1, 16GB 3000MhZ DDR4, Radeon 6950, 3x HDD, 2x SSD and 5-6 fans in the box.So looking at the reviews it was great to see that at typical loads of around 150-200W at the wall efficiency is around 90% which is great as this is what matters for me the most, in fact I am not really gamer so low load efficiency is really important for my use.I am using this PSU for a bit less than a year, but it was great so far. I am mostly browsing the Internet so load generally stays low which means that the PSU is as silent as possible, because the FAN is mostly off thanks to the hybrid mode. I also believe some people experienced high pitched noise coming from the PSU, but that was not the case with me. It was also very important to me that this power supply is also efficient at low loads as this is my typical use… which means that I don’t really need 850W, but doesn’t matter as Amazon had a great price back then so it was an easy choice for me. So in the end you get a Gold certified psu with a proved Seasonic design with 5 year warranty, fully modular with hybrid fan mode… the only way up is to get Platinum and Titanium certified PSU, but then the price goes way up.

The XTR 650w is a rebrand of an OEM Seasonic power supply. For those in the know, Seasonic are a top of the range power supply manufacturers with a very good reputation for making quality products. This PSU is no exception. There is not a lot to say about a PSU, other than it's been running for a year and a half with no issues at all. It has no coil whine and the fan is very quiet. Sometimes I wonder if there is a fan in it at all!I have been very pleased with this PSU and would buy one of these again if I needed to. The price is also pretty good for a gold rated box!

Super Recomendo

Das Netzteil ist solide und hat ein gewisses Eigengewicht.Es läuft bei mir seit Januar 2019 und versorgt mittlerweile einen Ryzen 7 3800X, mit einer AMD Vega 64 (die will gefüttert werden..) und das sehr stabil.Zu dem sind eine CPU Wakü und 6 Gehäuselüfter verbaut.Der Hybrid Mode ist ein nettes Gimmick, das ich aber bisher nur ausprobiert habe.Es ist sehr leise und die Kabelverarbeitung ist perfekt.Dadurch, dass alles nach Wunsch angesteckt werden kann ist man sehr flexibel und hat es aufgeräumt im Gehäuse.KURZUM: Ich würde es wieder kaufen! Keine Ahnung welche Artikel manch andere wohl bekommen haben, aber ich habe direkt bei "Verkauf durch Amazon, Versand durch Amazon" bestellt und alles war perfekt.
