Well Newegg has photos of the XT series now. Still nothing on their website about it though. I wonder if they rebranded the Pro series with a more basic looking case, same internals, and adjusted the wattage ratings a bit? Curious indeed.

Scratch that, I missed the post above about them not being rebrands... I really hope they are of quality though 🙁
 
They don't quite look like Seasonic to me from what is visible on the photos, but my usual information sources don't say anything conclusive yet.

A foreign reviewer has got the three models and said that they do come from Seasonic, so he is to trust for now until there's any new info.
 


Sounds good. Interested to see results of testing and someone, not me!, to crack one open.

As I understand from this thread, SeaSonic is XFX's only OEM manufacturer.. as of now. I took a chance and ordered a XT 500w, so I hope it's nice.
 
Those are actually VERY interesting if the quality is as good as we've come to expect on Seasonic built units. Those prices make them very competitive for a Seasonic built unit. Internal selection of components might be the determining factor on these though, not just actual build quality which we know is almost always good from XFX/Seasonic units.
 
Regarding XFX XT:

Newegg photos, high res scraped and lightened up:


Quadruple heatsink design - bridge rectifier, PFC, switchers and secondary transistors.
Black and gold capacitor visible on the right - looks kinda like the golden Capxon GF, but not quite.


Black heatsinks on 500W and 600W versions - Seasonic does that sometimes.


PCB screened for additional unused X cap in the top right corner - omitted and bypassed via a jumper wire (cost cutting). Black and gold X-vent cap on the bottom (not Teapo, as you could expect from their "Taiwanese capacitors" claim) which again could be something like golden Capxon GF or OST.


(500W) Different heatsink shape - similar to what Seasonic uses sometimes. Plain ERL-35 transformer marking - never used by Seasonic.


(600W) More transformer markings, not used by Seasonic so far. The half-visible X-vent capacitor in the bottom seems to be brownish-reddish in colour - could be Su'scon.
 
XFX has the naming all screwed up. If you look on the Amazon page here for this unit:
81GSPS6mavL._SL1500_.jpg


This unit seems to have 3 names:
XFX Core Edition 850W
XFX XT 850W
XFX Pro 850W


It says Pro on the side, but the technical name as given by the Jonny review is XFX Core Edition. Product page says XT. Gee whiz, get your communication together @companies.
 


Reminds me of a teenager with an identity problem/
 
The XFX Core Edition 550W is commonly recommended on this site, probably the most recommended PSU, but nobody ever knows what to call it because pcpartpicker doesn't even give it a name, well it has P1 in the model, but everyone just calls it the XFX 550W.

It's the XFX Pro series.
 


So what did you buy it and dissemble it? If they're getting rid of Seasonic, it better be someone good, or else XFX will fall into the pits of low quality PSU darkness.

Where do you publish your articles?

So, remember a while back I was talking about some changes I'd like to see in the tier list, and you guys told me to just make my own? Well, what do you know, I had already been working on my own tier list I am developing. So far there are 210 power supplies in tiers. I have worked countless hours, probably hundreds, daily on this so far. The purpose of the list is not to do away with this list, but rather to act as a supplement to it, or a standalone, separate list. Here are some changes and details:

-There are 6 tiers instead of 5. Tier 6 (the worst tier) units are no longer a list of brands, but rather are power supply models like the other tiers.

-I am more strict when it comes to tiering. I am hard on the PSUs. If a power supply has fantastic voltage regulation, quality capacitors, but has out-of-spec ripple on the 12V rail, the good things will not balance out the bad, but rather it is placed in a tier in accordance with that bad trait. This way you can assure yourself that if you are buying a Tier 2 power supply, everything is Tier 2 worthy about it, rather than just some aspects.

-After Tier 6 is Tier UN. "UN" stands for "unknown" which will be a long list of power supplies with unknown quality. The 210 PSUs I already have tiered do not include Tier UN. You could almost consider it to be an untiered unit, but without the indication that it will be tiered, because many never will be. It'll be recommended not to buy these units.

-Discontinued units will be included in the list, of course dating back to a reasonable time, in which the 12V rail plays the prominent role. No 1990s PSUs.

-No more grouping of a series together. Only specific models are placed into tiers, and only specific models are judged. Reviewed models are not judged as a whole series together, and are not judged in accordance with other models in the series. Basically, no series grouping.

-No more color-coding of the efficiency. I don't care for efficiency, and I don't want people getting the idea efficiency determines quality, so models are all the same color. If a unit fails to meet its efficiency, though, in a review, I will definitely take that seriously as it is something false about the unit, but that is a rare occurrence.

-If a power supplies have disputable or similar names, the model text is included in parenthesis to be specific about the exact units.

-If a power supply has no normal name then simply a model text is used as reference to it (OEM units for instance).

-If a power supply has relatives (similar-wattage models in the series) that have been professionally reviewed, but it has not been professionally reviewed, it may be placed in a Tier according to what it is suspected to be and will be color-coded blue to indicate a professional review has not been done on it but its quality is predictable enough. They are different from Tier UN units, because the blue units are predictable, but the UN are unpredictable and have no similar relatives with reviews.

This is a clean-slate tier list. I do not place anything in tiers based on what tier it is currently in on this list, nor do I place it in a tier based on the conclusion statement at the end of a professional review. I analyze the data myself and place it into a tier I believe it is justified to make a living in. Hopefully in a couple of weeks it'll be released.
