 I have another XFX power supply to unbox. So this one is slightly different from the last XFX power supply that I took a look at. And in terms of the overall platform and the overall feature set, it is fairly similar. However, this is a higher wattage unit than the 80 plus platinum 1000 watt that we looked at before. So this is a 1250 watt power supply, which yes there are higher wattage power supplies out there, but I would say that for all practical intents and purposes, 1200 watts or 1250 watts or whatever you want to call it is pretty much as high-end as you need to go because you can power almost anything I can imagine. I mean okay yeah you can add pelchies and things like that to your system that would make it consume more power, but with this you can easily power four graphics cards or quad core or rather quad cores aren't even high-end anymore, I forgot. A six core CPU and you know all the extra little random peripherals and accessories that you could want. So the one that we had a look at before was the 1000 watt one and that was more of a limited edition skew and I just hold on a second hold on just a moment. So the 1000 watt is the limited edition 80 plus platinum and then the 1050 and the 1250 watt are the black edition non-limited edition one. So these are 80 plus gold which is to be expected because 80 plus gold is a little bit easier to achieve especially with a 1250 watt unit. I mean look at what you'd be expecting from a 1250 watt 80 plus platinum unit we're talking what 90% efficiency basically for 1250 watts. So what does it have in terms of the overall other features that are similar to the 80 plus platinum unit? The answer is a whole lot. It actually looks very similar so XFX has done a great job. I mean back when they first launched their power supply as I was looking at it going well what can XFX do any different? And what they're doing is they're using a very high quality manufacturer for the power supply units themselves and what they've also done is they found a way to set apart their aesthetic from what others are doing. So you look at it and you go well really anything but black tends not to look that great like you go and you do like you know like a bronzy colored power supply and it might look kind of cool on its own but you go and put that in the system it looks kind of out of place. I was like okay well what are they gonna do? And what they did do is they did kind of a unique overall look so it's got a very XFX-y look to it. It's still black. They've done kind of silver accents and rather than going the rather than going the you know cover it with gold colored stuff route that a lot of guys have done with their 80 plus gold power supplies and when you combine good aesthetics with very high quality I'd say you generally speaking end up with a winner. So that's that's what they've decided to do with their power supply products and I have no hesitations whatsoever in recommending their power supply products. So they do okay I'm gonna say it one more time they do use a high quality manufacturer and then they do offer a five-year guarantee that's from XFX so that's their legendary warranty service so it's hard to go wrong that way as well. Let's have a look at the modular fan interface where you're gonna find a few different things. So you'll see your motherboard modular connector so it's a fully modular power supply you also see a CPU connector so that uses an 8 pin to 8 pin which I'm gonna find right about here. Alright so that guy plugs in right there and then what you see is three more PCIe connectors and then an additional PCIe or CPU connector so that means you can either use this guy right here to do another 8 pin although I would personally argue that unless you're using a dual socket motherboard that is entirely unnecessary. So a single 8 pin even if you're okay I don't by dual socket I mean dual CPU sockets not dual 8 pin sockets so I would argue if you have a single CPU you're going to be more than enough served by a single 8 pin connector even if your motherboard has two connector slots so what that means is you could use this power supply to provide up to 8 PCIe connectors so that is up to four way dual pin requiring graphics card so you can see each of these connectors nice long cables has dual 6 plus 2 pin connectors at the end and XFX includes four of them so with the 1050 watt they include three and with the 1250 watt they include four and then they also include the CPU one so you can actually use it whichever way you want because if you're running two or three graphics cards and you do have the dual 8 pin connectors on your motherboard then I guess you might as well use them both high quality power cord included very very thick good to see it's just those little touches that do make a difference oh I want to talk about you know what I'll talk about that after okay let's have a look at the rest of the included connector so you got your 24 pin which is pretty much bog standard I would hope that any PC power supply comes with a 24 pin connector do I have all of them here yeah okay so we've got a three by SATA connector one so two of them are right angle one of them is straight then we've got a two by SATA connector one right angle one straight that's what I'd recommend running up to your optical drive then we have another three by SATA power connector and finally another three by SATA power connector so that's nine that you can run over to your hard drive bays and then two that you can run up to your optical drives which is a good balance okay next we've got a dual molex I'm a big fan of this because I don't use many molexes in my case so I'd run that to my pump and I'd run that to my fan controller and then I'd be pretty much done then we've got one of those molex to dual floppy adapters just in case you still use any floppy devices in your system whether it's a card reader or whatever else they need floppy power they need it you got a triple molex and then you've got another triple molex that is also included now this is cool check this out I wonder if we can see the solid link interface down there you know what we can't see that but we can see something so I want you guys to check this out you know how on most modular power supplies you see a big bundle of cables coming off can you see inside sort of kind of try and get an angle where you can see along the right hand edge so most modular power supplies you'll see a whole bunch of cables that are soldered down there and then run over to the back of the PCB that makes up the modular interface which is going to be right behind here the way that these power supplies work in order to conserve efficiencies rather than using those cables and those solder points which tend to be somewhat inefficient they use solid pieces actually here they have a good diagram here where is it they use solid metal pieces to run right off the PCB onto the modular interface itself so you can see what it looks like with this with this back piece taken off so that does provide I mean we're talking very small amounts of increased efficiency but you'd be amazed how much how much these things can add up over time like I'm aware of at least one 80 plus gold power supply where this was a less reputable manufacturer this was not fx FX so don't don't take that away from this story but what they did was when they actually sent their unit away to the 80 plus certification committee they included cables that were 30% shorter because just that extra little bit of resistance that they're taking away from the power output earned them an 80 plus gold certification instead of 80 plus silver so that's something to bear in mind if you're buying a power supply you want to buy from someone reputable who doesn't sort of fudge the numbers in order to hit a particular plateau that's actually one of the other things that X FX really feels is important so their capacitors and their operating specs are based on a standard operating condition of 50 degrees so they're not actually going to go ahead and put the power supply in a colder environment which does help it perform more efficiently in order to achieve a better rating they're putting it in a more realistic scenario so they've got all Japanese capacitors as well as testing them Wow cool so they test them at 50 degrees and they're rated to withstand up to a hundred and five degrees automatic protection sensor so you got all of your usual safety certifications I would expect that from someone like XFX as well as from the manufacturer that is building the power supply in the first place because I mean when it comes to actual manufacturing plants someone like an XFX is going to stand behind the warranty for you they're going to support the product for you they're going to bring it to market for you they're going to do you know promotions and MIRs and all that good stuff for you but when it comes to an actual factory not everyone owns a power supply factory so they are using a very very high quality OEM arguably the best one out there hybrid fan mode so we're finally on to what I think is really the best feature of this particular series of power supplies their black edition full modular and that is hybrid fan mode here so when you enable that feature what you're actually doing and they include a useful graph right on the power supply itself I will show you that graph when I find it aha very cool check this out so up to 20% load plus or minus 5% you it operates in silent mode that means your fan is off remember 20% load on a 1250 watt power supply is about 300 watts you'd be hard-pressed to find a system that idols above 300 watts in fact let's take this system right here which is dual GTX 580s and a 2600 K no what is this this is a 39 39 30 K 6 core processor and I'm gonna go ahead and I'm gonna show you guys this system idols at 144 watts check that out can you see that it's okay you'll have to take my word for it it idols at 144 watts 8 gigs of ram the works so that means that whenever you're browsing the web or doing just general low-maintenance stuff your power supply fans gonna be off that's great not only for noise reduction but also for dust reduction that means your power supply isn't even gonna get dust caked into it because unless you're actually playing a game rendering a video or doing something intensive like that your fan isn't even going to be on so this is by design if you flick the switch you know don't be scared that your fan isn't on but yeah pretty cool right okay two more things one is that this is a single rail power supply so it's a capable of providing up to 104 amps on a single rail that is only 2 watts shy of the entire rated output of this power supply so what that does mean is that you don't have to worry about which connector you're plugging what high draw device into so you know short of accidentally plugging everything in your system into a single molex connector and overheating this entire wire which is very unlikely to happen you don't have to worry about having you know two graphics cards on one rail and one graphics card on the other rail and accidentally triggering the overcurrent protection don't have to worry about that you just go ahead and worry free you plug everything into everything and it's all coming from a single 12 volt rail inside the power supply so thank you for checking out my unboxing of the XFX Pro 1250 watt solid link 80 plus gold power supply and don't forget to subscribe to Linus Tech Tips for more unboxing reviews and other computer videos and honestly if you're shopping for a power supply tomorrow look for one with hybrid fan mode so remember the XFX 1050 watt 80 plus gold the 1250 watt 80 plus gold as well as the 1000 watt 80 plus platinum all have this feature and it's very very cool
