Cons: Cables are a bit stiff, but might be a + (high quality)

Pros: Gold quality power j low cost, japan capacitors, mostly silent (read below). Lots of cables for all your needs
Comment:
I was in the search of an efficient PSU to power my rig (i5 4690K + R9 290). I don't need crossfire support, but I wanted something solid and easy to work with. The last system I built dates from early 2000's, PSU were way cheaper back then, low watts and I burned a couple in my early gaming years.I wanted something fully modular, so less cable clutter in the case. Also, the gold rating is nice and this has hybrid mode power ( user selectable). The fan remains off when power demand is low (browsing the web, etc...).As soon as I fired my first game, it came to life, but it is really silent, you have to be near to hear a faint whirring sound.This is supposed to be rebranded SeaSonic PSU's, synonym with high quality, so you can't go wrong.I suggest getting a bit more power than needed (I would have been OK with 600W, but decided to get a 750W so the system stays in hybrid/silent mode a lot longer= less noise). Check the specials and pull the trigger when on sale.

Cons: The Molex connectors are freaking stiff

Pros: - XFX Brand- 80+ Gold Cert- Enough Juice to run your hardware- Fully Modular
Comment:
I bough this PSU got suggested from a tech here on the forum, and cant complain at all, the only draw back the molex connectors and cables are freaking stiff grrr.. Otherwise full modular, the on / auto switch for the PSU fan I just lived on .Reccomended

Cons: Mail-in rebate is blatant scam

Pros: Works as described. Decent product for the price.
Comment:
This product is very solid for the price. I have no complaints. If you are buying this because of the rebate you think you're going to receive, I would reconsider. My rebate was denied because they said I did not sign the form. They provided a link to a scanned PDF showing what I submitted. The one and only correct rebate form is, in fact, signed. They are clearly making stuff up in order not to pay their rebates. Just a friendly warning to future purchasers.Product = Good. Manufacturer = Questionable.

Cons: none so far

Pros: fully modular
Comment:
My Antec 850 died and I used this one to replace it. I have always had issues with this system. Memory issues, sound card issues, blue screen issues... I had, under warranty, replaced most of the components in my system. Was able to get the system mostly stable. After replacing the Antec with this Power supply, all of my problems have disappeared. I MEAN ALL!!! And the fan setting on the PSU makes this one virtually quiet. I am able to overclock and push this system like it was meant to be!VERY SOLID PSU, highly recommend it!!!

Cons: Cables are very stiffNot Black Edition, Actually XTR

Pros: No Coil Whine (YMMV)Low Profile CablesGreat ValueHybrid Fan ModeFully Modular80+ Gold
Comment:
Picked this up for a high mid-end gaming build and has been working flawlessly so far. There have been concerns of coil whine in these Seasonic-based XFX PSUs, but I have not noticed any noises whatsoever. The value and features that you get from this PSU at this price point makes it a solid choice for any build that needs no more than 750W. My only gripe is that the modular cables are very stiff, which detracted from the overall experience. Other than that, you definitely get a fair bit more than what you pay for, and with a 5 year warranty to boot, I would highly recommend this PSU.

Cons: it works fine and quiet.

Pros: power supply from seasonic and good quality
Comment:
The new stock is not black edition. it is a XRS750. I think it is not based on seasonic km3 platform but on seasonic G. Seems good but it is not the old design.

Cons: VERY slight buzz. Can't hear it unless I put my head 10cm away from the PSU.

Pros: SilentFan doesn't spin at low loadsRebranded SeasonicTons of cables includedLooks slick (both the power supply AND the cables look nice)
Comment:
Very satisfied with my purchase. I sent my MIR at the very last minute (the day before it was about to expire) and it was approved with no problems. The slight buzz doesn't really annoy me and I can't hear it unless I put my head extremely close to the PSU. I remember that XFX responded to coil whine/buzzing complaints on an NCIX competitor's website that the issue is covered under warranty, so I'm not too worried about getting the problem fixed if I ever feel like it needs to be addressed. Overall, you can't go wrong. Very good price for what you get.

Cons: mail in rebate scam.

Pros: Works as advertised, I have no issues at all with this power supply.
Comment:
The rebate I mailed in was rejected as they claim I never included the barcode from the box, that was bullshit as I triple checked everything. Never trust mail in rebates, is a freaking scam for this. PSU is good though and good value (just don't count on mail in rebate).

Cons: Transformer Coil Whine when PC is asleepIncluded cables are chintzy

Pros: Works as advertisedNice packaging
Comment:
Generates a whine when the PC is in sleep mode. Very noticable - makes it impossible for me to sleep in the same room as the PC is sleeping in. Seemingly the only way to eliminate this is to unplug the PSU each night :(

This has been the best psu i have ever gotten, i am happy with this purchase. Didn't get it on sale or anything like that. For a gold+, 750watt, and being fully modular it has been the most cost efficient piece of hardware i have ever gotten.

Comment:
I upgraded from a corsair HX620watt. After installing the xfx I actually noticed a difference in my computer. It felt as if now it was getting all the power that it needed to run properly. My spec: i7 3gen 3.5ghz ( not over clocked )Asus Maximus mobo16gig corsair vengeance memory 2x ATI HD 7950 in Crossfire3 Hard drives1 SSD driveDVD-Rcorsair h80 water cooler - has 2 120mm fans on it. 3x 120mm Fans Blue lights.There is more then enough power to run my system. The only reason I can think of for me to have gotten a 800 or 850watt psu is only if it were on sale and in the same price bracket. I did get this psu for 100 which is a very good price for a psu that will run 2 high end graphics card with ease.Very Very Happy :)

Cons: 1. Moderate coil whine.Varying degrees have been brought up in reviews elsewhere for Seasonic KM3 units. Mines doesn't seem like an isolated issue.2. Ribbon cables.Only the ATX cable is sleeved (to prevent cuts from the case)3. MIR4. The modular connectors may be very tight to clip and unclip the first time

Pros: 1. High quality parts and specs2. Fully modular3. Borderline 80 Plus Platinum efficiency for a Gold Unit4. Hybrid Mode fan won't spin at low loads5. On sale around $100 after MIR
Comment:
Overall an excellent unit, except for moderate coil whine, which review sites rarely mention for PSUs. It could be heard up to 2m away, more or less if I turn my head with the left ear facing it, or through the computer case if has fan vents or not. Only unplugging or the off switch makes it go away... for now. 4 stars for that.

A great power supply with plenty of power.The cables are sleeved beautifully, wiring is all black all the way to the connectors, which was important to me.It also has something known as "hybrid mode" which will turn the fan on and off as the load changes, but I haven't found the need for it, it is very quiet.All in all, it looks/sounds/performs great, and it's fully modular - you can't lose.

Great PSU and so far nothing of issue has come up. Seems very solid and Priced well. Not much else to say about a power supply. The extra's included in the packaging are great and it came very well protected. For a power supply it does the job perfectly.

It's just a very solid power supply which does as promised. In many of the reviews I've seen people have pushed over 900W on the 12v rail on these bad boys. Not bad.

Cons: NOT advertized correctly by NCIX as 70Amps - It is 62 Amps and tops out at 951.4 Watts with an astounding 84.3 Efficiency. The XFX Pro 850w Black Edition is 70Amps.

Pros: I bought the XFX Pro 850W Black Edition P1850BBEFX but had to say something about this XFX product.Fantastic PSU by XFX for the Price in comparison to the Seasonic X750 or Corsair AX760.It is a Seasonic KM3 Clone with all the High Quality Transistors and Capacitors.Passes Platinum Specifications with a 91/92/89 Efficiency
Comment:
Generally priced on Sale at around $119.49.I happened to Purchase the XFX Pro 850w Black Edition P1850BBEFX here at NCIX for $119.49.Keep up the Great Work NCIX ;o)

Comment:
I got this for a smaller budget build and it's working perfectly so far, with enough wattage for a small room of oc'ing. Got this one sale for only 10 dollars more than the regular edition. Overall, a great little power supply on sale, when not, would recommend the normal edition.
