Experience: 1 Years


-Modular (well, semi-modular. The mobo power cables aren't. but it's not like they're optional anyway)
-Very quiet
-Has a good solid & heavy feel to it
-Ball bearing fan is silent & long lasting
-Very clean & stable current, right up there with the best
-5 year warranty
I got this on sale for 115$. Never had any issues.
Seasonic is one of the best PSU manufacturers out there.
Many popular PSU's (Corsair etc) are re-branded Seasonic units.
Current price is a bit steep though... get it if it's on sale.

Experience: 9 Months


-Superb construction.
-Very quiet.
-Excellent reputation.
-Rail output values are incredibly stable, even under heavy load.
-Runs very cool.
-Cables are excellent quality and good lengths.
-A little expensive, try to get it on sale.
What a great unit! I've always loved Seasonic but it's been a long time since I bought one of their PSUs.

I bought this to replace a Corsair CX600M that fried and took half my system with it. I should have been more proactive and bought this first.

Everything about this unit is quality from the casing finish to the flat ribbon style cables. It's fully modular in every way but the 24-pin connector, and I prefer it that way. The connectors are sturdy and clip properly on both ends. The cooling fan is silent and moves a lot of air, this unit can run warm in the summer but never overly hot.

I have run my G750 through my PSU tester and every rail from the 12V+ to the 3.3V+ is rock stable, even under heavy load. This unit has run everything from my overclocked QX9650 and 790i to my overclocked 4670k and Z87-A with no hiccups or failures.

In short if you need a super quality PSU with rock solid outputs and incredible build quality you cannot go wrong with a Seasonic G series.

Experience: 30 Days


more then enough power for what i need, the connection are long enough but not to long where cable management is a pain.
no cons
good pws, hasnt fail me yet.

Experience: 1 Months


Clean Power Output
Cable management (Semi-Modular)
Quiet Fan
Modular cable and connector are well identified
Cable are ribbon ones instead of sleeved
All the required cables to accommodate most setups
AC power cord is 16 AWG instead of 18 AWG
It's a Seasonic lol
HDD cables could be a tad longer
I've had this PSU for a complete month and it does not disappoint. First thing that surprised me out of the box what the thickness of the AC power cord, that's right, there is 16 gauge wire in there instead of 18 one like most PSU ; that will help keeping any voltage drop  at bay under heavy loads. On the first week of ownership, I went ahead and tested exactly how clean the power output with a Snap-On Modis ultra automotive oscilloscope. I got the same results at more or less 3 mv difference from the review these guys did at about 50% load (402 W on the AC input)
I also really like the fact that the cables are ribbon one instead of more bulky sleeved one. In my case, it helped a lot bending them where they needed to go for a clean cable management. I also appreciated that they hard-wired the 24 pin motherboard, 4+4 pin CPU and 6+6 pin PCI-E connector as these are the cables that will be used on 99% of setups. On the other hand, i have a good ol' Raidmax Sagitta Mid size Tower and the HDD cable connecting my 3 drives barely reaches the PSU. I did not need to stretch it nor does the connection have tension, it's just that it is too short to fit behind the HDD and 5.25 in bay all the way up and comes pretty close to my DDR3 Chips.
Overall I would definitely recommend this PSU for anyone looking to power a mid to high end setup with very little ripple. It power my i7 860 running at 3.9 GHZ and my GTX 660 with BIOS Mod running at 1215 MHZ without issue and soon a GTX 970. In fact I could raise the frequency to 1225 on my GPU after replacing my pretty average Thermaltake TR2 RX 750 rev 2 with this one. For those of you wondering : yes I've tried 1225 MHZ with the Thermaltake and it would fail every time after 3 hrs Running Heaven Benchmark. I know it might be pricier than other units but the Capacitors and VRMs on your PC will be thankful. This review was modfied by poster v 11-07-15 02:49 PM

Experience: 2 Days


Modular (not fully)
80plus Gold
Include cable management supplies
Pricy (expected)
8pin CPU cable is a on the short side
I trust Seasonic with no question asked. Super quiet, only non-modular cables are the 20+4pin ATX, 2 x 6+2pin GPU and 4+4pin CPU which isn't a problem since its almost a standard load out for computer nowadays. 4+4pin CPU cable can be a bit longer, everything else is long enough for both top/bottom PSU mount full tower case. It is pricy for 750W but to be expected. It came with enough cable management supply so don't have to buy more.

Experience: 1 Weeks


It is a quiet unit, and that is all I ask for

Experience: 1 Weeks


lots of extra cables
cpu 8 pin is pretty short
like someone said before, the cpu 8 pin is pretty short. it fit fine in my case, but if you have custom/big case, it would be a problem. great product all around, and it comes with a little satchel for the extra cords you don't use.

Experience: 41 Days


quiet, well built psu
It was everything I have come to expect from seasonic power supplies. I have many build using this companies PSU and have never had any complaints. Solid build, even power distribution, low noise and unmatched quality of build !

Experience: 1 Weeks


- Mostly modular (huh, the above pic associated with this product is different)
- Plenty of cable ties
- Motherboard/CPU 8-pin could be a touch longer
This product is quiet and hasn't done anything (which is great, as a power supply really shouldn't make itself known). It is mostly modular, but the cables you will use (such as CPU/MB) cables are permanently attached. Paired with a NZXT H440 it works just fine, though I wouldn't have minded the CPU cables being an inch longer to make hiding the cables a little easier.

Comment: Overall, the Seasonic G-750 did very well in almost all of our performance metrics. Interestingly, where this unit excelled relative to the competition differed somewhat compared to where the G-550 excelled.
