Pros: I burned this psu in on a old P4 system by running it nonstop for a week to stress it. Rails are dead on, no high pitched noises or voltage hum. It's the V2 version. Ability to allow the fan to run slowly for more airflow even though it's not really needed until after 50% draw. The Sanyo fan will easily outlast the PSU even running 24/7.

Cons: None, I even received my MIR for 20 bucks, it's always a bonus when those show up. A PSU of this power and quality for $90 is a steal!!

Overall Review: As other people have mentioned this psu is designed to be mounted on bottom cases due to the orientation of the sata plugs. They run bottom to top, not top to bottom. You can mount it on top but the lines would go towards to bottom of the case, bend and go back up to be correct. A tall tower case the line most likely won't make it length wise.

Pros: Has not died in a month.

Cons: 24pin Mains, 8PIN CPU, MOBO power cables are too short My corsair 600T has the PS at the bottom and my Asus Rampage IV extreme has all the connectors near the top of the board. I had to bend the 24pin main in such a way that I actually broke off one of the wires from the 24pin plug and had to solder it back myself.

Overall Review: I am having other issues that I have not tracked down yet. I pray it is not the Seasonic Power supply I have high hopes for this unit but the cabling issue was upsetting. Will report back in another 6 months

Pros: Here is the deal. You really get what you pay for in this SeaSonic Platinum 860W PSU. I like the extra frills, the velvet bag, the cable ties, etc. Just what I would expect with any top of the line produce. The modular design makes the inside of my case look sweet and uncluttered. No coil whine and quiet running. This has plenty of power for my needs and if I want to add another 680 I have the power to do it. If you want a Platinum rated top of the line PSU, this is the one for you.

Cons: None.

Overall Review: Buy it! You'll like it!

Pros: *it's a Seasonic (maker of many high-end OEM brands) *fully modular *true 1000W continuous power supply (no peak value) *Exceptional voltage tolerances! *comes with everything you need (e.g. velcro straps and small screw driver) and 2-pocket handy bag to store unused wires and accessories

Cons: none, I just fell in love :) There is only 1 remark about model numbers, it seems that Seasonic sells them under 2 model numbers while they are one and same unit, look for either PLATINUM-1000 or SS-1000XP, it's the same thing.

Overall Review: Tested this PSU on multimeter using thin backprobing leads and was shocked how accurate the voltage reads were: +5V read 5.02V +3.3V read 3.34V +12V read 12.04V -12V read 12.80V I would HIGHLY recommend this PSU to anybody looking for reliable performance at top notch for years to come, overclockers get this while it lasts! JohnnyGURU review gave this PSU one of the highest marks in history, well right and dead on the spot as per readings. The best PSU I ever had to day.

Pros: Very nice packaging. Hybrid mode: Fan stays off until heavy power draw

Cons: Does not boot the system with a GTX780 video card! Boots perfectly fine with an old 9600GT. I'm a professional engineer and have built over 70 systems so I am sure I have everything connected properly and that the video card works perfectly in this system with other power supplies.

Pros: -Very tight voltage regulation (mine is within 1% at idle and load) -7 year warranty -Insane efficiency (88%-90% tested from 120W to 660W) -Modular -Well known brand name -VERY high build quality! No cheap capacitors, has large aluminum heatsinks, and no sign of sloppy soldering. -Tons of cables included -Smaller version of the very well-received 1000W version -Fan is silent at idle and barely noticeable on a 660W load -Fan appears to be a San Ace model which are on the higher end -Sleeved cables (semi-transparent black so color bleeds through) -Comes with a 'powered by SeaSonic' case sticker

Cons: -Comes wrapped in a velvet bag -I hate their style of 4 pin peripheral molex connectors, not 'loose' enough

Overall Review: ALWAYS check a professional PSU review before buying one! User reviews rarely test voltage regulation, stability, build quality, efficiency, and wattage limits! This is powering an i5 2500k @ 4.4 and two crossfired 6950s in a custom WC loop. The voltage is so stable compared to my previous Thermaltake which was making hissing noises under load and dropping the 12v line to 11.45v under load. This PSU is ALWAYS staying within 1% of the target voltage! The PSU is one of the most important and fail-prone parts in a computer. If you are serious about computing, then you need stable, constant voltage from a PSU that won't catch fire or blow a cheap capacitor down the road. Note that this PSU is just a tad longer than a standard ATX one, though I imagine anyone in this price range has a case that will accommodate it. I needed to use some extenders in my 800d in order to have decent cable management. The cables were a few inches shorter than the ones in my previous Thermaltake

Pros: Excellent warranty service through manufacturer. I had the previously reviewed power supply that failed within 30 minutes. Seasonic was exceptionally quick about sending a new power supply to me. Two days running, the replacement power supply is working fine. Every manufacturer puts out a defective part from time to time. How they handle RMAs really shows what a company is made of. Seasonic was exceptionally quick and professional in my case.

Cons: See previous review

Pros: Please ignore the comment/review below mine - the poster can't even put half a sentence together or even really state what the problem was (it could have been the power supply, but he never specifies the issue at hand). I've only had this PSU for one day, but it is working like a charm. Even if I experience something like coil whine or total failure, I will still give this PSU another chance provided my RMA goes smoothly. As you can see, two of the reviews here which gave this PSU a one-star rating are for completely bizarre reasons unrelated to the actual QUALITY and PERFORMANCE of this power supply. I've read countless reviews and conducted my own research for days - when I saw this PSU on sale, I grabbed it without thinking twice. This is THE best 1000w PSU in the world right now. Independent testing has shown this to be THE MOST STABLE as well, and a TRUE Platinum.

Cons: Relatively expensive, but it's worth the price even without the promotion/discount. However, for someone on a budget, there are cheaper options which are nearly as good (Corsair/Seasonic 80+ GOLD options primarily). Some people have complained that the cables are a bit short, but I think they are OK. I suppose if you have a HUGE case, then it might be problematic.

Overall Review: Like I said, I'm never one to buy into another simply because of hype. However, I am very satisfied with this product thus far, both for its quality and performance. If I ever have any issues, I will come to this reviews section once again. However, with Newegg RMA to back me up as well as Seasonic's 7-year warranty, I don't see any problems in the forseeable future. A good system should always start with a proper spine - solid case with good airflow and cooling potential, a proper CPU cooling solution, a reliable motherboard, and an efficient, powerful PSU. If you want the ability to upgrade your system with multiple SLI/Xfire configurations in the future, DON'T GO CHEAP ON YOUR PSU!!!
