5/ 5
Incredible! Efficient and silent, always.

Pros: - Absolutely silent. At low loads (like my system) the fan never needs to turn on at all.
- Efficient! In-depth review sites show it practically reaches Platinum efficiency, even in high heat environments, all while maintaining rock solid stability.
- Efficient at low load too! 650W is huge overkill for my silent PC, with just a Core i3 and no discrete graphics card, so I worried that I would forfeit efficiency. However, the JonnyGuru review of this PSU shows it maintains an extremely impressive 88.8% efficiency at 9.6% load.
- Pays for itself! I've calculated that at my electric rates this PSU will save me $25/year compared to a "budget" option. For a high-end system powered on 24/7 it would be much more!
- 100% modular, sleeved cabling. Much less cluttered than my last PC, with less obstructed airflow.
- Velvet bag is useful for holding board game pieces for random drawing--I use it for Carcassonne tiles.
- 5 year warranty

Edit: Still going strong 7 years later (Jan 2019)

Cons: - Manual was a little less descriptive than I would have liked for my first PSU install, but easy enough to figure things out.
- Wish they offered it cheaper rather than include a fancy velvet bag and the special bag for cables.

Other Thoughts: Wish I'd bought another one to upgrade my family's PC, where the PSU is obviously the loudest component. Higher power draw too, so the efficiency gains from a Seasonic would really be noticeable on our electric bill.

Not a review. Sorry

Pros: idk

Cons: idk

Other Thoughts: I wrote this so I could ask a simple question that I couldn't find out. Does this come with a Molex cable?

8 years later -

Pros: Juicy 125W on processor rail for an 8 year old 650W beats current 750W's - 100W.
QUITE!! - I will never hear this above the video card or CPU fan- EVER.
Runs like a top. I have never a problem with it.
Modular is nice, works fine for me.
Beautiful boxing.

Cons: None, I have had absolutely no complaints about this PSU.

Other Thoughts: Threw it in an Aero Cool Dead Silence Mirco ATX case in 2010 with a i3-550 for single threaded budget gaming and paired with a MSI 7870 OC GHz edition and this thing has been smooth sailing from day one. This is my daily work machine as well and I've logged 1,000 of hours with this rig and it has purred like a kitten with nary a whimper for 8 years and still going strong. I am looking to upgrade to Ryzen 5 or 7 soon and thought I should check out a new PSU. I looked at the new focused 750W from Seasonic and surprised that my 8 year old X650Gold has a 25W more available on the Processor rail!! This 650W has been stress benched running steady and cool at close or over 800W by a large number of sites back in the day. This is still the mighty mouse 650W of any day!

Ps - Thank New egg. I bought it from you originally and no complaints!

Legendary PSU

Pros: I've had this PSU since 2013 and I am still using it, it has never done me wrong and has survived multiple unprotected surges. It is bullet proof and has gone through multiple different iterations of my system, from I5 2500K to 4690K to R5 2600X. I'm expecting to change out my GTX 770 for a Vega 64 soon and I am still confident that this PSU can manage.

Cons: Perhaps the cables offered in the version I received are a bit dated now.

Cons: nothing from me

One of the best

Pros: Absolutely stable for many years now. Very quiet. Perfect modular design. Plenty of cables.

Cons: Price was substantially higher years ago.

Other Thoughts: Computer has never crashed a single time due to power irregularity.

Very quiet, fully modular

Pros: This PS is very quiet. In fact, you can set to either have its fan on all the time, or only when needed. I chose the latter and so far after a couple of weeks of being always on, my system is fine.

It's fully modular. There are no cables hard-attached to it; they're all pluggable for max control. It comes with plenty of cabling, including lots of SATA power plugs. The PS itself is shipped in a really nice velvet bag and the packaging overall is excellent.

Cons: UPDATE August 2018. After 2.5 years in a lightly used PC, the power supply failed. I sent it to Seasonic for RMA and they confirmed it was dead and sent me a refurbished replacement. The refurb is also defective, sometimes not powering on at all, other times randomly resetting. I am working with their RMA dept. on this but it just confirms my distrust of refurb. Would be nicer if Seasonic instead offered a discount on a brand new replacement instead.
====================

There are no cons for me with this board. Maybe the price, but obviously I knew that and for this work machine with all top-notch components, I wanted the best PS brand.

Other Thoughts: I'm using this with an LGA1151 board and a Core i7-6700 CPU, no discrete graphics card (this is a work machine, and I'm not a gamer anymore).

SeaSonic X650 Gold: Want the best? Look no further...

Pros: Second one I've owned. Never had a problem with either. This one has been the cornerstone of multiple rigs since its 12/31/18 purchase. The SeaSonic is the gold standard among power supplies.

Cons: None. Never skimp on power supplies people. Except nothing but the best. Go with SeaSonic or Super Flower-manufactured (i.e., EVGA) power supplies.

Other Thoughts: Most of the negative reviews are from miners trying to cut corners by putting too many GPUs on one PSU or clueless dodos who have no business building a computer in the first place.
