Awwwwwe, It's cute!
4 Stars
Awwwwwe, It's cute!
Reviews are blended here, so this is for the SFX-L 650W version; As stated right above this ^.Probably the best ALL AROUND SFX-L PSU out there. Top performance, average efficiency, then fairly quiet. Even though dimensions are given, it's still pretty cool to see a 650W PSU this small in reality. It has a 120mm Fluid Dynamic Bearing fan which takes up the entire bottom/top, so just look at any 120mm fan and that's pretty much how big it is. If anyone is facing space issues, I'd highly recommend this unit even if your SFF case allows for a full ATX sized one.I end up using only Seasonic PSU's for their exceptional quality and attention to detail and this is no exception. I use to think their included storage bag was overkill but you know what? Now I expect stuff like that just in case I want to take my PSU out on the town. From the Nichicon hold-up cap, through all the Champion controllers, Rubycon, Chemi-Con, and what looks like FPcap filters, and dual 2x Infineon main switches, not one corner was skimped here.Reading reviews prior to purchases, I have heard earlier units only had one EPS connector, but mine positively had a dual-headed EPS connector. With SFX usually being used in iTX builds that don't need it I don't see the concern, but it's there now if you want to use this on something that does need two EPS connectors.I have mine in the pictured Fractal Node 202 and cabling is a cinch. The picture is without the 1050Ti installed for other reviews, but you can see how simple it is by just stuffing it in there. For those that care more, you can separate the ribbon cables, bundle them up into a round bunch and be much more clean...I love ribbon cables for just that ability! Here, I just don't think it matters much with a 65W TDP CPU and separate chambers for the already cool-ish GPU. It's a Blu-Ray player sized case, sorry for no banana for scale.There's a 450W version a little lower priced but I would pick this 650W version and here's my reasoning. This is a reasonably quiet PSU for it's size up to about 300-350W usage which is perfect for mostly everyone. However, after that the fan ramping/profile is very aggressive which I feel is actually loud. I imagine, but can not confirm, that the smaller model would have a profile just as aggressive and would ramp up to "loud" under even lower loads. Take that with a grain of salt because no normal load really gets above 250W in the normal world and this was found only while benchmarking the PSU and the PC itself where these are extreme pulls. The Corsair, which may appear better on paper is just flat out LOUD throughout the entire fan profile and would not recommend for SFF which end up in the entertainment center.It's also just above the 88% needed to gain the ETA-A "Gold" but I really feel most of that is just a sales pitch since Platinum is 90% so does that 2% have an RoE? Wanted to mention it because at times I had anomalies that put it riiiiiight at 88.08% that I can't explain. Others got more solid/repeatable results so I call myself out here as being flawed somewhere.I would buy this again for sure and highly recommend the SFX-L 650W version to anyone looking for a small power supply for a SFF build of any usage. The case had an option for their own PSU which was much lower cost over all, but all problems seem to start at a bad PSU...so piece of mind is worth more to me than dollars.

5.0 out of 5 stars Long Warranty, Amazing/Quality Product, and Platinum Certification!
Reviewed in the United States on September 16, 2019
The Seasonic Power supplies are very nice, It features a 10 year warranty, Fully modular Cables, and a platinum certification. This power supply is of great quality I am very impressed. As this is my first time purchasing a Seasonic product, I am proud to say I am extremely Satisfied with the products that Seasonic Manufactures.

Installation:
The installation for this power supply will vary upon case, But with the Cooler Master HAF XB Evo, it was fairly simple and cables were very lengthy, and of nice quality. All of the Cables plugged in with ease, and fit snug in the power supply. Length of cables is plenty for cases of all sizes, and allows for good cable management. Everything you need will be included in the box, such as some handy zip ties, and Velcro ones as well.

Performance:
Now while this power supply is already quiet, the Hybrid mode will make it change when needed meaning that fan will only spin when it needs too. It's a nice feature to have. On top of all that It is a very nice power supply that is very efficient, and will provide enough power, for a high end system, and future proofing.

Overall: If this is on sale on a good price, I would totally recommend that anyone purchase this as it is a very nice power supply and should be enough for most people. Quality is there, as well, With a 10 year warranty, and a good company behind it, there should be minimal to no problems with anything that may happen. This having platinum efficiency is also another very nice thing to have, as well with the modular cables for cable management for all kinds of cases.

With the market always changing check your options on power supplies, including sales on power supplies, and prices changing by the days. Always check your options. But this power supply, and brand is very recommended by me, glad I gave them a chance!
