Super Flower SF-650F14HG(BK) Leadex III Gold 650W 80 Plus Gold Fully Modular Black Desktop Power Supply

This is an exceptional power supply for most low- and mid-range PCs, you can't go wrong with Super Flower - some of the best quality PSUs I've used.
This one in particular, I am using on a low end system - and since the PSU is actually 90% efficient at 50% power, this is doing really well in there.
And since it's modular, you can optimize cable management and only use what you need.
The stability provided by a quality PSU is the most underrated part of system building IMO - don't skimp on the PSU.

this is a great buy. i only wish i had waited a few days to get the 750w version because they are basically the same price. it was out of stock when i bought this one.

This was my first modular PSU ever and I must say I did't know what I was missing. My current case is rather small and after having the modularity factor it helped immensely with cable management and overall looks.

I did a lot of research on various PSU brands and options. I had wanted to keep my budget closer to the 1k mark but after doing plenty of research this was a no brainer. Its in the highest rated tier on the official/unnoficial list of PSU ratings you can find out in the wild.

I bought this to power a new XFX Radeon 7600 I purchased and its been working like a dream so far. Great purchase and great price!

I only got an entry level am5 pc to this is more than enough. very quiet. All the labels are correct. you dont have to change any settings to make it work. I wish the VGA cable were pre attached to make inserting into the psu alot easier

Incredible efficiency. This power supply is so efficient when not under load just as advertised. Lovely packaging, nice to have a bag provided for the cables as well. my build only needs the 24pin motherboard, 8pin cpu and 8pin gpu connectors hence why I opted for this fully modular unit. No regrets, I was a bit skeptical by Superflower but after discovering that they manufacture power supplies for all the popular brands I was a ease. Honestly, the best bult quality and I highly recommend this product.

It runs silent, you can choose three settings when it comes to the fan, but the case I have it in doesn't run hot at all, so the first setting is fine and I don't even hear it.

Cables are clearly marked and comes with nice cable shrouds to keep everything neat.

A good replacement for my old unit.

The modular design makes cable management a breeze and it is dead quiet. No more singing fans.

My GTX1070's fans were blasting lately and had no idea why. I decided to get a new PSU a lay my 7+ years old Voltron to rest. My GPU runs silent now and the fans do not ramp up like crazy? Why?...Who knows and I don't really care but I think she was on her way out. Cable management was a dream and I am now ready for my new GPU, when stock comes in ;(. The delivery took a day longer than expected but well worth it, thanks Woot!

Powers my RTX 3070, Ryzen 7 5800x, 32gb RAM and SSD + HDD setup without issue. I would recommend buying this, especially since it's Gold rated. Not much more to say but Wootware has a word limit so, yeah, it's good. Would recommend. Enjoy your build!

The title described my conundrum as I struggled with the decision.

Both at the Same price as of writing.
The simple truth of the matter is:
If I buy anything more powerful than an RTX 2080 Ti GPU, I will require a 750Watt PSU..
And a GeForce RTX 2080 SUPER will run smooth on a 650W PSU.
More so on a 80 Plus Gold Rated Super Flower PSU..

Brutally easy to install, comes with loads of cables and some spare as well.
A nice cable bag and a very pleasing unboxing experience.
It looked very Professional when I opened it ,and one can see some thought went into it by someone who cares.

I read this review on the PSU and am very glad I bought it:

So this is my first fully modular PSU and I couldn't be happier it has made cable management so much easier and and less cluttered, also very big plus for optional fan speeds. Also plug and play no need to change any switches and before plugging in.

This is the perfect power supply for most single-GPU builds. I was looking to upgrade to a modular PSU to sort out my cable management and couldn't be happier with this. I'm also aiming to upgrade my RX 580 to an RTX card this year and it's reassuring to know I've got the right PSU. 80+ Gold is the cherry on top.
