using it a couple of days to power at 4650G and 3060, so totally overkill in terms of wattage
you should swap it with a Noctua fan.
Looking into a Noctua fan swap, for sure.I'd say that is a good match. When it comes to FLEX PSUs I definitely prefer to use one with "overkill wattage" and then replace the noisy stock fan with a Noctua to get a more quiet setup while not having to worry about the PSU dying from overheating
Great review, and one that made me feel alright enough to purchase it.
Been using it a couple of days to power at 4650G and 3060, so totally overkill in terms of wattage.
if you're looking for a 6.0 litre case, with NFC SkySlots, to go with it, this video has what you need :
and here's a photo of the finished version (buyer chooses screw type) :
I am looking for a PSU upgrade and Flex options are quite limited. Based on the build quality I am somewhat concerned. Of course anyone can put labels on, and until there is a full PSU test and review.
I have the Z-case P50 case along with a Enhance 7660B PSU from SFFTEC powering a underpowered 5800x at 65W and a RTX 3090 (at 90% power) on a custom liquid cooled loop with 8 fans.
Obviously not ideal, but is stable to run triple AAA titles at 4K at decent FPS. I am looking for a PSU upgrade and Flex options are quite limited. Based on the build quality I am somewhat concerned. Of course anyone can put labels on, and until there is a full PSU test and review, I am hesitant to try this PSU out on my build. It is an intriguing option.
Josh | NFC tested a modular FSP unit, in the above video.
Josh | NFC believes that the 7660B is noisy at 500W, while the FSP FlexGuru w/ noctua fan, is semi-silent at 500W.
but his test might be faulty.
Excellent work!. Very informative for a Powerfull 700W Flex PSU, as an alternative to the famous ENHANCE 7660B although it's chinese.I did a few more tests with a 4020 / 5000RPM fan today. It's not a Noctua but has similar airflow characteristics.
I also have to correct my original post: the fan is temperature controlled. Here is my "guestimate" how the fan curve looks like:
I'm not sure where / how they measure the temperature but IMO the most important area is near the caps as they are the most heat-senitive part inside your PSU. As hotter the caps get, the sooner they will fail (see example below). So I placed a temperature probe in this area.
1st test: 30 minutes 300W load / 4020, 5000RPM fan / Exhaust (standard orientation)
2nd test: 30 minutes 300W load / 4020, 5000RPM fan / Intake
Interesting results. With the fan in standard orientation (exhaust) the internals of the PSU seem to get much hotter. So why is the fan on most FLEX PSUs exhaust? Honestly, I have no idea. I work a lot with industrial power supplies and most of them have the fan set as intake, pushing fresh air inside the PSU. For FLEX maybe they do it because of dust, fan turbulence (noise) or to prevent additional hot air is pushed in your PC... Anyways, guess they have a reason to do so.
