Looking for a Flex 350w PSU

[Hellfromabove]

Looking for a Flex 350w PSU. Computer specs:

Mini-ITX
i3-9100F
2x 4GB Ram
GTX 1050 LP (no dedicated power needed from PSU)
m.2 nVME SSD
Cooler Fan
2x Case fans
Max 8x USB or SSD devices at once

I've tested Zumax and R-Senda. I've seen the reviews here on JG, but the units that I have seem to be quite different and function decently compared to what has been reviewed here. However, I have seen a few that just don't work out of the box or work for some time and end up failing. If this was a beefy gaming rig, I'd probably be a bit more weary.

It would help if you listed stores you're shopping from and/or your country so we could look around for you. It's not always to flat-recommend a unit as in your country the price might be twice something that's only a notch lower in quality.

Just off the top of my head, the units to look for are:
Silverstone FX350-G
GeekStore Custom 350w (Either a Delta or Enhance unit, you get to choose.)
Seasonic M1U 350w
FSP FlexGURU 300w

The only major downsides to consider between those units is the Silverstone doesn't have modular cables, so you're somewhat stuck with what you get and the FSP unit is only 300w, not 350w. Should be more than enough for your specific setup.

I don't recall jonnyguru.com ever testing Flex ATX PSUs from either Zumax or R-Senda. We've tested those BRANDS in the past, but just because an ATX PSU is made on way doesn't mean a Flex ATX PSU is going to be made the same way with a different orientation.

That said, both Zumax and R-Senda are known garbage. This is why they keep dying.

What is a Flex ATX PSU?

What is a Flex ATX PSU?

It's a small form factor PSU. It's like a mini 1U. Not as long as a 1U PSU and has a standard ATX cable set instead of a card edge connector.

[Hellfromabove]

Hey guys, thanks for the information so far. The Delta and the Sea Sonic seem to be right up my alley. I remember hearing some great things about Enhance and it seems that JonnyGuru has reviewed that brand in the past (just not in a Flex ATX form factor).

What about the amount of power needed? Do you guys think 350w continuous will be enough for the build?

OK. What does a mini 1U look like? And it has a card edge connector?

[Stefan Payne]

its a small brick like thing that often comes with a 40mm fan. Basically a half height TFX PSU.
And due to its small size, the max. Power is limited to maybe 400W with modern Gold and Platinum Efficiency level due to the lack of airflow from the 40mm fan.

Thanks. And the edge card connector?

Oh, sorry, was talking about the Flex ATX PSU.

Here some Pictures of 1U and 2U PSU but without the edge connector:

The Edge Connector is a standard PCB to Connector type thing. They use a Standard Connector type that's been around forever and was also seen in ancient Gear as well.
