I'm building my own case and I'm going for as small as possible pretty much so I was wondering what SFX psu are good/safe.
My options are:
  1. Seasonic Focus SFX 650 143€
  2. Corsair SF600 138€
  3. be quiet! SFX-L POWER 600w 127€
  4. Seasonic Focus SGX 500W 109€

  1. is there any psu better than the other?
  2. Is the 500W enough for 1070ti + R5 2600 for overclock/upgrades in the future?

Also My system is:
R5 2600 + Arctic Freezer 34 Duo
16Gb 3000MHz
Msi 1070ti gaming x
M.2 256 Gb
SSD 480 Gb hyperX fury

As someone who owns an mITX system, trust me, you are going to want the best PSU you can get for the money and one that requires very little maintenance, especially if you're going to power any real GPU with it. I've found that Corsair generally makes the best SFX power supplies. You can't go wrong with Seasonic, either. But you want minimum 600W, but if you can get the SF650 or SF750, that would be the best.

On my personal mITX system I power a Ryzen 2600 on a Gigabyte Aorus A450 with a Radeon 5600XT, and I've found that 600W is more than enough power for this configuration but if you're going to overclock on top of that, I'd move to the 750.
One thing to note, only the SF600 is SFX. Seasonic SGX and Be Quiet SFX-L are both SFX-L, which means it is bigger than the SF600. The length of the PSU are: 100mm for SF600, and 125mm for SGX and SFX-L. Assuming that you are referring to SF600 Platinum, it is the best choice. If you are referring to the gold version though, they are about equal.
