SFX-L for 4090/5090

[Andrew Moore]

As title really, is there anything out there that runs the "new" ATX standard that will happily run that power draw of a card along with the usual couple of m.2s, an ITX board, 64GB of ram, larger draw AIO and an undecided CPU (think 9950x3d should this get announced at Computex).

I'm buying a few bits here and there now and migrating to a new ITX case that can take a 4 slot. Ive got this form factor now so figured I would start with a larger storage m.2, the case, potentially the cooler if mine doesnt fit (EK 280) as well as the PSU. Then all I will need to do is transplant the MB, RAM, CPU and new m.2 OS drive. Ill add the new GPU as and when it is released.

So PSU.. What do you think will fit the bill?

For context, i have an Corsair SFX 750w that uses the older ATX standard and the traditional ATX PCIE connectors.

Does it have to be SFX-L? I'd probably just try what you have if it has enough PCI-E 8 pins for the octopus adapter, or can take Corsair's 12VHPWR cable.

For the sake of about £120 or so I think I’d be better buying another just because I know that 750w is on the edge of what is recommended for a 4070ti never mind anything more juicy. I need to realistically work out the draw over all components as a worst case based on the power hungry parts of today and just hope that not much changes between generations.

I could try the old PSU, worst case I can run the old GPU for a day if the new one proves to be a problem as I wait for a new PSU to arrive I guess.

I have been running a 4090 with a 13900k with dual pump and 8 fans on corsair sf750 sfx without issue.

Christ! Really? That’s interesting I must say.. undervolting involved?
