sfx around 800w

[Dackzy]

So I will build a mATX build soon, the case I will use can support atx PSU, but I will mod the case so a smaller PSU can give me more space for my airflow. I will make a power hungry system so a 750w-800w PSU is needed and it needs to be sfx size.

what case are you using that the airflow is that bad? and what hardware are you using? only with a 5960x and two titans you need that much wattage

cf or sli the next two top models from Nvidia or AMD with a Zen or kaby lake. The case is a Styx classic, I will mod the front.

That isn't an SFX PSU..

but if you  go with the new top models - they will draw even less power

that depends on how much I OC and all the tdp on GPUs have been bs this Gen.

True, but it has the wattage that he needs and it is shorter. 800w SFX PSUs are not a thing yet

then I'd go with another case... not this one. Or go with a real short atx psu

@Dackzy The highest Wattage that you can get at this point in time (that I know of) for SFX is the SX700-LPT from Silverstone, 700 Watt.

 

Which honestly? It really should be more than enough for running SLI, even with some overclocking.

I can put a normal atx psu in it, but to get the most airflow in the front a smaller size psu would help. What is the shortest atx psu I can get?

140mm is the shortest I've ever seen. But why do you want this particular case for such a project? I think it is one of the worst cases you can get for such a project

nice thanks it is a long time since I build a PC where I just couldn't go out and get a ax series PSU and I don't really follow the PSU marked

You can get some insane airflow in it after the front mod were I push the front about 1cm out, me and my friend did some math about every second all the air inside the case would have be changed about 4 times. The case also looks pretty epic and I will also make a full Plexiglas side. I have found the fans that I will use even if I run them at half speed there will still be really good cooling in it and even at max speed it will be pretty quiet.

Here's an example of how power efficient these new graphics card are. Power is measures directly at the card itself, from the PCIe and the 8-pin.

I will most likely get 2x 490x and OC them and it is always nice to have more power than you need.

The only problem is that you might just to limited to 600 Watt for SFX, since I haven't actually found a place anywhere that sell the 700 Watt version of that power supply...

in the worst case I will get the shortest good atx psu I can find, but hopefully the 700w will be out when I really need it, maybe even a 800w will be out.

A normal length for ATX supplies is anywhere between 140mm for shorter ones, up to 160~170mm.

 

So a good candidate should be Cooler Master's V750, which is 140mm long, and still uses a 120mm fan.

Even for SLI, modern cards use so little power that the 700W Silverstone is way more than enough. If you want to SLI 1080s then a Corsair SF600 is good provided you don't overclock things.

Well I OC and I would never let the shitty 1080 inside my case.

"Shitty 1080.."

It's currently the most powerful consumer GPU, not sure why it's "shitty" to you.

it is just a moded version of maxwell with a die shrink and it does not have very good dx12 support.

....?

 

Like two games run in DX12 because it's super shitty and unstable for one, second of all, "Maxwell with a die shrink" can basically describe any generational upgrade going from one generation to the next.
