so looking to change my case to allow my 570 and a better psu to power the system, would a 450w be enough? like the silverstone v3 models for example?

i was going to test out my 500w atx aerocool unit, but it doesnt seem to have the required 8 pin and the case im thinking of is the Nano S.

Either of them should be fine but the newer version (ST30SF v2.0) would be better as it has the full 300w available on it's 12v rail compared to 264w on the ST30SF v1.0. The v2 has a 92mm fan compared to the v1's 80mm fan which was very noisy.

***Edit*** I just had a look at a review for your case and it appears that it uses the psu as the only exhaust. Not only is this poor practice as it will make the psu and a low profile cooler fight each other for air, but it will also mean that the psu fan will be running faster (and noisier) than it would otherwise need to. What I would do is turn the psu so it's fan is sucking cold air through that big top vent and as it looks like a fan can be fitted in the front of the case I would fit one there as the exhaust.

That's 120W card at most.

So well enough for that PC, assuming it's in good shape and not very old.

okay cool thanks, i know i posted my sfx once before, but cant remember the version ha and well the aerocool unit was purchased to make up the sig system to sell, but its an atx still, if the sfx wont be a risk then i will try it, i wouldnt be overclocking even if i could use my 570.

as for the case orientation for cooling its not great, but air blowing out from the gpu side, the psu doesnt spin as its never hot enough and the rgb fan ive installed lets a little out, but its an intake, so its pushing air out the sides.

thanks for that, but is that the exact same version? as when i google it, the sc gaming comes up, but this is just a sc model from the impressions i get.

Another bonus with the fixed cables on the Silverstone SFX is that you are gaining extra space from not having the modular cable plugs so will be able to have tighter cable bends from the psu.

The Silverstone SFX will be fine for your pc. I have posted this many times on here but just to give you a rough idea of power consumption, I am running a BeQuiet Straight Power 11 550w psu in the pc in my siggy along with 12x 120mm fans, 4x 200mm fans, 2x fan controllers, 2x Temp monitors and a couple of leds for the reservoir. It only pulls 128-275w at the wall while gaming (depending on the game) and the very max I have managed to make it pull was 367w at the wall while using OCCT's psu torture test. Idling/ internet browsing is 68w at the wall. Your pc won't pull that much power especially if you are not overclocking.

Your gpu fan is sucking air in from the side and dumping it out the rear of the case so I doubt if it's contributing to expelling hot air from the case very much.

Okay thanks for the reply, good to know of the assurance the psu will work, I do find it ironic how modular units are a god send which is why I have one, but only if you got tower cases, but yeah I won’t be overclocking, doubt I would need to, maybe the 950 for fun, but I wouldn’t use a 300w unit for that either, so I’ll put all this to the test tomorrow.

I’ve posted some pics in my thread in the gpu section, got my 570 to fit, but taking the plate off lol, however the card is too tall to allow the drive bracket and the psu is too big with it to cable manage, so it’s a good job the sfx will work with the 950 and go that route for the time being, damn these small cases ha.

Oh right okay it didn’t feel like the fan was sucking air in as most the air was going out that side with I guess whatever the front fan was sucking in pushing it out the other side vent, as the computer is apart I will turn the fan round so it blows out, other than using the system to run superposition with the case open and the 570 in, the computer wasn’t as near as warm as it was with the 950 and lid on, I haven’t begun to game yet though.
