450w psu enough

[thob30]

Hy there,
i'm going to build a new pc in little time:
ryzen 7 1700
trident z rgb 16gb 2400
1tb seagate barracuda
128gb plextor m8seg
gtx 1070(mamaybe 170ti)
and as it will be in the phanteks enthoo shift, i'm gonna need an sfx power supply, but they are quite pricey. I was wondering if this (https://www.newegg.com/global/it/Product/Product.aspx?Item=N82E16817256176&ignorebbr=1)psu would be enough to power up the system.
Thanks

That would be just enough for an OCed 1700 (~100W)+GTX1070 (~180W) + other components; a GTX1070Ti ~230W would make for a far too tight fit for when the system is under load and lower lifespan of the PSU. Being a small SFX size, running it at close to maximum load is not recommended as it would require its smaller fan to work harder and the fan is usually the first component (of a good PSU) to die.

Summary, it can work but I don't recommend using it with card of 1070Ti/1080 level of power draw.

so what shoud be the minimum?

A 450 is enough but just not the Silverstone one IMO.

Look at the corsair sf ones , the 450 if you're running a 1070 , the 600 if you were going for the 1070ti.

These are real tip-top quality units.

The 450w would actually manage a 1070ti fine IMO but the fan would be running heavy at 80%+ load & not particularly quiet.

The 600 has a semi passive mode which would make it virtually silent with those components.

& yes they're expensive but that's the price you pay going with a sff case at the end of the day.

 

[thob30]

so its COMPLETELY safe to go 450w with the gtx 1070?

 

[madmatt30]

Yes but I'd spend the extra $30 on the corsair sf450 - its far far far better than that Silverstone

 

[thob30]

thank you really appreciate your help

 

[thob30]

sorry for reopening this thread, but i have a doubt. Would that psu also handle a rx 580?

 

[madmatt30]

So long as you didn't go silly overclocking (which I wouldn't in a case like the shift anyway & you can't really because both the ryzen & the 580 have rather limited oc capabilities) then yes it would.

I would consider going with the ryzen 1600 though over the 1700 in all honesty , for gaming its virtually the same but runs a lot better temps than the 1700 on the stock cooler)

 

[thob30]

thank you a lot for your exaustive and quick answers. Though i will stick with the ryzen 7 because i'm gonna do lots of editing and 3d modeling.

I was gonna say you can also get a CX450M PSU but the one madmatt30 suggested is no doubt a better choice.
