Build Advice Would a 500w power this set up?

This is my PSU atm >Micro ATX.

The set up is:

Gigabyte GA-H55N-USB3
XFX HD 5870 1GB
Intel Core i7 870 2.93GHZ
Kingston ValueRAM / 2GB 1333MHz PC3-10600 DDR3 x2

And a 500GB hard drive

EDIT: will not overclock anything

I'm gonna cram it into a Silverstone sg05

 

Barely, even though it says 500w it is only capable of outputting 324w (14A+13Ax12v) from it's 12v rails which should give you a little headroom but I can't find any decent reviews that will actually vouch for a Colours IT PSU.

If you do intend to use it i'd only use it for a short period of time until you get a reputable PSU.

 

I'd run from that PSU. Get a good Corsair or XFX one

 

But what good psu would fit in a SG05?? That's the only 500w I found.

 

There's a version of that case with a 450W PSU... Get that with a Geforce 460...

 

but i already have the XFX 5870 in another set up with a AMD Athlon x2 64 5000+ in the SG05. So im just wanting to upgrade to a new motherboard and a new CPU. The Micro ATX can power the things i have now. But will it power a i7 870?

 

Personally I wouldn't trust that one you linked too. Used this to give you an estimate of power

 

if your having problems craming this all in with a decent psu (which should be one consider as one of the most vital parts of your build, never skimp on the psu) maybe try looking at a larger case?

 

A Silverstone 450w ST45SF SFX should power it, mars-bar-man installed one in a mini-ITX build with a GTX460 here: http://forums.bit-tech.net/showthread.php?t=190391.

Scan have them for £62.24: http://www.scan.co.uk/products/450w...r-80-plus-bronze-85-eff-18db-eps-12v-80mm-fan.

Saw those on Scan. Bloody expensive, make my Revolution seem like good value for money...

 

Ignore that Pete, I got that link wrong, see my later edit. The Seasonic isn't SFX form factor.

 

The mATX PSU I'd get would most likely be this:

With the key difference being that this one comes from a respected brand, is reviewerd, and most of all is capable of 432 W to the 12V line.

 

I agree with Jipa on the PSU chose, as others have said, dont skimp on the PSU, it is the most important part of the build.

I am silverstone fan, they make great kit esp. for HTPCs.
