That PSu is junk. You want 500w from Antec, XFX, COrsair, Seasonic.

That PSu is junk. You want 500w from Antec, XFX, COrsair, Seasonic.

And with PSu you mean Power Supply Unit?
So i should scrap the MS-Tech, ok

I can't find any 500w PSu's via that Tweakers site though, you have any specific ones to recommend?

 

[tiny voices]

Anything from those brands I listed. 550w is fine too.

 

[Nhoise]

Anything from those brands I listed.

But like i said; there are no 500w listed of those brands.
Highest is 450w

edit: i went to look on a site that i know that sells computer parts.
ATX, SFX, FlexATX, PicoPSU and other are categories i can choose, does it matter for my setup?

 

[tiny voices]

With the parts you have listed AND overclocking, you really want 500w.

http://tweakers.net/pricewatch/322857/corsair-cx500m.html
http://tweakers.net/pricewatch/279914/xfx-pro-550w.html
http://tweakers.net/pricewatch/253418/seasonic-m12ii-520w.html

There are a ton.

 

[Nhoise]

Hmm yes, you are right. I don't know what i did wrong but i didn't see those listed.
Thank you, any of those would be fine with my current setup? as long as i go with atleast 500w min.

You see any other problems with my list?

 

[tiny voices]

I would get the XFX550 I linked. It is VERY good quality.

No I don't see any other issues.

 

[Nhoise]

I put a note next to that one, i'll see if there are other people with opinions about it. Thank you.
There were people who told me to get the i5-4670K in stead of the 3570K, would this be a good idea?
and the same goes for the SSD, i've been told Adata isn't one of the best things to get, is this true in your opinion?

Also which RAM would you recommend when choosing between the two i listed? and what about the MB's? is there a point in getting the G45 instead of the G43 in my case?

 

[tiny voices]

A-Data isn't the best, but they are by far not the worst. I would try to get a Samsung 840 EVO.

The 4670k is newer. You will need a z87 motherboard to go with it.

Either RAM is perfectly fine.

The G43 is a MUCH better board if you plan to overclock. The g43 won't really be good for it at all.

 

[Nhoise]

That's funny, i had the 840EVO listed first but replaced it with the Adata after 2 people told me so.

But if i would go for the 4670k i need to change the MB to a newer one as well, i'll have a look at how much that would increase the price.
Would you say that it would be a wise choice to change or is sticking with the 3570k and the G45 MSI just fine for what i want to do with it.
I'm assuming you mean that the G45 is a MUCH better board, but correct me if i'm wrong. It could be the other way around

edit: MSI Z87-G55 is offered for 114eu, that's not much of a price increase compared to the Z77A G45

 

[tiny voices]

Yes the g45 is a WAY better board. Sorry about that.

 

[Nhoise]

Ok then i'll take the G43 off my list
