Hi,

As above, will a 550W PSU be enough for a i5-3570k CPU and GTX 560 ti GPU? I won't be doing anything too power consuming like overclocking...

Thanks!

What is the make/model of the PSU? A good quality 550W PSU with two 75W 6-pin PCIe power connectors and 32A on the 12V rails is sufficient for a stock GTX 560ti.

32a on a 550w ?
IMO a "good quality" 550w should have 38a or more available, and would be fine for all but extreme overclocking

A good 550W is likely to have even more than 38A like the 44a on the XFX Core 550W or the 40A on the Seasonic S12II-520W. I was simply trying to say that any PSU that is married to a GTX 560ti should have at least 32A on the 12V rails. I can definitely see what you're saying though: a 550W PSU with only 32A on the 12V rails is not indicative of a good quality PSU...

That is definitely not a good quality PSU and it doesn't have any PCIe power connectors. You should definitely get a new PSU. What's your budget and what site(s) do you plan on shopping?

Its this one lol, its really old... My guesses are that it won't be enough?

No offence, but yuk
A quick Google search shows what I guess is the latest model, with no pcie connectors ( not mentioned in your link either ) and a single 25a 12v rail

My budget is quite low, I'm planning to spend around $500-$550 to buy a motherboard, i5-3570k and a GPU around $200.

Could you guys recommend a good GPU around $200 (preferably less), a motherboard thats Z77 around $100-140ish and now a cheap good PSU for this setup?

Oh oops sorry about that, I'll be using newegg.com
I tried to find a shop in my country (Australia) but newegg seems to be cheaper and most of them don't have delivery fees haha :) 

Thanks again!

Newegg doesn't ship internationally, and the added cost if they did would negate any deals

Wll i run a Core 2 Quad Q8400 + GTX 560 on a Cooler Master GX550 PSU. Zilch problems. It's rated for 42A on the 12V.

Anyway, max power consumption i've seen on it with 80%+ CPU and 98% GPU load is 260W on the wall (measured using my APC UPS).

The 3570k has a TDP of 77W and the 560 Ti has a TDP of 170W.
The Q8400 has a TDP of 95W and the 560 has a TDP of 150W.

So yeah you'll be fine with a 550W. In fact, you could also use Seasonic's S12II-520 or S12II-620 models, among others.

P.S.That CX500 suffers a drop in efficiency if the ambient temperature is over 30*C, so i guess only get that if you have an intake for the PSU fan.

EDIT: I MEANT PSU FAN

ahh what is a good PSU then if I don't have any additional fans? All I'll have is the motherboard, CPU, GPU (and whatever type of fans come with them). Motherboard will probably will be the GIGABYTE GA-Z77-D3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard, CPU i5-3570k, GPU GTX 560 ti.

Haha I won't be needing memory and all, thanks for your help :)  I think I may increase my budget a little and get a gtx 560 ti, which I'm guessing is better than the 7850?

The 7850 is better than the 560ti, and if you are not going to overclock I would advise just getting the i5-3450 and save yourself some money :)
