New Components with current PSU

[Joe96]

Hi everyone,

I decided to buy new processor (i5 3570) and graphic card (gigabyte radeon HD 7870), however I have worries about if my PSU will be good with these.

So, my current PC will be:

Motherboard: ASRock H61M-S
Graphic Card: Gigabyte Radeon HD 7870 OC
CPU: Intel Core i5 3570
Memory: 2x 4GB Kingston

My current PSU:
MODEL: A-650BR
En60950
AC input: 230VAC 10A 50-60Hz
650W
A-650BR WEB LINK

ONLY IF
my PSU will not be compatible with these specs, please give me some examples of new one, where I can spend about 30 pounds, however PSU doesn't have to be "the best" just need to run all specs - that's my requirement.

your PSU isn't compatible as 7870 requirs 2x 6pin pcie, while yours has only one. get something like corsair CX500. not the best but should meet your requirments.

This PSU has only 500W, GPU needs 500W so it will take all of the power from PSU, what about motherboard and other components, I think that it should be around 600W or I am wrong.

@Joe96 no no no. you got that completely wrong. GPU uses 250W. what you probably read "minimum 500W PSU required" it means you need a atleast 500W PSU, so the GPU will take up 250W and leave 250W for CPU,HDD mobo etc.

Okay, I found one but I am not sure if this is what you suggested.

You saying it will be better choice, can you expand it little more for me?

CX series (original)
Cheap, budget-oriented units. Fixed cables, rated at 40C, mixed Japanese and Taiwanese caps, 80+, 3 year warranty.

CX400 - SeaSonic S12II (SS-***ES)

CX (v1) "Builder" series
Very cheap, budget-oriented units. Fixed cables, rated at 30C, mixed Taiwanese and Chinese caps, non-80+, 2 year warranty.

CX430 - CWT DSA-II (Note: unit is overrated, actually 380W)
CX500 - CWT DSA-II
CX600 - CWT DSA-II

CXv2 "Builder" series
Cheap, budget-oriented units. Fixed cables, rated at 30C, mixed Taiwanese and Chinese caps, 80+, 3 year warranty. Same as CXv1 but with upgraded switching components and +12V rectifiers.

CX430v2 - CWT DSA-II
CX500v2 - CWT DSA-II
CX600v2 - CWT DSA-II

And the one I mentioned is made by Seasonic the maker of top line PSU's. Solid build, good Japanese capacitors for long term reliability.

@lonewolf7 CX 400 is good but its out of production im afraid. but the XFX one you stated is quite reliable and is made by seasonic. so if it isn't too much on your wallet then id say go with XFX one.
