Lenovo H430 PSU and GPU upgrade

[MouseOne]

I'm about to buy:
[strike]- Pulse 500W PSU ATX 12V Active PFC[/strike]
- Gigabyte GeForce GT 710 2GB DDR3 VGA Dual-Link DVI-D HDMI PCI-E Graphics Card
- Intel Core i5-750 8MB 2.66GHz LGA 1156 CPU Processor SLBLC

My question is if these will fit/work with my Lenovo h430 (mahobay motherboard) PC.

Putting a dangerous PSU in your system is not what I'd call an "upgrade".

First off why are you buying old hardware? A modern Intel CPU's integrated GPU is quite better than the GT 710.

I dont want to spend fortune on some old pc, i just wanted to refresh it a bit on low cost.

How much are you actually paying for this stuff?

psu is about 20 quid, gpu 40 and cpu is about 30

EDIT:
Any recommendations on picking psu and cpu?
