Hello Tom's Hardware! I recently built a new computer using some of my older computer's parts in the process. Unfortunately I think the PSU is dying (My motherboard lights up, but I can't turn on the PC itself; System instability when turned on; Fans light up for one second and then the PC dies) so I'm in store for a new PSU

My present build is:
Intel(r) Core i5 Quad Core 4460 3.2Ghz @ 3.4ghz
Corsair Vengeance 8gb DDR3
320Gb WD HDD 5400RPM 2.5"
Deep Cool Ice Edge Mini FS
Palit GTX 650 1gb OC edition
ASUS B85M-G

I currently have my eyes on the FSP Raider 750W 80+Silver. But there's a 650w variant at a cheaper price. Will it suffice?

My budget is in the $70 dollar range but If anyone can suggest a better PSU for me at a cheaper price I'd be truly grateful.
