Corsair 550W VS or 650W CS PSU

[Guest]

I'm ordering a PC I've configured from PC specialist (I can't build one ATM) and I've got a choice between Corsair 550W VS or the 650W CS PSU is it worth spending more on the CS and will I need the extra wattage? I'm not planning to overclock or add Sli or Xfire. Will they both run my system stabily? I'm going to be using it for rendering and recording minecraft if it helps. Many thanks

The Corsair CS650M is definitely a better and more modern PSU. It is based on a modern DC-to-DC circuit topology and is Intel Haswell Ready. It uses better quality electrolytic capacitors and has better voltage regulation. Semi-modular output cables are nice.

The Corsair VS550 is based on an older group regulated design that is not Intel Haswell Ready. Voltage regulation is not as good. Much lower quality parts are used in its build. All of its output cables are hardwired to the PSU.
