do you recommend me upgrading the psu to 585w hec X orion?
LOL, no. That PSU is as bad (or worse) than the one it comes with. I actually have that HEC unit in one of my builds that I don't care about, and it's the worst pieces of junk that I've ever owned. VERY lightweight and the voltages a VERY unstable.
If you're going to get a better PSU, go for SeaSonic, Corsair, Antec, PC Power & Cooling, XFX, or Silverstone. Almost all units from those companies are great quality units that you'll never have a problem with.
Yes, units from those companies are more expensive, but there's a reason for that: Quality. The PSU is THE most important part of the system and you DO NOT want to cheap out and go with junk, just to save money. It's not worth it because when a bad PSU dies, if it dies catastrophically, it can take out other components in the system with it. Just too risky.
