Well first of all I'm building a new rig, my previous rigs were all bought pre made from the shop so its my first time making my own. My general question is which PSU to choose. Also my second question is, will 500W be enough to power everything (look below for the parts)? Also which is better for my rig (again look below for spec), single rail or multiple rail? (I read about this on and seems the biggest difference is that the multiple is more safe, but what do you thing?)

So here's the 2 PSU's I can't decide which to pick:
Single rail:
Multiple (dual) rail:

So which PSU would be better for my rig from the 2 above (if 500W is enough of course)?
Thanks and soory because of the long text.

Rig spec:
i5 CPU
mobo gigabyte p55a-ud4
ati radeon 5850
1tb WB black harddrive
CPU cooler: still considering
nzxt m59 case
samsung dvd optical drive
2 additional fans for case

Best buy sells a BFG Modular 550W for 69.99 this week that you might wanna check out

Do they have Best Buy in Europe ?

Well I can't get that one in my country so if I buy from another country it would cost almost double.

Well overall what do you guys think which PSU from the two above would suit most for my rig?
