is 550 watts enough for these specs?

Welcome

Almost definately no, but to be sure, what PSUs are you considering?

 

[daisymtc]

550W should enough, but depends on brand

 

[Okedokey]

It has nothing to do with wattage. OP, please state which PSU you are using, but almost certainly a 550W Psu will not provide sufficient amperage on the 12V rail, particularly if it only has ATX design standards.

 

[maverick911]

i have the ultra 550 watt and thinking of the 750 watt ultra psu. note: my gpu takes up 450 watts of power

 

[Okedokey]

I would go for a Corsair 750W to give you upgrade room.

550W should enough, but depends on brand

XFX recommends min of 620watt with 35AMP min on 12volt rails for a start...

 

[maverick911]

so please reccommend a good *affordable* power supply

as above

I'd say the Corsair 750 watt would be an overkill. Maybe the Corsair 620 or 650 watt PSU. Eitherway, I doubt that computer would pull over 500 watts of power.

 

[Mitch?]

to be honest i think the psu would work
my system is on ya 550w Rosewill right now, and works fine, even with the overclocks, my extra hdd, and more fans than yours.

 

[Okedokey]

Its not about wattage, more about the 12V rail amperage and efficiency, and btw Rosewills are a POS!

 

[WeatherMan]

Corsiar 520 would run that fine but you'd want some futureproof-ability, so go for a 650

I'm sticking to my original statement. my $50 rosewill has powered the current computer for 6 months now. The computer before this had Rosewill 400w, and that's lasted 2 years no issues.

 

[Kornowski]

I think it'd be fine. I'm running my sig rig on a Corsair 520!

If you get a good quality 550W unit, you'll be fine. Sure, you won't have a ton of leeway for future upgrades, but for your current specs, it'll handle it no problem.
