Add $100 US to the system price since the OS wasn't included in the cost. And note, video card requires a minimum 500watt power supply and they used a 450watt.
Well you must not be up on your PSU's, so here's a couple of examples (one good and one bad). All PSU's are not made equally.
*** Both reviews were performed by JonnyGuru.com, so you will have similar testing methods (in order to minimize variables).
*** Conclusion and Scoring:
Page 5 - Scoring
Performance (40% of the final score) - let's come up with some scoring now, shall we? This shouldn't be too tricky. We have that better than 1% average regulation, so no points come off there. I'm passing it for Gold, so no points off there. Where I do have to make a deduction is ripple suppression. I have no problem with the minor rails, but the 12V rail isn't quite as good as I want to see from the really elite units. At the 50mV mark, give or take a few millivolts, I usually remove half a point. So, I do believe we're going to see a 9.5 here.
Functionality (20% of the final score) - here, we start off with an automatic full point deduction due to the fully hardwired cables. No exceptions, I'm doing that for everyone these days. Normally, I'd be removing some more pointage for the PCI-E cabling as well. We have only one six pin on this unit, while the unit's capacity is right on the edge of being able to handle the slightly more power demanding cards. That said, I'm going to let it slide, this time. Like I said, it's right on the edge and you really should be looking at the 400W and up range to power one video card needing the kind of power that requires the 8 pin connectors. So, I guess I really have no more complaints, here. The cables aren't too long, there aren't too many of them, and I really like the shallow depth of the unit's housing. Let's do a 9 here.
Value (20% of the final score) - thanks a lot, Seasonic. I was taking a drink of Coke when I saw Newegg's $59.99 price tag, and now my nose is on fire from the inside out and my keyboard really needs cleaning. Good grief... sixty bucks for this kind of performance? You've got to be joking. Yeah, you can find much more powerful units there for the same money. But look at those units... many of them are much cheaper designs that don't have a hope in hell of matching the numbers this wee beastie can manage. That said, the price is just a tad on the high side. But only a tad, and the performance more than makes up for a lot of it. 9.5.
Build Quality (20% of the final score) - Seasonic's upped their game when it comes to build quality recently, and it shows in this unit. I can't fault anything about it. 10.

Summary
Seasonic has really been getting things done lately. First, the X series came and impressed. Then, the X series broke the 80 Plus Platinum barrier and impressed again. Performance was tweaked, resulting in huge 1250W units with near perfect regulation and ripple suppression. Now, they've taken everything awesome about those bigger units and downscaled them into smaller and more wallet friendly units. Is there room for improvement? There always is, yes. Does this unit need improvement? Nope. It's already a better supply than anything else at this power level I can think of right now.
The Good:
Gold efficiency
outstanding voltage stability
shallow housing
very good ripple suppression
The Bad:
I wanted to complain about something, but Seasonic didn't leave anything to really complain about
The Mediocre:
is there any real competition for this unit?
*** Conclusion and Scoring:
Performance (40% of the final score) - on one hand, there's really not much to get excited about here. The performance of this unit was exceedingly bland by my standards. Regulation was just ok. Efficiency was just ok. Overshoot transient testing showed merely average turn on spike suppression. But there are two things that really stand out at me. First, this unit could use some more ripple suppression. No matter which of my two review samples we talk about, ripple on the 3.3V rail went out of spec, and I have to consider that in the score. Since my original sample has been repaired and is again outperforming the second, I'll give Seasonic and Arctic Cooling the benefit of the doubt and go by the first unit's scope shots here. Out of spec is still out of spec, however. The second outstanding factor I want to consider is how well that first unit performed with only one 12V output part soldered in. Can't ignore that either, because it means that the 550W peak rating should be attainable. I wouldn't do it intentionally, because the wiring is a little thin gauge for that, but it's possible.
So, since this unit seems quite average in performance, I'll start out with a middle of the road 5. One point comes off for ripple. One point goes on for good design. What's that spell? F-I-V-E. Fair enough? I think so.
Functionality (20% of the final score) - there are some rather questionable decisions made by the Arctic Cooling crew here. First, we have cabling so short you will likely need a small case to house this unit in. Second, why an ATX12V but no facility for EPS12V? Many boards need such a connector these days. Third, the PCI-E cables are all differing lengths. And all the SATA connectors are on only one big long chain. What for? And what's up with the wiring to the fan? There has to be a better way to get power to it than that long cord that runs down to the main cable exit and into the unit. That said, there are some cool things going on here. We have a couple of fan only connectors, which is unusual in units these days. We have that F8 fan, which really is a quiet son of a gun. And we have enough PCI-E connectors to power two cards, even if the unit itself may not be able to take the most power hungry models. I think I'll go average again here. 5.
Value (30% of the final score) - since I cannot find a vendor in North America for this unit, I'll go by the MSRP for it which is $93.90 US. Yeah... ninety-four bucks for average 500W performance? I don't think so. This might start to compete at twenty bucks cheaper. 4.
Aesthetics (10% of the final score) - this unit is quite good looking to me, aside from a few obvious flaws. First, that blister packaging is not doing the unit any favors. Arctic Cooling would do well to toss the units into a bag before cramming them into a hard plastic finish marring shell. Second, I don't care for the kludgey look of the fan's power wires. Just drill a hole next to the fan and run the wires into the housing there, please. It'll look a lot neater and cleaner. 8.

Summary
Average power supply is average.
The Good:
looks good
silent
handles hot boxes well
decent regulation
lots of PCI-E connectors for the power level
has two fan control connectors (use low power fans on these)
The Bad:
not a 550W unit as implied by model number
thin gauge cables
all SATA connectors share one long chain
high MSRP
fan power cabling
The Mediocre:
3.3V ripple suppression needs a fair bit of work
So to put it lightly, do your research before you make accusations/statements about PSU requirements. I'm not an expert, but I try and make informed decisions about the parts that I buy. I have been bitten by cheap (not well made) PSU's in the past. You can have issues with better made PSU's too, but they will be warrantied better and will have a smaller tendency to fail than lesser quality ones.
