The PSU is a possibility. The one you bought has 17A on the 12v rail. Mine has 60A on the 12v Rail!! The 12v will power most of the PC, so it is important to have a lot of power there.
Sometimes though, it could be a bad component as you stated. Someone else had a similar problem and it turned out the RAM was bad.
If there is a place that you can buy a part and return it like Walmart or something, see if you can buy a PSU and test out the system. If they don't carry a reasonable brand, get a high wattage one. If the new PSU works, take it back and say it doesn't fit. Then return the Seasonic one and get this one:

I think regardless you should swap the PSU for the Corsair one.
If the PSU does not solve the issue, then it may be another component or something wrong installation wise. The only way to test components is to swap in components that you know work and see if it solves the issue. You do this one at a time to single out the problem component.

Actualy, his new power supply has a pair of 17A @ 12v lines.
The ATI 4830 REQUIRES 19.9A @ 12V...And that model card only has one power input.
One of my old cards came with a splitter that allowed you to power it from 2 seperate 12v lines, but I think you would be better off with a better power supply. If you wanna be green, there are better units available anyway.
BTW: Power supplys "burn in" over the first few months of use. It may start as a 400W unit, but after burn-in it will be closer to 375W. Do yourself a favor and buy a little bit of overkill, I'd go with a good quality 600W or higher...The W rating is the maximum; it uses less power when the system does not need as much.

Oh, I see. I thought that 17A was not enough, but this is 17x2. Either way, you are better off with the Corsair. It will definitely supply 450 watts of power and has 32A on the 12v rail. This is enough to power your system.
What KillerBug says is true though. A larger PSU will not hurt your system. I have a 750 watt PSU to power my system and probably a 450 watt would have done. However, it is more important to go with a good brand than more wattage. Cheap PSUs generally output 1/2 of the wattage claimed. That 450 watt Corsair will output 450 watts no prob. Also, these High Quality PSUs have no problem outputting at full load, so they will not blow if the PC draws a lot of power.
If you want to higher wattage PSU, stick with Corsair. Pay a little more now, save a lot later (in energy costs and component life).
Start with the PSU and then troubleshoot the other components.

Thanks a lot for the replies guys. I was having doubts by replacing the PSU myself, but you just replenished my confidence.
Right now i can`t make any moves as all the shops are closed for New Years day. I`m planning on dropping by a local CanadaComputers as soon as i can rather than ordering another PSU from newegg (can`t handle the wait of shipping any longer!). And i`d like a bit of advice as to which brand to get.
I`ve noticed that theres this wonderful BFG 800W PSU on clearance ( http://www.canadacomputers.com/index.php...&cid=PS.808.978 ) and was wondering if the BFG brand is well worth it and if it's recognized as a good PSU manufacturer.
There`s also this Corsair 650W model ( http://www.canadacomputers.com/index.php...5708&cid=PS.808 ) which also seems to stand out of the other Corsair deals available.
I`m probably leaning towards the Corsair model as the BFG does not specify the Amperes for the 12V output.
I`m also a bit puzzled by the description for the BFG model which also contributes to the favour of Corsair.

1 x 20+4-Pin Motherboard Connector
Does that mean that this connector can serve as a 24 or a 20 Pin?

20+4 means it is a 24 pin adapter that can be split into a 20 pin and a 4 pin, so it is compatible with both 20 pin motherboards and 24 pin motherboards.
The BFG has 4 12v rails. It has 20A each. The Corsair has 52A on the 12V Rail. Get the Corsair. It is cheaper and better both in quality and power.

Agreed, Corsair is great stuff, it will probably outlast the rest of the system.

Well i've returned with my sexy looking PSU (it even came with screws, a nice bag around it, and even plastic laces to tie down the wires together!) and hooked it up to my system.
Sadly the same problem persists; it doesn't even boot. Even so, i plan on keeping the Corsair and shipping back the SeaSonic.
To save myself the hastle i'm going to have the gentlemen down at CanadaComputers run a system diagnostic on my build tomorrow in order to isolate the problem. Another thing i'd like to note was that the Mother board was strangely bent (but only slightly) when i tried to hook it up to my case. It didn't lie down flat, so i'm guessing that the mother board might have been at fault this whole time.
It'd be interesting if the motherboard was the faulty part since GIGABYTE flaunts that it's "Ultra Durable 3" (on the cover of the box).

Do the following:
Unplug everything (leave your CPU in, and keep the motherboard plugged in)
Reseat the RAM (take it out, put it back in)
Reseat your graphics card.
Do this, and see if you get a picture on your screen. If you do, plug some more things in, and if the problem happens, unplug those 1 by one.

You have actually plugged the 4-pin CPU power connector into the motherboard right?
