I think I need a better PSU

Hi, I recently built my first computer with parts I ordered from newegg. I was so thrilled when it started up. Very quickly however I realized something was wrong. I tried to load skyrim but it froze almost instantly. I ran various tests and was sure it was my gpu. Then I started to get a series of crashes and messages that the display driver had stopped working but repaired itself. I'm not sure if it's because the psu is insufficient or if it's a gpu problem. This is what I've got set up.

CPU: Intel Core i3-4130 Haswell 3.4GHz LGA 1150 54W Dual-Core Desktop Processor Intel HD Graphics 4400 BX80646I34130
GPU: PowerColor AX7770 1GBD5-DH Radeon HD 7770 GHz Edition 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
Memory: Team Xtreem Dark Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model
HDD: Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive
MOBO: ASUS H81M-A LGA 1150 Intel H81 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
PSU: SeaSonic SSR-360GP 360W ATX12V v2.31 80 PLUS GOLD Certified Active PFC Power Supply New 4th Gen CPU Certified.

I checked out power supply calculator and it shot back that I'd need around 450W, rather than 360W. I was just looking for some sort of feedback, whether I need a new PSU, does anyone have a good recommendation? Thanks a lot.

Edit: Would something like this work? Is it compatible with the mATX board? http://www.canadacomputers.com/product_info.php?cPath=3...

I think its you PSU I would recommend 500w min for that rig hang on give me 15 mins or so I will check your system power requirements

OK your PSU should be ok but have you over clocked anything a water cooling loop or any devices running off your computer that you have not listed.

I forgot to add that I've got a dvd-rw drive. But I figured that doesn't take a huge amount. It's not overclocked, no water cooling. I thought it would be ok as well. I'm stuck in this is it the GPU or PSU web. I'm thinking I might go pick this up today and see if it has any effect. As far as I can tell it should work with what I've got. http://www.canadacomputers.com/product_info.php?cPath=3...

Yes , the Corsair you linked , is more than enough power to run your system.

For a system using a single Radeon HD 7770 GHz Edition graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 23 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Seasonic G Series 360W (SSR-360GP Active PFC F3) power supply unit, with its maximum combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connector, is sufficient to power your system configuration with a single Radeon HD 7770 GHz Edition graphics card.

An Update:
I picked up the 500Watt Corsair and installed it. I still get the same errors I was getting which leads me to believe that it is the GPU. I pulled the GPU out and was no longer getting the same errors. I think I just ended up with a faulty GPU. I'm gonna swap the powercolor for an asus. Still an HD 7770 and try both power supplies. If I get it working with the Seasonic I'm going to send return the Corsair and RMA the powercolor.
