Advice on upgrading PSU

[Theirry]

This is my first build (so Im still learning the basics) and first post on Tom's Hardware.

CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K

MoBo: ASUS P8Z77-V LK LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS (Referbished! Not sure if it was worth it, had to RMA it.)

GPU: MSI N660 Gaming 2GD5/OC GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 SLI Support Video Card

Memory: G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C11D-8GSR

CPU Cooling: XIGMATEK Prime SD1484 (CAC-SYHH4-U01) 140mm Sleeve Bearing (with copper axle) CPU Cooler

Storage: Seagate Barracuda 7200.14 ST3000DM001 3TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive (RMA'd because BIOS Wouldn't detect it.)

PSU:
Rosewill CAPSTONE-450 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire ...

I feel like I may have skimped out on the PSU, so I was wondering: Will I have problems with this current PSU and what Wattage should I be looking for in an upgrade?

(Had to RMA another part I received from NewEgg so I haven't even been able to try it myself.)

Any feedback or comments are appreciated.

that is a gold certified PSU, so they can pull out more power than laveled (maybe close to 600W), due to its quality components and efficiency, however you will be pushing too hard the PSU+12v rails, reducing the PSU lifespan considerably. The best option is to be as close to 50% from PSU load as possible, where the PSU shows better efficiency, and not close to 100% (as that 450W unit would be ).

Also, taking into account he has a 3570K CPU(even that he has limited OC potential due to air cooling solution, and mobo series) and the other componnents, I asume he will practice some OC activities on near future when he learn how to, so the max TDP of a CPU and GPU can rise considerably when overclocked.

You read my choices like a book sir, I will most likely purchase a 600W when I am able so I can learn how to OC.

Agree, so XFX is a good brand, they use SEASONIC topologies (made by SEASONIC,the best of the best).
Highly recommended.
