I was supposed to be getting a 500W power supply with my case, unfortunately they didn't include it. Will my 300W tide me over until tomorrow when I go get it? I'm thinking not...
AMD Phenom X4 II 955
4 GB (2x2G) Corsair 1600 MHz FSB DDR3 RAM
Asus Radeon 5850 HD
Seagate 1 TB SATA HDD
LG Blu-Ray combo
Gigabyte 790XT-UD4P MOBO
Also, can you suggest me a good PSU to get for this system when the shops open tomorrow? Thanking you kindly
