Hey Everyone, I've got a PSU question this time round. I just built myself a new computer with an: AMD Phenom II x4 955 Black Edition 1 Sata 2 HDD 1 DVD/RW drive MSI 890GXM-G65 Motherboard 2 X 2GB of 1333mhz ddr3 ram 4 120 mm fans 1 140 mm fan Soon to be: 1 ATI Radeon 5770 GPU I got the case and psu in a combo pack since it was cheaper and I originally had intended to use a much worse graphics card. The PSU included with the case is an Antec BP430 (I know its not the best card) which is supposedly 430 Watts. To run this set up I was wondering if I will need to get a new PSU. The options for such are: Use the current PSU Get this PSU (Newegg.com - Pixxo PW-600EQE 600W Power Supply W/ 110V US Type Power Cord) Use my old Logisys 550w PSU (Newegg.com - LOGISYS Computer PS550ABK 550Watts ATX12V Power Supply With SATA and 20/24 Pin connectors.) If you guys could help me out on this one it would be great. I know none of these solutions would be optimal but that Pixxo 600W psu I can get for 20 bucks today, so I would just like to know if I should act on it. I'm not worried about stability too much, in terms of name brandage. I had been using that Logisys PSU for 4 years on my other desktop (I have a 3 month old one for the new computer if chosen) and never had a problem (ran 2 SATA HDDs, 2Gbs of ram, 2 Disc Drives, as much as 15 fans, an AMD Athlon x2 4600 and an Nvidia 7900gt ko graphics card. Any help you guys can give me would be greatly appreciated!
