I have a Gigabyte ATI HD 5770 Radeon 1 GB DDR5 and a corsair 450VX EU (450) PSU.
When I have a load running, like a game, for example Bad company 2 (running at Medium settings @ 1280X1024 res), I get big drops in FPS every once in a while and sometimes the PSU makes a clicking sound, similar to a hard drive searching.
Since I recently aquired both my PSU and GPU, I was thinking of exchanging (if possible) the Corsair 450VX PSU for a corsair 550VX will this help? Is the 450 fine in general and I just got a faulty one or do I need a more powerful PSU?
My comps specs:
Processor: Intel Core 2 Quad CPU Q6600 @ 2.40GHz
Motherboard: Gigabyte G31M-ES2L (rev 2.0)
System memory: 4 GB
Hard drive: WDC WD6400AAKS-00A7B0 ATA Device, 596.17 GB
I thought it would be sufficient ... but like I said when I run a heavy load like a game I sometimes hear a clicking sound like a hard drive searching. also I thought the reason for the intervaled drops in FPS in game was do to a lack of power...but I could be wrong.
