PSU Supplying Enough Power?

Hi,

I have this as my current spec:

COOLERMASTER SILEO 500 QUIET MID TOWER CASE
Processor (CPU) AMD PHENOM II X6 1055T (2.80GHz/9MB CACHE/AM3/)
Motherboard ASUS® M4A87TD/USB3: DUAL DDR3,SATA 6.0GB/s, USB 3.0
Memory (RAM) 4GB SAMSUNG DDR3 DUAL-DDR3 1333MHz (2 X 2GB)
Graphics Card 1GB NVIDIA GEFORCE GT430 - DVI,HDMI,VGA - DirectX® 11
Memory - 1st Hard Disk 1TB SERIAL ATA 3-Gb/s HARD DRIVE WITH 16MB CACHE (7,200rpm)
1st DVD/BLU-RAY Drive 12x BLU-RAY ROM DRIVE, 16x DVD ±R/±RW (£49)

This is my PSU

Power Supply 450W Quiet 80 PLUS Dual Rail PSU + 120mm Case Fan (£29)

I want to buy a XFX radeon 7850 1gb or 2gb, will I need to upgrade my CPU, they say minimum of 500w, but not sure if my system is eating up that much.

  1. Now the psu is enough.Upgrade to 7850 or use both gpu means u r psu not enough.
    "Asus wats calculator" give more info to u.
  2. we would need a PSU brand/model. gut says its probably not capable of 450W and replace it
  3. I'm guessing that the PSU is going bad and is starting to show it's signs. What brand of PSU do you have?

    * I would consider upgrading your PSU to at least a 450w-550w quality PSU. Made by Antec/Corsair/Seasonic/PCP&C to name a few.
