Hello,
A non-CM related but technical question, if you don't mind. I currently have an Athlon 64 3700+ CPU and 2GB Ram with a 7900GS video card and also an Antec 450W PSU with a 32A (15A+17A) rating on the 12V railings.
I am looking at purchasing an eVGA 8800GTS 320MB video card for my system, but was wondering if it is worth it and could my PSU easily handle the new card at peak loads. The specs for the 8800GTS card says that a 450W PSU with a minimum of 26A on the 12V railings is required.
My 450W PSU specs:
+3.3V +5V +12V1 +12V2 +5V SB -12V
Max. Load 32.0A* 30A* 15A* 17A 2.0A 0.3A
Min. Load 0.5A 0.5A 0.4A 0.4A 0A 0A
Load Reg. ±5% ±5% ±5% 5% ±5% ±5%
Ripple V(p-p) 50mV 50mV 120mV 120mV 50mV 120mV
* +5V, +12V1, 12V2 and +3.3V maximum output: 410 Watts max
* +5V and +3.3V combined output: 150Watts
* +5V, +12V1, 12V2 and +3.3V maximum output: 410 Watts max
* +5V and +3.3V combined output: 150Watts
1) Can my current PSU handle the 8800GTS with no issues? Or should I consider purchasing a more powerful PSU?
2) With my current specs, is it worth upgrading from a 7900GS to a 8800GTS with still a 3700+ CPU?
I have no desire to go Vista now or in the medium term future so I am not interested in the 8800GTS for DirectX 10 support, just faster performance.
Many thanks for any and all replies.
