Will the Radeon HD 7750 1GB GDDR5 work on 12v1 15A and 12v2 18A rails

[payawal_franz]

My old card which is the GeForce 9500 GT died on me yesterday so I I was thinking of replacing it with Radeon HD 7750 1GB GDDR5 but do you think it is capable of running it with my pc's power supply?

Here's the specs of my pc though:
Aspire 600W power supply
ECS GeForce6100PM-M2 AM3
1TB HDD
AMD Athlon II X2 240
2x 4GB DDR2 RAM

Here's the voltages and current of my power supply:
+5V-25A, +3.3V-25A, +12V1-15A, +12V2-18A, -12V-0.5A, +5VSB-2.5A

The specs of my computer may be old but I also plan on upgrading my processor soon though.

I'd get rid of that PSU. It's not what I'd keep in my rig. Rather a quality, robust unit that is as close to Tier 1 as possible. Arguably you can run off a 350W PSU but that unit is dodgy to say the least.

well laws of calculation of wattage say The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
so for 15a x 12v = 180w and 18a x 12v = 216w

the HD 7750 according to https://www.anandtech.com/show/5541/amd-radeon-hd-7750-radeon-hd-7770-ghz-edition-review/23 need anywhere from 100w to 216w underload. So in theory, your PSu can handle the video card yes.

though it all matters on quality as its almost at the top most range your psu can produce.

Oh ok but which is better or faster between the two video cards, the GeForce GT 730 2GB GDDR5 or the AMD Radeon HD 7750 1GB GDDR5?

7750 is a stronger card.
1gb vram now days though is cutting it close.

That said coming from a 9500gt which has 512mb or 1gb vram depending on model , the7750 is a substantial upgrade to What you are used to.

So do i still get the hd7750 even through the vram is 1gb unlike the gt 730 which is 2gb. I only plan to play games at low-medium settings
