Hey guys, first time poster here. I've been going insane trying to find a straight answer to a question I've had for the last few days. I'm sure this one has been asked about a million times already so my apologies in advance.
I just bought an XFX Radeon 4770 and I'm wondering if my current PSU will be enough to power everything I have in my machine plus the new card without any issues. The card has not arrived yet and I wanted to be sure I was going to be okay before I threw it in.
I'm using this power supply at the moment: http://img137.imageshack.us/i/budgetpower3.jpg/.
I've heard that 400 watts is enough to power the card on a mid range system but you need at least 20-25 amps on the 12v rail. I have honestly not paid much attention to anything other than brand and wattage when it came to power supplies until recently when I began to rebuild my old AGP machine from the ground up. I have not had the money to upgrade the PSU yet so in looking for an answer to this question, I found I had no clue about the rail amps, what they power, and if I would have enough wattage/amps for the card on top of my current components.
Since I don't know what specs would all be needed to form an opinion on if my PSU is sufficient, I'll just list off the basics:
AMD Athlon 64 X2 5200 Brisbane w/stock HSF
Biostar TF720 A2+ Mobo
Corsair XMS2 2GB DDR2 in DC (2x 1gb)
WD Caviar Black 500GB sata II HDD
HP DVD740 IDE dvd-rw
Sound Blaster Audigy LS
Case fans: 1 regular 120mm, 2 LED 120mm, 1 LED 80mm
I don't know what all consumes power from the 12v rail so if I missed something I apologize. If someone would not mind enlightening me to that, I'd appreciate it.
Thanks in advance.
