Hi,
I am building my new photo editing/gaming PC. I have 2x Sapphire HD7970 GHz Ed Vapor-x 3GB graphics cards in xfire and for PSU I've bought Corsair GS800. So my question is will this 800W PSU be sufficient to power my system effortlessly without any issues? The AMD official site states that a minimum of 850W PSU is recommended. Please suggest if I should use this PSU or try to exchange it for a better one with higher wattage?
I am also concerned because my CPU/mobo combo are also power hungry. I have a 3930K processor and Asus P9X79 Deluxe motherboard. Let me give you my whole system configuration, so that it is easier for you guys to recommend the best PSU for this build.
CPU: Intel i7 3930k
Cooler: Corsair H100i
Motherbboard: Asus P9X79 Deluxe
RAM: 4x 8GB (total 32 GB) GSkill Ripjaws Z 1600
SSD: 120 GB Kingston HyperX 3K as boot drive
HDD: WD Caviar Green 2TB x2 (Total 4TB)
ODD: LG Blu-ray writer
Graphics Card: 2X Sapphire Radeon HD7970 GHz Edition 3GB Vapor-X in xfire
Sound Card: ASUS Xonar Essence-ST
Monitor: Dell Ultrasharp U2713HM 27" IPS monitor 2560x1440
PSU: Corsair GS800 (This is my biggest concern????????)
Cabinet: Cooler Master COSMOS II
KB: Corsair K90
Mouse: Corsair M90
Speaker: Logitech Z906 5.1
So, please help me out here with the PSU I've chosen here guys. I am worried with that part. Please let me know if you need any other information to make the best decision. And please reply soon as I don't want to delay if I've to exchange my PSU.
N.B. I've found this on Guru3d which raises my concerns even more. It says -
"Here is Guru3D's power supply recommendation:
Radeon HD 7970 - On your average system the card requires you to have a 550 Watt power supply unit.
Radeon HD 7970 Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.
If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina."
So should I not keep a reasonable buffer amount of power available at my disposal ?
Thanks,
Susmit
