I have recently decided to upgrade my computer with a Ati Radeon 4770. This would mean I would need new power supply unit. Within the last 2 days I have decided that I wanted to upgrade to Ati Radeon 4770 Crossfire which would mean I need even more powerful PSU.
:::What I am working with:::
-Dell Inspiron 530
-Intel Core2 processor Q8200 (2.33Ghz) w/Quad Core Technology and 4MB cache
-4GB DDR2 SDRAM at 800MHz
-320GB Serial ATA 2 Hard Drive (7200RPM)
-Windows XP (I have a Vista sp1 disk too)
Everything else is just standard.
:::Video Card:::
ATi Radeon HD 4770 (x2)
:::Video Card Specs:::
-PCI Express® 2.0 x16 bus interface
-128-bit GDDR5 memory interface
-Microsoft® DirectX® 10.1 support
:::Video Card Requirements:::
-PCI-E based PC with x16 Lane Graphics Slot
-450w with a 75W 6-pin PCI Express Power Connectors
-550 Watt and two 6-pin connectors for ATI CrossFireX technology in dual mode (((THIS IS WHAT I NEED FOR CROSSFIRE)))
So I have two questions...
I only have enough money for one 4770 at the moment. Can I buy a PSU that can run both 4770's for Crossfire and then only run one 4770 until I have enough money to buy the second, or will having a PSU with too much power screw up my computer?
...And what is a recommended PSU? I have been looking around but cant find one that stands out...
My price range for a PSU is $35-$65 but if there's one that is really worth it Ill spend around $80.
As you can see, this is quite the situation and needs the advice of some computer experts to solve this one.
