PSU Guidance

post #1 of 3
Thread Starter 
Good Evening.

I've recently added some components to my rig (in my signature), and went to overclock my CPU, but decided I needed a better PSU to meet the requirements for my OC. What I need help with now is deciding how much power/what PSU I need. I hope to get an overclock up to about 3.5-4.0 Ghz, and I'll have Crossfire going with an ATI 5770 and a 6770. I also hope to add an SSD in the future.

Current configuration:

Intel Core i5-750 @ 2.67 Ghz (hoping to OC this as mentioned above), cooled with a CoolerMaster Hyper 212+
Asus P7P55D-E Pro
4 GB of Corsair XMS DDR3 RAM @ 1333 Mhz
ATI HD Radeon 5770 + 6770 in Crossfire
3 120mm case fans
1 1TB 7200 RPM HDD
1 HP CD/DVD drive
*Future* 1 256 GB SSD
5-8 USB devices (just in case)

Current PSU: Corsair 550VX @ 550 watts


New PSU Requirements:

-Relatively cheap, I'd prefer if I could stay below or near $100
-Room to grow (I'm adding a few components in the future, mentioned above)
-Good reputation/brand (I don't want a generally-bad PSU, I'd rather just pay more)
-Quietness/efficiency is nice

Any insight is appreciated!

your current 550w would run that rig fine.


Since you're adding in the future a 650w-700w would be plenty

I would say 650W would be plenty, pick one up from a brand like Corsair, Seasonic, Thermaltake, or even Antec.

although I think 550w would run it just fine, my two cents.
