Hello, Is a 500 Watt PSU powerful enough to run a Packbard Bell, Quad 2 Core 6gb DDR2 Ram, 64 bit Windows 7 when I add a ATI Radeon 5770/5570?

The PSU only has 1 6-pin so I wondering if the that card only needs 1 of them not 2...

pretty sure most of the 5570's and 5770's use a single so you should be ok...

do you know how many you gpu requires? if just one then no prob

5770's MUCH better than a 5570. Even a GTS 250 would be better than a 5570 (not to be confused with a 5750). Also, your RAM might run faster if you use two matching sticks in the motherboard slots of the same color.

Both the ATI Radeon HD 5770 (108 Watts or 9 Amps from +12V rail) and 5570 (39 Watts or 3.25 Amps from +12V rail) would never consume more than 150 Watts so they would never need more than one 6-pin PCI Express supplementary power connector. The 5570 doesn't even have a 6-pin PCI Express supplementary power connector since it consumes so little power.

What is the make and model of power supply unit? Total wattage is not the primary specification you should be looking at. The critical value is the combined maximum DC current capacity of the +12 Volt rail(s).

Good brand name power supplies like CORSAIR, Seasonic, Antec, XFX with a capacity of at least 450 Watts or 500 Watts will be sufficient as long as the Packard Bell's computer case is not a slim form factor case.

If it's a slim case, wouldn't he need a low-profile video card? :D

The system is a large case. I have a OCZ Stealth X Stream PSU.

Sorry for double post...

I can screenshot the case of the PC. I'm also replacing the current graphics card which is a GT 320. The thing was able to run FFXIV at a low setting.

In most cases yes. I have seen some slim line cases where they use a riser card that flips the card so that it is parallel to the motherboard so that full height cards can be used.

Your OCZ StealthXStream 500 W will have no problem providing power for that card and the rest of your system.
