The power requirements are low roughly 100+W on load and about 20W when idling.
You should be fine.

Whoa, glad this emergency got handle so quickly, was afraid someone might die!

But yeah, they are right, from HIS's website:

Quote:
450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireXTM technology in dual mode)

Yeah, that supply has the 6 pin connection that will work on more every graphics card (it has two of these, so you can power 2 cards or a 1 newer nvidia card).

The cooler master GX series is crap, if you havent already bought it, dont. Get a good unit like an Antec EA500D, it will handle the 5770 with no problem, but stay away from the cooler master GX line up, they have significant ripple issues on the 650W and 750W unit, the 450W unit barely stays in spec, they are poor quality units but priced at the same level as much better units.

how can u say that hunter ???

HardOCP gave the GX 650W unit a FAIL
http://www.hardocp.com/article/2010/11/22/cooler_master...

Jonnyguru gave the GX 750 a 6 for performance on its first run through, and a 3 on its second because it failed to stay in spec
http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

Hardware Secrets said this about the GX 750 "it is only safe to run this new Cooler Master unit up to 450 W."
http://www.hardwaresecrets.com/article/Cooler-Master-GX...


Now, if the 750W unit can only stay in spec up until 450W, what makes you think the 550W is going to come anywhere near there? They used cheapo suscon capacitors and have a design that cannot output its rated wattage cleanly, how it made it through 80+ certification when it cannot stay inside the rather liberal ATX spec i dont know.

Buy coolermaster silent pro series psu.
February 16, 2011 9:32:10 AM

February 16, 2011 9:34:10 AM

and what about CORSAIR 550 WATTS (CMPSU-550VX) NON-MODULAR (12V / 41A) is it good

February 16, 2011 9:42:50 AM

Who told you its requirement is 40amps?
February 16, 2011 10:03:51 AM

from different websites !!!!! and whats your opinion
February 16, 2011 11:30:25 AM

February 16, 2011 12:11:06 PM

Corsair is very good - I would definitely recommend them.

Absolutely Pallimud. God what was the emergency there? :lol:

hey man whats ur idea about cooler master GX-550w , i think it will be good for ati 5770 !!!!
March 2, 2011 3:29:23 PM

It should work fine, it's just not a particularly good power supply for the money, but you will likely never notice because you won't be pushing anywhere near it's advertised limits with a 5770.

The Cooler master GX series is bad, they cannot stay in spec providing more than about half their rated output wattage, see the links i had posted up above. If you get it and run it over about half power you risk your system as the ripple on the minor rail exceeds spec and ripple is quite dangerous to sensitive components. I really advise against getting a unit from the GX series.

See if you cannot find an Antec Neo 520W, Seasonic S12II 520W, Corsair 500CX or 550VX.

^ what hunter315 said.

If you really want a Cooler Master then only go with their SilentPro models, those are solid.

GTA IV is not fully compatible with Win 7, read here http://forums.techarena.in/video-games/1108399.htm

Also, WTH are you running a 5770 with a i3 on a 15" monitor? Get a 17" at least. It's like running a speedboat inside a kiddie pool.
