Hello,
Is it okay to feed my PC+HD5770 with CM Elite 400W.. As I know, maximum power consumption for HD5770 is 108W based on http://www.amd.com/us/products/desktop/graphics/ati-rad... ... Besides, CM Elite 400W PSU does deliver its labeled wattage but the real problem is the high ripple level if fully loaded... The reason I ask this because I just bought this PSU and planning to upgrade HD5770.. Do you think its okay to push the PSU? My PC specs are
AMD Phenom II X4 B55
4GB DDR3 1333mhz
Asus M4A785TD-M EVO
500GB W.D Blue Caviar
CM Elite 400W

It should be fine, but i tend not to get any PSU's from CM, you are best sticking to the good names like Antec, Silverstone, Corsair and XFX.

^+1 it should be fine but if it crashes you knwo what the culprit is... personally I think coolermaster is crap for psus, even the high end ones, like griff said go with a psu of about 500w from a reliable brand such as antec, corsair, seasonic, silvertone for the 5770

if you go with an antec... avoid the basiq series like the plauge

Cooler Master or not, your power supply should be just fine with a 5770. Those cards are really light on power for the performance they give.

The 500W Basiq received a Golden Award from HardwareSecrets; nothing wrong with that one at all. Someone reviewed the 430W model though (could not find the link), and found it mediocre.
Here's HardwareSecrets' conclusion on the CM Elite 400: http://www.hardwaresecrets.com/article/Cooler-Master-El...
Ripple was high. Since they barely got 420W out of it, that means it was running on the ragged edge, the high ripple indicating the wheels were about to come off it. I would NOT use that PSU, even with a HD5770. Is it really worth the risk?

yeah thats more in line with what I was thinking but... in the end you can get a worthwhile upgrade for maybe 50-60 bucks

yea, i researched the 500 and it seems to be different... btu i had tow machines die to basiq units blowing , i figured the first was a fluke, so i rma'd it, they gave me a new one ... which blew about 5 months later, it was the 350 watt though, thought i was goign with a good brand... nto buying antec again

*add*

and in case peopel think i was overloading it, the system was using onboard video, just a small machine in the living room for browsing the web, on a teble good ventilation with a keyboard and mouse for facebook/myspace/youtube on the tv
