black screen with hd5750 on 1860x1050

soulspirit · 10-22-2009, 12:12 PM

hi,

i just bought a new powercolor ATI radeon HD5750. in reinstalled windows 7. installed the newest drivers including chipset and monitor. however, when i turn my screen resolution to 1680x1050 i get a black screen or some heavy flickering. 1440x900 is possible but is not acceptable on my 22''

my system is a:
p5b mainboard
intel e6400
2gb DDR2
BeQuiet 450
ati radeon 5750
monitor: HP w2207

thx for any suggestions

Well number one take out the card and do not put it back in until you have a decent power supply to run it. Be quiet is a bad brand in power supplies and 450w is not enough for that card. You need a power supply upward of 650watts at least.

The BeQuiet 450W is not only insufficient to run your system, but garbage as well. Horrible voltage stability (+12V rail runs at 12.45V when under load, which is enough to damage your system), and a bad power distribution.

For a 5750 you'll want a Corsair TX650W or similar PSU.

hmm im wondering.. the 5750 uses not even 150W and imho there is not a lot additional hardware in my pc consuming that much. the minimum requirements of the ATI are 450W (and thats for a very low end power supply) and imho a bequiet e5 is not the worst powersupply out there.. after all its a low end graphic card and no SLI..

however the corsair looks quiet decent for that pricing

sry for my bad english ;)

Read this:
Power Supply Information and Selection

You might get by with a quality 550W unit (Corsair VX550W, SeaSonic S12D 550W, etc.), but we recommend the 650W. The manufacturer will always low-ball the power requirements. And though the BeQuiet is not the worst power supply ever (that award goes to the Huntkey V-Power series and IPower 650), it is definitely not a good power supply.
