Queries changing the cabinet and psu of a dell inspiron580s

[ssj21]

hello guys i'm new here.. i had bought my dell inspiron 580s with corei3, ram-4gb ddr3 and a nvidia geforce 8400gs gpu a year ago....
i want to get a better gddr3 or gddr5 gpu for my machine to run new games at a medium or high quality. i see that the low power psu on my machine won't support new gpu and the cooling system is very poor as well..again i see my cabinet is too small for a better psu.... i'm a bit afraid experimenting with this machine
can u suggest any better psu and cabinet for my machine with a low price?
any help will be appreciated

The Dell Inspiron 580s has a µATX (a.k.a. mATX, microATX, uATX) form factor motherboard. Are you looking for a full size ATX case or a mid-tower or mini-tower ATX case?

Which discrete graphics card make and model are you planning to use? This information is needed to determine the correct power supply requirements for the system.

What is your budget for the case and power supply unit?

The Dell Inspiron 580s' case will limit you to low profile graphics cards so it's really not worth sticking with this case. Also trying to find a good TFX power supply upgrade for that case isn't worth the trouble either.

For a system using a single Radeon HD 6770 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 25 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

You didn't specify the Corsair power supply's model number but there are currently two 500 Watt models in their lineup:

The Corsair Builder Series CX500 V2 (CMPSU-500CXV2), with its combined +12 Volt continuous current rating of 34 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 6770.

The Corsair Gaming Series GS500 (CMPSU-500GS), with its combined +12 Volt continuous current rating of 39 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 6770.

What is making you think that the power supply will burn your motherboard?

and this cabinet Yes it will work, but it doesn't have good ventilation.

One 80mm fan is not that good. That cabinet can handle two 80mm case fans so you should add another one or get a better ventilated cabinet.

and will the gpu powercolor ati hd 6770 1gb gddr5 give a decent fps for new games at high setting ?? What do you call decent FPS? Which new games? here's flipkart's link

You should be able to get 30 to 40 FPS in BF3 at 1366x768.
