Dell GPU upgrade possible? ATI 3650 -> 5770

Hey all,

I have a Dell Studio 540 tower bought a while back and want to upgrade the graphics card so I can play some modern games at a decent resolution (1650x1050) with playable framerates... the 3650 just doesn't cut it. :kaola: 

I'm thinking of going for the 5770, although I'll have to upgrade the PSU too as I've got the standard 350W currently installed. The system requirements for the 5770 states a 450 Watt or greater power supply with one 75W 6-pin PCI Express power connector is recommended so I've seen two that seem to be worth buying. I don't want to spend a whole lot on these upgrades since I'm building a new gaming PC from scratch.

The specs of my Dell:

Mainboard : Dell 0M017G
Chipset : Intel G43/G45
Processor : Intel Core 2 Duo E8400 @ 3000 MHz
Physical Memory : 3072 MB (3 x 1024 DDR2-SDRAM )
Video Card : ATI Radeon HD 3600 Series

Parts I'm looking to upgrade to:

GPU:

HIS HD 5770 1GB GDDR5 DVI HDMI Display Port Out PCI-E Graphics Card

PSU:

Be Quiet 530W Pure Power PSU - 120mm Fan Dual 12V Rails 5x SATA 2x PCI-E
OR
OCZ Stealth XStream 600W PSU - SLI Ready ATX2.2 12cm Fan

- Will these components be fully compatible with my current specs (seeing as it's a prebuilt Dell machine) and boost gaming performance?

- Is the 530W PSU enough or would it be safer to go with 600W?

- Would it be wise to intall another gig of RAM to increase total memory to 4GB and increase performance?

Thanks for any help!

The 530 should work but id go with OCZ just to be safe, the video card should have no problems working on the dell but if it is a BTX model Id be unsure about the PS

your current PSU will power the 5770. it hardly draws any power and the 350w is fairly solid, it offers 350w continuous power but peaks above that.

if you really want to upgrade the PSU, i suggest the Corsair 400w. Its labeled as a 400w unit but its actually a 500w making it a fantastic bargain.

makes sure the HSF on the 5770 has plenty of clearance in your case.

a BTX Dell would have the video card go in fan up rather then the fan down in ATX. The PSU itself does not change, you can use a BTX PSU in an ATX case and vice versa. The only difference is the DELL BTX PSU lacks an "on/off" switch in the back.

You learn something new everyday, thanks. Also is the 400 watt corsair really a 500 watt? Cause my brother bought a 400 watt last November.

power supplies are not independently inspected so the manufacturer can place what ever watt label they want on the package...and often do. that's why you always check reviews on a PSU before you buy it. hardware secrets and johnnyguru do the best job of PSU reviews.

Measured maximum power: 483.9 W at 49.0º C.

they have the corsair 450w at around 575w max (i believe)

Thanks for the prompt replies!

Is this the Corsair 400w? Corsair 400W CX PSU - 12cm Fan 80Plus Certified Efficiency 6x SATA 1x PCI-E

Would adequate space below the installed card mean there is enough clearance space? I believe the length of the card will fit the Studio case...


correct, that fan takes up an entire second slot
