Is 430w enough?

I'm looking to upgrade my Radeon 7770 to a new R9 280x, but I only have a 430w power supply.


Mobo: BIOSTAR A960D+ AM3+ AMD 760G Micro ATX AMD Motherboard

Graphics Card:  SAPPHIRE 100358L Radeon HD 7770 GHz Edition 1GB 128-bit GDDR5 PCI Express 3.0 x16 CrossFireX Support Video Card

PSU: CORSAIR Builder Series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

CPU:  AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor HDZ965FBGMBOX

RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-

HDD:  Western Digital WD Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive - OEM

Can i still keep the PSU I have and use a 280x then upgrade it a little later to like a 650w?

More than.

Probably not. I would settle with at least 750

You will need a better power supply. You can get the XFX 550W bronze for cheap, probably the minimum I power delivery I would recommend with any certainty. Plenty of amps. Considerably better than the CX series.


750W for a single GPU? You can't even deliver more than 300W with dual 8 pin PCIe connectors on standard ATX amperage!



A 550w 80+ psu will be fine grab 600w if you are paranoid and run a 100 extra hdd's

You are probably right, but you also have the get-more-than-you-need principle for PSUs. If money is an issue, then 550-600+ will probably be fine. 420 probably not.

So 430 wont work?  I'm new to computers and know no technical terms.

I would try with the 430w and see where it takes you.  If it doesn't work, order a new PSU like the XFX 550w people are recommending.

it won't work, i have a similar setup and it wasn't enough for mine.

Could it harm my system if i try?

What's a good 600w or 650w modular psu?


I would say it is plenty, might limit overclocking though

Plenty enough. Yesterday I put my 7950 in my mates PC with a Corsair 430W. It ran fine, I didn't play any games mind you.

no, it'll harm your wallet though.
