I have bought a GTS 450 1GB DDR5 gfx card. I haven't attached the card to my system. what would be the rating of PSU that I need to fix? I have a 450W PSU supplying power to my rig now.
And I have a C2D 2.0Ghz processor and a 2GB DDR2 ram which I might upgrade in the very near future. I would like to know what games could give me 40-50 fraps(medium settings/1366x768) in the current config i.e.
C2D 2.0Ghz
GTS 450 GB DDR5
2GB DDR2
Specifically
Actually I need Batman Arkham City, MOHW, Battlefield, Max Payne 3 to run smooth. :|

You could have bought the HD 7750 instead.
Anyways, for GTS-450 a good 400W PSU will do. Get Corsair VS-450 for 2.2k.

It may, it may not. Nothing can be said about el cheapo PSUs. Better get a CX430V2 @2.7k

OP - that PSu is good for ~65W ( gfx card without the need of pci-e power adapter ) TDP gfx cards but the GTS 450 has ~105W TDP - so you better opt for a better PSU.

thanks!! :thumbs:

I might go for a processor and ram upgrade.
Processor would be a core i3 2120
and 4GB DDR3 RAM
So suggest me a good budget PSU

Corsair CX-430v2 for 2.5k and CX-500v2 for 3.1k are good VFM options.

Your 450 W psu will do the job, but there local psu's dont supply constant or clean power and are also not very efficient at the same time. When they go bad, they tend to damage the hardware. Read the power supply blacklist thread.
I would suggest you buy a buy a good, reputed psu such as corsair cx500.

Seasonic S12II 430 Watts PSU

IDK about them, but why not buy something that we all know works and works great? get either CX430v2 (Rs.2700) or CX500v2 (Rs.3600).

You might face problems in RMA with Seasonic.
So, better to go for Corsair here.

Corsair is good but can u give me some other alternatives? It was very funny to hear from my dealer that he didn't know about Corsair!! :D :D
Well he might not be dealing with that brand. He sells PSUs of Coolermaster.
Any suggestions? If they cost more than CX430V2 then I'm not going for it anyway.
And how is the platinum series of Zebronics?
I know this el-cheapo stuff can't be trusted but still?

Neither do dealers in my place know about Corsair. Only 2-3 are aware of it.

TO get corsair products contact Aditya Infotech. They are distributors of Sapphire, FSP, Corsair, Zotac and many more.
Check your nearest dealer here and contact 'em. Aditya Infotech Ltd. HOME Page

What is the budget for the PSU?
Also there is a better alternative available from Seasonic against CX 430 V2, Seasonic SS400BT @ 2.64K. Link: *www.flipkart.com/seasonic-ss400bt-...CCMS&ref=3841a842-fd30-452f-b2ea-0d87f1c1530e

Don't go by the total power. In 12V rail, which is the most important part for running higher end Graphics cards, Seasonic model provides 30A current whereas CX 430 V2 is limited to 28A. Also SS400BT is 85% efficient compared to the 80+ certification of Corsair model. Tirupati is the sole distributer of Seasonic products. Check if they are available at your locality.

max 3k

Well if the graphics card gets insufficient power supply, then what would happen?

if the psu is of good quality, it will shut down.
if it is an el cheapo psu, it might do one of the following :
1. blow some capacitors
2. short circuit
3. pull too much voltage from the mains and fry your hardware.

pull too much voltage?? how can it pull more than 230VAC?? :D

but yeah.. point is get a good PSU.

think of the PSU as your heart. if its all blocked up and $hit, it cant supply all the blood[current, voltage] that the body needs, and organs[components] will fail. ;)

It is just a minor unnoticed typo...

Technically beyond a certain current the semiconductor rectifiers in PSU breakdown & allow a larger amount of current this leads excessive heating of psu itself & also for components attached to it.... hence helping you to fry out your GFX,Proccy,MobO etc.. :-D
