graphics card for a 500w 18amp on 12v rail

[ysf521]

Could you guys please gimme advice on a GFX card for a 500 watt PSU from cooler master running 18 amps on the 12 v rail

I probably wouldn't get anything higher than a Radeon 7750, that's a pretty low powered unit

Are you sure this isn't a multi rail psu? That's really low even for a crap psu. What's the model number?

a r9 270x will run no problems and a Gforce gtx 760 will run good as well. just make sure it has the right number of PCI-e hookups attatched to it and you are golden.

Ye Sorry abt the incomplete info,its a Cooler master rs 500 pcar A3
Its details are so

+3.3@22A , +5@25A , +12V(1)@18A , +12V(2)@18A , -12V@0.5A , +5Vsb@2.5A

I plan to run the below setup on it

ZOTAC NVIDIA GeForce GTX660 2GB 2 GB DDR5 Graphics Card
Intel 3.4 GHz LGA 1155 Core i5 3570K Processor
Gigabyte GA-Z77MX-D3H Motherboard
Corsair Vengeance DDR3 8 GB (1 x 8 GB) PC RAM (CMZ8GX3M1A1600C10)

But im not sure of the shortfalls and how much it strain the PSU

any alternative suggestion would help

In that case your PSU should be more than sufficient for that setup

Do you have that PSU already? you could have gotten a much better alternative

awesome,
I actually do have the PSU , its been stowed away for 2 yrs or so, its outdated I guess ,that's why the Amps are low in comparison to the ones out now,

how high can I go on the GFX card, without burning out the PSU,? I guess ZOTAC NVIDIA GeForce GTX660 2GB 2 GB DDR5 Graphics Card is good but wanna go a better one from NVidia if possible.

The 660 is fine, I'd assume that a 760 would be too if you're not going to be overclocking, cutting it closer than I'd like but it'd should be fine (fingers crossed though)

I had a similar coolermaster PSU (two 18A 12v rails with a total output of 26A) which powered my E8500 and GTX 260

Check the total output of the +12v rails (in watts) and have a look at this, it's a system under load while running Crysis 3

Being old isn't the issue, it's just not a good quality psu.

The 660 should be fine, but if you ever want any upgrades in the future for a GPU, the PSU has to be upgraded.

i agree , i did some research and it really sucks , i bought it along with the case when i didn't have a set of requirements and the guy probably didn't think i would need anything better coz i gave up on the system it ran coz of issues on the motherboard and lack of support here in india.

Never got around to building this , but thanks for the suggestions
