Question: What Graphics card can I use to upgrade my system? with only 220watts on PSU

System:
Acer AX1430-UR12P
SlimLine Tower Dimesions:
Height 10.6"
Width 3.9"
Depth 14.5"
PSU: 220Watts
Windows 7
8.0 GB ram
AMD E-350 processor (1.6ghz Dual Core)
500GB Hard Drive
Current GPU : Radeon HD 6310 (492mhz clocked) really bad...

I was wondering which graphics card I can get without having to change the psu?
And would give good gaming performance with low power consumption?

Ive done some reseach online and the E-350 currently uses less than 18watts itself, not to mention with the whole system only draws 32watts maximum :

So far heres what I am thinking of:

GeForce GT 430:

Radeon HD 6450:

Radeon HD 5450:

but i really dont know what uses how much power.. suggestions?

The Radeon HD 7750 is the fastest graphics card you can get right now that doesn't require an auxiliary power input; it draws all that it needs from a 16-lane PCIe slot. get a 7750

he Radeon HD 6670 would be a better choice then any your looking at bud for gaming on any less would be a joke imho and you'll be very mad.if you buy any those cards you listed over a 7750 or a 6670.

Hello there.

Your bobcat fusion apu's dual core is roughly the equivalent of a 2.2ghz athlon 64
single core processor(that is actually what I am typing on right now). Bobcat cores
are each two way superscalar, meaning each core has 2 floating point units and
2 integer units for a total of 4 each in a dual core. Athlon 64 is three way super-
scalar. Both bobcat and A64 have an integrated memory controller to boost
responsiveness and decrease latency. The effectively four way superscalar bobcat
at 1.6ghz is again about the same as a 2.2ghz a64 single core.

That said, I think an hd7770 would be severely bottlenecked by your processor.
Also, your current apu is about as powerful as you can get on that socket.

The integrated graphics processor in the apu is about the same performance as
HD5450(a little lower, actually). The HD6450 should be an OK upgrade as it is
over twice the performance of the 5450. a normal gt430 might be bottlenecked
somewhat in that system and I think a hd6670 more so. I am sorta thinkin bout
adding a card to my system similar to the gt430 but using an old school pci
connector. The bus and my processor will be major bottlenecks but maybe I will
be able to play some of the games I used to before my last gpu died(rocking a
circa 2002 geforce 2mx at the moment). Since the 6450 is between the level of
older cards like x800xt, x1650xt, hd2600xt, hd3650, and geforces 6800ultra,
7600gt, 7800gs, 7800gt, 7900gs, 8600gt, 8600gts and 9500gt I think that would
work pretty decent for you. Also it has a very low tdp, so hopefully your power
supply wont die or catch on fire with it like it could with a more powerful card.

220w??

Radeon HD 6570. I can't consciously recommend a better graphic card than that.

^ +1 . hd6570 is the only card that's a worthwhile upgrade while being within your power supply limits.

Sorry,meant 7750, not 7770. Here's specs and tdp for all these cards: (amd, then nvidia)

http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics...

5450 at top, scroll down for your 6310 specs, then 6450, 6570, 6670 and 7750.

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graph...

click the down arrow a few times and maybe scoll right to see the tdp for gt430

I think gt430 and hd6570 will have similar performance to one another, and both
will bottleneck on your system. The somewhat higher performing(and higher 66w tdp)
6670 and highest performer suggested 7750(lower 55w tdp) would absolutely be
bottlenecked by your cpu.

I'm still sticking with the 6450 suggestion. Since it is over twice as fast as what you
have, you should notice a difference.

did some google image searching on your pc and found out some things about the case.
Here are some computers with your case on sale at ebay:
http://www.ebay.co.uk/sch/i.html?_nkw=acer+aspire+ax
Here is an article at pcworld about a computer using your case:
http://www.pcworld.com/article/236545/acer_aspire_ax192...
click the pics to see the side, back and inside of the case.
based on that , the case has side intake and top exhaust for graphics cards, and side
intake/rear exhaust for CPUs. Depending on the position of your pcie express graphics
(PEG) slot, you can either go dual slot internal(no back vent) or single slot only. Also,
based on a case width of a little less than 4 inches, it looks like you are limited to a
half height(half as wide) low profile graphics card as well. You will want a card that
includes shorter back plates for just dvi and hdmi(if you need a vga 15 pin d sub
analog connector, you will have to buy a dvi to vga adapter).

How many amps(A) are on the +12v rail of your power supply? Check the label on the
supply after removing the case's side panel if you don't know. The number of amps on
the +12volt rail is one of the most important specs on a power supply since almost
every system component uses it, especially the cpu and gpu.

Hey I actually took your suggestion and i recently bought the Radeon HD 6450 and it is worth the upgrade. Ive notice a Triple increase in FPS and performance

it came with a AfterBurner and Overdrive function also. Do you think it'll be safe to overdrive it as of right now the core speed is at 625mhz and can be overclocked to 850mhz max i believe

If you refer back to that wikipedia page with specs for various radeons, you will see there
are 2 versions of HD6450. One has a core clock of 625mhz and a 18w tdp, while the other
has a 750mhz core clock and a 27w tdp(20% faster, but 50% more power). The faster
model does also have faster ram. You can try and overclock to 750, but your vram may
bottleneck any fps increase that core overclock might afford. Plus, you may run the risk
of pushing that 220w psu over the edge(probably not, but better to be safe). If you are
fairly happy with the performance you have now versus where you were before the
upgrade, I'd say leave your clockspeed alone and enjoy, not risking a potentially
dangerous overload of your psu.

I have the MSI HD6450 18w TDP version with 2GB GDDR3 memory, i was thinking of leavin it alone too because perfomance wise its already good and thanks so much for the help!!
