I have a gateway dx4300
300w power supply
Intergrated graphics
Running windows 8

The gateway website lists my specs at this address: http://support.gatew...DX4300sp2.shtml

I wnt to play MMORPG games like wow or star wars the old republic

Thank you

Hi and welcome to the forums. The first thing you need to do to give yourself some flexibility is to upgrade the Power Supply. A 300w PSU will not do it for any decent Graphics cards.I don't know what you are willing to budget for this. I'm sure you'll get other suggestions and good ones, but this a decent Power Supply: http://www.newegg.co...N82E16817256061


This should be a good card and it comes with Assassin's Creed III - http://www.newegg.co...N82E16814130827

As I said, you'll probably get other input as well. At the moment, I am doing this from a Hospital Room with what ever internet connection they have around here.

I'll just note that the 650ti only has a 64W TDP, so you could easily get away with a Corsair CX430 ($46, but only $26 after rebate).

What about a AMD Radeon HD 7750?

[coastie65]

Should be fine. I think there may be a 7770, if so, it should be a tad better.

64W TDP my @#%!!!!

110W TDP

TDP is a misnomer. I prefer nVidia's MGP designation. But in your usage it means the same thing.

A 7750 will work provided it provides 4.6A on the +12V rail for the card with enough left for the system. (I mean how good of a PSU came with the system?) Figure if it doesn't exceed 25% would be a good margin of safety.

A 7770 at 6.7A on a 300W PSU (assuming at least a ATX12V rev. 2.01 or greater) is really pushing things. I would not try OCing it.

Oh whoops, it looks like that's the non-Ti version then.

A quality 300 watt PSU will easily handle a 7A load... something to do with basic math. 300W/12 = 25A. Assuming a worst case scenario of only 20A actually being available, A worst case CPU load of 10A, plus the 3A in supporting equipment, and we get a total of 20A. In other words, even at the WORST CASE scenario, a 300 watt PSU will still work. Yes, it will be tight, but it will work.

Where to begin? 1) A quality PSU...it came with the Gateway, nuf said. It may be a good PSU it may suck, but quality no.

2) Provided your hypothetical PSU only has a +12V rail OK 300W/12. Most divide it up between a 3.3, 5 and 12V rail(s). Real world, if we are lucky that PSU has 18A on the 12V rail available and not split up, or in fact a lower amperage available. If we are really lucky it has a real 18A at 50C and not some kinda sorta room temp 18A available.

4.5A would represent 25% of the available draw on an assumed 18A capacity of the +12V rail. Pretty reasonable. Much more than that and you start to threaten to overload the PSU's capacity with its other system demands on that rail.

3) 6.25A is the max available through the x16 slot on its 12V lines. If a GPU card may need more it must provide aux. power inputs which the 7770 does. Around 4.5A is a safer cushion.

4) I am pretty certain I indicated in my "basic math" the 7750 was safe while the 7770 is pushing things---because we don't know how good the PSU is, but I certainly doubt it is very good. The 7770 is right at the threshold, maxed out and especially if OC'd might cause a PSU surge. Worse if that PSU is old enough and diminished in its full capacity, or predates the 2.01 revision where power was shifted from predominantly the 3.3V and 5V rails to the +12V rail the the amperage on the +12V rail could be as low as 12A. edit: Since it came with Vista OS it seems unlikely that the revision is less than 2.01. While a rear view image at least confirms an ATX form factor PSU, unfortunately a list of possible model numbers to look up is not provided so the OP will have to open the case and look on the PSU label for themselves.

It is the non-Ti version. I should have seen that in my chart and for that kind of power drop in a GPU makes me wonder what rebadged model it is?

Most likely it is a Lite On PSU that came OEM in the Gateway. I know it was in my FX6800- 01e.

Start with the facts. Which you did not.

Actually no. Again, start with facts. FACT: Current power supplies convert 100% of the power to 12V, and then use regulators to supply the extra leads. I also assumed 5A of the 25 total was unavailable, you really think that a power supply on a current design would use more than 20% of its power to insignificant rails? EDIT: Current designs are those within the last 7 years give or take.

That number changes based on exact specs. Some still use 5.5A spec. In any event, where the power is drawn is actually of little value when dealing with a machine of this nature. The fact is, that power supply is bound to be a single rail design, with all the power being delivered as needed to any location.

Wow... no, your "basic math" is based on assumptions not in play, or not based on fact. The questions here are not about an overclocked system. They are about weather or not a 300watt power supply can take on a 7750 or 7770. That answer remains YES.
