Budget card for 520W PSU?

I would guess the 750ti is about the best card to run on questionable power supplies.

The specs list the power supply as having about 400 watts(they say 420, but lets be honest here) with a peak of 520.

I do not think you will get a 750ti(and much slower may not give you the performance you want) in the 100 dollar range unfortunately.

Just ensure whatever you get does not need more than 1 x 6 pin pci-e connector. The power supply has an 8 pin, but I am not sure of the Dynex quality since they just get whatever they can and slap a name on it(I had to get the manual to even see the actual specs.).

Very few companies still sell power supplies on PEAK and tend to sell on continuous power instead.

Dynex is classified here as tier 5, very bad, almost a fire hazard.

"Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system."
 


How will these two cards work?

I have two 6 pin connectors if they need extra power to run.
 
Hi,

Fallout 4 requirements as follows;

Minimum
NVIDIA GTX 550 Ti 2GB/AMD Radeon HD 7870 2GB or equivalent.

Recommended;
NVIDIA GTX 780 3GB/AMD Radeon R9 290X 4GB or equivalent.

Tom's Hardware also does a handy gpu hierachy chart that may well be useful
 
Even if it does work, both those cards and scraping the bottom of the games requirements. The AMD card may take MORE power than the 750 ti and be harder on the power supply.

I have to point out I have NO experience with Dynex power supplies(I am sure for a basic office system it may work fine). I would almost go as far as to de-rate it to at least 300-350 watts just for selling it as a 520 watt unit when it would DIE under such a load.

You are really between a rock and a hard place.
 


I don't really want to put the computer under too much of a load, I know the power supply isn't the best quality. But, right now money is tight and I'm trying to get the best bang for my buck. I can't afford a new computer at this time. Either way, I'm gambling $100.
 


I really don't trust it either, but I have had no issues with it thus far, except for the constant low humming sound. I am planning on replacing it when I have the money.
 


Both are at the bottom of the barrel. Logysis and Diablotek are the worst.
