PSU Upgrade

post #1 of 9
Thread Starter 
Right now I have a 300W Delta Techologies power supply unit. It came with this Gateway PC I got back in 2007. It has been sufficient for my needs so far, but now I am planning to upgrade my video card.
Kill-a-Watt reports that the total power consumption for my PC, my monitor, and my speakers is approximately 260W, so I know that even 300W PSU is overkill for my current setup (my PC probably only draws ~150W), however, my graphics card is a measly HD 4550 (~20-40W)

Now I want to upgrade to something more powerful. (pun intended)
I am planning to get an HD 6950 graphics card. I know that this card draws around 300W on load and around 160W on idle. This card requires two PCI-E power connectors. I am not planning to crossfire, because my motherboard has only one PCI-E slot.
Everything else in my computer will remain the same, including CPU, GPU, RAM. I might upgrade HDD to a 1TB Samsung Spinpoint F3 and a case with additional fans later on.
I would like a power supply that is reliable, has a good warranty, and of course, is reasonably priced. I don't need any overkill, as I will not be adding anything extraordinary to my computer beyond this HD 6950 graphics card, and I am definitely not going to overclock it because I need it to survive for at least the next 4 to 6 years, during which time I will be attending university.

In short, what is a good, reliable power supply of at least 500W and two PCI-E connectors??

Any good suggestions are greatly appreciated!

Look into a quality brand like Corsair or XFX, any of their 550w+PSU can power that system. But I do recommend leaving headroom for future hardware upgrade and possibly overclock; This is overclock.net So perhaps a quality 650w+ such as the TX650w

I personally love Seasonic, Silverstone, PC P&C, Corsair, and (when in a pinch) Cooler Master. Grab a Seasonic X-Series 650W and you'll be good to go.

wth is up with all you guys suggesting 650w supplies? OP clearly stated he doesn't need it.

Check out some of corsairs cx series, they have a nice 430w. Not entirely sure if that has 2 pcie cables though.

antec's 550w is one of the best low wattage modular supplies.

I am sorry that I didn't notice the FAQ list first when I came in.

I like this one. It's an Antec NEO ECO 620W; it has two PCI-E connectors, and it is a good deal in my opinion ($70). I think it provides enough power and headroom for my needs.

Thanks for the help, people.

I think I could get away with 500W, but not 430W. My current system draws around 150W... adding a 300W video card brings me exactly to 430W... I would get absolutely zero headroom on a 430W PSU and the computer would shut off during heavy gaming.

Uhh. no.

Here's the actual power draw of a 6950. http://www.anandtech.com/bench/Product/293

320w in furmark for the entire system. still 110 watts of free space and you'll never stress it as bad as that anyways.

I'm still voting for that modular antec 550.

BTW of course the manufacturers want you to buy a 550 or greater, they make that statement assuming you have a garbage PSU that peaks at like 350w.

Add some overclock and maybe 2nd card later and you will go over.
PSU is most efficient at 50% use and also usually more silent when not running close to 100%.
