if i am going to run a Dell optiplex 755 with 4 2.5 inch 500gb hard drives and 8GB of RAM as an FTP server (this device will run 24/7) what power supply would you suggest as a replacement?

I would suggest at least a 750watt power supply with your system hooked up to an uninterruptible power supply with battery backup and surge protection to ensure your system runs and stays running 24/7. Hope this helps, good luck with your server.

Considering it's TDP is only 120w, most likely. It depends on your system but 750w should be able to handle that without problem.

Make sure your power supply is big enough I got a corsair 750. Power supply from best buy...worth it..and that they supplied you with a couple a different adapters for the SATA cable...2 slots on power supply.... One for disk drive and hard drive and one for Motherboard....so make sure they gave you the right adapters and that you are pushing enough power...at least 600-650 W

Since I don't think this computer's PSU has extra power connections, unless you plan to replace it right away, your best bet would probably be a GTX 750ti. They're right around $150 and most of them don't need extra power connectors.

I agree with GEEZERBUTLER.. who could recommend a powerful + compatible + cheap power supply for this computer?/ thanks

Assuming you have the rest of the computer at similar quality I would look at a 750 to 800 watt supply

I placed the information you gave me in a power supply calculator. I didn't have all the info on your pc so I guessed at some things, such as 2 dvd drive instead of 1, and 2 hard drives instead of 1. The answer I got was a recommended 345 watt power supply. In that case, this power supply here will work great! But I encourage you to do your own power calculations because you have more info about your pc than I do. This is the online calculator I used--&gt; http://www.thermaltake.outervision.com/ the CPU Socket for your pc is--&gt; Socket LGA 1155. Hope I have been able to help you.

280w is more than double what you would actually need to run this thing. It only draws around 30w. The most the PCIE slot can provide is 75w, so you're fine.

It sounds like you are trying to build a miner, or a HTPC. If it is a miner, it should be more than enough power. I've seen specs of mining builds with as little as 250W PSUs. However, if you are building a media server, you might want to push up the wattage to at least 550, just to be safe on the power output. On the outside, if this is a gaming machine, you might be on the low side of adequate. But, it would work. This PSU was out-of-the-box compatible with a 3rd Gen Ivy Bridge Intel processor which, at the time of my build, was what was available for my price range. So, it may work well with a Haswell or later, but I am unable to guarantee it. Hope that helps!

the card alone at TDP will use close to 250 watts... so unless you have an atom processor and no HDDs... more watts the better ;). Plus most psus are less then efficient, My guess is that 350 watts is more like 300

David, you should see in your mother board dell optiplex, and check the model

A 500 watt system is the lowest recommended .I have an 800 watt power supply, because I'm running a lot of extras. It does require a 12v PCIE supplementary power connector as well.

I'm not sure what the minimum power supply is , but i put it in a 12 year old Dell 4400 that can't have a very powerful power supply if that helps.

You can put a retail PSU in it rather than having to buy the Dell replacement. Mine has the 305W, but you can put in anything bigger, especially if you want to add a video card or plug in several USB powered devices.

I installed this on my grandson's computer with 350watt power supply. Only one hard drive and one dvd/cd drive. As long as you don't have a lot of power consuming additions you should be ok!

These types of ATX form factor power supplies are pretty much standard. As long as it has the plugs you need for the motherboard and everything else that it needs (ie hard drive etc etc), it's a better thing than the Bestec you mention. The supply you're referring to in your question is a mere 250 Watt supply. There's no reason to run a computer on so little. This 400 Watt supply, as long as you're not doing anything crazy with it, will do what you need of it.

Not sure if this helps but I am using it on a Dell Optiplex 780 with a 235w power supply with no problems.
