I need to pick a PSU

[mahin1islam]

I ordered a barebones kit and a good GPU, now i just need to pick a good PSU to work with the GPU.

Barebones kit:

GPU:

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1288240&CatId=3669

so the GPU recommends a 550w PSU. I think i need a bigger one. I plan on SLIing in the future, and also, i want to make sure that there is no risk of it crashing, so i need a good PSU. but also, i want to spend as less money as possible. Which PSU should i get, and what would be the best deal for it?

If you are going to SLI in the future....you NEED AROUND 1000 Watts...from a good brand like Corsair etc... and they aint cheap...

You need a unit with at least two PCIe 6-pin connectors, and a combined 18.25a The card itself uses 219w so you will need something that has enough spare room for all of your other components. For a typical system 250W is more than sufficient for all the other components. The sweet spot of efficiency is 50% capacity of the psu, however under 20% and your efficiency drops off dramatically. You probably don't need anything more than a 750 to run 2 GTX 570's in SLI mode. For only one can anything 500 w or above is probably fine.

Underpowered units are generally much worse to have than over powered units, so W creep usually sets in to recommendations. The card company tacks on 50W more than needed "just to be safe". The calculators tack on another 50W just to be safe, then when people make recommendations they tend to tack on 50-100W just to be safe.

Anyway...

This is a good unit for a good deal right now:

eta: I missed the sli part first pass at this thread. You do probably want something a step up from 500 for SLI. 750 seems to be a good SLI number to hit. Plenty of room to Overclock even with most cards.

If you want to SLI/CF I would recommend a PSU that has 4xPCIe connectors like this Rosewill Capstone 650W with 10% off right now http://www.newegg.com/Product/Product.aspx?Item=N82E16817182071
or this XFX 650W with a $15 rebate http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014

The Capstone unit is a great one. If you are wanting to SLI in the future, that's the way you should go.

The 750 is not on sale atm, but that would give you plenty of room even for some overclocking.

Newegg has a new promo code for Seasonic PSUs; 15% off with code seasonic15.
This Seasonic 750W can be had for the same price after discount.

I don't think you would go wrong with either of these PSUs.

I like the corsair 500w idea for a single GPU, and i found a good 750w a little over my psu budget (i can always save up):

so...what do you guys think? do you think it will do me doo with my current setup?

1000 watts? Are you serious? Come on, Brett. I though you were the one who manage a company that built computers for a living?
It's either you are flaming & I fell for it or you really don't know what you are talking about. But you are right about Corsair being a good brand, though.

To OP:
Better save up & get a 750W corsair for good measure. It can handle SLI or CF Easily with room for overclocking your CPU & GPU. It is a pain to buy a 500W PSU now then decide you want to go SLI or CF down the line & need to buy a PSU again.
