Quickie Question: Do I need to upgrade my power supply too?

Hey everyone--just a quick one for you: I'm upgrading my gaming rig in the next couple of weeks, and am unsure if I need to upgrade my psu as well. Here's the system:

MoBo:GIGABYTE GA-P55-USB3 LGA 1156 Intel P55 USB 3.0 ATX Intel Motherboard
http://www.newegg.com/Product/Produc...82E16813128425

CPU:Intel Core i5-760 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Desktop Processor BX80605I5760

Video Card:SAPPHIRE 100314SR Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

Additionally, I've got 2 cold cathodes running, 4-120mm and 1-200 mm fans, 2 DVD burners, a Tuniq Tower 120, and 1 usb hub drawing power. My current power supply is the Antec NeoPower 550 550W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply. Bought it three years ago for my last upgrade.

Antec's psu calculator rates that upgrade at 417W, while newegg recommends 587W. Given the difference, thought I'd get some more input.

Another thing I have to keep in mind is that all of my old parts are essentially going into another case for sale, and as of now I have no psu to put in there. So its get a new one and put my current one in there for sale, or get a cheaper one (have to be really cheap not to just spring for a new one, I guess) to put in there and keep this Antec NeoPower. Pretty much at the outer edges of my budget at this point as well, but if you tell me this psu won't hack it or there's no cheaper one that makes the trade-off worth it, guess I'll have to suck it up 🙂 Gracias.
 
It should work fine at stock or non-overvolted speeds, but definitely not one of the better psus at this point.
 
Seriously, you don't need it. The rig in my sig maxes at 230 watts from the wall when gaming (so factor in efficiency and my parts are actually getting a lot less than that from the PSU), which is less than half the capacity of your current PSU and my rig should be more power hungry than yours unless you plan on OCing to the moon. Even still, you should still be WELL under capacity. If money is tight, you are wasting it.
 
Imho, the main reasons to change psu aren't related to wattage upgrade. It's more because the neopower is kind of an old model with worse efficiency and power characteristics. But if it's been working fine without any issue for years, it's likely to continue to work fine.

Plus a 650 will allow future upgrades.

Can't go wrong with XFX or Seasonic
