Hi guys,
For the last 6 months I have been slowly saving and purchasing the components for my new PC in 5 years. I am little rusty on this last piece to decide, I was wondering to get som advise about. My last pice is my Power Supply, I will let you all know my system specs and if anyone could recommend a good power supply to run all with ease I would appreciate it.
AMD Phenom II x6 1090T 3.2 Ghz
ASUS M4A89GTD PRO/USB3
OCZ Reaper DDR3 8GB PC 10666(2x4GB) 16 GB in the Future
Ultra Chill tec CPU Heatsink/Fan Silver edition
XFX HD Radeon 5780 1GB GDDR5 4200mhz
2x Pioneer Dvd rom drives
Western Digital Caviar Black WD1002FAEX 1 TB
Thermaltake Spedo Case 7 fans 4x 120mm fans 2x 200mm fans and 1x 140mm fan
Windows 7 Ulimtate 64bit
Let me know what power would be good for this setup
Thank you,

i'd get the second of those.
it's never a good idea to go cheap on your PSU specially when u got a sweet build like your's is gonna be.

The 650 is fine. It's a better unit underneath, it's a lot quieter, plus it's cheaper. Assuming you meant HD5870, a 550W unit would do fine. If you meant HD5770, then even a 400W unit would suffice.
The only issue with the 650 is it won't be able to run two cards in crossfire should you buy another later. If you want two 5870s at some point, get the 750.

actually for the 4870 that's a 500w minimum powersupply, the cpu is 140w, if u try to go with a 550w expect problems. as for the 400w for a 5770...i'll leave that risky setup for dell. here's my one question to you Melfina, do u want to have to replace the PSU when u upgrade your computer again? personally i'd go around a 850w, it's overkill for the systems today unless you're running dual GPU's (high end obviously) but i'm not one to lay down 100$ everytime i rebuild a system for a new psu alone (i have a 750 running the 5770, so i have enough power to add more when i need them(but even then only enough for 2 of them)) but like i said, i've been building a while, and honestly worst mistake i see people make is going cheap on PSU's sure u might not need that 850w now, but u will, and that extra 20-50$ now will save u 100$ then.
couple of suggestions for future proofed psu's
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139013 (110$ if u use the mail in rebate 140$ else)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139009 (130$ another corsair)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087 (this one is widely accepted as the best 750w PSU available, but at 180$ too much for me but an option if u got the $$$ if not another 750w is:)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006 (i think someone already suggested this one)

No jkl, that's not how PSU requirements work.
The 500W 'minimum' is for a whole system including the HD4870. The maximum draw of an HD4870 is around 150W. The Phenom II X6 CPUs are also 125W chips, not 140 like the Quad core 965.
Why you've quoted a 4870 though is beyond me :S
The HD5870 is a bit more at 188W, the 5770 is a bit less around 110W I think it is.
Suffice to say, with an HD5870 and the Phenom II X6, a 450W PSU would actually do the job with an adapter, even if you were using several hard drives. I just suggested the 550 because it natively comes with two adapters, but it's quite a noisy unit at full load, and since the 650W TX is similarly priced to the 550 VX, and is a Seasonic unit and much quieter, the 650 is probably the better buy. 650W is absolute overkill for this system though, you could run two 5870s off that with power adapters no problems.
You say your 750 is only enough for two 5770s, you could actually run four off it, no trouble at all, you'd still have a little room to spare.
It's fine telling people to be safe, but making them spend more money than they need to is simply unnecessary.
Remember, the maximum rating of components is not how much they use in standard usage. With a 4870X2 (286W), three hard disks (34W), an X38 board (55W), two sticks of high end RAM (14W) and an overclocked Q6600 (c. 130W) - my old PC drew only 390W out of the PSU, 450W at the mains input (and PSUs are measured DC-side, not AC-side). So just by adding the numbers up you might think I'd have needed 530W. It isn't the case. You don't get those sort of numbers outside of a hardcore stress test.

Yes I will be buying a new PSU, I'm looking intop the 750 watt or 850watt.
Thank you for the advise,

Seriously though, I'd suggest just getting a 550. Even that's more than you'll need.

What about this type of PSU, I was also thinking Modular as well.
