Is this PSU a good choice for my build?

Last response: in Components

Here's what I've got laid out for the PC components. The old PSU just stopped functioning last night (supplies power to light LEDs on mobo but not enough to boot, fans in case won't spin more than 3 to 5 degrees when power button pressed.) and it's still under warranty. Although, I'm not sure if the PC build was what caused the PSU to give out as it is a bit of an older designed model. I'm basically trying to determine if I warranty the PSU and get the replacement if it's still a proper PSU for the build I have or if I should upgrade.

PSU: CORSAIR HX Series CMPSU-620HX 620W (Old one that died, and is under warranty.)

Case: Corsair 500R Stock Fans
Motherboard:Asus P8Z68-V Pro
CPU: Intel Core i5-2500K
Heatsink: Corsair A70
GPU: MSI GTX 560 Ti HAWK
RAM: G.SKILL Sniper Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)
HDD: Seagate Barracuda ST3320820AS (Can't find product page anymore)
SSD: OCZ Agility 3 AGT3-25SAT3-120G 2.5" 120GB SATA III
Ext HDD: 1TB WD 10EADS USB
DVD: H&L GSA-H60L 16x DVD±RW DL SATA Drive w/LightScribe

Doubt that, but it's possible
Older design that should never have been discontinued, mine's over 6 years old and been put thru the wringer, one of the mods uses a 6+ yr. old unit to power a system similar to your's, with a pair of 560's

You will probably get an HX650 in return for your HX620

I originally purchased the 560 with the intent on a future SLI setup, I assume based on your point about one of the mods this PSU will be sufficient to run a 2nd 560 as well?

hmm, http://www.guru3d.com/articles_pages/geforce_gtx_560_ti...

says even with a overclocked system 460 watts its pulling with a 560ti sli.

u should be fine.

Guru3D tested with Gigabyte GeForce GTX 560 Ti (x2) @ 822 MHz core / 4000 MHz gDDR5. Those are reference design clocks.

A single MSI N560GTX-Ti HAWK draws a lot more (i.e. around 63 Watts more) power than a single reference clocked GeForce GTX 560 Ti during gaming because it's not a reference design card. If the MSI N560GTX-Ti HAWK is also being manually overclocked then you can up the power consumption further. For example, for a single MSI N560GTX-Ti HAWK, increasing the GPU clock by 50 MHz and the Memory clock by 70 MHz increases power draw by 9.1 Watts.

ht4u.net measured the actual power consumption of the

MSI N560GTX-Ti HAWK:
Maximum Card Power (FurMark): 260.20 Watts
Gaming (OC GPU:1000 MHz, Memory:1120 MHz): 224.58 Watts
Gaming @ Factory Clocks (GPU:950 MHz, Memory:1050 MHz): 215.45 Watts

NVIDIA Reference Design GeForce GTX 560 Ti:
Maximum Card Power (FurMark): 192.99 Watts
Gaming (OC GPU:940 MHz, Memory:1050 MHz): 164.84 Watts
Gaming @ Factory Clocks (GPU:822 MHz, Memory:1002 MHz): 152.79 Watts

Two MSI N560GTX-Ti HAWK in 2-way SLI is going to be drawing more power than you think.
