Both my HD and PSU started dying at the same time so I have those missing in my rig atm,

I have a http://www.newegg.ca/Product/Product.aspx?Item=N82E1681... PSU on the side that I could use in the mean time
WITH
my new Kingston HyperX 120G SSD
http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...

This is my System:
H80i Corsair Water Cooling
AMD FX 8 core 8120 CPU
16 gigs of Kingston 1333 ram
ASUS M5A97 R2.0 Mobo
Nvidia GTX660 http://www.geforce.com/hardware/desktop-gpus/geforce-gt...
24a minimum on the 12v rail.

Now that is my rig and take in to mind this Coolermaster PSU is probably 4-5 years old too but working, if that is safe or not.

If not safe I will just wait for my new warrantied psu in the mail and patient it out instead of breaking more.

My case too is a CM Storm Trooper.

Thanks for your time reading my worries,

As you seem to be aware, the CM eXtreme Power isn't the best of PSU's out there. HardwareSecrets reports that it cannot actually deliver 550W but in a bind, for a short time I would think you would be okay running it (I would try it personally). If you find you have problems with it in, then take it out and wait. Other than the PSU didn't get to 550W without issues for reviews, what it did do was acceptable as far as ripple and noise levels so you shouldn't be risking components by trying it

With 85C rated Suscon caps on the primary and 5 years of age i would derate that guy by about 30%, assume you have less than 400W of remaining capacity to work with due to everything having aged significantly and not having been good to start with. With the GTX660 pulling 140W and the 8120 pulling 125W you are going to be close to its capacity. I wouldn't recommend doing much gaming on it while your real PSU is getting RMA'd, it might not survive.

While the eXtreme power Plus series are not the worst PSU on the market they are very bad, cheaply built, over priced units. OCZ did do worse though, their elite power series had many units that were simply rebadged units of lower power levels being sold for a higher price. I will say that the worst ones belong to huntkey, hardware secrets has had 3 literally explode on them during testing...

Thanks for your knowledge, it saved me from wasting my time installing a no good psu. I sure wouldnt want to break more components.

Just a question, would anyone know the site where you can build your computer and see if your power supply is sufficient to run your set up?
This is to test and make sure my original PSU is sufficient, or if Ill have to upgrade.

There are PSU calculators out there, i haven't been able to get the outervision one to load for me recently.

How i do it is by looking at the TDP of the CPU and the GPU, that is going to be their peak power consumption, then the rest of the system will be about 100W or less, that will tell you your peak power draw, almost all of that power is going to get pulled from the 12V rail so make sure that has enough capacity to support everything. CPU TDPs are usually listed on their newegg page, you can get the GPU TDPs from the wikipedia listings

A SWAG with a good fudge factor is accurate enough to pick a PSU on.
