Forced to use my backup PSU; Would 450W be sufficient to power my system?

My Seasonic X1050 died AGAIN (seriously, what the heck are the chances of that?). I just got it back from Seasonic's RMA department not even 2 weeks ago. I don't have any extra cash to RMA it right now, so I can't do another RMA unless I can convince Seasonic to pay for ALL the shipping. Is that even possible?

I already used that extreme PSU calculator thing, and that said 450W would be plenty, but I wanted some opinions from you guys to make sure.

My system specs:
ASRock Z77 Extreme3 Gen3
Core i7 2600K - Stock speeds
EVGA GeForce GTX 670 FTW - Factory OC
Seagate Barracuda 1TB 7200RPM - Storage
OCZ Agility 3 SSD 120GB - Boot
2 x 4GB DDR3 DIMMs @ 1333MHz

My backup unit is a Corsair VX450, I know this PSU only has 1 PCIe 6-pin, but I have a dual molex adapter, so I should still be able to power my video card.

Would it still be okay for me to play my games on Ultra like I usually do?

That's what I am thinking as well, but I've never throttled a GPU before.



That's the utility I was refering to in the OP. I wanted some opinions from other people though.

So I could put my system under a decent load and still be okay?

I'm kind of mad at Seasonic now; shipping me back a unit that immediately breaks.

bah
 


Hi - You should be OK, your PSU has 33amps on the +12v rail and 30amps is recommended for a
system with a gtx 670(snd there's a little headroom built in). I wouldn't run any PSU stress testing apps,
but you should be OK for gaming and everyday stuff.
