I have the power! But do I have enough?

Apart from my Coolermaster Stacker and my Creative Fatality sound card I guess my PSU is the oldest part of my PC and whilst it has done me proud I'm starting to think it might be struggling a bit.

I've had a few cases where the overclock has failed when my PC reboots. Powering the PC down before starting again usually deals with that though so I'm not 100% sure what causes that. I've also had some weird gfx bugs which develop sometimes that look a bit like artifacting when a gfx card is dying or overheating but it's a new card which runs at a normal temp. Again this issue is cleared when powering down and restarting and I have seen people reporting similar issues online that disappeared after a new PSU was installed.

The PSU dates from 2006 I think and is a 620W Corsair modular PSU but can't remember the model exactly.

Currently it powers the following:

Newish O/C bundle from OCuK (2600K @ 4.6gHZ with Asus P67 Sabretooth and 4GB Ram)
MSI GTX 470
Random old 320GB hard drive
3x Samsung 1TB drives
1x CD/DVD drive
Random USB devices
2x 120mm fans
1x 80mm fan


Is a 620W PSU still more than enough for that?
 
If the PSU isn't what causes the issues then I'd have to put the gfx problems down to software/drivers more than anything else. Sometimes I notice strange issues after I have used Remote Desktop to connect to my PC from work.

As far as replacing it, if I do replace it I'd probably want to get something powerful enough for another 570 in case I decide to do some SLI fun. I assume a 850W would be enough for this?
 
Yeah my last was a Corsair so I'll probably stick with em if they have a decently priced module PSU in the wattage range I'm looking for.
 
Yeah my previous PSU was an 400w Enermax PSU I think :)

Might go look at some Enermax/Seasonic ones somewhere I guess!
