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?
 
850 is enough yes. Just make sure you get a good quality one and not a crappy one. You would not put a knife in yer heart don't do the same with yer psu the amount of times I see people using cheap psu makes me feel sick. I reccomend Corsair, xfx or Antec psu's myself.

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.
 
The cheapest I'd consider would be their HX range. Not exactly cheap though. Great manufacturers are also Enermax, Seasonic, Antec. XFX are also good, like the corsairs, they are based on Seasonics. I'm going to the source and getting a Seasonic X-850 next time :D
 
Yeah my previous PSU was an 400w Enermax PSU I think :)

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