I need a new PSU, help?

[mantinziza]

Ive been having issues with my computer and im really beginning to think that its my power unit. When i stress test my GC i can here my tower make a noise likes its bogging down then it crashes. When it reboots the error shows up as a blue screen error and displays as a driver issue. Ive tried all the possible driver versions and performed clean installs on each one. So its kinda making sense.

Heres my build

I5- 2500 quad core sandy bridge (not oc'd)
Extreme 3 gen 3 mobo
1 old hdd with 300 gigs of storage, don't even make em anymore stickers illegible
1 other old 250 g laptop hard drive, illegible as well
GTX-570 (not oc'd)

2 dvd rw drives (i have 2 cause ones a light scribe i use for work)

3 permanent usb devices

4 4g DDR3-1333 sticks

3 120mm fans
3 95 mm fans, that i run at max speed consistently

any body got a good idea on what i should get?
at least the cheapest of what i need to run this thing smoothly?

What psu do you currently have? Something like corsair TX650 would be enough.

i only have a 550 and it aint enough

Technically, according to this:
http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-570/specifications

550 watts is the minimum for your video card, so you have met the requirements to run the card. However you may have a low quality power supply which fails to put out the labelled wattage. Let us know your power supply model.

Edit: As sayantan has replied, if looking to upgrade 650 watts is a good spot to go for, will help in future upgrades since 650 watts is usually enough for single video cards.

Your definition of cheap and your location would be helpful

550 watts from any decent line is plenty for those specs

A single 570 needs 260W on peak (furmark) so your PSU IS enough. You dont need a new one.

BUT tell us the brand/model just to be sure !
