Is my power supply enough?

[CarXiong]

Hi, I've just built a new rig upgrading completely from an old Core2Duo E8400 build. Everything is new except for the PSU, HDD (formatted), and Tower which was savage from the old build. The PSU is a 7 year old Antec NeoPower 650w Blue ATX12V. Everything on my build runs fine except when playing game. It would either bsod (0xa0000001) or freeze, auto quit, game crash and prompt (display driver has fail and recover). Currently the only game I'm playing is SleepingDog and I've set everything to low and at time get about 5-10min in before it goes south. I've had all proper driver install and up to date on catalyst v3.3beta. So do I have to upgrade/update my PSU as I know it lose power overtime or is it something else?

My Build:
MOBO: Asus Sabertooth 990FX R2
CPU: AMD FX8350 4.0Mhz
Ram: G.Skill Arnes 16gb (2x8gb) clock at 1866Mhz in dual channel
GPU: Asus HD7770-2GD5
HDD: Samsung 500gb 7200rpm sata 2.0
Drive: LG sata 24x DVD/CD
Case: Antec Nine Hundred V1 USB2.0
PSU: Antec NeoPower 650w Blue (Discontinued)

Here's some links to the PSU

I've also check with Asus PSU Calculator and with my build, it calculated a 600w usage.

As long as you arnt doing any OC, your PSU should be fine as far as power goes. If its 7 years old it may have degraded, and is no longer able to put out the 650w that it once did, but you'll have to check the power draw yourself.
I would suggest putting in a new PSU to check if the problem is in the draw power. Try it with another 650w and see if you bsod. If your PSU is the problem buy a new one in the 750w+ range.

How would I check the power draw? is there a program for it or would I have to do it physically? And no I don't OC, just gaming, video editing/converting/ripping, and casual usage.

You might be able to use a program to check your draw, but a more reliable way would be to buy a wall plug to test it.

I've used this kind at work before a few months ago. nice and cheap, and fairly reliable (within 2%). If you get within 50w of your total draw power you may want to think about upgrading your PSU. If you get within 15w I would strongly suggest replacing it.

If possible try to get another 650w to compare the two draws. If the newer one is pulling the same amount of power then yours is probably still in good condition, and possible to sell in case you need an upgrade.

Thank you, I'll look into that
