Old psu problems?

[number58]

I recently upgraded my video card from a 6950 to a R9 290. My power supply is a pc power & cooling silencer 750, which is about 7 years old. It meets the wattage requirements, and has enough amps on the +12V rail. But I have been experiencing some issues.

First of all, my old gpu had an annoying coil whine sound while gaming. The new one has the same issue, but it's a bit louder. I searched online and discovered that it could be the psu causing it.

Second, I get video tdr failures occasionally, but rarely when gaming. It usually happens when waking the computer from sleep. This makes me think its a psu issue.

Basically I'm wondering if I need to upgrade the psu or try something else. And is there any risk of damaging my new gpu with this old psu.

Yeah, resume from sleep issues are usually power. I wonder if that unit had an issue for a while, just became more pronounced with the more-powerful card.

The age on yours is interesting. I don't see those going much beyond 2006.

Its one of the few parts that I'm still using from my first build in 2008. That along with my disc drive is still functioning.

I was thinking of replacing it with This.
It has less power on the +12V rail than my current one, but is 80plus gold. I've always heard good things about Seasonic units. My gpu box says 750W required, but according to some calculators I've used 650W would be fine. Any thoughts?

Those cards are pretty power hungry on the 12v rail. If the unit covers it, you should be good.
