tbh, I'm quite ignorant when it comes to PSU's. Mostly because I've never had a video card that required 6 pin power cords before. My last card was a 9800GT EE that used 75w and used no external power. Since this has happened though, I have been reading lots of threads and I am learning a ton of stuff I never knew before about PSU's.

That power supply has a -5V rail. The -5V rail was removed from the ATX12V specification in 2003. Which means this PSU's design is at least that old.

Generic half-bridge cost-down overrated disaster-waiting-to-happen crapola that shouldn't be legal to sell.

Yes, you have 16v on one rail and 14v on another. So your GPU was only getting 16 or 14v. So that took out your PSU, MB and maybe your RAM, as a Antec PSU took out my MB and RAM when it went. Shorting everything out. There were 2 piles of black dust under my RAM, ha. I should've taken a picture of it. Your GPU may be alright, mine wasn't hurt for some reason. Try it in another rig.
There's a lot of used PSUs and MBs here in the for sale section.

No. I appreciate the attempt, but please research a subject before trying to make a post about it, what you've said is completely incorrect in multiple ways. Starter being that computer SMPS are constant voltage/variable current.

Whatever. The bottom line is his PSU was to underpowered to push a hungry 275. And it probably didn't have any 6 pin PCIe cables so he had to use a 4 pin molex to power it. None of my nVidias liked 4 pin molex converted 6 pin adapters. At least they wouldn't start-up connected with them.

If you have the Ultra LifetimeSeries Pro (LSP) 650W, then that's your problem since the LSP series are a grab bag of overrated low-end parts, from Wintech, Andyson, Yue-Lin, and RSY, none of which is worth the materials it took to make it.



Not trying to be argumentative. I'm just bringing some context to the conversation.

You're absolutely right, I actually had to use 2 4 pin to 6 pin molex connectors because the PSU did not have any.

LOL, good one. But your 100% right, a quality PSU is absolutely essential, you don't necessarily need to have an 80+ gold certified 1000w diamond encrusted mini nuclear reactor, but quality and proper surge protection is essential.
