Nvidia 9800GTX problem

[02arnoldj]

Hi all! I have just finished a build:

Alpine 850W PSU,
AMD FX8350 (8 cores @ 4.0Ghz)
Gigabyte 78LMT-USB3 Mobo,
8 GB RAM
Windows 8.1 Pro x64
Arctic Freezer cooler 13
Nvidia Geforce 9800GTX (old i know but all ive got until Radeon R9 comes)

The Nvidia card wont put out a picture to my 32" HDTV, using a DVI-HDMI cable. Yet an old Radeon 4850 works. The nvidia works in a friends old Foxconn motherboard perfectly using same Bios settings.

Any suggestions?

Thanks

Have you tried using the other DVI port?

its an old card, its probably having small compatibility issues with newer hardware....its just old... 4850 is just lucky to work..

The Alpine power supply stands out as so bad bad I wouldn't try to power a toaster with it. There should be no mysterious 'compatibility issues' since PCI-E is backwards compatible.

Theres always one isn't there, did you really have to try and have a dig about alpine. let me tell you something , An Alpine 850W PSU with 42Amps on the 12v Rail, is absolutely NO different inside than a Corsair one of the same spec buddy. Just to let you know! And its not the PSU's fault the card wont work either, ive had the same problem with an 8800GTX on an ASUS mobo with a Corsair PSU last year. Lol

Except that's a complete fallacy. Corsair rates all their units, even the lower end 'budget' units at continuous power. 42 amps on an 850w power supply should tell you something right there. The lowest end Corsair ( and I'm no Corsair fan not anymore since they began selling mediocre units as enthusiast level units. Your comparison not mine. ) that comes in an 850w model is the discontinued TX 850 with 70 12v amps. Yep 70. What do you have there 42? Guess which Corsair has 42? Well the TX550 has 45 so you don't really have an 850w power supply there do you? Every quality unit on the market supplies either all or very close to all it's rated wattage on the 12v rail alone.

Any 80 Plus certifications at all? Nope? There are 80 Plus Gold certified units I wouldn't own and although any 80 Plus cert is only a measure of efficiency and not quality any unit lacking any certification at all in 2014 is unquestionably junk. Obviously more efficiency requires higher quality parts.

Bet you have a little red switch at the back as well. What does that mean? Well it means you lack an active PFC something all quality units have had for years. Another sign of junk. What happens to junk when you stress it? Yep it blows up.

So if the Alpine can actually put out what it's rated at what you have there is a 550w power supply. Think it can do that? Me either. Since no real reviews exist there is no way to know just how bad the unit is but the fact that they don't bother to send them out for reviews tells you something too. Not something good. Voltage regulation is very likely completely out of ATX specifications and ripple and noise are also likely off the charts.

So what does that mean for you? It means you are putting 'dirty' voltage into your computer. Over time this alone will damage capacitors and VRM modules on both the motherboard and graphics card.

Last but not least your '850w' power supply has a grand total of 2 x 6pin PCI-E connectors. Since the PCI-E connection supplies 75 watts and 6 pin connectors also supply 75 watts each that give you a hugely useable 225 watts assuming the unit is capable of what it's listed at. ( Don't assume that! ) A quality 850w power supply will either have 6 x 6+2 pin connectors or 4 x 6+2 pin and 2 x 6 pin connectors. A 6+2 pin connector is capable of supplying 150 watts.

So no I'm not just 'one of those' I actually know what the hell I'm talking about. Take good advice or leave it. It's your computer.

Don't believe me? Head over to jonnyguru. They specialize in power supplies. Just ask their forums.

That post definitely matches my local dealers' opinion on Corsair PSU's, except for a few models, rest are avoid at all costs.
