Will a 600 watt power supply be enough for a radeon r9 290x video card?

my computer turned itself off and will not turn on. I'm thinking my 600 watt power supply quit. I have a newly installed radeon r9 290x video card (been using it for about 2 weeks now) and just wondered if it was too much for the power supply, if I should upgrade to a 700 or 750 power supply.

Depends on your power supply, and which 290x card.

Some 290 cards required significantly more power then the normal.

Just because there is a 600w sticker on the power supply does not it has been tested and verified that it can even output 600w, let alone sustain a 600w load.

I don't understand the question. All I know about the PSU is that it is a 600 watt. On the second answer, I assumed it was verified 600 watt when I bought computer. As far as the card, I just ordered a radeon r9 290x video card. I thought that described it, is there something else to it?

PSU's are unfortunately not always properly rated. There are many ways to measure PSU capacity. A lot of cheap brands use the maximum peak power the PSU can output, but that is dangerous since the PSU can only handle that wattage for a very sort time. Higher end units are rated at the maximum sustained load, so they can handle that load well.

If you can open up the computer and find the brand and model number, we can help you figure out what PSU it is, and what quality it is. Then we can figure out if it is properly rated, so we can figure out if it is indeed the problem or not.

Do you mean Xtreme Gear 600W? From a Cyberpower PC? You can find those under Tier 5 in the list. It is very likely the unit did fail on you, and you need a replacement. Hopefully it didn't take out anything else with it.

I'd replace it with an XFX 550W unit. It's pricier than other alternatives, but for the quality it's a hard price to match. I wouldn't go any lower than that, though, since lower wattage units are either not good enough quality in general or they just don't have enough power for a 290X.

Yeah, that's what it is. I just ordered a Cooler Master V750 – Compact 750W 80 PLUS Gold PSU with Modular Molex/SATA Cables (SLI/CrossFire Ready) from newegg. Is this good, I'm hoping. Also, when you said hope it didn't take out anything else, what else could of/would of failed?

System Power Supply Requirements for a single MSI Radeon R9 290X Gaming 4 GB
• a minimum of a 750 Watt or greater system power supply is recommended. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 47 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

XTreme Gear 600W
• OEM: HAPPY MULTI-WEALTH TECHNOLOGIES
• maximum combined +12 Volt continuous current rating: 38 Amps <===== Grossly Insufficient
• one 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== Insufficient
• Modular Output Cables: No
• Meets Official Intel Haswell Compliance: No
• No 80 PLUS Efficiency Certification

Cooler Master V750
• OEM: Enhance Electronics
• maximum combined +12 Volt continuous current rating: 62 Amps <===== More than sufficient
• four 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== More than sufficient
• Semi-Modular Output Cables: Yes
• Meets Official Intel Haswell Compliance: Yes
• 80 PLUS GOLD Efficiency Certification
• 5 Year Limited Warranty

As ko888 showed, the V750 will be more than enough :) It's a very high quality, unit, and you may even be able to do dual card configurations with it in the future.

There is a chance that when a power supply fails, it fries other components with it. That only happens with very extremely cheap units, and it often actually burns something, but it is still possible there was some damage for the rest of your components.

In the future, make sure to double check that your power supply is good quality. It is often underestimated because people don't understand it, but it is the only component that can literally fry your entire computer, so you should make sure it is good.

Make a difference in what? Games? Compute applications? PSU power usage?

Edit:
Your 77 Watt TDP CPU will draw around half as much power as an Intel Core i7 3.2GHz 130 Watt TDP processor so the Cooler Master V750 that you've selected is more than enough.

The power supply you ordered is a very good quality unit.
It will work fine with your computer. When gaming you will only use about 70%-80% of its rated output which would be its most efficient range.
Good choice and hopefully the old power supply did not kill any of your other components when it died.
The power supply is the most important part of any system ,but the most under rated and overlooked component.
Lots of good information from all of the posters in this thread. We try to help people make good informed purchase decisions even if it something they do not quite understand.
