Is a 450 watt PSU Sufficient? It seems extreemly small, considering I was using 800+ watt PSU's over 6 years ago.

I have not modified my unit at all (no additional drives or upgraded cards added), and the 450 watt PSU has performed well so far. This is a well-built unit, with lots of graphics power.

I have only installed to 500 watts or more. Probably not enough power from PSU!

You need to upgrade to 500. My PSU was only 300 W and I upgraded to a 500 W Corsair unit. The PSUs aren't that expensive. I didn't want to take the chance. Haven't had any problems.

I changed my power supply after 2-3 months because I was adding a larger graphics card. Its power supply is okay but needs an upgrade after time due to low wattage.

Everything sounds good the min PSU is 500 so it's just on the border I would recommend if possessible upgrading maybe to 600 that way you don't over stress it but other than that yeah it should be fine

It sounds like you are trying to build a miner, or a HTPC. If it is a miner, it should be more than enough power. I've seen specs of mining builds with as little as 250W PSUs. However, if you are building a media server, you might want to push up the wattage to at least 550, just to be safe on the power output. On the outside, if this is a gaming machine, you might be on the low side of adequate. But, it would work. This PSU was out-of-the-box compatible with a 3rd Gen Ivy Bridge Intel processor which, at the time of my build, was what was available for my price range. So, it may work well with a Haswell or later, but I am unable to guarantee it. Hope that helps!

you may be end up getting really close to the maximum wattage for your power supply depending on the wattage of 3the rest of your system. I would recommend upgrading the PSU for this and anything in the future.

I found the wattage was not as important as the amps on the 12V rail. This card needs two 8-pin (or 6+2 pin) connectors, and my older 850 watt PSU ultimately did not have the right amps to support the card. (System kept shutting off... card had blown out the PSU.) 650 watts should be fine as long as your two 6+2 pin connectors off the 12V rail can support at least 20 amps each.

Should be fine. I have this card and a 550 watt psu and haven't had any issues since I got the card a few months ago.

You will need about 150 watts of power and a spare 6-pin PCIe power connector on your PSU. It looks like you're using a Corsair 80+ 430 watt PSU, so it should cover these.It all depends what other components you have in your system. It looks like you could with something like an Intel Core i3 or an AMD FX-4300, with a fair amount of buffer.A good place to get an estimate of how much power your PC needs would be PC Part Picker (just google it).

The card at max usage requires about 140W, so I think with a 450 Power Supply would be fine for a whole system.The card require only one extra PCIe power supply connector. My previous GTX260 requied two.

Get a larger one such as 1000 +, that will give you enough for later add-ons. Don't scrimp on the PSU at all. Over worked PSU's are not good.

I have a 700 W in my machine, so I couldn't say from experience.http://www.realhardtechx.com/index_archivos/Page362.htm recommends a 450 W PSU. So 500 W should be enough. :)

I have a 450 watt psu from cooler master. If youwant to be sasafe about get a 500-650 psu

Hmm... I think a 500W PSU would be ok, but are you overclocking the CPU? If so, then I would recommend checking the necessary wattage for the GPU. I'm using a 750W PSU, but I think other people have used less. I would research this further since I'm not 100% sure 500W would suffice. I'm sorry if I couldn't be more helpful.

Sorry for the late response, I'm currently in college. This PSU will complement your pc just fine. That's a nice set up you got by the way.

Tower pc correct? My only concern is powersupply needs 800 watts or more and if it will fit.
