Enough power for my GTX660?

I ordered a Gigabyte GTX660, and I'm going to get a new PSU in like a month or so. I assume my PSU should be more than enough, a GPU can't use that much power can it? - I was dead wrong. After doing lots of more research - I found that the GPU requires "minium 450W", whilst my GPU is only 400W. Will this damage my GPU or any components, in any way?

Also, this is the "rails" as shown on the label:+3,3V = 30A. +5V = 30A. +12V1=14A. +12V2=15A. -12V=0.8A. +5sb=2A. The PSU is Seasonic SS-400HT Active PFC. I also purchased a FX8320 along with my GPU.

Should I be worried?

Thanks a lot!

Simple, get a better PSU.


The problem is that I cannot get a better PSU for about 20-30days. Would I be able to use the computer with the GPU in the meantime?

I would say its fine for a short while, i really recommend you to be as cautious as you can because if the PSU goes, it takes your whole system with it. So, what i'm saying is the you CAN use it for a short while, but i don't recommend it.

Just saw that you edited your previous post, which says that recommended watt is on 430W - even that, should be fine yeah?

Haha. I edited the 'simple' to 'simply' order to not sound so condescending.

Anyways, no, i would really not recommend it. It is doable but very very very risky. I would say about 70% chance to fry your system at full load. I would suggest getting at least a good quality 550-600W PSU. I like dem corsairs.

Damn, that sucks. Going to get a PSU asap then.

Edit: You don't by any chance know some sort of way, or software that I can monitor my watt usage.
Also, when you say fry my system, is that everything, or just the PSU?

Edit2: http://uk.hardware.info/productinfo/180918/cooler-maste... Thinking about getting that what's your recommendation on that PSU, good enough or?

Thanks for the answers, appreciate it.

I get that its much more expensive than the one you listed, but the CM unit has a max stable load of up to 400W which you will regularly going over.

A power supply that is good should be one of your main focuses. Unless you want to fry the motherboard, drives, cpu etc along with the other parts. Seriously, invest in a good power supply. It may not seem like much that you get a good one, but in the long run, if a stray lightning bolt hits your house, it'll at least make sure not everything is fried.

I myself took a Corsair TX950. I dont need enthusiast level, or more than 600W, but it has to power my whole system. I dont trust a lowly power supply with that.
