Can my PSU handle a GTX770?

[jocau]

I thought someone buying 770 sleeps on money. If so, then frying whole PC make little difference. He just goes and gets a new one.

To me, anything that have more than 400W, or quality 400W is enough for single card setup (single GPU). But I'm not an expert when it comes to PSU

If I would be sleeping on money, I would have bought myself a GeForce GTX TITAN, the fastest i7 CPU and 32GB RAM. But I haven't upgraded my Game PC in 2-3 years and I think it's time to upgrade my GPU since my CPU is still fine. Years ago I bought myself a GeForce 4 Ti4600 for about 540 euro, but after that card I have always bought mid-end GPU's (6600GT and 8600GT before my GTX460). This time I wanted to be a little more future-proof since I mostly play first person shooters like Crysis.

Buy a 7950 or 7970 and take the left over funds and buy a psu. IF nto just run the 770 on your current setup until it dies. Its a gaming machine that you ocassionally use. Worse case is the psu dies and it takes you a couple days to replace it.

Yes I run my GTX 770 on a 500 watt power supply.

Yo, prices for the R9 280X in Europe are not what they are in the States it seems. In the States it's a no brainer which way to go, but over seas the prices are much closer.

The GTX770 wasn't super cheap, but not super expensive either (365 euro without "same day" shipping costs).

ATI is a no-go for me because of personal experiences.

Well, I received my PSU yesterday (didn't use my new GTX770 until I received my new PSU). Everything is running fine, but I'm surprised by the temps. Idle temp is 29°C while the load temp (after playing Crysis for several hours) was only 56°C. I was expecting something like 65-70°C. The GTX770 is a bit louder than my GTX460 (both when idle and when under load), but it also seems to have the same temps as my GTX460 or even slightly better temps.

Go higher than you need always with a PSU. If you need 500w, get 650w or 750w. I'm still running a 1000w FSP (Gold rated) Aurum unit in my R9 280X box, even though I don't need more than 750w max. Couldn't be bothered changing out the PSU.

a single R280? lol depending on your cpu that system will use about 300-350 watts so a high quality 550-600 watt psu would be more than enough. yeah nothing wrong with getting quite a bit more than you need but getting a 1000 watt for any single gpu setup was darn right silly. thats just money down the drain as they usually cost significantly more than a 600 watt unit.
